Abstract
A radial exhaust gas turbine apparatus has a gas turbine engine that includes a radial exhaust diffuser section and a casing apparatus consisting essentially of polygonal walls, substantially straight plates, and substantially straight sidewalls. The casing apparatus encloses the radial exhaust diffuser section and is configured to direct at least a substantial portion of the gas exiting the radial exhaust diffuser section to an exit in the casing apparatus via an approximately involute path.
Claims18
An involute type casing apparatus for a gas turbine engine that includes a radial exhaust diffuser, said apparatus comprising:
- a turbine engagement wall having an entry opening;
- an exhaust diffuser engagement wall spaced a distance from said turbine engagement wall, said diffuser engagement wall comprising an engine shaft hole sized and oriented to said radial exhaust diffuser;
- a plurality of substantially straight sidewalls coupled to or adjacent to edges of said turbine engagement walls and to or adjacent to edges of said exhaust diffuser engagement wall;
- and
- a plurality of substantially planar plates coupled to or adjacent to other edges of said turbine engagement wall and to or adjacent to other edges of said exhaust diffuser engagement wall, such that said substantially planar plates approximate a portion of a cycle of an involute curve;
- said apparatus configured to enclose the radial exhaust diffuser;
- and the top plate, bottom plate, substantially straight sidewalls, and substantially straight plates are engaged so that exhaust from the radial exhaust diffuser exits the apparatus via an outlet side.
A radial exhaust gas turbine apparatus comprising:
- an inlet section;
- a compressor section operatively coupled to the inlet section;
- a combustor section operatively coupled to the compressor section;
- a turbine section operatively coupled to the combustor section;
- a radial exhaust diffuser operatively coupled to the turbine section;
- and
- an involute type casing enclosing a radial exhaust diffuser,
- wherein the involute type casing further comprises:
- a turbine engagement wall having an entry opening;
- an exhaust diffuser engagement wall spaced a distance from said turbine engagement wall, said diffuser engagement wall comprising an engine shaft hole sized and oriented to said radial exhaust diffuser;
- a plurality of substantially planar plates coupled to or adjacent to other edges of said turbine engagement wall and to or adjacent to other edges of said exhaust diffuser engagement wall, such that said substantially planar plates approximate a portion of a cycle of an involute curve;
- and
- a plurality of substantially straight plates coupled to said turbine engagement wall such that said substantially straight plates are adjacent to outer edges of said exhaust diffuser engagement wall, approximating a portion of a cycle of an involute curve;
- wherein the top plate, bottom plate, substantially straight walls, and substantially straight plates are engaged so that exhaust from the exhaust diffuser exits the involute type casing apparatus via an outlet side.
A radial exhaust gas turbine apparatus comprising:
- gas turbine engine that includes a radial exhaust diffuser section;
- and
- a casing apparatus consisting essentially of polygonal walls, substantially straight plates, and substantially straight sidewalls;
- said casing apparatus enclosing the radial exhaust diffuser section and configured to direct at least a substantial portion of the gas exiting the radial exhaust diffuser section to an exit in the casing apparatus via an approximately involute path.
