A method of fabricating an exhaust hood for use with a turbine engine, said method comprising:
- providing an upper shell casing wherein the upper shell casing is fabricated from a composite material;
- and
- coupling the upper shell casing to a lower shell casing such that a turbine is housed within the exhaust hood, the lower shell casing is fabricated from a composite material;
- and
- coupling an inner skin to a radially inner surface of the upper and lower shell casings.
A turbine exhaust hood comprising:
- a shell casing sized to house a turbine at least partially therein, said shell casing is fabricated from a composite material, wherein said shell casing further comprises an inner skin coupled to a radially inner surface of said shell casing.
A turbine assembly comprising:
- a turbine;
- and
- an exhaust hood such that said turbine housed at least partially within said exhaust hood, said exhaust hood comprising:
- a shell casing comprising a radially inner surface and a radially outer surface, wherein an inner skin is coupled to the radially inner surface, said shell casing is fabricated from a composite material;
- an external support structure coupled to said shell casing outer surface, said external support structure provides structural support to said shell casing;
- and
- an internal support structure coupled to said shell casing inner surface for channeling flow into said exhaust hood.
