    • PROBLEM TO BE SOLVED: To provide a catalyst decomposition type thruster for a space vehicle, for actualizing high safety and easy assembly even when using HAN (Hydroxylammonium Nitrate) based liquid propellant for one liquid propulsion system. SOLUTION: The catalyst decomposition type thruster for the space vehicle includes a hollow tank for storing the liquid propellant, a combustor for decomposing the liquid propellant and injecting reactive gas, and a propellant valve for controlling the supply of the liquid propellant from the tank to the combustor. The combustor includes a catalyst member having a catalyst to be used for decomposing the liquid propellant, a heating device for heating the catalyst member, and an injector for supplying the liquid propellant to the catalyst member. The catalyst member is a ceramic integrally molded product. COPYRIGHT: (C)2011,JPO&INPIT
