摘　　要：通过几种燃速调节剂对含奥克托金 (HMX)的丁羟橡胶复合推进剂高、低压的燃烧性能影响实验研究 ,结果表明 ,二茂铁衍生物 (T2 7)能有效调节推进剂燃速和降低高、低压段的压强指数 ,复合燃速调节剂 (T2 7+CB) ,并可消除高压段出现的燃速突变现象。该结果可为单室双推力发动机推进剂燃速设计提供参考。The effect of several burning rate modifiers on combustion properties of HTPB propellant containing nitramine under high and low pressure is investigated.The results show that ferrocene derivant (T27) can effectively modify propellant burning rate and reduce its pressure exponent under high and low pressure.Composite burning rate modifier (T27+CB) can obviously reduce the pressure exponent under low pressure and eliminate the sudden change of burning rate under high pressure.The results can be used as the reference in the design of the propellant burning rate in single chamber dual thrust motor.
