Turbofan engine bearing support

摘要

A turbofan engine (20) comprises an engine case (22). A gaspath extends through the engine case (22). A fan (42) has a circumferential array of fan blades (100). A fan case (40) encircles the fan blades (100) radially outboard of the engine case (22). A plurality of fan case vanes (44) extend outward from the engine case (22) to the fan case (40). A front frame assembly (172) includes a plurality of vanes (173) extending radially across the gaspath. A transmission (46) couples a shaft (25) to a fan shaft (132) to drive the fan (42). A bearing assembly (176) couples the shaft (25) to the front frame assembly (172). A bearing support (454) extends aftward and radially inward from the front frame assembly (172) to the bearing assembly (176).
