To continue fuel supply to an engine even during a blackout without providing an emergency fuel tank for blackout.SOLUTION: A propulsion system 7 of a hydrofoil vessel 100 includes: a fuel tank 74; an engine 72 driven by fuel in the fuel tank 74 for propelling a hull 2 of the hydrofoil vessel 100; a first pump 77 driven by the engine 72; a second flow path 73b with its both ends connected to the first pump 77 in which fuel is circulated by the first pump 77; a flow amount control valve 78 for distributing a part of the fuel in the second flow path 73b to the engine 72; and an ejector 79 provided in the second flow path 73b, having the fuel in the second flow path 73b circulating through as driving fluid, as well as having a suction opening 79c communicated with a fuel tank 74 through a first flow path 73a.SELECTED DRAWING: Figure 5

    【課題】停電時の非常用燃料タンクを設けることなく、停電時でもエンジンへの燃料供給を継続して行う。【解決手段】水中翼船100の推進システム7は、燃料タンク74と、燃料タンク74の燃料によって駆動され、水中翼船100の船体2を推進させるエンジン72と、エンジン72によって駆動される第1ポンプ77と、両端が第1ポンプ77に接続され、第1ポンプ77によって燃料が循環する第2流路73bと、第2流路73bの燃料の一部をエンジン72に分配する流量制御弁78と、第2流路73bに設けられ、第2流路73bの燃料が駆動流体として流通すると共に、吸引口79cが第1流路73aを介して燃料タンク74と連通するエゼクタ79とを備えている。【選択図】図5
