舰载飞机着舰下滑跃升操纵策略仿真与分析

Simulation and analysis about glide path leap control strategy of carrier-based aircraft on landing approach

为了对舰载飞机着舰下滑时的跃升操纵策略进行研究,建立了飞机飞行动力学模型和驾驶员模型。在此基础上,根据"50 ft跃升规范"要求,以F/A-18舰载飞机为例,运用MATLAB/SIMULINK软件,对采取不同操纵策略下的飞机跃升飞行历程进行了仿真分析。结果表明,F/A-18舰载飞机在着舰下滑状态下无法达到"50 ft跃升规范"。此外,飞机在不开启动力补偿的情况下,飞行员需同时操纵油门杆和驾驶杆来实现轨迹跃升。

To research the glide path leap control strategy in carrier landing,establish the flight dynamic model of aircraft and pilot model. On the basis of these two models,taking the F / A-18 aircraft as an example,and according to the requirements about the ＂50ft leap specification＂,the aircraft leap flight histories using different control strategies are simulated and analyzed with the use of MATLAB / SIMULINK software. The result shows that the F / A-18 aircraft couldn ＇t meet the requirements in the ＂50ft leap specification＂on landing approach,and the pilot needs to control the stick and throttle simultaneously to realize the path leap if the APCS（ approach power compensator system） is not turned on.
