摘　　要：设计了以CL-20、HMX、RDX及其混合物为氧化剂的XLDB推进剂,研究了其燃烧性能。结果表明,用CL-20替代XLDB推进剂中的HMX、RDX可大幅提高其燃速,压强指数略有提高。5～20MPa的压强指数为0.48。用CL-20替代50%(质量分数)HMX、RDX后,推进剂的燃速变化趋势不同。在低于12MPa时,CL-20/HMX-XLDB推进剂的燃速低于HMX-XLDB推进剂,且在5～20MPa范围内压强指数较高。Formulas of cross-linking modified double-base propellant with CL-20,HMX,RDX and their mixture as oxidizer were designed.Their combustion properties were studied.The results show that the burning rate of propellant with CL-20 was obviously increased with slightly higher pressure exponent.The pressure exponent over the pressure range of 5-20 MPa is only 0.48.The trends of combustion properties for CL-20/HMX-XLDB and CL-20/RDX-XLDB propellant after the substitution of CL-20 for 50%（mass fraction） HMX or RDX are different.The burning rate of CL-20/HMX-XLDB propellant is lower than that of HMX-XLDB propellant at the pressure of 12MPa.The pressure exponent of CL-20/HMX-XLDB propollant is higher than that of HMX-XLDB propollont over the presure range from 5 MPa to 20 MPa.
