理论近似计算了镁基富燃料推进剂中镁粉与不同氧化剂反应时的爆热、燃烧产物的温度等;测试了不同推进剂体系的燃烧速度;对含四种不同氧化剂的镁基富燃料推进剂的燃烧产物的反应活性进行了研究。研究结果表明:高氯酸铵体系的一次燃烧温度最高,一次燃烧剩余镁粉含量最少;氧化剂为硝酸钾的体系的燃烧温度最低;硝酸钠作为氧化剂的体系的燃速最高,含有高氯酸铵体系的燃速最低;高氯酸钾体系的燃烧产物与水反应的产气总量最多,高氯酸铵体系的燃烧产物与海水反应启动速度最快。

The reaction thermodynamic parameters of magnesium with oxidizers(NaNO3,KNO3,NH4ClO4,KClO4) were calculated.The burning rates were measured.Reactivities of combustion products of the propellants with sea water were studied by a method for collecting gaseous products of H2.The results showed that the first combustion product of NH4ClO4 formulation has got the highest temperature,the lest residual magnesium,and lowest burning rate.The burning rate of NaNO3 system was highest.The reaction of first combustion product of KClO4 system with water had the largest amount of total H2 gas.The first combustion product of NH4ClO4 system had the fastest reaction with sea water.
