RÉSUMÉ

Inert gas was added to a gun-launched missile chamber to eliminate the flammability hazard of residual propellant gases. The combustible gas contents of three types of propellants were calculated using a gas constitution model. Based upon this information, the flammability of the gases was analyzed. Considering CO2 as a fully reacted gas and assuming gas composition does not change during the mixing process of CO2 with propellant product gases, the quantities of CO2 required to change the combustible gas mixture to a nonflammable one were obtained. This information helps to solve practical engineering problems.
