초록

A thermal management system for a gas turbine engine includes a cooling airflow which enters through an air filter portion of a forward cover for filtration of particulate which may result in FOD to a rotational system of the engine. Filtered cooling airflow flows along a rotor shaft over and through a forward bearing, over and through a permanent magnet generator, then over and through an aft bearing to provide thermal management. Commensurate therewith, the cooling airflow atomizes and communicates a lubricant to the bearings. From the aft bearing, the...

What is claimed is: 1. A thermal management system for a gas turbine engine comprising: a forward cover having a filter portion along an axis of rotation of a gas turbine engine; a rotor shaft along said axis of rotation; a forward rotor shaft bearing which rotationally supports said rotor shaft; an aft rotor shaft bearing which rotationally supports said rotor shaft, said forward rotor shaft bearing and said aft rotor shaft bearing in communication with a cooling airflow from said filter portion; and a forward housing defined about said axis of rotatio...
