Introduction DNU as a new energetic compound to improve performance of solid propellants

The search for new energetic compounds with high content of energy and desirable properties is one of the major challenges to the chemical industry. In this work, a new energetic compound N,N'-dinitrourea (DNU) will be introduced, which is suitable its application in solid propellants and gas generator systems. A new theoretical model is used to calculate the condensed phase heat of formation of this compound. The specific impulse (Is) of DNU has been computed by complex computer code ISPBKW and compared with those of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro1,3,5,7-tetrazocine (HMX) as two common energetic oxidizers in solid propellants. Furthermore, detonation temperature (T-d) and oxygen balance (O.B) of DNU has been computed and compared with those of RDX and HMX.
