OIL SCAVENGE SYSTEM HAVING CHURNING DAMPER FOR GAS TURBINE ENGINES

摘要

An oil scavenge system of a gas turbine engine in accordance with one emb odiment of the present invention, comprises a housing (32) defined about an axis of rotation, the housing (32) confining an air/oil mixture in motion wi thin the housing (32) and defining an oil scavenge area (46) below the axis of rotation. The housing (32) further includes an outlet (48) at a low locat ion of the housing (32). A churning damper (40) is supported within the hous ing (32) and is located in the oil scavenge area (46). The churning damper ( 40) includes at least one plate (42), allowing the air/oil mixture in motion to pass over or through the plate (42) only in a peripheral area of the at least one plate (42) to cause flow energy dissipation.
