Definitions
- This disclosure relates to a hydrogen fuel supply system for an aircraft equipped with an engine.
- Patent Document 1 discloses a hydrogen fuel supply system for aircraft.
- liquid hydrogen in a fuel tank is pressurized by a pump and heated by a heat exchanger, and then supplied to the engine in the gas phase or supercritical phase.
- Hydrogen fuel can be put into the supercritical phase by pressurizing it above its critical pressure and then heating it to a temperature above its critical temperature. To change hydrogen fuel into the supercritical phase using this method, it is first necessary to pressurize the hydrogen fuel above its critical pressure.
- One aspect of the present disclosure aims to stabilize the operation of an engine that uses hydrogen fuel in the supercritical phase.
- the pressure of the hydrogen fuel can be measured by a sensor downstream of the pressure pump. This makes it possible to control the operation of the pressure pump according to the pressure of the hydrogen fuel, thereby stabilizing the operation of an engine that uses hydrogen fuel in the supercritical phase.
- FIG. 1 is a plan view of an aircraft equipped with a hydrogen fuel supply system according to a first embodiment.
- FIG. 2 is a phase diagram showing the relationship between the phase of hydrogen and temperature-pressure.
- FIG. 3 is a block diagram of the hydrogen fuel supply system of FIG.
- FIG. 4 is a block diagram of a hydrogen fuel supply system according to the second embodiment.
- an aircraft refers to a device capable of moving through the air, such as a fixed-wing aircraft, a rotorcraft, or an unmanned flying object.
- FIG. 1 is a plan view of an aircraft 1 equipped with a hydrogen fuel supply system 10 according to a first embodiment.
- the aircraft 1 includes, for example, a fuselage 2, a main wing 3, a horizontal stabilizer 4, a vertical stabilizer 5, and a gas turbine engine 6.
- the fuselage 2 extends in the longitudinal direction of the aircraft 1, and defines an occupant space therein.
- the main wing 3 is connected to a middle portion of the fuselage 2 in the longitudinal direction, and protrudes from the fuselage 2 in the lateral direction of the aircraft 1.
- the horizontal stabilizer 4 protrudes from the rear of the fuselage 2 in the lateral direction of the aircraft 1.
- the vertical stabilizer 5 protrudes upward from the rear of the fuselage 2.
- the gas turbine engine 6 is connected to a pair of main wings 3.
- the hydrogen fuel supply system 10 is mounted on the fuselage 2, the main wing 3, and the gas turbine engine 6.
- the fuel tank 21 is disposed in the fuselage 2, but may be disposed in the main wing 3. That is, all or a part of the fuel tank 21 is disposed in the fuselage 2 or the main wing 3.
- Figure 2 is a phase diagram showing the relationship between hydrogen phases and temperature-pressure.
- the solid phase and gas phase are separated by the sublimation line L1
- the solid phase and liquid phase are separated by the melting line L2
- the liquid phase and gas phase are separated by the boiling line L3.
- the intersection R of the sublimation line L1, melting line L2, and boiling line L3 is called the triple point.

- the point of the critical pressure Pc and the critical temperature Tc is called the critical point Q.
- the critical pressure Pc is about 1.3 MPa
- the critical temperature Tc is about -240°C.
- the hydrogen fuel in the phase diagram of FIG. 2, the hydrogen fuel is prevented from changing from the liquid phase to the gas phase by crossing the boiling line L3. That is, while the hydrogen fuel is in the liquid phase, the hydrogen fuel is pressurized so that the pressure of the hydrogen fuel is equal to or higher than the critical pressure Pc, and then when the hydrogen fuel is heated and reaches a temperature equal to or higher than the critical temperature Tc, the hydrogen fuel transitions from the liquid phase to the supercritical phase.
- the liquid phase hydrogen fuel flowing from the fuel tank 21 to the fuel supply line 22 is pressurized by the pressure pump 26 to a pressure equal to or higher than the critical pressure Pc.
- the hydrogen fuel flowing from the pressure pump 26 toward the gas turbine engine 6 is heated by the heat exchanger 28 or the like and reaches a temperature equal to or higher than the critical temperature Tc, the hydrogen fuel transitions from the liquid phase to the supercritical phase. This prevents the hydrogen fuel in the fuel supply line 22 from boiling from the liquid phase to the gas phase.
