PROBLEM TO BE SOLVED: To provide a propellant tank for a space navigation vehicle and a space navigation vehicle that can inhibit evaporation of a liquid-phase propellant stored in the propellant tank.SOLUTION: A propellant tank such as a fuel tank 6 and an oxidizer tank for a space navigation vehicle, which discharges a propellant such as liquid hydrogen and liquid oxygen stored inside toward a rocket engine with the inside pressurized by a working gas. The propellant tank comprises a tank body 11 storing the propellant of a liquid phase state therein, and a hold and storage part 12 that is provided inside the tank body 11, is disposed leaving a predetermined gap from the inner wall of the tank body 11 and can hold the propellant of the liquid phase state therein when the inside of the tank body 11 is in a minute gravity state or in a zero gravity state.SELECTED DRAWING: Figure 2 |
