Effect investigation of debris cloud hypervelocity impact perforation on pressurized module interior pressure and temperature

In order to know the influence extent and change rule of module interior atmosphere pressure and temperature created by debris cloud impact module wall. Based on the theory of plane shock wave and thermodynamic, the model that studies the effect of debris cloud hypervelocity impact perforation on pressurized module interior atmosphere pressure and temperature was built. The results obtained by using the model were consistent with experimental results. The calculation results show that the change tendency of module interior atmosphere pressure and temperature has similarity; module interior atmosphere pressure and temperature generate great change in only certain range from perforation location in perforation instant; the larger the impact velocity of debris cloud, the larger the changes of module interior atmosphere pressure and temperature.
