In a blink of an eye, 2022 is almost over again. The legendary WS-15 engine , which is standard for J-20 , has never been heard from except for the suspected blurry picture in the previous one.
suspected to be a fuzzy picture of WS-15
It is gratifying that on the 12th, there has been new progress on WS-15:
From the picture, the J-20 dual-engine both have been replaced with a new vector nozzle engine. The convergence plate of the engine nozzle is clearly different from the zigzag Taihang modified engine equipped in front of the J-20, or the Taihang vector engine equipped in the J-10B.
From the perspective of the number of convergent pieces, the number of convergent pieces modified by the J-20 was originally equipped with 18 pieces; the number of convergent pieces of the J-10B Taihang modified vector engine is 15 pieces. The number of convergence plates of the new engine that appeared this time seems to be about 14, which is closer to the Taihang vector engine of the J-10B. In terms of appearance, it is also closer to the Taihang vector engine of the J-10B.
2018, Academician Liu Daxiang said that WS-15 will be finalized within 3-5 years. Calculate the time, even if the WS-15 progress is slower and even if it is delayed, it should be the later stage of the flight test. In this way, WS-15 should be officially revealed, even if it is a little blurry.
From the picture, this J-20 is still undergoing tests of plug-in composite hangers. There are 4 heavy hang points under the J-20 wing. When 2 large 2400-liter fuel tanks are mounted, 2 composite hangers can also be mounted. In this way, through external plug-ins, the number of medium and long-range air-to-air missiles can be doubled (8 pieces) while significantly increasing the combat radius. At the same time, the J-20 can also carry 4 PL-XX ultra-long-range air-to-air missiles with a longer range like the J-16 to achieve more combat functions.
Speaking of which, this picture appears too suddenly and too clear, and it is as clear as P picture, making people wonder. But no matter what, it's time for turbofan 15 to appear officially. Only after
is replaced with WS-15, the J-20 has truly reached its full capacity. Its advantages of super patrol and super maneuverability will be fully utilized. The J-20, which was not equipped with WS-15, abused the J-16 and Su-35 in various confrontation exercises, and was believed by the US to surpass the F-22 in many performances. What level will the J-20 after changing into WS-15 reach?
