摘要
为获得含硼推进剂压强指数的主要影响因素,采用捏合机混合物料,真空浇注、恒温固化的方法制备推进剂试样,靶线法测试推进剂(0.5~1.5M Pa)燃速,用u=apn方程求得推进剂的压强指数。实验结果表明,HTPB含量、AP含量及粒度级配、催化剂含量对推进剂的压强指数均有不同程度的影响。HTPB含量减少、AP含量增加、AP重均直径减小、催化剂含量增加,均可提高推进剂的压强指数。
In order to ob propellant samples were constant temperature. T tain the main factors affecting the pressure exponent of boron-based fuel-rich propellant, prepared via mix of the compositions in mixing machine, pouring in vacuum and curing at he burning rate of propellants was determined by strand target method, and the pressure exponent was obtained from u=αp*. The experimental results indicate that the pressure exponent is affected by HTPB content, AP content and gradation and catalyst content to a certain extent. The pressure exponent will increase as HTPB content and AP weight mean diameter decrease, while AP content and catalyst content increase.
