Abstract
A turbine exhaust case has an inner ring structurally connected to an outer ring via a plurality of struts. An outer flange projects outwardly from the outer case. The outer flange is made of a material different from that of the outer case and includes a ring portion having an inner diameter surface joined to an outer diameter surface of the outer case at a first axial location corresponding to a junction of a leading edge of the plurality of struts and the outer case. The outer flange further includes a tubular portion projecting axially from the ring portion to a second axial location disposed upstream of the struts, and an annular mounting portion projecting outwardly from an outer surface of the tubular portion at the second axial location.
