China has been the topic of F-20 caused a sensation at home and abroad, in the Chinese military, the most attention to China was undoubtedly the new weapons the U.S. military. J -20 U.S. media reports, there will always be proud of with the U.S. F-22 stealth fighters were compared, in some U.S. experts, the performance of J -20 with the U.S. military's most advanced stealth F-22 comparable aircraft may endanger the U.S. air superiority fighter.
But as Russia, places like the island, but filled with different voices, they think, F -20 . Also claimed that many important parts of China can not be mass production.
So, what is the view that closer to the truth? In order to avoid a vacuum of speculation and discussion, with examples, we had to escape, with the PK on the way to -20 F and F-22 technology and capacity to make some comparison. In the comparison before, and it takes some effort to clarify the complicated background. January 11, 2011: F-20 flight
watched friends in Chengdu, China J-20 stealth fighter was at 12:50 on January 11, 2011 or so off the first flight test, 13:11 successful landing. The entire flight process is accompanied by F-10S accomplished trainer battle, which lasted about 18 minutes, a success. Successfully completed its first flight in the F--20 after landing, a flight test off the site cheers, crowd outside the airport also suffered a sensational fireworks.
J -20 with the sky, every point of the aircraft were completely bare in front of millions of camera lens, the network also appeared in more high-definition photo. To this end, we have a topic on a single point under the ground the analysis of fuzzy pictures, you must do some correction. 【Detail】
canopy gap is almost invisible and smooth belly like a sports car no time estimates of various aircraft fuselage RCS superior level of surface treatment - or super-stealth F-22 With the emergence of the first high-resolution photos, we found amazing, different pictures of the previous fuzzy, J -20 delicate body showing a smooth, mirror-like luxury cars can learn a lesson the surface, this surface not only in China fighter jets is never see in the global aircraft is also second to none. This shows that fly into the manufacturing process and stealth coatings deposited to achieve a high standard.
stealth gray in dark blue paint (a variety of spectrum is likely to be effective) cover, the body of the rivet, the opening and the edge can not see. After a series of complex image processing, only a few glimpses of the looming side seam. Even with the king of stealth technology compared to B-2, F -20 are not much better, even slightly better.
The stealthy F-22 is much thinner coating, like lacquer general, the surface of the rivets, opening and the edge is clearly visible. Although not a stealth coating thicker, more complex to be advanced, but such a thin layer of paint, revealing the flap was obviously less than the level of stealth processing performance.
in the overall shape of the gap treatment and stealth stealth coating that the three aspects of treatment, F -20 F-22 are clearly a notch above. Our analysis of (the) topic in the estimates may be conservative - and J -20 stealth level is likely to surpass F-22, the standard is quite the worst - that is positive RCS = 0.1 square meters. (RCS, the Radar Cross-Section of the abbreviation, the Chinese interpretation of the radar reflection cross-sectional area.) 【More】 off less than 200 meters? Shocking short take-off capability Zhuhai Air Show in 2008, the canard of the J -10 shows excellent short takeoff capability, its take-off roll distance less than 280 meters, which was the Chinese military was a hot topic. According to an eyewitness description of calculation we can see the video circulated on the Internet, the first flight of the J -20 only roll about 230 meters to the sky - this is at the discretion of safety first, first flight movements in a very conservative .
Obviously, if a free hand to play, then F -20 200 meters from the ground is entirely possible. This shows the powerful engine in the F -20, side bar, duck under the combined effects of the extreme wing lift effect. 【More】 survey F -20 fighter do you think when the troops can be formal? Year 2018-2020 2020-2025 2015-2018 after 2025 years of F-22 stealth surface F-22's stealth coating, surface treatment and the opening has a gap compared to -20 F, the other, F-22 of the CARET inlet separation partition happens to be a standard cavity structure, a strong reflection of radar is far better than the so-called F -20 canard effect. Although it can be alleviated by absorbing paint, but still the soft underbelly of F-22 stealth.
B-2 stealth surface B-2 stealth deal with the surface is similar to J -20. However, as B-2 do not consider mobility, so the overall exterior design is more stealthy than the F -20 advantages.
whether the carrier-based aircraft carrier can be changed? Since J -20 with excellent short take-off ability, whether that idea, as some military enthusiasts, J -20 can be converted into a powerful heavy-duty aircraft carrier to show disdain for Haitian it?
to note that the overall selection F -20 high-speed configuration, in particular high-speed low aspect ratio wing, may make the low-altitude low-speed flight performance has been lacking, for the sea conditions in the complex approach to land in the small demand for the aircraft carrier deck, the aircraft landing speed may be overheated, the difficulty is high. J -20
so if you want to be converted into a carrier-based aircraft carrier would need to like the idea of the Navy F-22 type as high-speed airfoil aspect ratio of the change in the F-14 type of variable folding wings; or, as the F-35 Navy, as increased wing. 【Detail】
stealth technology was actually too much touted the Air Force boasts of stealth technology to the somewhat esoteric, the point of marvelous, and the public, the media's pursuit of stealth features to hide the truth just the point.
the analysis of the value of stealth aircraft before the war, it is necessary to review the concepts of stealth technology. But a relative statement stealth, nothing more than weaken, inhibit, absorb, deflect radar target echo intensity, the relative value of its existing aircraft RCS and radar system down to a lower value, in order to achieve a transparent one-way battle , one-way attack.
However, the spear and shield, racing each other and each other improve. Radar system is rapidly progressive, and because of its inherent advantages, will soon be able to go beyond the radar system, stealth technology, stealth technology experienced shift the invisible wall, stalled. 【Detail】
third-generation Russian fighter mechanical radar, According to radar theory, the effective detection range and target RCS of the fourth root (the fourth side open RCS) was directly proportional relationship. This theorem, in order to make the other side of radar detection range reduced to 1 / 2, then one's own target RCS will be reduced to the original 1 / 16.
and for fighters who, RCS reduction from 10 square meters to 1 square meters is relatively easy to do things (such as the F/A-18E/F 0.1 square meters to need a lot of stealth optimization methods (such as the F-22 and J -20 with the many ways), but down from 0.1 square meters to cut to the need for more unconventional means, and difficult to further optimize (such as the B-2 bomber).
other words, stealth and counter stealth wrestling, the ultimate winner or radar. 【More】 Revolutionary airborne active phased array radar The first third-generation fighters equipped with a mechanical scanning pulse Doppler radar, then such aircraft as the MiG -31 began with a passive phased array radar (PESA), or called passive phased array radar, its main characteristics is through an electronic array antenna, radar electronics to achieve the distribution and control, to achieve a true multi-target search and tracking capabilities.
