Abstract
A hybrid bearing system for gas turbine engines is disclosed. The hybrid bearing system comprises ball/roller bearings and air bearings. For horizontal applications, compressed air injected into the air bearing provides a lift force such that enables the rotating shaft for the turbine to float freely. The compressed air is also employed to cool the ball/roller bearings. Hence, given the reduced friction on the ball/roller bearings due to the free-floating shaft, as well as the air cooling of the ball/roller bearings, typical lubrication systems are not necessary. For vertical applications, the compressed air provides cooling to the ball/roller bearings which renders the need for conventional lubrication systems unnecessary.
