Abstract
An oil scavenging system and method suitable for use in a gas turbine engine having a bearing housing. The bearing housing provides for arcuate slots within the housing and a plurality of peripherally arranged apertures disposed for cooperation with the arcuate slots. During rotation of the bearing and shaft, the rotational momentum induces rotation of the oil which distributes the oil to the peripheral circumference of the housing for eventual passage through the slots and apertures. The arrangement maximizes the use of the circumferential space of the bearing for efficient oil distribution.
