摘要/Abstract

摘要： 通过超级及市售ＣａＣＯ３在低含量下（≤１％）对丁羟推进剂燃烧及工艺性能影响的研究，发现两种ＣａＣＯ３均可提高推进剂的燃速，且随超细ＣａＣＯ３含量增加，推进剂压强指数降低，与市售ＣａＣＯ３相比，超细ＣａＣＯ３的催化效率较高，但同时也使推进剂的工艺性能变差。

Abstract: The effect on combustion performance and technological property was studied with CaCO 3 Ultrafine Particles (UFP) and normal CaCO 3 contained in AP/Al/HTPB propellant.The result shows that CaCO 3 may increase the burning rate of the propellant when it’s content is not more than 1%,and the pressure exponent of propellant decrease with the content of CaCO 3 UFP increasing.Compared with the normal CaCO 3,CaCO 3 UFP has higher catalytic efficiency while it make the technological property of the propellant poor
