J20 fighter details

J -20 (English: Wei Long) is the fourth generation (according to the traditional classification of the Soviet Union and the classification method of the United States after 2009) dual-engine heavy stealth fighter developed by Chengdu Aircraft Industry (Group) Co., Ltd. in China, which is used to replace J-/KOOC-0/0, J-/KOOC-0//KOOC-0/etc.

歼 -20 adopts single-seat, double-engine, full-motion, double-vertical-tail, DSI bulging inlet, duck-type pneumatic layout, inverted canard wing and pointed arch side strip. The nose and fuselage are rhombic, and the vertical tail is inclined outward. The landing gear door is designed with serrated edges, and the fuselage is painted in dark black, while the J-20(20 12) is painted in bright silver gray similar to F22. The side bomb bay adopts innovative structure, which can seal the missile launching pylon in advance and is equipped with the most advanced new air-to-air missile in China.

The first engineering verification machine made its first flight in Chengdu on 20 1 11,and on the afternoon of 20 14+02 on the J-20 with the number of 20 15.

As the fifth generation heavy stealth fighter in China, the J-20 integrates the designs of many excellent fighters in the world. These technologies include:

(1) The rhombic nose and integral gold-plated hatch cover of the American F-22 were changed from No.2011to the integral hatch cover of the F-35 with built-in ribs. It is concluded that the hatch cover is thinner, and skydiving is more timely, saving 0.3-0.4 seconds for throwing the cover.

(2) The photoelectric distributed aperture system (EODAS) of American F-35 was also integrated into the J-20 fighter by technicians. 歼 -20 is the second fighter using EODAS in the world. [8]

(3) Improved DSI inlet of American F-35 (J-20 is the inlet of the next generation adjustable DSI).

(4) The layout of the American F22 bomb bay: the lower part of the belly is the main bomb bay, and the two sides of the belly are the battle bomb bays. Not only that, in order to enhance stealth capability, the J-20 also used advanced serrated doors on the bomb bay.

(5) The canard modification of J- 10 in China (China adopted the upper anti-canard in the fifth generation, which cooperated with the lower anti-main wing on the same wing surface to produce vortex lift effect);

(6) Modification of the integrated design of the large strip wing and body adopted by many fourth-generation aircraft (such as American F/A- 18);

(7) Full-motion vertical tail of Russian T-50 (J-20 is full-motion differential vertical tail) and thrust vector (in fact, all roads lead to the same goal);

(8) Modification of the rear fuselage design of Russian MIG 1.44 (narrow-spaced twin-engine nozzles, wide-spaced extraverted twin vertical tails and ventral fins, etc.). -all belong to supersonic drag reduction measures).
