| 摘 要： | 通过求解雷诺平均N-S方程，应用嵌套动网格技术结合6-DOF运动方程，成功实现了F/A-18C战机的座舱盖抛放轨迹的数值模拟。同时，分析了座舱盖重心位置的不同对舱盖飞行轨迹和飞行姿态的影响，得出F/A-18C战机座舱盖的重心后移能缩短抛放时间，优化飞行轨迹的结论。

| Abstract: | Aircraft canopy trajectory of fighter F/A-18C was successfully simulated with solving the Reynolds-Averaged Navier-Stokes equations and the 6-DOF motion equations based on the moving grid technique. The effects of trajectory and the states of the canopy caused by different positions of the center of gravity of the canopy were analysed. The conclusion was educed that the retrusive center of gravity could cut the period of the jettison and optimize the flight trajectory. |
