AIRCRAFT TURNING OVER-TRAVEL DETECTION DEVICE

摘要

An aircraft turning over-travel detection device (100) comprises: an over-travel push rod (20) and a detection assembly, the detection assembly comprising a target (40), a proximity sensor (30), a sleeve (60), an energy storage spring (50), a connecting rod (70) and a linkage clamp hook (80). When a turning over-travel occurs, the over-travel push rod (20) releases the linkage clamp hook (80) to loosen the connecting rod (70), the connecting rod (70) drives the target (40) to move towards the proximity sensor (30) under the action of the energy storage spring (50), and the proximity sensor (30) detects the position of the target (40), and transmits a signal to an aircraft control system. The aircraft turning over-travel detection device easily detects a turning over-travel, and does not easily generate misdetection and false alarm; it does not damage a target during a detection process, and a state in which an over-travel occurs is locked in a mechanical mode; and it is easy for the aircraft crew to discover a turning over-travel, and can perform manual reset.
