为明确双基推进剂每单位质量所含能量影响燃速的物理特性量，研究了燃烧波结构。利用氮气加压的套罩式燃烧器燃烧推进剂药条试样，观察了火焰，测量了火焰的温度分布。明确了最终火焰温度对燃速没有直接影响。推进剂含能量即最终火焰温度增加时，暗区的温度增加，与此同时推进剂的燃速增加。这是因为含能量增加时沸腾区的ＮＯ２气体增加，反应加速，在推进剂燃烧表面的温度梯度即热流束增加，促使燃速增加。
In order to clarify the physical characteristics of the burning rate of energy per unit weight of the double-base propellant, the structure of the combustion wave was studied. The propellant drug sample was burned by a nitrogen-pressurized shrouded burner, the flame was observed, and the temperature distribution of the flame was measured. It is clear that the final flame temperature has no direct effect on the burning rate. When the propellant contains energy, ie, the final flame temperature increases, the temperature in the dark zone increases, and at the same time the burning rate of the propellant increases. This is because as the energy content increases, the NO2 gas in the boiling zone increases and the reaction accelerates. As the temperature gradient of the propellant burning surface, ie, the heat flux increases, the combustion rate increases.