Active Phased Array Radar (AESA), or also known as active phased array radar is the emergence of another revolutionary technological advances. It eliminates the traditional center-type high-power radar transmitters, the antenna and transmit / receive (T / R) devices into one, each antenna array element is formed by the small gallium arsenide microwave integrated circuit modules, including the complete radar beam manufacturing, transmitting and receiving functions, is a complete miniature radar.
phased array radar, in particular the active phased array (AESA) radar with the traditional mechanical scanning radar compared to a world of difference between functionality and performance, benefits and more to the point where is difficult to count them out. For aircraft performance, the most important one is to achieve a true two-point multi-target capability and the power is greatly enhanced.
AESA radar as an efficient use of microwave integrated circuits transmit / receive array elements (referred to as T / R module), the microwave energy loss is negligible, for the same installation space (the same power and antenna cover) who, AESA the effective power radiated by the radar than the machine is 10 times the radar to detect long distance 75%.
AESA radar, the advantages are: failure of some modules does not affect the overall performance, radar reliability is a leap; multi-objective multi-tasking features outstanding combination of different modules can be assigned to perform different tasks. The successful application of AESA airborne radar of traditional a revolution, she is like behind DOS computer from a variety of Windows to upgrade to the system, greatly expanded the field of radar applications and improve the radar performance, and to improve and enrich the combat aircraft mission capability and combat mode. 【More】 rapid increase detection capabilities of modern fighter radar radar integrated circuit performance can be determined with reference to Moore's Law as long as the fate of the aircraft radar power, stealth fighters still obediently betray oneself Fourth-generation stealth fighter has been able to achieve technical superiority was the essence, because the previous third-generation fighters are equipped with traditional mechanical scanning radar, the radar is generally detected at 70 km distance to the typical 3-5 meters RCS fighter target. For RCS 0.1 m2 down to 0.5 or even stealth aircraft, the radar detection range drops to about 20 kilometers, the distance is close to that of the visual - and in fact as early as the two sides close to this distance before. Three generations of fighters were behind an advanced fourth generation fighter in the long-range air to air missile fired shot down.
However, in the face of high-power AESA radar, stealth aircraft not going to work, and this aircraft radar target RCS 3-5 meters distance of up to 160 or even the discovery of more than 200 km, even stealth aircraft RCS reduced to 1 / 100 , radar detection range triple play, there are 6,70 km, enough to guide long-range air to air missile launch needs.
stealth technology and is the relationship between spear and shield, then both sides will be able to form an effective range of weapons outside of the ability to find each other, that the battlefield has become on depreciated.
So, too much emphasis on stealth aircraft performance and dependence, like shaking clever, tricky to play, play a while, could not handle a long time. 【More】 Various types of aircraft used by the U.S. radar APG-77: active phased array radar, fighter leader
APG-77 radar on the large-scale aerial target detection range as far 400--460 km, the detection of third-generation fighter distance 190--260 km proximity search capabilities and early warning aircraft. But its outstanding advantage is its low can capture technique with that using only a needle-shaped beam width of 2 degrees on the instantaneous direction of the desired objectives, frequency scanning, making almost impossible to sense the enemy F-22 radar signal. 【Detail】
APG-63V3: F-15 modification APG-79: modified F/A-18 Various types of aircraft used by the Russian radar N001: Su-27 early pulse radar N011: Su-27 radar N011M: Su-30 PESA radar N035: Su-35 AESA Radar Will be used for T-50's AESA radar Speed to become a major bargaining chip to determine the winner As said, the RCS will be reduced to the original aircraft to 10%, the radar detection range of its reduced to only 56% of the original. Even if the RCS reduced to 1% of the original, the radar detection range reduced to only 32% of the original. Easy to improve radar performance and reduce the RCS is difficult, with the rapid development of radar technology, stealth aircraft stealth increasingly unreliable, so estimates of the role of stealth technology should not be too high.
If, in the four generations of air combat unit of the three generations of machine, you can with the advantage of access to such information is not to take the lead, calmly deal with the privilege, then the fourth-generation fighter and is equipped with three generations of advanced fighter AESA radar or four generations of fighters against time, speed has become an important bargaining chip to determine the winner. Principle is to try to combat the energy to improve their own speed (kinetic energy) and height (potential energy) and the rational use of the energy advantage, cutting the opponent's height and speed advantage. 【Detail】
Beyond Visual Range combat is closely related to performance and speed of carrier aircraft first interception missile launches from the carrier aircraft when speed is essential, effective range air to air missiles is not a constant, it was the height of the two machines, the speed, the relative angular position, to what extent do mobile target actions and the performance of the missile itself, so have a relationship.
first flight of the missile itself can set machine speed range and power are closely related, if with an AIM-120 dynamic range to 80 km, the launch carrier aircraft speed to reach at least 1.4-1.6M, if subsonic When launched, the missile range to only 65 km. Secondly, after the air to air missile on the missile launch to promote the missile engines, missile engines, but generally only work a few seconds, then glide the missile relies entirely on the inertia, the more over the slow.
high-speed mobile missile to hit aircraft must maintain a very strong mobility. Rocket engine, the missile has a power-driven, and its mobility is the strongest flight. When the missile is at an advanced inertial flight, the missile has only kinetic energy but no momentum, this time the missile maneuvering to further pursue the goal, the missile will quickly reduce the remaining kinetic energy, mobility also will be greatly reduced. Usually a maximum range of the air to air missiles can not hit the target, even if such aircraft is the F -7 mobility can be avoided by this type of advanced AIM-120C missile attack (of course it also depends on the level of the pilot.) 【Detail】
actual missile BVRAC parameters than the marked distance much closer to Therefore, the missile can be fired out of the maximum distance, there is an optimal transmission range, namely the effective range. Pilots should strive to have the best missile launch from the side opened fire. Modern aircraft fire control system to provide this information for pilots, fire too early or too late, for all of the adverse BVRAC.
currently active radar air to air missiles generally have the power range of 70-80 km, but the real, can be effective against moving targets, but the effective range of 30-40 km only. In actual combat, the Air Force during the Gulf War the main power equipment is 40-50 km range AIM-7 AAM passive radar, the actual distance of 20 kilometers firing up and down. Now the U.S. military's AIM-120 active radar air missiles, in firing range of the actual confrontation, but also 25 km from top to bottom.
