Abstract
A component for a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a platform having a first path side and a second path side and a platform cooling circuit disposed on one of the first path side and the second path side of the platform. The platform cooling circuit includes a first core cavity, a cavity in fluid communication with the first core cavity, and a cover plate positioned to cover at least the cavity.
Claims17
A component for a gas turbine engine, comprising:
- a platform having a first path side and a second path side;
- and
- a platform cooling circuit disposed on one of said first path side and said second path side of said platform, wherein said platform cooling circuit includes:
- a first core cavity;
- a serpentine cavity in fluid communication with said first core cavity;
- a cover plate shaped similar to the serpentine cavity and positioned to cover at least said serpentine cavity, wherein said first core cavity is at least partially uncovered by said cover plate;
- a plurality of openings through said cover plate, wherein said openings are configured to communicate impingement cooling airflow to said serpentine cavity.
A component for a gas turbine engine, comprising:
- a platform having a first path side and a second path side;
- and
- a platform cooling circuit disposed on one of said first path side and said second path side of said platform, wherein said platform cooling circuit includes:
- a first core cavity;
- a serpentine cavity in fluid communication with said first core cavity;
- a cover plate shaped similar to the serpentine cavity and positioned to cover at least said serpentine cavity, wherein said first core cavity is at least partially uncovered by said cover plate, wherein said platform cooling circuit includes a second core cavity adjacent said first core cavity and in fluid communication with said serpentine cavity, wherein said second core cavity is at least partially uncovered by said cover plate.
A component for a gas turbine engine, comprising:
- a platform having a first path side and a second path side;
- and
- a platform cooling circuit disposed on one of said first path side and said second path side of said platform, wherein said platform cooling circuit includes:
- a first core cavity;
- a serpentine cavity in fluid communication with said first core cavity;
- an impingement cavity that is separate from said serpentine cavity;
- and
- a cover plate shaped similar to said serpentine cavity and positioned to cover at least said serpentine cavity and said impingement cavity, wherein said impingement cavity is generally L-shaped, and the platform extends circumferentially between first and second mate faces, and the impingement cavity is positioned adjacent a trailing edge of the platform and extends from a position adjacent the first mate face to a position adjacent the second mate face.
