各扰动对舰载机着舰过程的影响分析

舰载机在着舰过程中会有很多扰动,如果不能很好地控制,消除扰动很可能会机毁人亡.通过比较分析出扰动中对着舰影响最大的扰动,就能够对其采取相应的措施以抑制扰动.使用力平衡方程搭建系统在进行Simulink上仿真,分析各种气流扰动和甲板扰动对舰载机着舰的影响.研究中均基于简单的保持迎角恒定的动力补偿系统,经过向仿真系统中加入各种扰动,比较后得出结论为雄鸡尾流和甲板的垂直起伏对着舰的影响最大,故着舰系统要重点抑制这两种扰动从而使着舰过程更加安全可靠.

Influence of Disturbances on Ship-based Aircraft's Landing Process

There are many kinds of disturbances, including 3 airflow disturbance and 6 board disturbance, in the process of landing on the carrier. So it will be very dangerous ff the effect of disturbance can not be rejected and con-trolled. This article focuses on analysing the influences of airflow disturbance and board disturbance through computer simulation in Simulink. The equation is based on the force balance. All of the studies are based on the simple power -expiating system which will keep the incidence angle. After adding different kinds of disturbances into the system, it is concluded that the most dangerous disturbances are cocktail air flow and vertical rolling of the board, which should be restrained emphatically.
