The engine comprises a turbine casing 10, an air intake housing 11, intake support structure 15, an exhaust system 30 and a fluid passage formed through the housing for fluidly connecting the air intake to the exhaust outlet. The stubs 19,21 of an air compressor 18 are rotatably mounted by bearing assemblies 20,22 to support housing 12 while the forward end of the air compressor 18 is open to the air intake 14. Turbine stages 36,38 are positioned within the exhaust passageway 30 and are secured to the rear stub 21 of the compressor 18 by a cone headed turbine bolt 48 so that the bearing assemblies 20, 22 which rotatably mount the compressor stubs 19, 21 to the housing 12 also rotatably mount the turbine stages 36,38 to the housing. The turbine stages 36,38 are located to each other and the compressor by labyrinth sleeves 60,61. The cantilevered mounting of the turbine allows the bearing assemblies 20,22 to be located in a relatively cool zone of the engine thus preventing rapid deterioration of lubricant. <IMAGE> |