at this distance, the missile shortly after launch seeker can lock on to targets, carrier aircraft can after launching; missile in the engine of the leg, mobility at its best against maneuvering targets are fully grasp - This distance is just too close to the point, the missile did not hit this round, the parties will enter 10 km away from the close fighting was. 【Detail】
speed advantage is still change the rules of air combat if the performance of a missile fired by both sides fairly, then the energy of two aircraft to become an important weight in the outcome of air combat. Taller faster aircraft, missiles fired effective the end of attack range and mobility are more and more destruction, you can close and lock the first goal, set machine can then turn around to avoid; and slower will be in a dilemma situation, other lock their missiles yet, already the first approximation of the enemy's missiles, to avoid the missile hit, then the probability of their own will reduce, if not hide their own small lives more dangerous. Here, the role of the speed advantage is obvious.
shot in both sides after the missile strikes to avoid each other when the energy of the aircraft itself is more important advantage. Fighter tactical maneuver to avoid incoming missiles or action has a barrel roll maneuver, wide-angle turn, the rapid rise or fall and so on. Not difficult to see both the motor and take advantage of high altitude fighter, almost over the horizon air combat in an invincible position. . 【Detail】
Myth: Modern Air Combat is the missile simply on the radio? AAM appears, because some incorrect information, gives rise to many misunderstandings. That are now well into the era of ultra long-range air combat, as long as the pilot pressed the button, the missile went straight as an arrow to automatically target hundreds of kilometers away, the pilot turned and calmly get out, call it a day to go home.
fact, far from the evolution of modern air combat to such a degree of intelligence, air to air missile that targets can not be independent and fully autonomous flight, is not easy to hit the target. It must ensure that the seeker has been reliably intercepted target. So the real In the long-range missiles, 【Detail】
limited capacity of the missile guidance even if today's mainstream, active radar-guided medium-range air to air missiles, while claiming to Missile guidance radar in the effective distance (currently not more than 20-30 kilometers) inside the launch, the missile is still a launch pylon on or just be able to lock on to targets, carrier aircraft from the aircraft can move the natural retreat.
If the launch farther away from the target aircraft, carrier aircraft and missiles at this time can only know the location of enemy aircraft, plus aircraft at this time on the basis of calculation of heading and speed of the aircraft and extrapolated future routes. According to the parameters of the missile at this time can only be expected to block the firing range.
dramatically change the course in order to prevent enemy aircraft beyond the expected range, the missile flight, most of the stage must be to provide target aircraft radar real-time information, according to the new amendments to the intended point of interception trajectory, that carrier aircraft but also For a long time, but without the continuous exposure guidance. 【Detail】
the secret air war to win - supersonic capability relative to the previous fourth generation fighter aircraft, flight performance is in fact the biggest breakthrough in supersonic flight under combat capability.
supersonic cruise through the substance is an advanced aerodynamic design, greatly reduce supersonic drag, increase lift-drag ratio, combined with high-thrust engines with low fuel consumption and thrust vector aircraft to achieve supersonic performance leap stage, this superior performance tip of the iceberg is the supersonic cruise, and this is its meaning, and also the standard it can be one of generational reasons. 【Detail】
YF-23 supersonic capability also emphasized a more balanced overall F-22 F-22 F-119 engines power the F-35 more powerful F-135 engine supersonic cruise secret: Low aerodynamic shape, high-thrust engines Supersonic cruise aircraft that is not open faster than the premise of afterburner M1.4 (Mach number, the speed of sound) or more, and continued to fly 30 minutes of flight capability, the U.S. F-22 fighter jets said that it does not open afterburning maximum cruise speed of up to Mach 1.72. This is mainly due to its excellent low resistance aerodynamic shape, built weapons, and powerful thrust F119 engine. This is the third-generation fighter aircraft with the
F-22 supersonic cruise the enemy to make it fast, quick occupancy, a substantial increase in the missile attack area, quickly from the battlefield, out of attacks. In and F-15, F-16 flight test comparison, if the F-22 do not want to struggle and accelerate out of them, then the . Simply put, that is, four generations of machine finish the bomb run away in the distance, behind the three generations of machines, out of reach. Therefore, even if used to escape Super Tour is also very secure. 【More】 Supersonic cruise provides the basis for the supersonic motor In fact, the first fighter to achieve With the progress of the increase in engine thrust, some Super Tour around with Ma1.2 capacity). But in fact, half a century before the British
as the fourth-generation fighters of the division of standards, the supersonic cruise if so easy to be the third generation, or even first and second generation supersonic fighter aircraft to achieve, then this criterion can be thrown into the trash a long. The standard supersonic cruise just a quantitative measure of the standard, but more importantly, based on its supersonic speed, climb, hover and maneuver performance. 【More】 supersonic conditions, the supersonic missile launch AIM-9 AIM-120 missile launch F-22 F-22 mobile missile avoidance maneuver to avoid missile aerodynamic design of the final analysis, three generations of machine is not designed as a supersonic motor Tour volley over the age of 60 made the concept of But the MiG -31 Super Tour and Tour F-22 is not a super-concept. MiG -31 only super patrol capacity, virtually no supersonic mobility, generally only fly a straight line. As a bomber interceptor to intercept the invasion that there was no problem has always been the shortest straight line distance. But as a fighter with a super patrol capability, with supersonic mobility will be very important.
If the F-15 is also mounted on the F119 engine, then the number of non-afterburning M M1.2 or higher may be achieved, but its mobility is definitely not as F22, because it is still the third-generation aerodynamic design fighter level. Because of the three generations of machines such as the F-15, Su -27, its supersonic maneuverability when not good to go, hovering at an altitude of 10,000 meters will not overload greater than 3G. The F-22 hovering in the M1.7 overload when the stability of up to 6.5G, about double than the previous generation fighter aircraft. The Soviet Union only in the M0.9 -27 to achieve this level.
