In order to eliminate the flammability hazard of residual propellant gas in the chamber, gas bottle filled with CO2 is equipped. The combustible gas content of the residual propellant gas is calculated by gas constitution model, and then the quantity range of CO2 to make the combustible mixed gas to an incombustible one is obtained through literary calculation. Considering the parameters of gas bottle used and other conditions in practice, the theoretical feasibility analysis and experimental verification of gas bottle filled with mass range of CO2 calculated are carried out, and the results show that the gas bottle with mass range of CO2 obtained can not only be opened and deflate completely, but also effectively eliminate the flammability of the residual gas. Meanwhile, the elimination effect of residual gas becomes more obvious With the increasing of the mass of CO2 added, which means the maximum quantity of CO2 calculated should be applied in practice.
