Abstract:
A turbine exhaust case (28) comprises a fairing (120) defining an airflow path through the turbine exhaust case, and a multi-piece frame (100) disposed through and around the fairing to support a bearing load. The multi-piece frame comprises an inner ring (104), an outer ring (102), and a plurality of strut bosses (106). The outer ring is disposed concentrically outward of the inner ring, and has open bosses (126) at strut locations. The plurality of radial struts pass through the vane fairing, are secured to the inner ring via radial fasteners (108), and are secured via non-radial fasteners (114) to the open boss.
