N2 - This paper proposes a novel star-wheel segmented grain for hybrid rocket. And the influence of the length of the segmented grain on the combustion characteristic of the star-wheel segmented grain hybrid rocket is investigated. Three-dimensional steady numerical simulations are performed on the hybrid rocket that applies hydroxyl-Terminated polybutadiene (HTPB) as fuel and 90% hydrogen peroxide (H-{2} O-{2}) as oxidizer. The temperature distribution, species mass fraction distribution, regression rate distributions, and combustion efficiency are then studied based on simulation results. Simulations indicate that the length of the wheel grain section possesses a positive relationship with the average fuel regression rate. And the addition of the wheel section can improve the combustion efficiency compared with star-star segmented grain. However, the combustion efficiency follows a negative relationship with the wheel grain length, and the combustion efficiency reaches a maximum of 13.48% for the case that possesses the least wheel grain length. This research can provide valuable information on the optimization of hybrid rocket design for better combustion efficiency and higher fuel regression rate.
