大型飞机迎角限制方法研究

Method Study of AOA Limiter for Large Transport Category Airplanes

研究了典型运输类飞机的迎角保护方案,并且探讨了它的不同特点,在此基础上提出一种采用积分控制来减小静态误差的大型飞机迎角保护方案,并且深入的研究了采用最大值切换逻辑和加权过渡逻辑两种不同方法来进行迎角与过载限制器切换的不同特点,系统仿真证明结论正确。为我国未来大型飞机采用何种迎角保护方法提供了部分理论依据。

The different methods of AOA limiter for several classical large transport category airplanes were studied and their different characteristics were explored.Based on these,a new method of AOA limiter for large transporters which minimizes the steady tolerance by using integer controller were suggested.Furthermore,the different influence to plane's response by using MAX logic switcher and smooth transition switcher was analyzed.The conclusion were proved by computation and simulations finally.
