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...

Abstract

The invention discloses an automatic throttle system of a screw propeller type transport aircraft. The system is cross-linked with an automatic pilot system and a mechanical engine control system, thus the control over the flight speed is realized, and requirements for control over speed stability and track angles during automatic flight especially in the low dynamic pressure situation are met. The system comprises a throttle servo controller, throttle actuators, a display control board, a quick break switch and the like. The system is simple, reliable, and convenient to operate.

Description

technical field [0001] The invention belongs to the field of aviation technology, and relates to an aircraft automatic throttle system. Specifically, it realizes the function of automatically maintaining the flight speed of the aircraft, and is mainly applied to propeller-type large and medium-sized transport aircraft and civil aircraft. Background technique [0002] The propeller-type large and medium-sized transport aircraft can realize automatic flight control through the autopilot system, reducing the workload of the driver. Since this automatic flight control system does not have an automatic throttle system, it cannot be cross-linked with the autopilot system and the mechanical engine control system to control the flight speed. Track angle control requirements. Contents of the invention [0003] (1) Purpose of the invention [0004] The present invention overcomes the shortcomings of the existing automatic flight control system for propeller-type large and medium-s...
