针对保持迎角恒定的动力补偿器(APC)能否兼顾保持舰载机进场空速的问题,结合H-dot指令自动着舰系统(ACLS)的工作特点,对舰载机自动着舰过程中最常见的3种指令响应情况进行了理论分析。基于H-dot指令ACLS的控制器基本构型,通过仿真研究了保持迎角恒定APC中各类指令信号对ACLS纵向控制性能的影响。仿真结果表明:不同APC指令信号对ACLS纵向控制的影响程度不同;只要稳态飞行时舰载机航迹角不变,保持迎角恒定的APC就能维持进场舰载机的空速恒定。
Aiming at the problem of keeping APC at a constant angle of attack (AOA) and keeping the airspeed entering the carrier-borne aircraft, combined with the operating characteristics of the H-dot Command Automatic Launch System (ACLS) In the three most common instruction response to a theoretical analysis. Based on the controller basic configuration of H-dot ACLS, the influence of various kinds of command signals on ACLS longitudinal control performance is studied by simulation. The simulation results show that the influence of different APC command signals on the longitudinal control of ACLS is different. As long as the heading angle of carrier aircraft remains unchanged during steady state flight, the APC maintaining a constant angle of attack can maintain the airspeed constant.
