膨胀波在火炮膛内传播规律的捕捉计算分析

o obtain the rarefaction wave propagation law in the gun, the constitution of complex wave system in the rarefaction wave gun and its propagation characteristics are analyzed according to the emission characteristics of the rarefaction wave gun. Based on the propagation characteristics of the rarefaction wave, the solving method about the propagation velocity of the rarefaction wave in the gun is given by combing with the two-phase flow interior ballistic equations of the rarefaction wave gun. By the capturing calculation about the propagation law of the pressure drop and the comparing with the experimental results, the propagation law of the rarefaction wave in the gun is obtained exactly, and then a feasible method to research the wave effect in the gun is given.
