What is the engine thrust of J20?

Conventional 16 ton, afterforce 18 ton, special fuel+vector thrust.

Thrust is the aerodynamic force generated by propeller, turbofan or turbojet engine discharging a large amount of air to the tail of aircraft. It is a function of work and a force that changes the speed of an object.

The thrust is 9000 kg, which means that the engine version can generate 9000 kg of aerodynamic force. According to 1000 kg = 9.8 N, the thrust of the engine is 88200 N.

Precautions:

Thrust vector control technology, also known as thrust steering technology, is to control the maneuvering flight of the aircraft by controlling the direction of the jet at the tail of the engine, that is, to supplement or replace the aerodynamic force generated by the traditional flight control surface to control the flight of the aircraft.

The thrust direction provided by the general aviation engine is fixed, which coincides with or forms a fixed angle with the longitudinal center of the aircraft. The thrust vector engine (mainly the aircraft) can adjust the vertical or horizontal thrust direction, which has many benefits.

For example, it can shorten the taxiing distance of the aircraft, make the aircraft more mobile, and effectively control the aircraft in the stall state. Adjusting the thrust direction can minimize the resistance of the aircraft at the angle of attack and increase the cruise flight.
