Is there any obvious difference between the J20 engine of ws10b and the F22 engine in the United States?
In simple terms, is a small thrust, thrust weight ratio is small, but not too much difference, ws10b afterburner thrust of 15.5 tons, has surpassed Russia's al41, is still very good, the thrust weight ratio of around 9
F-22 [PW-100] F119 engine name is F-22A, the double rotor low bypass ratio engine, using two-dimensional vector nozzle on deflection, expanding type adjustment sheet on the single nozzle and when adjusted up and down and upward or downward swing, change the exhaust stream the direction is to change the direction of the thrust. The thrust of the engine can be deflected within 20 degrees of the pitch of the aircraft, with a deflection angle of 20 degrees, and thrust and vector controlled by a digital electronic system. The main parameters: 4.826 meters long, the maximum diameter of 1.13 meters, weighing 1360 kg, the maximum thrust of 156 kn thrust weight ratio 11.7. F -20 [S-10B] engine and the F-22 engine difference is not a tiny bit.
There are two F-22 engine with thrust vectoring nozzle, and Chinese f -20 currently published pictures of view, f -20 is not installed vectoring nozzle, this technique may be China is not mature and is still in the experimental stage.
