民用飞机非对称动力时的飞行品质研究

Handling Qualities Analysis with Asymmetry Thrust of Civil Aircraft

摘要:

民用飞机发生非对称动力飞行时,要求其能够继续安全飞行并着陆。对于双发飞行器而言,单发失效的概率较大,在此情况下,飞机必须采取相应的操纵来保持飞机安全飞行。因此,有必要对其飞行品质进行研究。通过对六自由度运动方程进行仿真计算,研究了飞机非对称动力时的操稳特性,并总结了其飞行品质的验证方法。仿真结果表明该方法是有效的,并具有一定的工程设计指导作用。

Abstract:

When the aircraft has asymmetry thrust,it must be continuing flying and landing safely. There are lots of probabilities of one engine failure with two engine aircraft. On the condition it must control to maintain the fly safe. So it is necessary to research the aircraft handling qualities. Simulate and calculate the six-degrees-of-freedom equations,research the controllability and stability of one engine inoperative aircraft and summarize the verifying ways. The simulation demonstrates the validity of the way and it has good effect on engineering design.
