不同条件下复合推进剂点火性能实验

Experimental Study on Ignition Property of Composite Propellants on Different Condition

以促进新型高能复合推进剂工程应用为目的,开展了3种典型复合推进剂的点火特性研究,获得了HTPB推进剂、两种高能推进剂在不同热流密度、环境压强及初始温度条件下的点火规律。结果对比分析表明,在相同的条件下,新型高能推进剂点火最容易,其可靠点燃所需的点火能量最少,同时,其点火安全性更需要得到重视。

The ignition characteristics of three typical composite propellants were studied, in order to promote the new high energy composite propellant＇s application .On different density of heat flow rate, environmental pressure and original temperature conditions, the ignition law of the HTPB propellant, two types of high energy propellant were obtained .The result shows that the new generation high energy propellant can be ignited easily, the ignition energy of it is less than the other two propellants ,its ignition security should be paid more attention.
