Abstract
A component for a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a platform having an outer surface and an inner surface that axially extend between a leading edge portion and a trailing edge portion. At least one augmentation feature is disposed on at least one of the leading edge portion and the trailing edge portion of the outer surface of the platform.
Claims20
A component for a gas turbine engine, comprising:
- a platform having an outer surface and an inner surface that axially extend between a leading edge portion and a trailing edge portion;
- and
- at least one augmentation feature disposed on at least one of said leading edge portion and said trailing edge portion of said outer surface of said platform.
A gas turbine engine, comprising:
- a compressor section;
- a combustor section in fluid communication with said compressor section;
- a turbine section in fluid communication with said combustor section;
- and
- wherein at least one of said compressor section and said turbine section includes:
- a first component having a platform that includes an outer surface and an inner surface that axially extend between a leading edge portion and a trailing edge portion;
- a second component mounted adjacent to said first component and including a platform;
- wherein a portion of said platform of said first component axially overlaps a portion of said platform of said second component, and said portion of said first platform includes at least one augmentation feature disposed on said outer surface of said platform.
5 more elements
A method of cooling a component of a gas turbine engine, comprising the steps of:
- cooling a platform of the component with a leakage airflow that is communicated from a cavity positioned radially inwardly from the component by circulating the leakage airflow over at least one augmentation feature that is disposed on an outer surface of the platform.
