Abstract
A component, such as for a turbine engine, can include an airfoil with an outer wall defining an exterior surface bounding an interior and defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a chord-wise direction and extending between a root and a tip to define a span-wise direction. The component can also include at least one cooling passage within the interior.
Claims26
An airfoil for a turbine engine, comprising:
- an outer wall defining an exterior surface bounding an interior and defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a chord-wise direction and extending between a root and a tip to define a span-wise direction;
- a first passage extending along one of the leading edge, the trailing edge, or the tip;
- a second passage extending along another of the leading edge, the trailing edge, or the tip;
- a first cooling air supply conduit comprising a first three-dimensional plexus of fluidly interconnected cooling passages fluidly coupled to one of the first passage or the second passage;
- and
- a second cooling air supply conduit comprising a non-furcated passage fluidly coupled to the other of the first passage or the second passage.
An airfoil for a turbine engine, comprising:
- an outer wall defining an exterior surface bounding an interior and defining a pressure side and a suction side extending between a leading edge and a trailing edge to define a chord-wise direction and extending between a root and a tip to define a span-wise direction;
- outlets on the exterior surface;
- and
- a first cooling air supply conduit having a first supply passage and a first three-dimensional plexus of fluidly interconnected cooling passages which are fluidly connected to the outlets, wherein the first supply passage is at least partially radially aligned with the first three-dimensional plexus.
A cooled component, comprising:
- an outer wall defining an exterior surface bounding an interior;
- outlets on the exterior surface;
- and
- a three-dimensional plexus of fluidly interconnected cooling passages located within the interior and fluidly coupled to the outlets, the three-dimensional plexus having at least one planar set of cooling passages.
