飞机方向舵故障建模与侧风着陆仿真

基于风洞试验数据和CFD数据,建立了某型飞机上、下两片方向舵在松浮、卡滞和脱落等故障的数学模型;针对方向舵脱落故障,在飞行模拟器上进行了人在环的侧风着陆仿真试验,验证了模型的准确性,得到了与实际侧风响应相吻合的故障模型;最后,基于此模型探讨了方向舵故障下的侧风着陆安全性与驾驶员负荷.

Modeling of aircraft rudder faults and simulation of landing in crosswind

Based on the data of wind tunnel experiments and CFD,the model of some aircraft's rudder faults is built,such as loosing,jamming and falling off of each rudder.By conducting pilot-in-loop simulation tests with the rudder falling off using a high-level flight simulator,this paper verifies the accuracy of the model.The fault models matching the crosswind response are also given.In the end,this paper discusses the safety of landing and pilot load in the crosswind with the rudder failed.
