Abstract
An internally cooled component of a gas turbine engine is provided. The component may include a cooling passage at least partially defined by a first wall and a second wall with a first pedestal extending from the first wall to the second wall. The first pedestal may have a chevron geometry. A second pedestal may extend from the first wall to the second wall and also have a chevron geometry. A gap may be defined by the first pedestal and the second pedestal with the gap oriented between the first pedestal and the second pedestal.
Claims15
A cooled component of a gas turbine engine, comprising:
- a cooling passage at least partially defined by a first wall and a second wall;
- a first pedestal extending from the first wall to the second wall, the first pedestal comprising a first chevron geometry;
- and
- a second pedestal extending from the first wall to the second wall, the second pedestal comprising a second chevron geometry, wherein a gap is defined by the first pedestal and the second pedestal with the gap oriented between the first pedestal and the second pedestal, wherein the first pedestal is oriented at an angle ranging from 140 degrees to 176 degrees relative to the second pedestal, and wherein the first pedestal comprises:
- a base disposed at the first wall of the cooling passage;
- a first flat segment extending from the base;
- a curved segment extending from the first flat segment;
- and
- a second flat segment extending from the curved segment.
An airfoil, comprising:
- an internal cooling passage;
- and
- a cooling feature formed in the internal cooling passage, the first cooling feature comprising:
- a first pedestal having a first chevron geometry, and
- a second pedestal having a second chevron geometry,
- wherein the first pedestal is oriented at an angle ranging from 140 degrees to 176 degrees relative to the second pedestal and comprises:
- a base disposed at a wall of the internal cooling passage;
- a first flat segment extending from the base;
- a curved segment extending from the first flat segment;
- and
- a second flat segment extending from the curved segment.
A cast core, comprising:
- a cooling passage at least partially defined by a first wall and a second wall;
- a first pedestal extending from the first wall to the second wall, the first pedestal comprising a first chevron geometry;
- a second pedestal extending from the first wall to the second wall, the second pedestal comprising a second chevron geometry, wherein a gap is defined by the first pedestal and the second pedestal with the gap oriented between the first pedestal and the second pedestal, wherein the first pedestal is oriented at an angle ranging from 140 degrees to 176 degrees relative to the second pedestal and comprises:
- a base disposed at the first wall of the cooling passage;
- a first flat segment extending from the base;
- a curved segment extending from the first flat segment;
- and
- a second flat segment extending from the curved segment.
