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.
