摘　　要：分析飞机机翼故障对飞行性能的影响,对飞机故障后能够安全着陆或返航有着重要意义,飞机的机翼作为产生力和力矩的主要部件对飞行性能起着重要的作用。提出一种基于单纯形优化的机翼故障飞机飞行性能分析方法,建立机翼故障参数模型,根据飞机爬升转弯飞行条件进行优化配平计算,得到在不同状态下不同机翼故障的配平数据库,分析了故障后飞机的飞行性能。仿真结果表明所提算法的有效性。The wings of aircraft play an important role on the aircraft, so analysis of flight performance of wing faults is of significance for aircraft safe landing. This paper presents an analyzing method for the flight performance of fault air-craft, which is based on the Nelder-Mead optimization trimming. The wing fault parameter model is established. Then the aircraft is trimmed according to climbing turn flight conditions, and the trim databases are obtained in wing fault parameter modes on different flight conditions, and the basic flight performance is analyzed. The simulation results show the effec-tiveness of the proposed method.
