Flap and slat non-instruction motion protection verification system and verification method

Abstract

The invention discloses a flap and slat non-instruction motion protection verification system and verification method. The device comprises a flap and slat control handle, a flap and slat controller,a tester, a slat power driving device, a flap power driving device, a slat control surface, a flap control surface, a slat position sensor and a flap position sensor, wherein an instruction output bythe flap and slat controller is adjusted through the tester; and the flap and slat driving device drives the control surface to perform non-instruction motion after receiving the adjusted instruction.The test problem of the flap and slat non-instruction motion protection function of the flap and slat controller is solved, the comprehensive and reliable verification of the functional performance of the flap and slat controller is realized, and the reference of a non-instruction motion detection method is provided for other similar products.

Description

technical field [0001] The invention belongs to the technical field of detection of aircraft flight control systems, and in particular relates to a verification system and verification method for non-command movement protection of flaps and slats. Background technique [0002] Aircraft flaps and slats, as the high-lift device of the aircraft, play an important role in the take-off and landing stages of the aircraft. The control system of the flaps and slats is called a high-lift control system, and whether the high-lift control system can work normally will seriously affect the safety of the aircraft. At present, most of the functional performance testing of the slat controller, which is the core control component of the aircraft high-lift system, is already mature, but it is difficult to simulate the real non-command movement of the slat for the fault setting of the system components. There are difficulties in the verification of the function of "flaps and slat non-command...
