Increasing added quantity of ethyne carbon in the propellants can enhance the burning rate and lower the pressure exponent of the propellant in the pressure range of 3~ 20MPa. 增加乙炔碳黑含量可使推进剂在3~20MPa压力范围内的燃速提高,压力指数降低。
The carbon fiber improves the conduction of heat exchange, increases intensity of propellant, enhances the burning rate of propellant and prevents propellant from cracking. 碳纤维改善了推进剂燃烧表面的导热,增加了推进剂基体强度,可提高其燃速,预防复合推进剂的破裂。
