摘要
给出舰载飞机从航空母舰上弹射滑跑起飞的动力学模型、基本解算方法和示例计算结果。考虑了起落架油液减震装置的柔性对起飞滑跑特性的影响,列出了起落架受力的数学模型和飞机纵向动力学方程。根据编制的计算机源程序,以典型的A—6舰载机为算例,给出在整个弹射滑跑起飞过程中的a,x,(?),y和(?)等弹射运动参数的动态反应特性。
Abstract In the paper, a dynamic model, basic solving method and example calculating result of catapult run launch from the carrier deck for a carrier ?based airplane are given. Considering the flexibility effect of hydraulic shock absorber unit of landing gear on launch run characteristics, this paper presents a mathematic model of acting force for landing gear and longitudinal dynamic equations for an airplane. Taking a typical carrier-based airplane as an example, dynamic response characteristics of catapult motion parameters a,x,x,y and y throughout procedure of catapult run launch are given according to the source program.
