摘要
采用最小自由能法计算不同硝酸铵含量发射药燃烧产物中的CO浓度,采用密闭爆发器-气相色谱法静态测试和便携式红外线CO分析仪现场动态测试两种检测方法,研究和测试了硝酸铵对某口径炮射导弹发射药燃气成分中CO浓度的影响。结果表明,加入硝酸铵后,可以提高发射装药的氧平衡,降低燃气中CO的浓度和炮尾CO浓度的峰值。在一定条件下,在发射装药中加入硝酸铵可有效降低炮尾CO有毒排气现象。
The CO concentration in combustion products of propellant with different ammonium nitrate content was calculated by using minimum free energy method.The effects of ammonium nitrate on CO concentration in propellant combustion gas of a gun shooting guided missile propelling charge are investigated by means of closed-bomb-gas chromatography used in lab scale investigation and on-line IR used in gun operation.Tests results show that adding ammonium nitrate in gun propellant can increase the oxygen balance of propelling charge,also can reduce CO concentration in combustion gas of propelling charge and can reduce CO peak concentration.In particular condition,adding ammonium nitrate in gun propellant can effectively reduce the phenomena of exhausting carbon monoxide poisonous gas.
