| 摘 要： | 研究了含铅盐、铜盐、炭黑等催化剂的高能无烟改性双基推进剂在中高压下(10～43MPa)的燃烧性能。结果表明,在高压下推进剂的燃速随压强的升高而大幅升高;在25MPa高能无烟改性双基推进剂燃速曲线出现拐点,燃速随压强升高而大幅提高;10～25MPa范围内燃速催化剂对推进剂的燃烧性能有明显影响,NI-Pb/NI-Cu/CB将推进剂燃速提高75.16%(10MPa),而在25～43MPa范围内燃速催化剂对推进剂燃烧性能的影响明显减弱。

| Abstract: | The combustion characteristics of the high-energy smokeless modified double-base propellant (HESMDB) at 10-43 MPa was studied. Results show that the burning rate of HESMDB increases with pressure enhancement. There is an inflexion point in the combustion curve of HESMDB propellant at 25 MPa, and then the burning rate of HESMDB increases rapidly. The effects of combustion catalyst is obvious on HESMDB at 10-25 MPa, and lessened at 25-43 MPa. NI-Pb/NI-Cu/CB enhances the burning rate of HESMDB 75.16% at 10 MPa. |
