摘要：
In order to investigate the effects of the aluminum particles on the combustion performance of HTPB-based fuels for hybrid propellant, a transparent combustion chamber experimental system was used in this study.HTPB-based fuel containing different particle size (average size is 100nm, 500nm and 50μm) and different mass fraction (5wt%, 10wt% and 15wt%) of aluminum particle respectively were tested and analyzed.The curves of regression rate vs.oxygen mass flux for HTPB-based fuel containing aluminum particles were obtained under the combustion chamber pressure of 1.0MPa.The results showed that the regression rate of HTPB-based fuel containing aluminum particles increased with the increase of the oxygen mass flux.The regression rate of HTPB-based fuel containing 5wt% 500nm aluminum particles was higher than that of HTPB-based fuel containing 5wt% 100nm and 50μm aluminum particles under oxygen flux 250 ~ 375kg/(m2·s).The regression rate of HTPB-based fuel containing 500nm aluminum particles increased with the increase of aluminum particle content. © 2018, Editorial Department of Journal of Propulsion Technology.
