APPARATUS AND METHOD FOR DISTRIBUTING BEARING LOAD IN A GAS TURBINE ENGINE

The present disclosure generally relates to monolithic superstructures (200) for supporting a rotating shaft (234) coupled to a rotor (134) relative to a stator. An integral superstructure supports the rotating component. The superstructure includes a bearing portion (230) that contacts the shaft. A stator portion (300), is spaced a critical dimension radially outward, from the rotor. A first annular load transfer portion (236) extends axially forward from the bearing to the stator portion. A second annular load transfer portion (370) extends axially aft from the stator portion to a mounting flange (214). The mounting flange connects the superstructure to a frame. The superstructure maintains a critical dimension between the rotor and the stator as the temperature of the superstructure increases. The rotor may be a compressor impeller in a gas turbine engine and the stator may be an aero component that transfers air into a combustor.
