PROBLEM TO BE SOLVED: To provide a propellant tank capable of preventing a flow on vanes, even when acceleration acts on propellant trapped by vanes.SOLUTION: In a propellant tank A arranged in a tank shell 30 with vanes 10 to 13 for collecting and trapping propellant, and a clam 20 fixing the vanes 10 to 13, an acceleration zero portion R, in which an acceleration component along the vanes 10 to 13 is zero when acceleration acts on the vanes 10 to 13, is formed at the vanes 10 to 13. |
