摘要:

研究了某些化合物对丁羟(HTPB)复合固体推进剂燃速压强指数的影响。实验发现,FG是一种降低HTPB推进剂压强指数的高效添加剂。当FG与亚铬酸铜组合使用时,可在提高推进剂燃速的同时大幅度地降低燃速压强指数。文中对FG的作用机理作了初步探讨。

Abstract:

In the present paper, an investigation on effects of some compounds on the pressure exponent of HTPB propellant is presented. The experiment indicates that FG is a good additive for reducing the pressure exponents. When FG and YB are incorporated, they may obviously reduce the pressure exponent of HTPB propellant as well as enhancing the burning rate. In the paper, the catalysis mechanism of FG is preliminarily discussed.
