摘要：

We report on a simulation of interior flow field in launch box with shock wave-opening technology. A three-dimensional model of the launch box has been established to study the process of shock wave forming and transmitting. The simulation of model was calculated with unsteady standard k - epsilon model. The whole process of numerical simulation includes rocket engine ignition, back lid opening, and the shock wave reflection. Through comparison of contours of pressure and species mass, it is found that the shock wave forming of air not the gas breaks the back lid. Pressure transmission curve obtained in simulation can be a reference for the range of practical friable lid opening pressures.
