Abstract
A technique for repairing a dual walled component comprising a spar comprising a plurality of pedestals and a coversheet attached to the plurality of pedestals may include removing a damaged portion of the coversheet from the dual walled component to expose a plurality of exposed pedestals and define a repair location and an adjacent coversheet portion. The technique also may include attaching a material to the plurality of exposed pedestals and adjacent coversheet portion using directed energy deposition material addition to form a repaired coversheet portion.

A method for repairing a dual walled component comprising a spar comprising a plurality of pedestals and a coversheet attached to the plurality of pedestals, the method comprising:
- removing a damaged portion of a coversheet from a dual walled component to expose a plurality of exposed pedestals and define a repair location and an adjacent coversheet portion, wherein the dual walled component comprises:
- a spar comprising a plurality of pedestals, wherein the plurality of pedestals comprises the plurality of exposed pedestals;
- and
- the coversheet, wherein the coversheet is attached to the plurality of pedestals;
- and
- attaching a material to the plurality of exposed pedestals and adjacent coversheet portion using directed energy deposition material addition to form a repaired coversheet portion.
A dual walled component comprising:
- a spar comprising a plurality of pedestals;
- a coversheet attached to a first set of pedestals from the plurality of pedestals;
- and
- a repaired coversheet portion attached to a second set of pedestals from the plurality of pedestals and to the coversheet, wherein the repaired coversheet portion includes material attached using directed energy deposition material addition.
