Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with specific embodiments.

[0020] Take the leading edge flap actuator as an example, using the unified maintenance equipment of the whole machine, or the maintenance equipment of the leading edge flap control system, and the leading edge flap control components, through a special maintenance method, the control system will actively make the leading edge flap The flaps are disengaged from the locked state. The specific technical content is as follows:

[0021] 1. Implement specific leading edge flap actuator maintenance functions

[0022] 1) In the maintenance equipment, design the maintenance mode or maintenance instruction for unlocking the failure protection device of the leading edge flap actuator; at the same time, care should be taken to avoid the interaction between this maintenance function and other maintenance functions;

[0023] 2) In the leading-edge flap control component, the...

Abstract

The invention belongs to aircraft rudder surface control technology, and relates to an unlocking method for a fault protection device of a rotary actuator. The invention realizes the maintenance function of the rotary actuator: in the maintenance equipment, the maintenance mode or maintenance instruction for unlocking the fault protection device of the rotary actuator is designed; at the same time, the interaction between the maintenance function and other maintenance functions is avoided. Using the unlocking method of the present invention can greatly improve the maintenance efficiency of the rudder surface of the aircraft.

Description

technical field [0001] The invention belongs to aircraft rudder surface control technology, and relates to an unlocking method for a fault protection device of a rotary actuator. Background technique [0002] The characteristic of the rotary actuator is that it can realize the rotation of the control surface from 0 to 360° in a small installation space. But in practical application, the deflection range of the control surface must be limited to protect the safety of the airframe structure. Therefore, the rotary actuator is generally equipped with a fault protection device, which is used to limit the mechanical stroke and protect the control surface from distortion and deformation. [0003] If the failsafe device is turned on due to a fault or other reasons, after the fault is eliminated, if the electrical signal is still present, the leading edge flap still cannot be deflected normally, so the failsafe device must be unlocked. In the traditional unlocking process of the le...