Why is that? Because the final analysis, aerodynamic design of three generations of machine is not designed as a supersonic motor. Cone when the shock wave supersonic flight the aircraft And this capability is only to be thrust vector, which is F-22 MiG -31 and essential difference between. 【More】 Martial arts world, only the fast is not broken Supersonic supersonic cruising ability with excellent mobility, so that aircraft can always maintain a high energy state, not only conducive to the implementation of offensive tactical mobility aircraft, but also to be rid of air combat maneuvering and to avoid air to air missile attacks.
simulation results show that: the supersonic motor can significantly reduce the effective attack range air to air missile, if the flight speed of about M1.5 5g under the conditions of the high mobility evasive action, the missile will be a significant hit rate down, or even semi-active radar guided air to air missiles (such as the AIM-7 and R-27) fighter is almost impossible to hit that target. To reduce the size of the opponent's effective attack range.
understand this result is not difficult to achieve three times the speed of sound and 30,000 meters high degree of anti-aircraft missiles have already been made, but the SR-71 is still playing hard, because of two reasons: 1, intercept a small window , almost to the point on the side outside of the range; 2, the residual energy of the missile relative lack of aircraft, is relatively easy to escape. Super-speed and high-speed patrol aircraft SR-71, although not so prominent, but the mobility is again much better than, or chance of survival than the subsonic aircraft maneuver is much higher. 【More】 Principles of aircraft required BVRAC guided relay missile seeker radar intercept capability, in addition to size and power by the transmitter, antenna diameter size limit, but also limited by the mode of the initiative has been seized from around the 15-20km. Set the detection range because the farther the greater the scope of the actual search, so far from conducive to improving search speed, the more likely miss the target, the more likely to be interference and misleading.
Therefore, the greater the effective range of the missile, containing confidential For example, the Russian R-77 missile can hit 90 kilometers, the missile flight before the 70 km have to rely on carrier aircraft constantly revised its flight path, has been to machines, self-guided missiles into the end of the stage carrier aircraft in order to Once out of enemy
Otherwise the original scope of the missile will not be able to search and lock the enemy, the expensive air to air missiles will become uncontrolled rockets can not hit until the kinetic energy of the exhaustion of the ground. 【Detail】
stealth tactical role As mentioned earlier, stealth aircraft radar will reduce the RCS found tracks from the shrink, but because the machine can use the power contained strong AESA radar detection range by effectively playing to make up for the discount. However, the already weak function of the missile's radar seeker, the enemy's stealth measures is undoubtedly worse.
aircraft scheduled for 20-25 km of conventional distance-based radars, locked away from the face of stealth targets will shrink to 7-10 km. Lock request so harsh, will greatly increase the rate of the missile miss distance will also increase the guidance contained unit distance.
the limited size of the different missiles and carrier aircraft, leaving no room layout power supply and power radar. Therefore, AESA and other response to it can not be applied. From this point of view, there are considerable stealth tactical significance. 【Detail】
response to it However, in the face of challenges and they always put forward countermeasures. The United States had launched mm prey daga dual-mode infrared focal plane imaging seeker, this will be the response to stealth fighter weapon.
stealth fighter stealth centimeter targeted airborne radar, millimeter wave radar on the less effective; millimeter-wave radar has the advantage of higher resolution, equipment, small size, light weight, the disadvantage is susceptible to air loss, the role of relatively close distance, and for the missile seeker applications, the advantage of the benefits is very prominent, but the disadvantage is not a disadvantage.
In addition, the stealth fighter can not avoid the body of the aerodynamic heating, which has almost no relief infrared stealth strategy. Focal plane imaging using high-precision infrared seeker, will also become a weapon against stealth fighters.
expected to use the new system, air to air missile seeker after the capture of the stealth fighter can return to 20 km away or more. 【Detail】
Short Range Air to Air Missile Air Combat changes caused by short-range infrared guided missile Air to air missiles are often used, referred to as IR dogfight missile, which can automatically find, with after launching, high mobility, the use of simple, relatively low cost and so on, which is widely application. The latest fourth-generation infrared-air missiles Hydra 45 products of Israel, the U.S. AIM-9X and other missiles.
old for Short Range Air to Air Missile mobility is limited. AIM-9B Sidewinder missile has a maximum motor overload 11g, the target needs to be more than just action to avoid circumvention of 3g, and if the maximum air to air missile motor overload 18g, 5g target only needs to make can avoid overload. The missile is now fighting advanced overload often more than 50g, while the overload of modern manned aircraft limit only 9g, want to avoid high overload intense close combat maneuvering missile attacks have become increasingly successful. 【Detail】

horizon within the combat is extremely dangerous and more dangerous short, with the air to air missile technology continues to progress, close combat missile jamming capability, attack, mobility, reliability is significantly improved, so that significant changes in future close combat.
large off-axis performance of the advanced combat helmet sight of missiles and match, so no need to set machine head can be aimed at enemy aircraft fired the missile that is equipped with a large off-axis angle and the MiG -21 Helmet contest in the single difference with the F-22 will not have a big imagination.
within visual range air combat equality of opportunity, mobility fighters themselves become less important, the probability of each person was shot down almost all the same. 【Detail】
Europe The so-called horizon (BVR) air combat fighter in the visual is both outside the scope of the search through the airborne detection equipment, air target detection and intercept the enemy, and in the long-range missile attack by a combat mode. Visual distance limit is generally within 10-12 km, which is the upper limit of short-range air combat, and generally BVRAC distance of 10 km. 10-50 km range air combat are called in from the air combat, air combat more than 50 kilometers is called long-distance air combat, it also includes in-the-horizon air combat and the distance from the two modes.
As mentioned above, can be achieved in the missile from the air war despite rapidly after launching from, but still easy to fall into a dangerous close-range melee. Therefore, the advanced fourth generation fighter should be pursued in the longer distance to intercept enemy aircraft, soon after the completion of guidance from the trunk to avoid close combat. 【More】 From distance to distance: high speed stamping in the long-range missile To this end, the existing mid-range air to air missile based on, with longer range, better mobility in the long-range air to air missiles, such as high-speed ramjet engine, which makes the attack range and attack speed is much larger than the existing AIM-120 medium range air to air missiles, the maximum dynamic range of over 150 km, while the actual effective range of about 80-100 km, this missile will be to Europe in 2013 with the fighter. According to foreign media estimates, China and Russia should also be in the development of a similar missile, the performance is almost the same with them.
