Aircraft carrier landing process simulation based on extremely short-term prediction of ship motion

Abstract

[Objectives] Aircraft carrier landing is the key part of the whole flight process of carrier-based aircraft, and the technology design is difficult due to ship motion.[Methods] Based on the extremely short-term prediction method,this paper develops an aircraft landing simulation. First,based on the traditional extremely short-term prediction of ship motion,a method is proposed for determining the best prediction method by matching the waveform of the predicted signal combined with affine transformation. Next,an aircraft carrier landing guidance system is built on the basis of light beam guidance,and three landing end point errors for measuring the landing guidance system are presented. Finally,the aircraft carrier landing process is simulated,the errors between ideal approach path and tracking error of landing aircraft analyzed,and landing end point errors obtained.[Results] It can be seen from the simulation results that the landing points of aircraft are relatively concentrated,with most located within the scope of ideal landing points. The end point errors satisfy the requirements of landing guidance system standards. [Conclusions] The simulation results in this paper offer great reference value for the study of aircraft carrier landing.
