- Abstract:
- The development of a 1 N monopropellant thruster with low freezing point propellant is discussed.The research of catalytic decomposition in mono—propellant rocket engine,including the principle of catalytic decomposition,the analysis of propellant selection,the design of thrust chamber。main problems and resolving metIlods,was introduced.Characteritics of a four—system— propellant with low freezing point were analyzed.The propellant could be catalyzed and decomposed rapidly.The newly designed thrust chamber achieved its stable operation in circumstances of low— temperature.Test results show that the thruster Can start quickly and smoothly with high reliability.
