Simulation and Analysis of Approach Power Compensation for Automatic Landing with Carrier Air Wake

Abstract

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.
