Abstract

A component for a gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a wall that forms a portion of an outer periphery of at least one cavity and at least one curved turbulator that extends from said wall.

First claim

What is claimed is:

1. A component for a gas turbine engine, comprising:
a first wall that forms a portion of an outer periphery of at least one cavity;
at least one curved turbulator that extends from said first wall in a first direction and into a cavity flow path of said at least one cavity, said cavity flow path defined between said first wall and a second, opposed wall, and said at least one curved turbulator spaced apart from said second wall such that said cavity flow path extends over said at least one curved turbulator; and
wherein said at least one curved turbulator includes a contiguous body having at least one peak and at least one valley in a longitudinal second direction.

2. The component as recited in claim 1 , wherein said component is one of a blade and a vane.

3. The component as recited in claim 1 , wherein said component is a blade outer air seal (BOAS).

4. The component as recited in claim 1 , comprising a plurality of curved turbulators spaced along said first wall.

5. The component as recited in claim 1 , wherein said contiguous body provides a smooth surface that excludes any sharp transition areas.

6. The component as recited in claim 1 , wherein said at least one curved turbulator is sinusoidal shaped.

7. The component as recited in claim 1 , comprising a row of film cooling holes spaced from said at least one curved turbulator.

8. The component as recited in claim 7 , wherein said row of film cooling holes includes a first film cooling hole and a second film cooling hole staggered from said first film cooling hole.

9. The component as recited in claim 1 , comprising a second turbulator that extends from said first wall and includes a different shape from said at least one curved turbulator.

10. The component as recited in claim 1 , wherein said at least one curved turbulator extends across a width of said first wall.

11. The component as recited in claim 1 , wherein said at least one curved turbulator extends perpendicular to a direction of flow of cooling airflow communicated through said at least one cavity.

12. A component for a gas turbine engine, comprising:
a first curved turbulator that protrudes from a first wall in a first direction and into a cavity flow path, said cavity flow path defined between said first wall and a second, opposed wall, and said first curved turbulator spaced apart from said second wall such that said cavity flow path extends over said first curved turbulator;
a second curved turbulator that protrudes from said first wall in a first direction and into said cavity flow path at a position that is spaced from said first curved turbulator, and said second curved turbulator spaced apart from said second wall such that said cavity flow path extends over said second curved turbulator;
a row of film cooling holes disposed between said first curved turbulator and said second curved turbulator; and
wherein each of said first curved turbulator and second curved turbulator includes a contiguous body having at least one peak and at least one valley in a longitudinal second direction.

13. The component as recited in claim 12 , wherein said row of film cooling holes includes a first film cooling hole and a second film cooling hole that is staggered from said first film cooling hole.

14. The component as recited in claim 12 , wherein said first curved turbulator and said second curved turbulator are sinusoidal shaped.

15. The component as recited in claim 12 , wherein a pitch between said first curved turbulator and said second curved turbulator is continuously varied.

16. A gas turbine engine, comprising:
a compressor section;
a combustor section in fluid communication with said compressor section;
a turbine section in fluid communication said combustor section;
a component that extends into a core flow path of at least one of said compressor section and said turbine section, wherein said component includes:
a first wall that forms a portion of an outer periphery of at least one cavity of said component;
at least one curved turbulator that extends from said first wall in a first direction and into a cavity flow path of said at least one cavity, said cavity flow path defined between said first wall and a second, opposed wall, and said at least one curved turbulator spaced apart from said second wall such that said cavity flow path extends over said at least one curved turbulator; and
wherein said at least one curved turbulator includes a contiguous body having at least one peak and at least one valley in a longitudinal second direction.

17. The gas turbine engine as recited in claim 16 , wherein said component is an airfoil of said turbine section.

18. The gas turbine engine as recited in claim 16 , wherein said component is a blade outer air seal (BOAS).

19. The gas turbine engine as recited in claim 16 , wherein said first wall is part of a platform of said component.

20. The gas turbine engine as recited in claim 17 , wherein said component includes a first rib and a second, opposed rib that each extend between said first wall and said second wall to bound said cavity flow path, and said at least one curved turbulator is defined between said first rib and said second rib.
