The Energy Properties of Fuel-rich Propellants Comprising Furazan Derivatives

Furazan is a kind of novel high energy material and has a good future application in propellants and explosives.This work studies the energy properties of Al/Mg/HTPB/AP fuel-rich propellants comprising furazan derivatives.The results reveal that the specific impulse(I_s) of propellant comprising DAAzF is the largest with the value of 7522.9N·s·kg~-1 at 25% mass fraction,which is about 260N·s·kg~-1 higher than that of propellant comprising CL-20 at the same mass fraction(w).The mean relative molecular mass(M_g) of propellants comprising furazans is about 29,the flame temperature in after-burning chamber(T_c) is about 2200K,and the values of M_g and T_c increase with increasing the mass fraction of furazans.
