ACP对无烟改性双基推进剂能量和燃烧性能的影响

The Effect of ACP on the Energy and Combustion Performance of Smokeless Modified Double-base Propellant

含ACP的无烟改性双基推进剂能量特性理论计算表明,ACP对推进剂的能量影响较小。研究了不同工艺对含ACP无烟改性双基推进剂燃烧性能的影响。实验结果表明,ACP对压伸工艺制备的推进剂燃速没有显著提高,但能大幅度地提高浇铸无烟改性双基推进剂的燃速。分析了ACP提高无烟改性双基推进剂燃速的作用机理,认为ACP可增加燃烧表面积和热量向燃烧表面积的反馈,使推进剂的燃速大增。

The theoretical calculation results of energy characteristics for smokeless modified double-base propellant with ACP show that ACP can decrease the energy of the propellant. The effect of different technology including casting and extrution on the combustion performance of smokeless modified double-base propellant with ACP was studied. The results show that ACP can increase the burning rate of the casting propellant, while ACP can not increase the burning rate of the extrusion propellant, obviously. The mechanism of increasing the burning rate of the propellant by ACP was experimentally analyzed. It is considered that the combustion surface and the heat feedback of the propellant are increased by addition of ACP,leading that the increasing of burning rate of the propellant.
