N2 - The solid fuel regression rate is an important parameter in the design process of the hybrid rocket motor. Additives in the solid fuel may have influence to the fuel regression rate, which will affect the internal ballistics of the motor. Thus it is necessary to carry out experimental investigations for different fuel compositions. A series of firing experiments has been performed on lab-scale hybrid rocket motors with 98% hydrogen peroxide (H202) oxidizer and hydroxyl terminated polybutadiene (HTPB) based fuels in this paper. A fuel regression rate analysis method is put forward to diminish the error caused by start and tailoff stages in a short time firing test. The effects of the metal Mg, Al, aromatic hydrocarbon anthracene (FT) and carbon black (C) on the fuel regression rate are investigated. The fuel regression rate formulas of three kinds of fuel compositions are fitted according to the experimental data. The results show that the metal additives in the HTPB fuel can significantly increase the fuel regression rate. However, the influence of FT on the fuel regression rate is not obvious.
