Abstract

The embodiment of the invention discloses an actuation control method of a reverse-thrust actuation device. The reverse-thrust actuation device comprises a reverse-thrust cover cap, a control device and a control device, at least two actuators; at least two drivers; and a controller; the actuation control method comprises the following steps that the controller receives an actuation command and calculates a stop actuation position according to the actuation command; each actuation sensor obtains the current actuation position information of the corresponding actuator and feeds the current actuation position information back to the controller; the controller calculates the power to be output by the corresponding driver according to the difference value between the current actuation position and the cut-off actuation position; and the driver drives the corresponding actuator to actuate to a stop actuation position according to the required power.

Description

technical field [0001] The invention relates to the field of reverse thrust actuation of aircraft, in particular to an actuation control method of a thrust reverse actuation device. Background technique [0002] Most aircraft, especially those designed for civilian transport, incorporate thrust reversers for improved braking of the aircraft upon landing. The thrust reverser actuator is connected to the aircraft engine and can be commanded to transition from a retracted deactivated position to a deployed activated position, and vice versa, from a deployed activated position to a retracted deactivated position. In the deployed active position, the thrust reverser actuator receives the jet from the associated engine and reverses the jet, engaging it in the braking of the aircraft. [0003] The thrust reverser actuating device in the prior art usually includes a thrust reverser cover, four actuators, a driver, an actuator and a flexible transmission shaft. The flexible transmis...
