摘要

综合考虑空气动力、发动机推力以及摩擦力等因素对舰载机拦阻过程的影响，以拦阻索释放速度作为拦阻过程的控制输入，建立计及拦阻索质量的舰载机偏心拦阻过程的系统状态方程。针对存在边值及过载约束的轨迹优化问题，采用高斯伪谱方法求解理想轨迹，基于GPOPS对飞机存在着舰质量、着舰速度偏差进行算例仿真。仿真结果表明：计及拦阻索质量可以更真实地反映拦阻索输出载荷的变化过程；利用高斯伪谱法可以获得偏心拦阻系统理想的最优轨迹。

Abstract

Considering the impacts of aerodynamic, engine thrust and friction, system state equation of the carrier-based aircraft off-center arresting process choosing the arresting cable velocity as the control variable and taking the arresting cable mass into consideration is established. Ideal trajectory for the trajectory optimization problem with boundary constraints and overload constraints is solved by Gauss Pseudospectral Method. Cases aimed at landing mass or landing velocity deviation are simulation by GPOPS. The results show that dynamic model taking arresting cable mass into consideration can more really reflect the changes of the arresting cable output-load process ; the ideal trajectory can be obtained by Gauss Pseudospectral Method.
