Hydrogen Peroxide Based Propulsion System for Micro Air Vehicle Applications
Abstract
The miniaturisation of sensors and weapon system will enable the development of micro air vehicles (MAVs) for use in military and surveillance operations, such as signal jamming and intelligence gathering. However, the propulsion systems for MAVs will need to have a range of engine characteristics to satisfy operating requirements. The Propulsion Department of DERA proposed a hydrogen peroxide (H2O2), hybrid rocket/turbine engine for micro air vehicle propulsion. A feasibility study was carried out on the proposed engine and compared against parameters set out in a preliminary specification. The study shows that a bipropellant system with on-board oxygen gives the best flight endurance. The engine configuration will consist of a convergent/divergent nozzle and a ducted fan. This engine can largely meet the physical requirements. It can also meet the indoor and urban reconnaissance requirement of 1-hour flight endurance. The H2O2 engine compares favorably with a rival engine (micro gas turbine). However, the hydrogen peroxide system has an important advantage that it is an established technology and carries considerably less technical risk.
