摘　　要：对于飞机运行过程中出现的飞行控制系统间歇性故障,受地面条件限制,无法真实模拟空中飞机所受气动力,在地面难以再现故障现象,给此类故障的排除造成了极大困难。针对两起奖状560 XL机型升降舵配平系统间歇性故障,通过对系统及子部件工作原理和故障现象的深入分析,并基于空气动力学原理对故障发生时升降舵及配平调整片上的气动力变化进行理论还原,实现了从原理上再现故障发生时系统各部件的工作状态及可能出现的故障现象,从而准确判断故障部件并排除了故障。本文所采用的分析方法和排故措施,为排除此类型故障提供了新思路和方法,有一定的借鉴作用。In case of intermittent flight control system failures occurring during the operation of an aircraft,limited by ground conditions,it is impossible to simulate the aerodynamic of an airplane flying in the air,and it is difficult to reproduce the failure phenomena on the ground,which makes the elimination of such failures extremely difficult.In response to two intermittent failures of the elevator trim system of the Citation 560XL aircraft,by in-depth analysis of the working principles and failure phenomena of the system and its sub-parts,and applying aerodynamic principles to theoretically restore the aerodynamic changes on the elevator and the tab at the time of failure,the working state and possible failure phenomena of each component of the system when the failures occur are theoretically reproduced,thus the faulty components are accurately identified and the faults are eliminated.The analytical methods and troubleshooting measures adopted by this article provide new ideas and methods for eliminating this type of fault and have certain reference value.
