Abstract: The low pressure compressor (11) and fan (2) together with the intermediate case (10) are removable as a unit from the core engine by removal of the nose cone (62,58) and a stub shaft (40) at the front of the low pressure turbine shaft (38) and at the internal diameter of the fan hub (50) to provide access to attachment bolts (53) at the inner portion of the intermediate case (10) which holds the bearing (34) for the high pressure rotor (35) in position within the intermediate case (10) after assembly of the engine.

Abstract: An oil lubricating and cooling system is positioned in the engine cowl (2) and includes a heat exchanger (84), a compressor (50) for delivering air from air inlets (65) in the surface of the cowl (2) through the heat exchanger (84) and hence to air outlets (104) also in the cowl surface and oil pumps (74,76) also located within the cowl (2) for circulating oil from the sump (42) in the cowl (2) to the heat exchanger (84) to the reduction gear (14,16,20) within the cowl (2) that serve to drive a fan also supported within the cowl (2) and having the blades (32) extending outwardly therefrom. The reduction gear (14,16,20), compressor (50) and pumps (74,76) are all driven from the engine shaft (19), the end of which is located in the cowl (2).

Abstract: A non-rotating flow directing assembly for a gas turbine engine is disclosed. The flow directing assembly is formed of a circumferentially segmented inner case supported by an annular sleeve. The inner case is formed of a plurality of arcuate segments extending axially continuously through the engine. A method of assembling the circumferentially continuous annular sleeve about an axially continuous rotor is also disclosed. In an alternate embodiment the inner case is formed of several pluralities of arcuate segments.
