This fuel system (1A) is provided with: a constant volume pump (2i) and a centrifugal pump (2a) that pressurize and discharge a fuel (N) that is supplied to an aircraft engine (E); a calculation control means (4) that is configured so as to select a constant volume pump use mode in which fuel is pressurized using the constant volume pump or a centrifugal pump use mode in which fuel is pressurized using the centrifugal pump in accordance with the operation state of the engine; and a transmission (2c) that makes it possible to adjust the gear ratio of a rotational speed and that connects the engine and the centrifugal pump, changes the rotational speed of rotational power that is output from the engine, and transmits the result to the centrifugal pump. |
