【Abstract】 The application of nitramine propellant is the most facile way to develop high energy and smokeless propellants. A conspicuous aspect of the combustion of the propellant is the insensitivities of burning rate and pressure exponent of ballistic modifiers. Hence, the practical applications of nitramine propellants are limited. For searching the intrinsical courses which result in the difficulty of tailoring the ballistic performance of nitramine propellants, a comprehensive discussion of the fast thermolysis and combustion kinetics of nitramines is reviewed in this paper. Finally, technical approaches to investigate nitramine propellant ballistic modifiers are proposed.更多还原
