Abstract
A turbine component includes a body having a pair of spaced walls, with at least one of the walls for facing a fluid flow when mounted in a gas turbine engine. There are a plurality of wall cooling passages having a generally boomerang shape such that a peak apex is spaced from the wall and an indent apex is adjacent to the wall, with the plurality of wall cooling passages having interior sides extending from the peak apex toward the wall to define a corner. Outer sides extend from the corners with a component away from the wall and to the indent apex. A gas turbine engine is also disclosed.
Claims17
A turbine component comprising:
- a body having a pair of spaced walls, with at least one of the walls for facing a fluid flow when mounted in a gas turbine engine, there being a plurality of wall cooling passages having a boomerang shape such that a peak apex is spaced from the wall and an indent apex is adjacent to the wall, with the plurality of wall cooling passages having interior sides extending from the peak apex toward the wall to define a corner, and outer sides extending from the corners with a component away from the wall and to the indent apex;
- wherein at least some of the pressure side wall cooling passages and at least one of the suction side wall cooling passages having a film cooling hole extending from at least one of the pressure side into the pressure side wall cooling passages or from the suction side into the suction side wall cooling passages and into the indent apex;
- wherein at least some of the film cooling hole on the pressure side extend from the pressure side wall into the pressure side wall cooling passages at the indent apex, and at least some of the film cooling holes on the suction side extend into the suction side wall cooling passages at the indent apex;
- and
- wherein the film cooling holes associated with each of the wall cooling passages on the pressure side and the suction side have a first meter portion communicating to the pressure side wall cooling passages and said suction side wall cooling passages and an enlarged diffused portion connecting the first meter portion to an outer surface of the respective one of this pressure side and suction side.

- and
- wherein a width is defined between the corners of the at least one of the wall cooling passages and wherein an indent height is defined between a line connecting two points at each side of each of the wall cooling passages that are closest to the associated wall and the indent apex and a ratio of the indent height to the width is greater than or equal to 0.05 and less than or equal to 0.3.
