同心发射筒内燃气流对密封盖冲击的数值仿真

The Numeral Simulation of Impact of Combustion-gas Stream in the Concentric Canister Launcher (CCL) on Hermetic Lid

主要研究同心发射筒的燃气开盖问题。根据实际情况建立了等效三维模型,用数值方法对筒内三维流场进行了计算,并通过分析计算结果得到了相应的结论。

This paper analyzes on the problem of uncapping lid with gas in CCL, establishes the equivalent 3D module according to the actual situation, calculates the 3D flow field in the canister by using the numeral method, and obtains the corresponding conclusions through analyzing the calculative resuh.
