摘要:

硝胺推进剂是固体推进剂高能化和无烟化的重要途径之一,但所有硝胺推进剂均存在弹道性能难以调节的问题。本文在对近几年硝胺热分解和燃料性能研究结果进行综合分析的基础上,分析丁这类推进剂弹道性能差的本质原因,并进一步提出了硝胺推进剂弹道调节剂研究的可能方向和技术途径。

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.
