ABSTRACT:
A gas turbine engine (20) comprises a diffuser (24) and a nozzle (26) affixed to a cylindrical housing member (22), a bearing assembly (34) including a support tube (36) affixed at one end (36a) in cantilever fashion to a radially inner portion (26c) of the nozzle, a compressor (28) and a turbine (30) affixed to axially spaced apart ends of a shaft (32) rotatably mounted therebetween in the support tube by antifriction bearings, and an annular combustion chamber (40) disposed between the compressor and turbine and concentric to the shaft. A fuel slinger (38), affixed to the shaft, receives fuel from an air/fuel annulus (96) defined by the support tube and shaft. An air/fuel mixture in the annulus also lubricates the bearings and cools a hub portion (30a) of the turbine. Movement of the mixture through the air/fuel annulus is enhanced by pumps (38c, 102, 104 and 312).
