Abstract
Additive manufacturing techniques may be utilized to construct effusion plates. Such additive manufacturing techniques may include defining a configuration for an effusion plate having one or more internal cooling channels. The manufacturing techniques may further include depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a cross-sectional shape corresponding to the defined configuration. Such methods may be implemented to construct an effusion plate having one or more channels with a curved cross-sectional geometry.
Claims15
A turbine combustor, comprising:
- a combustion chamber;
- a head end portion;
- and
- an effusion plate positioned between the combustion chamber and the head end portion, the effusion plate comprising:
- a proximal face;
- a distal face;
- and
- one or more channels extending between the proximal face and the distal face, wherein the one or more channels comprise a serpentine cross-sectional geometry, wherein the cross-section is taken along a plane extending between the proximal face and distal face.
A system, comprising:
- an effusion plate configured to be attached to a turbine combustor and positioned between a combustion chamber and a head end portion of the turbine combustor, comprising:
- a proximal face;
- a distal face;
- and
- one or more channels extending between the proximal face and the distal face, wherein the one or more channels comprise a curved cross-sectional geometry such that the one or more channels intersect a plane extending between the proximal face and distal face multiple times, wherein the plane is perpendicular to the proximal face or the distal face.