If the aircraft is equipped with such missiles, its practical common operations is expected to reach 50-60 km from the transmitter to enter the real long-range air combat era. However, long-range air to air missiles to increase the range of not only simple, the greater challenge is how to detect and identify long-range goals, and how to improve anti-jamming capability. 【More】 The basic pattern of future air fleet large network of small first cannon in the early years of air combat mode, the air force of the air war often using a large spot of combat air formation, air combat, modern air combat, compared with the traditional, there will be intensification of the battle formation by the small and even single transition trend. Increasingly expensive modern aircraft, the Air Force continued to narrow the number of the scale, the three major powers in the Russian Air Force's fleet of heavy air and three generations of machines will be five or six times over a frame, reduced to four generations of machines a two hundred times, But with the development of long-range air to air missiles, the small as to control a large airspace formation, and increased formation of small air combat maneuvering room is conducive to the flight performance of the play, easy to play a high speed and ultra-mobile advantage. It is anticipated that a small fleet combat will be the main mode of combat operations. Usually double (four machines) radar to follow up in formation, two-plane close formation, defense and support the three machines in formation, there may even be single combat and so on. 【Detail】
Age of Network Centric Warfare Although the future air fleet will be small or single action, but in air operations will be sent out when a variety of unmanned aerial vehicles, electronic surveillance aircraft, attack aircraft, escort machine, early warning aircraft, electronic warfare aircraft, refueling aircraft, etc.
But as Russia, places like the island, but filled with different voices, they think, F -20 . Also claimed that many important parts of China can not be mass production.
So, what is the view that closer to the truth? In order to avoid a vacuum of speculation and discussion, with examples, we had to escape, with the PK on the way to -20 F and F-22 technology and capacity to make some comparison. In the comparison before, and it takes some effort to clarify the complicated background. January 11, 2011: F-20 flight
watched friends in Chengdu, China J-20 stealth fighter was at 12:50 on January 11, 2011 or so off the first flight test, 13:11 successful landing. The entire flight process is accompanied by F-10S accomplished trainer battle, which lasted about 18 minutes, a success. Successfully completed its first flight in the F--20 after landing, a flight test off the site cheers, crowd outside the airport also suffered a sensational fireworks.
J -20 with the sky, every point of the aircraft were completely bare in front of millions of camera lens, the network also appeared in more high-definition photo. To this end, we have a topic on a single point under the ground the analysis of fuzzy pictures, you must do some correction. 【Detail】
canopy gap is almost invisible and smooth belly like a sports car no time estimates of various aircraft fuselage RCS superior level of surface treatment - or super-stealth F-22 With the emergence of the first high-resolution photos, we found amazing, different pictures of the previous fuzzy, J -20 delicate body showing a smooth, mirror-like luxury cars can learn a lesson the surface, this surface not only in China fighter jets is never see in the global aircraft is also second to none. This shows that fly into the manufacturing process and stealth coatings deposited to achieve a high standard.
stealth gray in dark blue paint (a variety of spectrum is likely to be effective) cover, the body of the rivet, the opening and the edge can not see. After a series of complex image processing, only a few glimpses of the looming side seam. Even with the king of stealth technology compared to B-2, F -20 are not much better, even slightly better.
The stealthy F-22 is much thinner coating, like lacquer general, the surface of the rivets, opening and the edge is clearly visible. Although not a stealth coating thicker, more complex to be advanced, but such a thin layer of paint, revealing the flap was obviously less than the level of stealth processing performance.
in the overall shape of the gap treatment and stealth stealth coating that the three aspects of treatment, F -20 F-22 are clearly a notch above. Our analysis of (the) topic in the estimates may be conservative - and J -20 stealth level is likely to surpass F-22, the standard is quite the worst - that is positive RCS = 0.1 square meters. (RCS, the Radar Cross-Section of the abbreviation, the Chinese interpretation of the radar reflection cross-sectional area.) 【More】 off less than 200 meters? Shocking short take-off capability Zhuhai Air Show in 2008, the canard of the J -10 shows excellent short takeoff capability, its take-off roll distance less than 280 meters, which was the Chinese military was a hot topic. According to an eyewitness description of calculation we can see the video circulated on the Internet, the first flight of the J -20 only roll about 230 meters to the sky - this is at the discretion of safety first, first flight movements in a very conservative .
Obviously, if a free hand to play, then F -20 200 meters from the ground is entirely possible. This shows the powerful engine in the F -20, side bar, duck under the combined effects of the extreme wing lift effect. 【More】 survey F -20 fighter do you think when the troops can be formal? Year 2018-2020 2020-2025 2015-2018 after 2025 years of F-22 stealth surface F-22's stealth coating, surface treatment and the opening has a gap compared to -20 F, the other, F-22 of the CARET inlet separation partition happens to be a standard cavity structure, a strong reflection of radar is far better than the so-called F -20 canard effect. Although it can be alleviated by absorbing paint, but still the soft underbelly of F-22 stealth.
B-2 stealth surface B-2 stealth deal with the surface is similar to J -20. However, as B-2 do not consider mobility, so the overall exterior design is more stealthy than the F -20 advantages.
whether the carrier-based aircraft carrier can be changed? Since J -20 with excellent short take-off ability, whether that idea, as some military enthusiasts, J -20 can be converted into a powerful heavy-duty aircraft carrier to show disdain for Haitian it?
to note that the overall selection F -20 high-speed configuration, in particular high-speed low aspect ratio wing, may make the low-altitude low-speed flight performance has been lacking, for the sea conditions in the complex approach to land in the small demand for the aircraft carrier deck, the aircraft landing speed may be overheated, the difficulty is high. J -20
so if you want to be converted into a carrier-based aircraft carrier would need to like the idea of the Navy F-22 type as high-speed airfoil aspect ratio of the change in the F-14 type of variable folding wings; or, as the F-35 Navy, as increased wing. 【Detail】
stealth technology was actually too much touted the Air Force boasts of stealth technology to the somewhat esoteric, the point of marvelous, and the public, the media's pursuit of stealth features to hide the truth just the point.
the analysis of the value of stealth aircraft before the war, it is necessary to review the concepts of stealth technology. But a relative statement stealth, nothing more than weaken, inhibit, absorb, deflect radar target echo intensity, the relative value of its existing aircraft RCS and radar system down to a lower value, in order to achieve a transparent one-way battle , one-way attack.
