Abstract
A gas turbine module comprises a frame, a fairing assembly, and a single-piece combination bearing support element. The fairing assembly extends generally axially through the frame between the outer case and the inner hub. The single-piece combination bearing support element is mounted to the frame radially inward of the frame inner hub. The single-piece bearing support element includes a bearing support ring section, a frame mounting ring disposed around an aft end of the bearing support ring section, and a first flow divider ring section contiguous with a forward end of the bearing support ring section.
