Under standard condition (p_e/p_c=７０∶１) ,the energy parameters of the propellant containing 3, 4-dinitrofurazanfuroxan (DNTF) are calculated by CAD system of propellant energy calculation. Results show that the specific impulse of the DNTF monopropellant is 2696.4 N·s·kg^-1 and is similar to that of the CL-20 monopropellant. The theoretical specific impulse and characteristic velocity of propellants including hydroxy-terminated polybutadiene composite propellant, composite modified double base propellant and GAP propellant are increased by DNTF substituting the ingredient RDX or AP. DNTF has no chlorine and its friction sensitivity is much lower than that of RDX, therefore, DNTF introduced into the propellant composition is helpful for the comprehensive performance of the propellant.
