飞行员着舰下滑轨迹跟踪操纵策略研究

Research of pilot control strategy to pursuit flight path in carrier landing

为了比较前面与背面这两种飞行员着舰时所采用的操纵策略,建立了双通道飞行员跟踪控制任务模型。在此基础上,运用SIMILINK软件,仿真了采取两种不同操纵策略下飞机消除轨迹偏差实现轨迹跟踪的飞行历程,得出了两种操纵策略下飞行员模型两个通道的杆偏及飞机相关参数的响应特性。通过分析比较可知,着舰下滑时飞行员采用背面操纵策略更容易进行轨迹跟踪,且当初始轨迹偏差较小时,采用该策略仅控制主通道便可实现轨迹跟踪。

To compare the ＂ frontside＂ control strategy and ＂ backside＂ control strategy in carrier landing,a dual-channel pilot model in pursuit tracking flight is established. On the basis of this,the aircraft response characteristics in carrier landing are simulated by using two different control strategies and the SIMILINK software,and the data about carrier aircraft and dual-channel pilot model are received. Through analysis and comparison of data,it is concluded that the ＂ backside＂ control strategy is easier to use than the ＂ frontside＂ control strategy to pursuit flight path in carrier landing. When the height error is less than a certain value,the pilot can only control the main channel of model to pursuit flight path if he uses the ＂ backside＂ control strategy in carrier landing.
