摘　　要：为消除火炮膛内残余燃气的可燃性,采用在膛内添加CO2气瓶的方法,通过燃气组成模型计算得到发射药燃气中可燃气体含量,理论计算得到开闩时能够将膛内残余燃气降至不可燃时所需添加的CO2质量范围。对所得CO2的质量范围结合气瓶和实际应用条件进行理论可行性分析和实验验证,结果表明:装有所得质量范围CO2的气瓶在膛内能够正常开启并放气完全,能有效消除膛内残余燃气可燃性,且消除残余燃气的效果随CO2添加量的增加而越发显著,在实际应用中应以计算所得最大CO2质量作为实际添加量。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 CO= 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 C02 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.
