Centrifugal de-aerator for aircraft engine

A de-aerator for a lubrication system of an aircraft engine, comprising:

• a housing defining an air-oil inlet, an oil outlet, and an air outlet of the de-aerator;
• a rotor received within the housing and rotatable relative to the housing about a central axis, the rotor having blades circumferentially distributed about the central axis and extending at least partially radially relative to the central axis, flow passages extending between the blades, the rotor having a hub circumferentially extending around the central axis and around the blades, the blades extending radially inwardly from the hub towards the central axis, the hub having a peripheral wall oriented radially inwardly and defining a fore opening leading to the flow passages;
• and
• a gap between the housing and a peripheral outer face of the hub of the rotor, the peripheral outer face extending all around the central axis, a portion of the housing received within the fore opening and axially overlapping the peripheral wall of the hub, the gap having a fore gap inlet between the portion of the housing and the peripheral wall of the hub.
