用ACP提高固体推进剂的燃速

Improvement of Burning Rate for Solid Propellants by ACP

用快燃物ACP提高改性双基推进剂、AP／HTPB复合推进剂和N-15D推进剂的燃速，取得了非常显著的效果。在HMX和RDX改性双基推进剂配方中加入不同粒度不同含量的ACP，推进剂的燃速均能提高，压强指数基本无变化。在AP基复合推进剂配方中加入ACP，其燃速均有不同程度的提高，而且在7～15MPa的压强范围内，压强指数小于0．45。成功地进行Ф64mm发动机试验，并获得稳定的P-t曲线。N-15D推进剂配方的燃速较低，加入ACP后，燃速也有提高，压强指数稍有增大。结果表明，加入ACP后燃速提高效率分别是：HMX改性双基推进剂配方为40．62％，RDX改性双基推进剂配方为38．00％，复合推进剂配方为37．35％，N-15D推进剂配方为9．90％。

Extraordinary and outstanding effect of improving the burning rate of modified double＇-base propellant, AP based composite propellant and N-15D propellant was achieved with fast-burning energetic material ACP. The burning rates of propellants were all substantially improved but the pressure exponent was not changed basically by incorporating ACP with different particle size and content into HMX- and RDX-based modified double base propellants, The burning rate was greatly increased by incorporating ACP into AP based composite propellant and the pressure exponent was superior to 0.45 at 7-15MPa. It was successfully tested on the Ф564mm motor and p- t curve was obtained. The burning rate of base formulation was quite low when incorporating ACP into N-15D propellant, but the burning rate was still improved and the pressure exponent was increased slightly. The increments of the burning rate were 40.62% for HMX-based modified double propellant,38.00% for RDX-based modified double propellant,37, 35% for AP based composite propellant and 9.90% for N-15D propellant.
