N2 - A new hybrid rocket combustion method which can improve the fuel regression rate more than that of conventional method. The new method is named as Multi-Section Swirl Injection Method, which generates swirling flows at some cross-sections in combustion chamber. Combustion experiments with carefully tuned oxygen injections to keep each O/F at optimum value has been successfully conducted. Also throttling experiments, vaporization experiments of liquid oxygen, flight experiments with multi-section swirl injection method have been successfully. The results shows proposed method of vaporization of liquid oxygen is useful and also hybrid rocket engine with Multi-Section Swirl Injection Method can operate with acceleration environment.
