摘要
用测定药条燃速的方法 ,在 2 .94～ 8.82MPa压强范围内 ,研究了复合燃速催化剂对丁羟推进剂 (HTPB)压强指数的影响。结果表明 :三氧化二铁、二茂铁衍生物、铜铬催化剂、草酸盐均能降低推进剂的压强指数 ,其中铜铬催化剂降低压强指数效果最好 ,降低幅度达 2 0 %以上 ;草酸盐降低压强指数的效果与其加入量有关 ;一些复合催化剂间存在降低压强指数的叠加效应和择优性。
An investigation about the effects of burning rate bicatalysts on the pressure exponent of HTPB composite solid propellants over the range of 2.94～8.82 MPa was carried out by determining the static burning rate. The results show that in these propellants the pressure exponent was lowered with adding ferric oxide,ferrocene derivant,copper chromium compound,oxalate and bismuthous oxide and a optimal one of these is copper chromium compound which lowered pressure exponent by over 20%,and the capacity of oxalate is related with content. It was found that on lowered the pressure exponent there are a superposition and a preference between some bicatalysts.
