摘要:

针对速燃火箭发动机大推力短燃时的特点，提出一种满足此要求的新型装药——蜂巢状装药，并对该药型的内弹道特性、燃面规律和力学特点作出了定性和定量分析，对速燃发动机的装药设计有一定的借鉴意义。

Abstract:

According to the property of the large thrust and rapid burning rocket motor,a new type of propellant grain,bee nest propellant grain was put forwardThe quantitative or qualitative analyses were done the internal ballistic properties,burning surface change laws and mechanical charactersThis scheme is referable to the rapid burning rocket motor
