粉末药型罩射流速度的近似计算方法

Approximate Method of Calculating Jet Velocity of Powder Liners

针对粉末药型罩射流速度低于相应密实材料药型罩的现象 ,首先从理论上分析了药型罩多孔材料特性对爆轰产物作用压力和能量的影响 ;然后提出了把经典的射流速度计算模型用于粉末罩的修正方法 ;最后得到了粉末罩射流速度的近似计算方法 。

The effect of the character of porous material on the working pressure and energy of explosive gas products is analysed. That is directed against the phenomenon of jet velocity between powder liners and dense liners. The revised method of applying the classical model to calculating jet velocity has been provided. An approximate method applied to calculating jet velocity of powder liner is deduced. The method has been proved by experimentation.
