초록 ▼

A gas turbine engine component comprises a frame and a fairing. The frame comprises a monolithic ring-strut-ring structure. The fairing comprises a multi-segment ring-strut-ring structure that is assembled around the frame. A method of assembling the frame and fairing comprises positioning a plurality of shroud segments within a frame and joining the plurality of shroud segments to each other so that the fairing is trapped within the frame. In one embodiment, the fairing comprises a plurality of outer diameter shroud segments, a plurality of inner diameter shroud segments, a plurality of strut segments, and stiffening features connected to the plurality of strut segments to strengthen the fairing.

대표청구항 ▼

1. A turbine exhaust case comprising: a monolithic ring-strut-ring frame comprising: an inner ring;an outer ring; anda plurality of struts connecting the inner ring and the outer ring; anda multi-segment ring-strut-ring fairing assembled around the frame, the multi-segment ring-strut-ring fairing comprising: a plurality of outer diameter shroud segments;a plurality of inner diameter shroud segments; anda plurality of strut segments joined between the outer diameter shroud segments and the inner diameter shroud segments, wherein each of the plurality of strut segments comprises: an outer fairing portion;an inner fairing portion;a strut shell connecting the inner and outer fairing portions; andpads located on the inner and outer fairing portions, wherein the pads extend a partial distance along inner and outer fairing portions to provide local stiffening at leading edge and trailing edge intersections of the strut shell with the inner and outer fairing portions. 2. The turbine exhaust case of claim 1 wherein the segments of the multi-segment fairing are joined in-place around the monolithic frame. 3. The turbine exhaust case of claim 1 wherein: the plurality of outer diameter shroud segments are positioned radially inward of the outer ring; andthe plurality of inner diameter shroud segments are positioned radially outward of the inner ring. 4. The turbine exhaust case of claim 1 and further comprising: an outer stiffening ring connecting the plurality of outer diameter shroud segments and the plurality of strut segments; andan inner stiffening ring connecting the plurality of inner diameter shroud segments and the plurality of strut segments. 5. The turbine exhaust case of claim 1 wherein the monolithic frame is cast as a single piece of metal. 6. The turbine exhaust case of claim 1 wherein each of the segments of the multi-segment fairing comprises a wrought piece of metal. 7. The turbine exhaust case of claim 1, wherein side edges of each pad are obliquely angled such that a pad thickness diminishes near the side edges of each pad. 8. A fairing for a ring-strut-ring frame that defines a flow path, the fairing comprising: a plurality of outer diameter shroud segments;a plurality of inner diameter shroud segments;a plurality of strut segments connecting the outer diameter shroud segments and the inner diameter shroud segments, wherein each of the strut segments comprises: an outer shroud portion;an inner shroud portion; anda strut shell connecting the outer shroud portion and the inner shroud portion; andstiffening features connected to the plurality of strut segments to strengthen the fairing, wherein the stiffening features comprise: an outer ring independent of the ring-strut-ring frame connecting axial surfaces of each of the plurality of outer shroud segments and each of the plurality of strut segments; andan inner ring independent of the ring-strut-ring frame connecting axial surfaces of each of the plurality of inner shroud segments and each of the plurality of strut segments. 9. The fairing of claim 8 wherein: the outer shroud portion and the inner shroud portion comprise rectilinear shapes with recesses in one side; andthe strut shell comprises an elongated member having a shape of the recesses, the strut shell connecting the recesses of the outer shroud portion and the recesses of the inner shroud portion. 10. The fairing of claim 8 wherein the stiffening features further comprise: thickened regions of the outer shroud portions and the inner shroud portions along the strut shell. 11. The fairing of claim 10, wherein the thickened regions extend a partial distance along the inner and outer shroud portions to provide local stiffening at leading edge and trailing edge intersections of the strut shell with the inner and outer shroud portions. 12. The turbine exhaust case of claim 11, wherein side edges of each thickened region are obliquely angled such that a thickness of each thickened region diminishes near the side edges of each thickened region. 13. The fairing of claim 8 wherein the outer ring connects the plurality of outer shroud segments and the outer shroud portions; and wherein the inner ring connects the plurality of inner shroud segments and the inner shroud portions.
