摘　　要：通过理论计算和初步实验 ,证实少烟高固体含量丁羟推进剂是实用的。研究表明 ,铝粉含量对 I°sp、燃气中 Al2 O3 含量、ρ有显著影响 ,降低铝粉含量 ,比冲大幅度下降 ;RDX代替部分 AP,燃气中 HCl、H2 O含量降低 ,但 ( CO+H2 )含量增加 ,增加了燃气的二次火焰 ,低铝粉配方中 ,RDX不能提高比冲 ;增加固体含量 ,能明显提高比冲和密度 ,是提高能量特性的有效途径 ;提高压强 ,比冲增加 ,燃气中 H2 O%和 CO+H2 含量减少 ,有利降低烟雾。固体含量A reduced smoke propellant with high solid content was proved to be practical by theoretical calculation and experiments.The results show that the content of Al has significant effect on I ° sp ,Al 2O 3 content and density.The specific impulse decreases rapidly with the decrease of Al content.Partially replacing AP with RDX makes a decrement of HCl and H 2O content,but an increment of (CO+H 2)content and secondary flame.RDX has little effect on specific impulse in the propellant with low Al content.An effective approach to improve energy is to increase solid content becase I ° sp and density can be incresed significantly With the improvement of pressure, I ° sp increases,H 2O and (CO+H 2)content in plume decreases,thus it is beneficial to reduce smoke.The propellant with 89% solid content has better property.
