| Abstract: | 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. |
