Abstract
AbstractHypergolic fuel has unique importance in missiles and satellite launch vehicles. Hydrazine and its derivatives (Monomethyl hydrazine, MMH and Unsymmetrical Dimethyl Hydrazine, UDMH) are the continuous choices of fuel in bipropellant though it is carcinogenic and toxic. Development of new, green and cost‐effective fuel blends based on trust‐worthy, ionic liquid and biofuel in different volume proportion have been reported. The blends exhibit reasonably good stability (chemical and thermal), low viscosity (η < 15 mPa⋅s), high density (ρ > 1 g/cm3), low ignition delay and high performance in comparison with UDMH ‐ a proven liquid fuel presently being used as promising fuels for liquid rocket application. The reported blends appear to be a technologically promising, eco‐friendly and affordable fuel blend to replace currently used liquid toxic fuels.
