monopropellant




A single liquid, used in a liquid-propellant rocket engine, that serves as both fuel and oxidizer. A monopropellant decomposes into a hot gas when an appropriate catalyst is introduced. The commonest example is hydrazine, often used in spacecraft attitude control jets. See also HAN (hydroxyl ammonium nitrate).
