Embodiment Construction
[0020] The invention realizes the function of speed maintenance by cross-linking with the autopilot system and the engine control system
[0021] There are two methods of speed control: one is to control the elevator and change the pitch angle to achieve speed control; the other is to control the displacement of the throttle lever to change the engine tension to achieve speed control. Due to the aerodynamic coupling between the flight speed and the pitch attitude angle in the longitudinal motion of the aircraft, when the thrust is increased, it not only directly causes the increase of the flight speed, but also causes the increase of the pitch angle, and the increase of the pitch angle will lead to the increase of the flight speed. decline. Therefore, to change the flight speed, the pitch angle must be maintained. Therefore, by cross-linking the autothrottle system and the autopilot system, the decoupling between the angle and speed movement during automatic flight is realize...
