Abstract:

A gas turbine exhaust strut installed in an exhaust case of a gas turbine is disclosed which includes a trailing portion configured with an inner surface for mounting to an inner annular member of the exhaust case and an outer surface for mounting to an outer annular member of the exhaust case, a block attached to the trailing portion, an angled piece attached to the block and configured with a surface on a pressure side of the strut angled with respect to a surface of the trailing portion on the pressure side of the strut, and a transition piece attached to the block and configured with a surface on the pressure side of the strut for smoothing the transition between the height of the block on the pressure side of the strut and the height of the trailing portion on the pressure side of the strut. A method of refurbishing an exhaust strut installed in an exhaust case of gas turbine while retaining at least a portion of the strut in the exhaust case is also disclosed. An exemplary method includes removing a leading edge portion from a trailing portion of the strut, and attaching a replacement leading edge portion to the trailing portion of the strut.
