Document Type and Number:
WIPO Patent Application WO/2023/074866
Kind Code:
A1
Abstract:
This fuel supply system (1) for a hydrogen aircraft comprises: a fuel tank (2) that stores liquefied hydrogen; a pump (5) that discharges liquefied hydrogen from the fuel tank (2) and supplies the same to a propulsion device (102); a pressure-increase mechanism (3) that increases tank internal pressure, which is the pressure inside the fuel tank (2); a flow rate controller (71) that controls the flow rate of liquefied hydrogen supplied to the propulsion device (102) from the fuel tank (2); and a pressure controller (73) that controls the pressure-increase mechanism (3) to adjust the tank internal pressure, on the basis of information relating to the flow rate of the liquefied hydrogen input from the flow rate controller (71).
