摘　　要：外场飞行时,某型飞机线加速度传感器失效导致电传操纵系统故障。该故障涉及电传操纵系统极限和俯仰通道,通道之间信号交联复杂,给故障的定位带来很大困难。通过研究线加速度传感器的工作原理、极限和俯仰通道交联关系,总结排故经验,为今后类似故障的排除提供参考和借鉴。In outfield flight,the failure of the linear acceleration sensor of a certain type of aircraft leads to the fault of the fly-by-wire control system.The fault involves the limitation of the fly-by-wire control system and the pitch control channel,and the complex cross-linking of the signals between channels brings great difficulties to the fault location.In this paper,the working principle of linear acceleration sensor and the cross-linking relationship between pitch and plate limited channels are studied and the troubleshooting experience is summarized,which provides reference for similar fault elimination in the future.
