On the occasion of the 73rd anniversary of its establishment, AVIC Shenfei continues to provide heavy information. Recently, the official video released by Shen Fei clearly appeared the J-31B stealth fighter, which is also the first time that the J-31B has been exposed. The video shows that the J-31B carries two air-to-air missiles in the side bomb bay, which is not only the first of its kind in the world, but also means that the J-31B may be able to carry 4 short-range + 4 medium-range air-to-air missiles.
It is worth noting that the length of the J-31B side bomb bay is relatively short, as can be seen from the video, the length is only about 1.5 meters at most, and the length of the combat missiles in various countries around the world is basically more than 2 meters.
Take the example of the PL-10, the main short-range air-to-air missile of the mainland, which has a diameter of about 203 mm, a length of 3690 mm and a weight of about 199 kg. That is, the PL-10 missile is more than twice as long as the J-31B side bomb bay.
The Chinese PL-10E has the characteristics of high maneuverability and large overload, with a maximum overload of up to 60G. Using advanced infrared imaging technology, the maximum range can reach 40 kilometers, which is close to the range of medium-range missiles, and the off-axis launch angle can reach 180 degrees, and the comprehensive ability is superior to similar products in Europe and the United States.
At the same time, taking the mainland's Tianyan 90, a light medium and short-range combat missile, as an example, the Tianyan 90 missile is 1862mm long and 90mm in diameter, and the length of the Tianyan 90 also exceeds the J-31B side bomb bay.
The maximum range of the Tianyan 90 is only 6000 meters, the maximum flight overload coefficient is 20G, the maximum attack speed is 2.0M, and the maximum starting hit probability is 80%, and its performance is far inferior to that of the PL-10E.
The length of the J-31B's side bomb bay is not only significantly lower than that of the PL-10, but also lower than that of the Tianyan 9, and is roughly comparable to the Continental Avant-garde series of portable anti-aircraft missiles.
For a fifth-generation fighter like the J-31B, if the requirements for missile performance are greatly reduced in order to pursue the number of missiles carried, it is not only meaningless, but also far outweighs the loss.
In future air combat, the J-31B faces advanced fighters such as the F-35, F-15 and F-16. These fighters carry advanced medium- and short-range air-to-air missiles. Not only has a long range, but also has very strong maneuverability.
If, in order to purely pursue quantity, the J-31B side bomb bay carries a light medium and short-range combat missile similar to the Tianyan 90, this will seriously weaken the combat effectiveness of the J-31B and put the J-31B in a rather disadvantageous position in close air combat.
In order to meet the needs of future wars, the key performance of the short-range air-to-air missiles carried by the J-31B in the future will be equivalent to or more advanced than the current PL-10E.
Therefore, it is more likely that as the mainland continues to make breakthroughs in missile miniaturization, the size of the mainland's new generation of short-range air-to-air missiles has been greatly reduced, so that they can be carried in the side bomb bay of the J-31B.
In recent years, from the Hongqi 9B to the Hongqi 16EF anti-aircraft missile, China's missile miniaturization technology has continued to make breakthroughs. The launch volume of the new Hongqi 9B has been reduced by 50%, and a launch vehicle can only carry four missiles, but now it has doubled to eight.
The latest model of Hongqi-16FE, under the premise that the volume is basically unchanged, the effective range of Hongqi-16FE is 160 kilometers, which is more than double that of Hongqi-16B. At the same time, the Hongqi-16FE also adopts a new aerodynamic layout, and the performance and maneuverability have been significantly enhanced. The maximum maneuvering overload can reach 35G.
China's missile miniaturization technology continues to make breakthroughs, which will have a far-reaching impact. It will greatly increase the number of weapons carried by Chinese warships, stealth fighters, unmanned fighters and unmanned warships, and the combat power will be significantly improved.
In the future, with the continuous improvement of China's missile miniaturization technology, China will launch more new air-to-air missiles in the future, and the number of missile mounts with built-in magazines for China's J-20 and J-31 will be doubled in the future, and the combat power of China's stealth fighters will be significantly improved.
Therefore, the J-31B side bomb bay can carry two missiles, and the most noteworthy thing is not only the increase in number, but also the major breakthrough in China's missile miniaturization technology.