However, the spear and shield, racing each other and each other improve. Radar system is rapidly progressive, and because of its inherent advantages, will soon be able to go beyond the radar system, stealth technology, stealth technology experienced shift the invisible wall, stalled. 【Detail】
third-generation Russian fighter mechanical radar, According to radar theory, the effective detection range and target RCS of the fourth root (the fourth side open RCS) was directly proportional relationship. This theorem, in order to make the other side of radar detection range reduced to 1 / 2, then one's own target RCS will be reduced to the original 1 / 16.
and for fighters who, RCS reduction from 10 square meters to 1 square meters is relatively easy to do things (such as the F/A-18E/F 0.1 square meters to need a lot of stealth optimization methods (such as the F-22 and J -20 with the many ways), but down from 0.1 square meters to cut to the need for more unconventional means, and difficult to further optimize (such as the B-2 bomber).
other words, stealth and counter stealth wrestling, the ultimate winner or radar. 【More】 Revolutionary airborne active phased array radar The first third-generation fighters equipped with a mechanical scanning pulse Doppler radar, then such aircraft as the MiG -31 began with a passive phased array radar (PESA), or called passive phased array radar, its main characteristics is through an electronic array antenna, radar electronics to achieve the distribution and control, to achieve a true multi-target search and tracking capabilities.
Active Phased Array Radar (AESA), or also known as active phased array radar is the emergence of another revolutionary technological advances. It eliminates the traditional center-type high-power radar transmitters, the antenna and transmit / receive (T / R) devices into one, each antenna array element is formed by the small gallium arsenide microwave integrated circuit modules, including the complete radar beam manufacturing, transmitting and receiving functions, is a complete miniature radar.
phased array radar, in particular the active phased array (AESA) radar with the traditional mechanical scanning radar compared to a world of difference between functionality and performance, benefits and more to the point where is difficult to count them out. For aircraft performance, the most important one is to achieve a true two-point multi-target capability and the power is greatly enhanced.
AESA radar as an efficient use of microwave integrated circuits transmit / receive array elements (referred to as T / R module), the microwave energy loss is negligible, for the same installation space (the same power and antenna cover) who, AESA the effective power radiated by the radar than the machine is 10 times the radar to detect long distance 75%.
AESA radar, the advantages are: failure of some modules does not affect the overall performance, radar reliability is a leap; multi-objective multi-tasking features outstanding combination of different modules can be assigned to perform different tasks. The successful application of AESA airborne radar of traditional a revolution, she is like behind DOS computer from a variety of Windows to upgrade to the system, greatly expanded the field of radar applications and improve the radar performance, and to improve and enrich the combat aircraft mission capability and combat mode. 【More】 rapid increase detection capabilities of modern fighter radar radar integrated circuit performance can be determined with reference to Moore's Law as long as the fate of the aircraft radar power, stealth fighters still obediently betray oneself Fourth-generation stealth fighter has been able to achieve technical superiority was the essence, because the previous third-generation fighters are equipped with traditional mechanical scanning radar, the radar is generally detected at 70 km distance to the typical 3-5 meters RCS fighter target. For RCS 0.1 m2 down to 0.5 or even stealth aircraft, the radar detection range drops to about 20 kilometers, the distance is close to that of the visual - and in fact as early as the two sides close to this distance before. Three generations of fighters were behind an advanced fourth generation fighter in the long-range air to air missile fired shot down.
However, in the face of high-power AESA radar, stealth aircraft not going to work, and this aircraft radar target RCS 3-5 meters distance of up to 160 or even the discovery of more than 200 km, even stealth aircraft RCS reduced to 1 / 100 , radar detection range triple play, there are 6,70 km, enough to guide long-range air to air missile launch needs.
stealth technology and is the relationship between spear and shield, then both sides will be able to form an effective range of weapons outside of the ability to find each other, that the battlefield has become on depreciated.
So, too much emphasis on stealth aircraft performance and dependence, like shaking clever, tricky to play, play a while, could not handle a long time. 【More】 Various types of aircraft used by the U.S. radar APG-77: active phased array radar, fighter leader
APG-77 radar on the large-scale aerial target detection range as far 400--460 km, the detection of third-generation fighter distance 190--260 km proximity search capabilities and early warning aircraft. But its outstanding advantage is its low can capture technique with that using only a needle-shaped beam width of 2 degrees on the instantaneous direction of the desired objectives, frequency scanning, making almost impossible to sense the enemy F-22 radar signal. 【Detail】

Even if the RCS reduced to 1% of the original, the radar detection range reduced to only 32% of the original. Easy to improve radar performance and reduce the RCS is difficult, with the rapid development of radar technology, stealth aircraft stealth increasingly unreliable, so estimates of the role of stealth technology should not be too high.
If, in the four generations of air combat unit of the three generations of machine, you can with the advantage of access to such information is not to take the lead, calmly deal with the privilege, then the fourth-generation fighter and is equipped with three generations of advanced fighter AESA radar or four generations of fighters against time, speed has become an important bargaining chip to determine the winner. Principle is to try to combat the energy to improve their own speed (kinetic energy) and height (potential energy) and the rational use of the energy advantage, cutting the opponent's height and speed advantage. 【Detail】
Beyond Visual Range combat is closely related to performance and speed of carrier aircraft first interception missile launches from the carrier aircraft when speed is essential, effective range air to air missiles is not a constant, it was the height of the two machines, the speed, the relative angular position, to what extent do mobile target actions and the performance of the missile itself, so have a relationship.
first flight of the missile itself can set machine speed range and power are closely related, if with an AIM-120 dynamic range to 80 km, the launch carrier aircraft speed to reach at least 1.4-1.6M, if subsonic When launched, the missile range to only 65 km. Secondly, after the air to air missile on the missile launch to promote the missile engines, missile engines, but generally only work a few seconds, then glide the missile relies entirely on the inertia, the more over the slow.
high-speed mobile missile to hit aircraft must maintain a very strong mobility. Rocket engine, the missile has a power-driven, and its mobility is the strongest flight. When the missile is at an advanced inertial flight, the missile has only kinetic energy but no momentum, this time the missile maneuvering to further pursue the goal, the missile will quickly reduce the remaining kinetic energy, mobility also will be greatly reduced. Usually a maximum range of the air to air missiles can not hit the target, even if such aircraft is the F -7 mobility can be avoided by this type of advanced AIM-120C missile attack (of course it also depends on the level of the pilot.) 【Detail】
actual missile BVRAC parameters than the marked distance much closer to Therefore, the missile can be fired out of the maximum distance, there is an optimal transmission range, namely the effective range. Pilots should strive to have the best missile launch from the side opened fire. Modern aircraft fire control system to provide this information for pilots, fire too early or too late, for all of the adverse BVRAC.
