Study on the composite modified double base propellant containing3,4-dinitrofurazanfuroxan (DNTF)

The effects of 3,4-dinitrofurazanfuroxan (DNTF) gradually substituting the ingredient RDX in composite modified double base propellant on the energy parameters, combustion properties and mechanical sensitivity were studied. The results show that the theoretical specific impulse, characteristic velocity, flame temperature and average relative molecular mass of combustion products of the composite modified double base propellant all increase because of substituting RDX with DNTF. The friction sensitivity decreases, but the impact sensitivity enhances. When the ingredient RDX of the composite modified double base propellant with plateau effect was replaced with DNTF, the propellant still possesses lower pressure exponent.
