有侧风时某验证机着陆品质分析

以刚体系动力学理论为基础,建立飞机、起落架六自由度全量非线性方程,根据有侧风时着陆过程中驾驶员的操纵特点,提出比较符合实际情况的操纵逻辑,以及用3个单轴操纵的驾驶员模型,通过采用分时采集、分时处理飞行状态信息和分时操纵的方式,将它们有机地综合成~个同时做三轴操纵时的驾驶员模型。最后,对所建立的人-机闭环系统模型编制了相应的仿真软件,并对某验证机进行了着陆品质分析,其结果与试飞情况比较吻合。

THE QUALITIES ANALYSIS OF SOME VERIFIER DURING LANDING TASKWITH RIGHT SIDE WIND

Based on dynamic theory of systems of rigid bodies, a six degree freedom motion equation of aircraft body and gear is formulated. The control characteristics of the pilot during landing task with right side wind are analysed. Three axes pilot maneuver logic is proposed. By the method of collecting and processing the flying stale information and controlling the aircraft at separated time, three single axis pilot control models are used to describe pilot's three axes control at one moment. Based on three axes pilot aircraft closed loop system model, the dynamic simulation software during landing task is programed. The dynamic qualities of some verifier during landing'task are evaluated, and the numerical simulation results agree well with the real flight test data.
