Abstract: The process and the pressure of the exhaust gas flowing in the outer space simulated test cabin was analyzed and calculated Based on the one dimensional isentropic flow theory with effects of shock waves, two possible processes of the gas discharged by the tested engine in the outer space simulated test cabin were analyzed, and the pressure was calculated Then,the curves for the pressure change of gas flowing was proposed The results form a base for the design of outer space simulated test cabin and for the vacuum system

Key words: Altitude simulation test;Flow characteristis;Numerical calculation
