To stabilize phase change in a hydrogen fuel in a fuel supply passage of a hydrogen aircraft.SOLUTION: A hydrogen aircraft comprises: a gas turbine engine including a combustion gas space in which a combustion gas flows and a non-combustion pas space which is adjacent to the combustion gas space in a radial direction of the combustion gs space; a fuel tank which accumulates a hydrogen fuel of liquid phase; a fuel supply passage which connects the fuel tank to the gas turbine engine; at least one heat exchanger located in the combustion gas space; at lest one heat shield movable between a first position projecting from the non-combustion gas space to the combustion gas space so as to cover at least a part of an upstream side of the heat exchanger, and a second position retreated from the combustion gas space to the non-combustion gs space compared to the first position; and an actuator which moves the heat shield between the first position and the second position.SELECTED DRAWING: Figure 2

    【課題】水素航空機の燃料供給路における水素燃料の相変化を安定させる。【解決手段】水素航空機は、燃焼ガスが流れる燃焼ガス空間と、前記燃焼ガス空間の径方向において前記燃焼ガス空間に隣接した非燃焼ガス空間と、を含むガスタービンエンジンと、水素燃料を液相で貯留する燃料タンクと、前記燃料タンクを前記ガスタービンエンジンに接続する燃料供給路と、前記燃料供給路に介在し、前記燃焼ガス空間に配置された少なくとも1つの熱交換器と、前記熱交換器の上流側の少なくとも一部を覆うように前記非燃焼ガス空間から前記燃焼ガス空間に突出した第1位置と、前記第1位置に比べて前記燃焼ガス空間から前記非燃焼ガス空間に退避した第2位置と、の間で移動可能な少なくとも1つの熱シールドと、前記熱シールドを前記第1位置と前記第2位置との間で移動させるアクチュエータと、を備える。【選択図】図2
