Abstract

Official abstract text for this publication.

A mid-turbine frame (MTF”) for a jet engine is disclosed and comprises a duct that extends between a high pressure turbine (“HPT”) and a low pressure turbine (“LPT”), the duct comprising a plurality of segments that together form an outer annular structure and an inner annular structure, the inner annular structure situated radially inward of the outer annular structure, and/or a plurality of vanes that extend radially outward from the inner annular structure toward the outer annular structure, each vane comprising a channel. Each segment may be coupled to an adjacent segment by a seal.

First claim

Opening claim text (preview).

What is claimed is: 1 . An apparatus comprising: a radially outward segment portion; a radially inward segment portion; a vane that extends between the radially outward segment portion and the radially inward segment portion. 2 . The apparatus of claim 1 , wherein the vane defines a channel. 3 . The apparatus of claim 1 , wherein the radially outward segment portion comprises a radially inner surface and the radially inward segment portion comprises a radially outer surface. 4 . The apparatus of claim 3 , wherein the radially inner surface and the outer surface define a gas flow path. 5 . The apparatus of claim 4 , wherein the flow path is axial. 6 . The apparatus of claim 2 , wherein a support strut is disposed within the channel. 7 . The apparatus of claim 2 , wherein at least one of an air service line and an oil service line are disposed within the channel. 8 . The apparatus of claim 4 , wherein the gas flow path provides fluid communication a high pressure turbine and a low pressure turbine. 9 . The apparatus of claim 1 , further comprising a perforated structure that is disposed radially outward of the radially outward segment portion. 10 . The apparatus of claim 9 , wherein each of a plurality of perforations in the perforated structure are configured to receive cooling air. 11 . The apparatus of claim 1 , wherein an annular structure is formed from the radially outward segment portion and the radially inward segment portion. 12 . A mid-turbine frame (“MTF”) for a jet engine comprising: a duct that extends between a high pressure turbine (“HPT”) and a low pressure turbine (“LPT”), the duct comprising a plurality of segments that together form an outer annular structure and an inner annular structure, the inner annular structure is situated radially inward of the outer annular structure; and a vane that extend radially outward from the inner annular structure through the outer annular structure. 13 . The MTF of claim 12 , wherein the vane defines a channel. 14 . The MTF of claim 13 , wherein a support strut is disposed within the channel. 15 . The MTF of claim 13 , wherein at least one of an air service line and an oil service line are disposed within the channel.
