Abstract
A conduction riser additively manufactured onto thin metal parts, the conduction riser extending in a build direction of the thin metal part and traversing the thin metal part as the conduction riser extends in the build direction. The conduction riser transferring heat from the upper layers of additively manufactured part during manufacturing, preventing thermal deflection of the part.
Claims13
A gas turbine component comprising:
- a thin metal part, the thin metal part manufactured with an additive manufacturing process, wherein the thin metal part is an impingement baffle, the impingement baffle comprising:
- a supply side disposed opposite an exit side;
- a conduction riser joined to the supply side of the impingement baffle, the conduction riser and the impingement baffle concurrently manufactured with the additive manufacturing process;
- and
- a plurality of impingement holes extending through the impingement baffle from the supply side to the exit side, wherein at least one impingement holes of the plurality of impingement holes extends through the conduction riser, and wherein the at least one impingement hole is configured to direct a flow of cooling air onto a second gas turbine component.

A conduction riser for an additively manufactured impingement baffle, the conduction riser comprising:
- a projection additively manufactured onto a supply side surface of the additively manufactured impingement baffle, the projection normal to the supply side surface;
- the projection traversing the supply side surface of the impingement baffle;
- and
- the projection having a continuous cross-section;
- wherein at least one impingement hole extends through the projection to an exit side of the additively manufactured impingement baffle, the at least one impingement hole configured to direct a flow of cooling air onto a gas turbine component.
