Abstract
The described air-oil separation apparatus for an oil system of a gas turbine engine includes an oil tank having an oil impingement surface disposed on a tank bottom proximate an oil tank outlet and a centrifugal air-oil separator mounted within the oil tank. The centrifugal air-oil separator has an oil outlet that feeds an impingement nozzle having an outlet oriented, in operation, to eject an oil jet from the centrifugal air-oil separator to impinge the oil impingement surface at an intersection point spaced apart from the oil tank outlet.
