Abstract
A fluid system includes: a hydraulic circuit configured to supply liquid under pressure to a variable pitch mechanism configured to change the pitch angle of a blade provided in a propeller; and a coolant circuit configured to supply liquid for cooling to an electric motor configured to rotate the propeller. Liquid is supplied to the hydraulic circuit and the coolant circuit from a liquid supply unit shared by the hydraulic circuit and the coolant circuit.
