采用非结构网格、有限体积方法,利用准定常假设,对两种飞机在不同状态下与导弹的分离进行了数值模拟,并将计算结果和试验进行了比较。数值模拟的结果和试验结果表明,对于升力系数和俯仰力矩系数随攻角的变化、导弹轨迹随时间的变化两者吻合较好。
The unstructured grid and finite volume method are used to simulate the separation of the two kinds of missiles from the missiles under different states by using the quasi-stationary assumption. The calculated results are compared with the experimental ones. The results of numerical simulation and experimental results show that the change of missile trajectory with time is in good agreement with the change of attack angle of lift coefficient and pitch moment coefficient.
