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

    【課題】推進薬タンクに溜められる液相の推進薬の蒸発を抑制することができる宇宙航行体用の推進薬タンク及び宇宙航行体を提供することを課題とする。【解決手段】作動ガスにより内部が加圧されることで、内部に溜められる液体水素及び液体酸素等の推進薬を、ロケットエンジンへ向けて排出する宇宙航行体用の燃料タンク6及び酸化剤タンク等の推進薬タンクであって、液相状態の推進薬を、内部に溜めるタンク本体11と、タンク本体11の内部に設けられ、タンク本体11の内壁と所定の隙間を空けて配置されると共に、タンク本体11の内部が微小重力状態または無重力状態において、液相状態の推進薬を内部に保持可能な保持収容部12と、を備える。【選択図】図2
