Space debris causes a severe hazard to the International Space Station. Because of the possibility for the pressure vessels onboard space station to fail catastrophically being impacted these stored energy devices play a central role in determining the survivability of space station when subject to space debris impact. Recent studies of pressure vessel reaction to hypervelocity impact showed that an interaction between traveling debris cloud and gas medium inside the pressure vessel has a dramatic influence on a vessel rear wall deformation and failure. The purpose of this work is to determine the parameters of fragments that travel across the vessel diameter and act on the vessel rear wall, as well as parameters of a shock wave generated in the process of interaction between the debris cloud and gas. For evaluation of debris and gas parameters near the leading edge of the cloud the approach suggested by Nigmatulin is used. According to this approach the adiabatic two-phase flow is considered. The cloud-gas interaction is described by the set of nonlinear hyperbolic partial differential equations. This system is solved numerically by MacCormack method. The model proposed enables us to simulate both the fragments velocities and pressure amplitude of the shock wave. This engineering model and the code developed can be used for both the pressure vessel designing and analysis of its survivability.
