摘　　要：着舰过程中舰尾流影响舰载机高度和速度,造成着舰偏差,甚至会导致复飞。针对舰尾流造成舰载机自动着舰落点精度差的问题,本文首先介绍传统速度恒定动力补偿、迎角恒定动力补偿2种方案,并对迎角恒定动力补偿控制方案进行改进,减小纵向高度通道与速度通道的耦合程度,降低舰尾流对下滑道控制精度的影响。通过数学仿真对比了3种方案抑制舰尾流稳态分量的效果。仿真结果表明,改进的迎角恒定动力补偿方案能够有效抑制舰尾流垂直分量的影响,并能够改善舰尾流水平分量的影响。In the process of carrier landing,the carrier air wake affects the height and speed of carrier aircraft,resulting in landing deviation and even going around.Aiming at the problem of poor accuracy of landing point caused by carrier air wake,this paper firstly introduces the traditional power compensation scheme with constant speed and the traditional power compensation scheme with constant angle of attack,and it improves the power compensator scheme with constant angle of attack to reduce the coupling between longitudinal height channel and speed channel,which can reduce the influence of carrier air wake on the control accuracy of glide path.The effects of three schemes on suppressing the steady component of carrier air wake are compared through numerical simulation.The simulation results show that the improved power compensation scheme with constant angle of attack can effectively suppress the influence of the vertical component of carrier air wake and reduce the influence of the horizontal component of carrier air wake.
