摘　　要：为研究平台含黑索今改性双基推进剂(RDX-CMDB)高压热分解与燃速的相关性,用燃速测试和高压差示扫描量热(PDSC)技术分别研究了两种推进剂在3、6、9、12 MPa下的燃烧性能和热分解。结果表明,PDSC特征量随压强变化规律与RDX-CMDB推进剂出现平台燃烧效应存在联系,综合特征量与RDX-CMDB推进剂燃速线性相关。In order to explore the correlativity of thermal decomposition and burning rate of the platform composite modified double-base propellant(CMDB)containing cyclotrimethylenetrinitramine(RDX),the combustion properties and thermal decomposition performances of two kinds of RDX-CMDB propellants were investigated by burning rate test and pressure differential scanning calorimetry(PDSC).The results show that the characteristic variable of the PDSC is related to the plateau effect of propellants with the change of pressure.The comprehensive characteristic variable is linear correlated to the burning rate.
