An annular mount for a gas turbine engine includes a first flange and a second flange. The first flange has an arcuate shape, and the second flange extends from the first flange. The second flange has an interface surface along at least one side and has a plurality of mounting apertures extending therethrough. The channels extend along a length of the interface surface from a first edge to a second edge.

1. An annular mount for a gas turbine engine, comprising: a first flange having an arcuate shape; anda second flange extending from the first flange and having an interface surface along at least one side of the second flange, wherein the second flange has a plurality of mounting apertures extending therethrough and a plurality of channels that extend along a length of the interface surface from a first edge to a radially outermost edge of the second flange, wherein a pair of adjacent channels has one of the plurality of mounting apertures disposed therebetween, and wherein the second flange has impingement holes that extend through the second flange, and wherein at least one of the channels communicate with one or more impingement holes. 2. The annular mount of claim 1, further comprising a shoulder that extends axially from the second flange, wherein the interface surface extends both radially along the second flange and axially along the shoulder, and wherein each of the channels have an axially extending portion and a radially extending portion. 3. The annular mount of claim 1, further comprising a first casing with a mounting surface that is connected to the second flange, wherein the channels allow for the passage of a secondary gas flow between the annular mount and the mounting surface from a first cavity to a second cavity, and wherein a radially inner surface of the first casing at least partially defines the first cavity. 4. The annular mount of claim 1, wherein the annular mount comprises a mount ring. 5. The annular mount of claim 1, further comprising: a first casing adapted with the annular mount on an end thereof; anda second casing mounted to the first casing by the annular mount, wherein the channels along the interface surface allow for the passage of a secondary gas flow between a first cavity defined at least partially by a radially inner surface of the first casing and a second cavity defined at least partially by the second casing. 6. The annular mount of claim 5, wherein the channels extend both radially and laterally with respect to a centerline axis of the gas turbine engine. 7. The annular mount of claim 6, wherein each channel crosses over an adjacent channel as each channel extends radially outward. 8. An assembly for a gas turbine engine, comprising: a first casing having a mounting surface; andan annular mount having a surface that interfaces and mates with the mounting surface, wherein the surface has a plurality of channels extending therealong that allow for the passage of a secondary gas flow between the annular mount and the first casing, and wherein each channel extends along a length of the surface from a radially innermost edge to a radially outermost edge of the surface, and wherein each channel places a first cavity in flow communication with a second cavity;wherein the annular mount is disposed between the first cavity and the second cavity, and wherein the first and second cavities are partially defined by surfaces of the annular mount, and wherein a radially inner surface of the first casing at least partially defines the first cavity. 9. The assembly of claim 8, wherein the surface has an axially extending portion and a radially extending portion, and wherein the channels have an axially extending portion and a radially extending portion. 10. The assembly of claim 8, further comprising impingement holes that extend through the annular mount, wherein at least one of the channels communicates with impingement holes. 11. The assembly of claim 8, wherein the first casing is connected to the annular mount, and further comprising: a second casing mounted to the first casing by the annular mount, wherein the channels along the surface of the annular mount allow for the passage of a secondary gas flow between the first casing and the second casing. 12. The assembly of claim 11, wherein the channels extend both radially and laterally with respect to a centerline axis of the gas turbine engine. 13. The assembly of claim 12, wherein each channel crosses over an adjacent channel as each channel extends radially outward. 14. A turbine section for a gas turbine engine, comprising: a first casing extending along the turbine section and having an aft surface;a fairing disposed radially inward from the first casing to form a main gas path through which combustion gases can flow, wherein the first casing and fairing together form a first cavity disposed forward of the aft surface; andan annular mount disposed radially outward from the fairing and having a radially extending flange that interfaces and mates with the aft surface, wherein the flange has a plurality of channels extending along a surface thereof from a first radially innermost edge to a radially outermost edge, each channel allowing for the passage of a secondary gas flow from the first cavity to a second cavity, wherein the annular mount is disposed between the first cavity and the second cavity. 15. The turbine section of claim 14, wherein the flange has an axially extending portion, and wherein the channels have an axially extending portion along the extent of the axially extending portion. 16. The turbine section of claim 14, further comprising one or more passages that extend through the flange, wherein at least one of the channels communicates with one or more passages. 17. The turbine section of claim 14, wherein the first casing is connected to the annular mount, and further comprising: a second casing mounted to the first casing by the annular mount, wherein the channels along the surface of the annular mount allow for the passage of a secondary gas flow between the first casing and the second casing. 18. The turbine section of claim 14, wherein the annular mount comprises a mount ring that interacts with the fairing. 19. The turbine section of claim 18, further comprising a seal, wherein the annular mount comprises a seal land for the seal.
