Abstract

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 5-20MPa 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 pressure range from 5MPa to 20MPa.
