Abstract

A turbine exhaust case for a gas turbine engine includes a multiple of CMC turbine exhaust case struts between a CMC core nacelle aft portion and a CMC tail cone.

Claims (27)

1 . A turbine exhaust case for a gas turbine engine comprising:

a CMC core nacelle aft portion;

a CMC tail cone; and

a multiple of CMC turbine exhaust case struts between said CMC core nacelle aft portion and said CMC tail cone.

2 . The turbine exhaust case as recited in claim 1 , wherein said CMC core nacelle aft portion defines a trailing edge of a core nacelle

3 . The turbine exhaust case as recited in claim 1 , wherein said CMC core nacelle aft portion defines a portion of an outer aerodynamic surface to provide essentially uninterrupted flow along a core nacelle

4 . A gas turbine engine comprising:

a turbine case; and

a CMC turbine exhaust case mounted to said turbine case.

5 . The gas turbine engine as recited in claim 4 , wherein said turbine case is a low pressure turbine case.

6 . The gas turbine engine as recited in claim 4 , wherein said turbine case is manufactured of CMC.

7 . The gas turbine engine as recited in claim 4 , wherein said CMC turbine exhaust case comprises:

a CMC core nacelle aft portion;

a CMC tail cone; and

a multiple of CMC turbine exhaust case struts between said CMC core nacelle aft portion and said CMC tail cone.

8 . The gas turbine engine as recited in claim 4 , wherein said CMC turbine exhaust case is mounted to said turbine case at a flange.

9 . The gas turbine engine as recited in claim 4 , wherein said multiple of CMC turbine exhaust case struts are bonded between said CMC core nacelle aft portion and said CMC tail cone.

10 . A method of assembling a gas turbine engine comprising:

mounting a CMC turbine exhaust case to a turbine case.

11 . The method as recited in claim 10 , further comprising:

bolting the CMC turbine exhaust case to the turbine case.

12 . The method as recited in claim 10 , further comprising:

defining at least a portion of a core nacelle with the CMC turbine exhaust case.

13 . The method as recited in claim 10 , further comprising:

defining at least a portion of an aerodynamic outer surface of a core nacelle with the CMC turbine exhaust case.

14 . The method as recited in claim 10 , further comprising:

defining a trailing edge of a core nacelle with the CMC turbine exhaust case.
