Isn't 90kn dry thrust kinda less considering j-20's weight since dry thrust and power to weight ratio is critical for 5th gen engineA report issued by the American Research Institute in early April stated that the satellite photos taken in early April showed that the Chinese Air Force had already received the second brigade of J-20 stealth fighter jets, and it is speculated that there are currently about 100 J-20 stealth fighters in China.
According to the production capacity of Chengdu Aircraft Industry Group, another 200 J-20s are expected to be equipped to the Chinese air force within five years, and an average of about 50 of them will be produced each year in the next five years, reaching a total of 300 fighters, which is basically consistent with Jin Canrong’s view.
In the face of the suppression of 500 fifth-generation aircraft in the surrounding areas, in the future, the demand for J-20 of China will be about 400 to 500, and it takes about ten years in total to produce them.
As for the engine, a J-20 fighter with WS-10 “Taihang” engines was unveiled earlier this year. Prior to this, J-20 fighters had been using Russian-made AL-31F series aero engines.
It is reported that the WS-15 engine has entered the flight test stage. It is speculated that the life of the WS-15 engine is nearly 8500 hours, the maximum thrust is expected to reach more than 90 kN, and the maximum afterburner thrust can reach 150 kN, which is at the same level as the F-119 on the F-22, the world’s first five-generation aircraft, and is the guarantee for J-20 to achieve supersonic cruise and super-conventional maneuvering.
