摘要
研究了低燃速HTPB推进剂药柱燃速的控制规律,结果表明:球形高氯酸铵的粒度是决定燃速的主要因素;在粒度相同的情况下,原材料换批等其它工艺因素的差异导致的燃速变化值小于设计公差;经粉碎处理的细粒使高氯酸铵在存放期结块导致燃速缓慢的下降;10L预示燃速略高于500L随机燃速。
The methodolgy to control the
burning rate of Low burning rate HTPB propellant is studied.The results showed that the
burning rate of the propellant is mainly dependent on the particle size of spherical ammonium
perchlorate(AP).The variations in burning rate caused by different bartches of the raw materials
are lower than the design tolerance.The blocking of non spherical AP particles in storgae
decrease the burning rate.The burning rate of the propellant manufactured in 10 L mixer is little
higher than that in 500 L mixer.
