Energy Characteristics of Several Propellants With Insensitive and Minimum Signature Properties

The energy characteristics of monopropellants and propellants with insensitive and minimum signature properties containing seven kinds of insensitivity materials, such as N,N′-dinitropiperazine (DNPZ), N-guanylureadinitramide (FOX-12), 1,1-diamino-2,2-dinitroethylene (FOX-7), insensitivity RDX (I-RDX), 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105), nitroguanidine (NQ) and 1,4,5,8-tetranitro-1,4,5,8-tetraazadecalin (TTNZ), are calculated by propellant energy calculation program. The calculation results show that the integrated energy characteristics of monopropellant, composite modified double base propellant and glycidyl azide polymer (GAP) base propellant containing I-RDX, FOX-7 and TTNZ respectively are excellent among seven materials above. The energetic properties of composite modified double base propellant containing I-RDX, FOX-7 and TTNZ, such as specific impulse, characteristic velocity, combustion temperature and heat of explosion at constant volume, increase with the mass fraction of the energetic additives increasing, while the oxygen coefficient and the relative molecular mass of products decrease with the mass fraction of three energetic additives increasing.
