Abstract
A fluid system is provided for a powerplant. This fluid system includes a gear rotor and a deaerator impeller rotor. The gear rotor is rotatable about an axis. The gear rotor includes a web, a toothed rim and a plurality of liquid ports. The web projects radially inward towards the axis from the toothed rim. The toothed rim circumscribes the web. Each of the liquid ports extends axially through the web. The deaerator impeller rotor is mounted to and rotatable with the gear rotor about the axis. The deaerator impeller rotor includes a fluid inlet, a liquid outlet and a gas outlet. The fluid inlet is upstream of and is fluidly coupled to the liquid outlet and the gas outlet. The liquid outlet is axially adjacent the gear rotor and is fluidly coupled to the liquid ports.
