Bolting and Go-around Performance Analysis of Carrier-based Aircraft
摘要
Abstract
In view of the complexity and importance of a carrier-based aircraft's landing and recy-cling process,a systematic model during bolting,composed of six-degree-of-freedom mathematic model of the carrier-based aircraft,four-degree-of-freedom model of landing gears and six-degree-of-freedom mathematic model of carrier,was established in the MATLAB-simulink environment,damp-ing function of landing gears and dynamic characteristics of tires being considered.Meanwhile,the air wake and ground effect were numerically simulated in the model.The bolting traj ectory of aircraft was calculated via algorithm for variable step-size Runge-Kuta.The effects of carrier movements,air wake and ground effect on bolting performance of aircraft were illustrated in details.From the calcula-tion results,three important conclusions are obtained:the rolling and yawing movements of carrier threaten the lateral bolting performance,and the lateral displacement of sliding is up to 5 m;air wake antedates the touchdown and induces elevation of longitudinal bolting traj ectory,and the height of air-craft while flying off the carrier is increased by about 14 m when the deck wind is 23.1 m/s(45 kn);ground effect is not beneficial to bolting performance.关键词
