Composition, characterization and performance studies of hybrid rocket motor doped with metallic additives and high entropy alloy

The poor combustion efficiency and low regression rate of the Hybrid Rocket Motor (HRM) limit its use in propulsion systems. Therefore, a thorough examination of the use of high-energy additives such as metals and alloys were carried out to improve the ...

Investigation of Non-Conventional Bio-Derived Fuels for Hybrid Rocket Motors

, 2007
Non-conventional bio-derived fuels have been evaluated for use in hybrid rocket motors. Tests were conducted at combustion pressures in the range of 100 – 220 psig and thrust levels of 40 – 170 newtons.