currently active radar air to air missiles generally have the power range of 70-80 km, but the real, can be effective against moving targets, but the effective range of 30-40 km only. In actual combat, the Air Force during the Gulf War the main power equipment is 40-50 km range AIM-7 AAM passive radar, the actual distance of 20 kilometers firing up and down. Now the U.S. military's AIM-120 active radar air missiles, in firing range of the actual confrontation, but also 25 km from top to bottom.
at this distance, the missile shortly after launch seeker can lock on to targets, carrier aircraft can after launching; missile in the engine of the leg, mobility at its best against maneuvering targets are fully grasp - This distance is just too close to the point, the missile did not hit this round, the parties will enter 10 km away from the close fighting was. 【Detail】
speed advantage is still change the rules of air combat if the performance of a missile fired by both sides fairly, then the energy of two aircraft to become an important weight in the outcome of air combat. Taller faster aircraft, missiles fired effective the end of attack range and mobility are more and more destruction, you can close and lock the first goal, set machine can then turn around to avoid; and slower will be in a dilemma situation, other lock their missiles yet, already the first approximation of the enemy's missiles, to avoid the missile hit, then the probability of their own will reduce, if not hide their own small lives more dangerous. Here, the role of the speed advantage is obvious.
shot in both sides after the missile strikes to avoid each other when the energy of the aircraft itself is more important advantage. Fighter tactical maneuver to avoid incoming missiles or action has a barrel roll maneuver, wide-angle turn, the rapid rise or fall and so on. Not difficult to see both the motor and take advantage of high altitude fighter, almost over the horizon air combat in an invincible position. . 【Detail】
Myth: Modern Air Combat is the missile simply on the radio? AAM appears, because some incorrect information, gives rise to many misunderstandings. That are now well into the era of ultra long-range air combat, as long as the pilot pressed the button, the missile went straight as an arrow to automatically target hundreds of kilometers away, the pilot turned and calmly get out, call it a day to go home.
fact, far from the evolution of modern air combat to such a degree of intelligence, air to air missile that targets can not be independent and fully autonomous flight, is not easy to hit the target. It must ensure that the seeker has been reliably intercepted target. So the real In the long-range missiles, 【Detail】
limited capacity of the missile guidance even if today's mainstream, active radar-guided medium-range air to air missiles, while claiming to Missile guidance radar in the effective distance (currently not more than 20-30 kilometers) inside the launch, the missile is still a launch pylon on or just be able to lock on to targets, carrier aircraft from the aircraft can move the natural retreat.
If the launch farther away from the target aircraft, carrier aircraft and missiles at this time can only know the location of enemy aircraft, plus aircraft at this time on the basis of calculation of heading and speed of the aircraft and extrapolated future routes. According to the parameters of the missile at this time can only be expected to block the firing range.
dramatically change the course in order to prevent enemy aircraft beyond the expected range, the missile flight, most of the stage must be to provide target aircraft radar real-time information, according to the new amendments to the intended point of interception trajectory, that carrier aircraft but also For a long time, but without the continuous exposure guidance. 【Detail】
the secret air war to win - supersonic capability relative to the previous fourth generation fighter aircraft, flight performance is in fact the biggest breakthrough in supersonic flight under combat capability.
supersonic cruise through the substance is an advanced aerodynamic design, greatly reduce supersonic drag, increase lift-drag ratio, combined with high-thrust engines with low fuel consumption and thrust vector aircraft to achieve supersonic performance leap stage, this superior performance tip of the iceberg is the supersonic cruise, and this is its meaning, and also the standard it can be one of generational reasons. 【Detail】
YF-23 supersonic capability also emphasized a more balanced overall F-22 F-22 F-119 engines power the F-35 more powerful F-135 engine supersonic cruise secret: Low aerodynamic shape, high-thrust engines Supersonic cruise aircraft that is not open faster than the premise of afterburner M1.4 (Mach number, the speed of sound) or more, and continued to fly 30 minutes of flight capability, the U.S. F-22 fighter jets said that it does not open afterburning maximum cruise speed of up to Mach 1.72. This is mainly due to its excellent low resistance aerodynamic shape, built weapons, and powerful thrust F119 engine. This is the third-generation fighter aircraft with the
F-22 supersonic cruise the enemy to make it fast, quick occupancy, a substantial increase in the missile attack area, quickly from the battlefield, out of attacks. In and F-15, F-16 flight test comparison, if the F-22 do not want to struggle and accelerate out of them, then the . Simply put, that is, four generations of machine finish the bomb run away in the distance, behind the three generations of machines, out of reach. Therefore, even if used to escape Super Tour is also very secure. 【More】 Supersonic cruise provides the basis for the supersonic motor In fact, the first fighter to achieve With the progress of the increase in engine thrust, some Super Tour around with Ma1.2 capacity). But in fact, half a century before the British
as the fourth-generation fighters of the division of standards, the supersonic cruise if so easy to be the third generation, or even first and second generation supersonic fighter aircraft to achieve, then this criterion can be thrown into the trash a long. The standard supersonic cruise just a quantitative measure of the standard, but more importantly, based on its supersonic speed, climb, hover and maneuver performance. 【More】 supersonic conditions, the supersonic missile launch AIM-9 AIM-120 missile launch F-22 F-22 mobile missile avoidance maneuver to avoid missile aerodynamic design of the final analysis, three generations of machine is not designed as a supersonic motor Tour volley over the age of 60 made the concept of But the MiG -31 Super Tour and Tour F-22 is not a super-concept. MiG -31 only super patrol capacity, virtually no supersonic mobility, generally only fly a straight line. As a bomber interceptor to intercept the invasion that there was no problem has always been the shortest straight line distance. But as a fighter with a super patrol capability, with supersonic mobility will be very important.
If the F-15 is also mounted on the F119 engine, then the number of non-afterburning M M1.2 or higher may be achieved, but its mobility is definitely not as F22, because it is still the third-generation aerodynamic design fighter level. Because of the three generations of machines such as the F-15, Su -27, its supersonic maneuverability when not good to go, hovering at an altitude of 10,000 meters will not overload greater than 3G. The F-22 hovering in the M1.7 overload when the stability of up to 6.5G, about double than the previous generation fighter aircraft. The Soviet Union only in the M0.9 -27 to achieve this level.
