摘要
为实现同心发射筒上的系留盖体在燃气作用下打开,讨论盖体分为4片被燃气吹开和盖体整体被燃气吹开2种方案,并对盖体被燃气吹开过程进行模拟分析。计算结果表明,盖体分为4块被燃气吹开速度快,筒内压强降低速度快。因此,盖体分为4块的方案对筒内导弹发射环境更有利。
In order to realize the automatic opening of the reserved cover on concentric canister launcher under the action of exhaust gas,two schemes are discussed:the reserved cover is divided into 4 pieces first and then opened by the exhaust gas and the reserved cover as a whole is opened by the exhaust gas.The opening process of the reserved cover in above two cases is simulated by numerical method.The calculation results show that the reserved cover was opened faster and the pressure inside the concentric canister launcher decreased faster when the reserved cover was divided into 4 pieces.therefore,it is more beneficial for missile launching when the reserved cover is divided into 4 pieces.
