摘要
燃速是影响固体发动机工作压强诸参数中最活跃的因素,需要在推进剂药柱制造过程中严格加以控制。重点讨论了燃速仪燃速rs、小型试验发动机燃速r127和全尺寸发动机燃速rm之间关系,给出了rm/rs、rm/r127比值与燃速仪燃速rs的相关关系,可以作为预估燃速时参考。
Burning rate is the most active one among the factors having influence on operation pressure of solid rocket motors, so it should be strictly controlled in processing of propellant grain. In this paper,the relationship between strand burning rate r s , small test motor burning rate r (127), and full-sized motor burning rate r m is discussed and expressions between ( r m / r s )?( r m/ r (127)) and strand burning rate r s are given for reference to priori determination of burning rate.
