| 摘 要： | 通过对NEPE推进剂燃烧表面的热平衡分析，指出了影响推进剂燃速的3个因素：“嘶嘶”区（fizz）的温度梯度、凝聚相反应热和燃面温度，提高了降低NEPE推进剂燃速的可能途径，研究了某些燃速降速剂的作用及其对推进剂能量的影响。用实验证明了降低燃速几个途径的可行性。

| Abstract: | Three factors,including temperature profile of fizz zone,heat of reaction of condensed phase and temperature of burning surface have been found to affect the burning rate of NEPE propellant by the light of analysis of the heat balance on the burning surface.The possible methods to decrease burning rate are presented,the action of burning rate depressants and the effect on energy of propellant are researched.The results show that the approach for decreasing the burning rate of propellant is feasible. |
