The purpose of this research is to develop a rated thrust 50kgf class small hybrid rocket engine with paraffin wax filled in radial-hole type fuel. A shortcoming of hybrid rockets is its low thrust. In this study, a new fuel configuration, radial-hole type fuel, has been designed to improve the low thrust of hybrid rockets. Radial-hole type fuel has holes drilled on the outer surface of the fuel in a spiral pattern in the circumferential direction, and paraffin wax is cast into the holes. A single-port fuel which is a conventional fuel configuration is also prepared for comparison. As a result, the following conclusions were obtained; (1) The target thrust of 490N (50kgf) was achieved using the radial-hole type fuel. (2) Thrust increased with the radial-hall type fuel compared to the single-port fuel.
