摘要(Abstract)：

为了更为全面的了解单孔发射药的燃烧行为,应用硝基胍单孔发射药进行了中止燃烧实验(半密闭爆发器实验)和密闭爆发器实验,中止燃烧结果显示8 cm长的单孔药有明显侵蚀燃烧现象,密闭爆发器结果显示有侵蚀燃烧的药粒会在燃速系数u_1-Ψ曲线上对应出现一个侵蚀峰。实验结果的综合对比分析结论表明:药粒端面的占比对发射药的渐增性燃烧影响较大;分析密闭爆发器实验的u_1-Ψ曲线可以获知,当药粒达到8 cm长时侵蚀峰可达1个u_1单位的量。
In order to understand the combustion behavior of single-propellant more comprehensively single-perforated NQ propellant was experimented with closed bomb test and interrupted burning test by closed bomb and semi-closed bomb to study its combustion performance. Interrupted burning test show 8 cm length single-perforated NQ propellants have obvious erosion combustion. Closed bomb test show some sharp peaks will occur in the combustion rate coefficient u_1-Ψ curve which the propellant grains have occurred erosion burning. The results, with synthesis and comparative analysis, indicated the end-surface of propellant had great influence on its progressive combustion. It also indicated sharp peak can reach one unit of u_1 when the propellant grain is 8 cm slong by analyzing the u_1-Ψ curve from closed bomb test.
