Problems solved by technology

Since only the wings of the aircraft, the movable surface of the empennage, the actuators of each movable surface and the position sensor of the rudder surface are installed in the part-installation stage, and the related computer products in the flight control system are not installed, the telex control mode cannot be used To carry out the adjustment and inspection of the movable airfoil, the actuator can only be in the damping working mode, and the deflection of the rudder surface is carried out by manually loading the external force. This method relies too much on manual operation experience. damage, in

Abstract

The invention discloses an aircraft movable airfoil adjustment detection system and method. The system includes a signal conditioning box, a board card plug-in box, an integrated control computer, a programmable power supply, a displayer and a matched cable. The signal conditioning box is used for fault positioning and metering of the aircraft movable airfoil adjustment detection system, the matched cable is connected with the signal conditioning box and actuators and control plane position sensors on the airfoils and emages, the board card plug-in box provides a required excited signal to drive the actuators to do concertina movement after a work command is adjusted, and the integrated control computer sends an operating personnel command through a human-computer interaction interface tocontrol the movable airfoils to move and feeds back the motion states of the airfoils to a software interface, so that adjustment and detection of secondary airfoils, spoilers, secondary airfoil position sensors, an elevator, a rudder and an elevator position sensor are completed.

Description

technical field [0001] The invention relates to an aircraft movable wing surface testing technology, in particular to a system and method for adjusting and detecting the movable wing surface in the assembly stage of aircraft components. Background technique [0002] The movable wing surface of the aircraft refers to the wing surface on the wing and tail that can be controlled by manipulation, mainly including elevators, ailerons, rudders, spoilers, etc. The fly-by-wire flight control system realizes the aircraft by manipulating the deflection of each movable wing surface of the aircraft. The control of attitude and heading, and the change of small parameters on the wing surface will affect the flight attitude, so the movable wing surface is an important part related to the flight safety of the aircraft. [0003] In the production stage of the aircraft, due to factors such as manufacturing and assembly processes, there will be a certain cumulative error. If the adjustment and...
