Abstract
Hybrid rockets have been studied for space transportation. Hybrid rockets are regarded as more suitable for manned space transportation than solid fuel rockets or liquid fuel rockets because hybrid rockets are essentially safe. This study examines another means of using hybrid rockets. Our suggestion is an air-breathing type hybrid rocket booster for small aircraft. After conducting theoretical calculations, we identified the need for an axial-flow compressor for air inhalation. The use of a metalized solid fuel is expected to increase the hybrid rocket propulsion performance. Additionally, when a hybrid rocket booster is designed with general versatility, it can be installed in various aircraft. The design offering general versatility is expected to lower operating costs. And, when using cartridge type solid fuel, the hybrid rocket engine can be reused. This study yielded some knowledge related to hybrid rocket boosters.
