Embodiment Construction

[0017] See first figure 1 , Which shows a module block diagram of an embodiment of the method according to the present invention. According to the present invention, a friendly engine maintenance man-machine interaction interface can be set on the display screen of the aircraft cockpit aeromotor onboard maintenance system, and a GMO soft switch can be set on the maintenance interface. The GMO soft switch can communicate with at least one controller that realizes reverse thrust control through a data bus, figure 1 Exemplarily shows two such controllers, the controllers can be electrically connected with the Actuation of Reverser Thrust through an electrical interface (Electrical interface), so as to make the command signal of the GMO soft switch. In response, open, for example, the three locks of the thrust reverse system to complete the work of opening the thrust reverse cover.

[0018] It is preferable to set the GMO soft switch under the Initiated Test function of the human-mac...

Abstract

The invention provides a method for opening a thrust-reversing system of a power device of an aircraft. The method comprises the following steps: providing a man-computer interaction interface of a flight motor-mounted maintenance system in a cockpit of the aircraft; setting a ground maintenance override software switch on the man-computer interaction interface; communicating the ground maintenance override software switch with at least one controller for realizing thrust-reversing control; and using the controller to receive a signal of the ground maintenance override software switch, and judging an actuator for controlling the thrust-reversing system through control logic according to the current state of an engine so as to open a thrust-reversing cover of the thrust-reversing system. According to the method disclosed by the invention, the function of the ground maintenance override switch of the thrust-reversing system is realized by adopting a soft switching way, the connection of hard wires is reduced, and the maintenance steps, the workload of ground service staff and maintenance tools are reduced.

Description

Technical field [0001] The present invention relates to a method for turning on the reverse thrust system of an aircraft power plant, in particular to a method for turning on the reverse thrust system of an aircraft power plant by using a soft switch during ground maintenance. Background technique [0002] When performing ground maintenance on the thrust reverse system of the aircraft power unit, the thrust cover needs to be opened for inspection and maintenance. This requires a separate ground maintenance override (GMO) switch, so that the reverse thrust device can open the reverse thrust cover of the reverse thrust system without meeting the normal reverse thrust control logic, so that the ground crew can check the reverse thrust system. Acting mechanism. [0003] In the prior art, a physical hard switch, that is, a ground maintenance override (GMO) switch, is usually set on the surface of the nacelle of the engine, which is connected to the engine's controller, the full authori...
