摘要
研究了在同心筒垂直发射装置发射过程中导弹周围高温燃气环境对导弹产生的影响。通过同心筒底部导流结构的设计,减少高温燃气的反射,促进高温燃气的排导,从而减少高温燃气对导弹底部的烧蚀。采用数值仿真方法对两种导流方式进行计算模拟和对比。结果表明,采用导流锥型同心筒对导弹发射过程中的压力和热环境有一定效果。
This paper makes a study of the influence of the high temperature jet environment around the missile on the missile during the launching of the missile launcher with a concentric vertical launching device.Through the design of the bottom part of the outside cylinder of the concentric system,the reflection of the high temperature jet can be reduced,thus decreasing the scorch of the high temperature jet point of the missile launching cylinder.The paper also makes use of the numerical value method to give a numerical simulation with the two measures.The result shows that the two measures bring a certain effect in improving the heat and pressure environment during the missile launching.
