为了研究双座弹射救生系统的轨迹发散特性,以MSC.EASY 5为基础平台进行了求解器设计,并以此为基础对轨迹发散特性进行了仿真计算分析,包括轨迹发散性能评估、轨迹发散对弹射轨迹高度及座椅稳定性的影响.分析结果表明,轨迹发散技术能够有效避免低速弹射时双座间的轨迹干涉,虽然在一定程度上降低了弹射轨迹高度并对座椅稳定性有略微的影响,但是提高了双座弹射救生系统的综合救生性能,研究结果对工程应用具有理论指导意义.
In order to study the trajectory divergence characteristics of the two-seat catapult system, the solver design based on MSC.EASY 5 is carried out. Based on this, the trajectory divergence characteristics are simulated and analyzed, including the trajectory divergence performance evaluation, trajectory divergence pair Trajectory height and seat stability.The analysis results show that the trajectory divergence technique can effectively avoid trajectory interference between two seats when low-speed ejection, though it reduces the ejection trajectory height to a certain extent and slightly affects the seat stability However, the integrated life-saving performance of the two-seat catapult system is improved. The research results are of theoretical significance for engineering application.
