摘要
针对采用倾斜箱式发射的导弹在发射离箱之后,喷管处的高温高速燃气会对联装架上其它发射箱的前盖产生较大影响的问题,在进行导弹滑离弹道计算的基础上,应用局部流场区域随导弹同步运动的动网格更新方法,对导弹发射离箱之后的燃气流场进行数值模拟,得到各发射箱前盖表面压力分布及变化曲线;研究结果表明,导弹离箱80ms时燃气射流对箱盖影响最大,位于导弹正上方的发射箱前盖表面压力值最高,且最大压力位于此箱盖下部。
After a missile is launched from inclined launch box, its jet flow will influent the top of other launch box in multi--launcher. Based on calculation of initial trajectory parameters, it uses dynamic mesh update method that zone moving with the missile. The method is used for numerical simulation of the missile launching, pressure distribution of every launching container and pressure curve are obtained. The results show that jet flow influents the launch box most at 80ms, pressure of the launch box above missile is highest, and the maximum pressure is located in it s lower part.
