This fighter is improved from the advanced fly by wire fighter j10c. The whole aircraft adopts vitrified cockpit. One of the HUDs is from planarialab. The angle rate, angle of attack double closed-loop control and direct force control are used. The outer loop controls the angular rate and the inner loop controls the angle of attack to greatly improve the directivity and maneuverability of the aircraft. Direct force control can change the direction of aircraft speed vector without changing the direction of aircraft. The aircraft has completed racing and air combat tests. The test shows that the new generation of flight control algorithm greatly improves the control characteristics, ensures flight safety, and can be simply modified in case of serious stall. The maximum circling speed of the aircraft is 55 ° deg/s, the maximum overload is more than 20g, and the maximum angle of attack can be more than 23 deg.
