By using NASA-CEA software, at condition of pc=70 atm, pe=1 atm, and T0=298 K, the energy performances of DNBP-10 in HTPB and gap propellants and CMDB propellants were studied and compared with ADN, AN, HMX and CL-20 in detail. The results show that the energy performance of propellants obviously increased with replacing AP by DNBP-10. For AP/HTPB/Al propellants, the specific impulse increased from 2602.8 N•s/kg to 2616.1 N•s/kg after adding 20% DNBP-10; meanwhile the contribution of DNBP-10 to energy performance is remarkably higher than that of HMX and CL-20.For AP/GAP/Al propellants, the specific impulse increased from 2609.7 N•s/kg to 2650.5 N•s/kg after adding 30% DNBP-10; meanwhile, the contribution of DNBP-10 to energy performance is somewhat lower than that of ADN, HMX and CL-20, and much higher than that of AN. For CMDB propellants, the specific impulse increased from 2532.9 N•s/kg to 2583.7 N•s/kg after adding 30% DNBP-10.However, the contribution of DNBP-10 to energy performance is distinctly lower than that of HMX and CL-20, similar to that of ADN and only higher than that of AN.The above results show that among the three propellants, DNBP-10 can replace AP properly to improve their energy performance, and DNBP-10 is more suitable to use in HTPB propellants and is unsuitable to use in CMDB propellants. © 2020, Editorial Dept. of JSRT.