Why is that? Because the final analysis, aerodynamic design of three generations of machine is not designed as a supersonic motor. Cone when the shock wave supersonic flight the aircraft And this capability is only to be thrust vector, which is F-22 MiG -31 and essential difference between. 【More】 Martial arts world, only the fast is not broken Supersonic supersonic cruising ability with excellent mobility, so that aircraft can always maintain a high energy state, not only conducive to the implementation of offensive tactical mobility aircraft, but also to be rid of air combat maneuvering and to avoid air to air missile attacks.
simulation results show that: the supersonic motor can significantly reduce the effective attack range air to air missile, if the flight speed of about M1.5 5g under the conditions of the high mobility evasive action, the missile will be a significant hit rate down, or even semi-active radar guided air to air missiles (such as the AIM-7 and R-27) fighter is almost impossible to hit that target. To reduce the size of the opponent's effective attack range.
understand this result is not difficult to achieve three times the speed of sound and 30,000 meters high degree of anti-aircraft missiles have already been made, but the SR-71 is still playing hard, because of two reasons: 1, intercept a small window , almost to the point on the side outside of the range; 2, the residual energy of the missile relative lack of aircraft, is relatively easy to escape. Super-speed and high-speed patrol aircraft SR-71, although not so prominent, but the mobility is again much better than, or chance of survival than the subsonic aircraft maneuver is much higher. 【More】 Principles of aircraft required BVRAC guided relay missile seeker radar intercept capability, in addition to size and power by the transmitter, antenna diameter size limit, but also limited by the mode of the initiative has been seized from around the 15-20km. Set the detection range because the farther the greater the scope of the actual search, so far from conducive to improving search speed, the more likely miss the target, the more likely to be interference and misleading.
Therefore, the greater the effective range of the missile, containing confidential For example, the Russian R-77 missile can hit 90 kilometers, the missile flight before the 70 km have to rely on carrier aircraft constantly revised its flight path, has been to machines, self-guided missiles into the end of the stage carrier aircraft in order to Once out of enemy
Otherwise the original scope of the missile will not be able to search and lock the enemy, the expensive air to air missiles will become uncontrolled rockets can not hit until the kinetic energy of the exhaustion of the ground. 【Detail】
stealth tactical role As mentioned earlier, stealth aircraft radar will reduce the RCS found tracks from the shrink, but because the machine can use the power contained strong AESA radar detection range by effectively playing to make up for the discount. However, the already weak function of the missile's radar seeker, the enemy's stealth measures is undoubtedly worse.
aircraft scheduled for 20-25 km of conventional distance-based radars, locked away from the face of stealth targets will shrink to 7-10 km. Lock request so harsh, will greatly increase the rate of the missile miss distance will also increase the guidance contained unit distance.
the limited size of the different missiles and carrier aircraft, leaving no room layout power supply and power radar. Therefore, AESA and other response to it can not be applied. From this point of view, there are considerable stealth tactical significance. 【Detail】
response to it However, in the face of challenges and they always put forward countermeasures. The United States had launched mm prey daga dual-mode infrared focal plane imaging seeker, this will be the response to stealth fighter weapon.
stealth fighter stealth centimeter targeted airborne radar, millimeter wave radar on the less effective; millimeter-wave radar has the advantage of higher resolution, equipment, small size, light weight, the disadvantage is susceptible to air loss, the role of relatively close distance, and for the missile seeker applications, the advantage of the benefits is very prominent, but the disadvantage is not a disadvantage.
In addition, the stealth fighter can not avoid the body of the aerodynamic heating, which has almost no relief infrared stealth strategy. Focal plane imaging using high-precision infrared seeker, will also become a weapon against stealth fighters.
expected to use the new system, air to air missile seeker after the capture of the stealth fighter can return to 20 km away or more. 【Detail】
Short Range Air to Air Missile Air Combat changes caused by short-range infrared guided missile Air to air missiles are often used, referred to as IR dogfight missile, which can automatically find, with after launching, high mobility, the use of simple, relatively low cost and so on, which is widely application. The latest fourth-generation infrared-air missiles Hydra 45 products of Israel, the U.S. AIM-9X and other missiles.

within visual range air combat equality of opportunity, mobility fighters themselves become less important, the probability of each person was shot down almost all the same. 【Detail】
Europe The so-called horizon (BVR) air combat fighter in the visual is both outside the scope of the search through the airborne detection equipment, air target detection and intercept the enemy, and in the long-range missile attack by a combat mode. Visual distance limit is generally within 10-12 km, which is the upper limit of short-range air combat, and generally BVRAC distance of 10 km. 10-50 km range air combat are called in from the air combat, air combat more than 50 kilometers is called long-distance air combat, it also includes in-the-horizon air combat and the distance from the two modes.
As mentioned above, can be achieved in the missile from the air war despite rapidly after launching from, but still easy to fall into a dangerous close-range melee. Therefore, the advanced fourth generation fighter should be pursued in the longer distance to intercept enemy aircraft, soon after the completion of guidance from the trunk to avoid close combat. 【More】 From distance to distance: high speed stamping in the long-range missile To this end, the existing mid-range air to air missile based on, with longer range, better mobility in the long-range air to air missiles, such as high-speed ramjet engine, which makes the attack range and attack speed is much larger than the existing AIM-120 medium range air to air missiles, the maximum dynamic range of over 150 km, while the actual effective range of about 80-100 km, this missile will be to Europe in 2013 with the fighter. According to foreign media estimates, China and Russia should also be in the development of a similar missile, the performance is almost the same with them.
If the aircraft is equipped with such missiles, its practical common operations is expected to reach 50-60 km from the transmitter to enter the real long-range air combat era. However, long-range air to air missiles to increase the range of not only simple, the greater challenge is how to detect and identify long-range goals, and how to improve anti-jamming capability. 【More】 The basic pattern of future air fleet large network of small first cannon in the early years of air combat mode, the air force of the air war often using a large spot of combat air formation, air combat, modern air combat, compared with the traditional, there will be intensification of the battle formation by the small and even single transition trend. Increasingly expensive modern aircraft, the Air Force continued to narrow the number of the scale, the three major powers in the Russian Air Force's fleet of heavy air and three generations of machines will be five or six times over a frame, reduced to four generations of machines a two hundred times, But with the development of long-range air to air missiles, the small as to control a large airspace formation, and increased formation of small air combat maneuvering room is conducive to the flight performance of the play, easy to play a high speed and ultra-mobile advantage.
