Energy Characteristics of Solid Propellant Containing 1-Amino-1,2,3-Triazolium Nitrate(ATZ-NO_3)

Under the standard condition(Pc/Pe=70∶1),the energy characteristic parameters of the solid propellant containing 1-amino-1,2,3-triazolium nitrate(ATZ-NO3)were calculated by GJB/84-96 and CAD system of propellant energy calculation using the minimum free energy method.The result shows that specific impulse of ATZ-NO3 monopropellant is 2 413.96N·s·kg-1,which is much higher than that of AP monopropellant and similar to that of RDX and HMX monopropellant.Specific impulse and characteristic velocity of HTPB propellant decrease with ATZ-NO3 substituting the ingredient AP or RDX.But for GAP propellant,specific impulse and characteristic velocity were characterized by parabolas with the increasing of ATZ-NO3 content by substituting the ingredient AP.The maximum specific impulse can reach 2608.50N·s·kg-1and there exists optimum content ratio of solid fillers.Meanwhile ATZ-NO3 has no chlorine,therefore,ATZ-NO3 introduced into propellant composition is helpful for the comprehensive performance of GAP propellant.
