摘要： A fuel supply system (1) for a hydrogen-powered aircraft includes: a fuel tank (2) that stores liquefied hydrogen; a pump (5) that discharges the liquefied hydrogen from the fuel tank (2) to supply the liquefied hydrogen to a propulsion device (102); a pressure increasing mechanism (3) that increases a tank internal pressure being a pressure in an inner part of the fuel tank (2); a flow rate controller (71) that controls a flow rate of the liquefied hydrogen to be supplied from the fuel tank (2) to the propulsion device (102); and a pressure controller (73) that controls, on the basis of information which is about the flow rate of the liquefied hydrogen and is input from the flow rate controller (71), the pressure increasing mechanism (3) to adjust the tank internal pressure.
