To stably operate a hydrogen fuel feed system of an aircraft.SOLUTION: A hydrogen fuel feed system includes: a fuel tank storing hydrogen fuel; a fuel feed path connecting the fuel tank to an engine of an aircraft; a pressure pump that is provided in the fuel feed path and pressurizes the hydrogen fuel toward the engine; a main control valve provided between the pressure pump and the engine in the fuel feed path; a discharge flow path connected to a portion between the pressure pump and the main control valve in the fuel feed path; a sub-control valve provided in the discharge flow path; an outlet pressure sensor that detects an outlet pressure of the pressure pump; and a processing circuit configured to control the pressure pump, the main control valve, and the sub-control valve. The processing circuit is configured to control the sub-control valve so as to increase an aperture of the sub-control valve when the outlet pressure detected by the outlet pressure sensor exceeds a predetermined threshold.SELECTED DRAWING: Figure 2

    【課題】航空機の水素燃料供給システムを安定して動作させる。【解決手段】水素燃料供給システムは、水素燃料を貯留する燃料タンクと、前記燃料タンクを航空機のエンジンに接続する燃料供給路と、前記燃料供給路に設けられ、前記水素燃料を前記エンジンに向けて加圧する加圧ポンプと、前記燃料供給路において前記加圧ポンプと前記エンジンとの間に設けられた主制御弁と、前記燃料供給路において前記加圧ポンプと前記主制御弁との間の部分に接続された排出流路と、前記排出流路に設けられた副制御弁と、前記加圧ポンプの出口圧力を検出する出口圧力センサと、前記加圧ポンプ、前記主制御弁及び前記副制御弁を制御するように構成された処理回路と、を備える。前記処理回路は、前記出口圧力センサによって検出された出口圧力が、予め定められた閾値を超えると、前記副制御弁の開度を増やすように前記副制御弁を制御するように構成されている。【選択図】図2
