大型飞机迎角限制器设计与飞行品质评估

Design of Limiters for Attack Angle of Large Aircraft and Flying Qualities Evaluation

针对某大型飞机的线性模型设计了纵向电传操纵系统,采用两种不同方法设计了迎角限制器。探讨了大型飞机飞行品质评估的相关问题,同时对迎角限制器对大型飞机飞行品质的影响进行了具体的对比分析。在对应的非线性模型上进行了系统仿真验证,仿真结果证明了所设计迎角限制器的有效性。该研究为我国大型飞机迎角限制器设计及其对飞行品质的影响问题提供了有益的参考。

The longitudinal wired control system for linear model of a large aircraft was designed as well as two different methods were used to design the angle of attack limiter.The issues on evaluation of large aircraft flying qualities were discussed,and the specific and comparative analyses on the impacts of the using of angle of attack limiter to the flying qualities of large aircraft were given.System simulation was taken in the corresponding nonlinear model,and the simulation results show the effectiveness of the design of angle of attack limiter.The research provides a useful reference for the design of angle of attack limiter of our nation＇s large aircraft and its impacts on flying qualities.
