TURBINE EXHAUST CASE MULTI-PIECE FRAMED
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). The multi-piece frame is disposed through and around the fairing to support a bearing load, and comprises an inner ring (104), an outer ring (102) disposed concentrically outward of the inner ring, a plurality of bossed covers (110), and a plurality of radial struts (106). The plurality of bossed covers are bolted to the outer ring at locations circumferentially distributed about the outer diameter of the outer ring. The plurality of radial struts pass through the fairing and are secured via non-radial convectors (112, 114) to the inner ring and the bossed covers.
