A metallic structure includes a metallic sheet, including a metallic-sheet first surface and a metallic-sheet second surface. The metallic structure includes a metallic doubler, extending from the metallic-sheet first surface, and a first junction between the metallic-sheet first surface and the metallic doubler. The metallic structure includes a metallic article, extending from the metallic-sheet second surface, and a second junction between the metallic-sheet second surface and the metallic article. The first junction has a first-junction boundary. The second junction has a second-junction boundary. When viewed at any point along the second-junction boundary in a direction, perpendicular to the metallic-sheet first surface, the second-junction boundary does not extend outside of the first-junction boundary. In a plane, intersecting the metallic doubler and perpendicular to the metallic-sheet first surface, the metallic doubler has at least a first doubler thickness and a second doubler thickness, which is less than the first doubler thickness.

Metallic structures with additively manufactured metallic articles and methods for fabrication

An envelope portion of an airborne craft comprises a metallic outer wall and a metallic inner wall arranged interior to the outer wall. The outer and inner walls delimit an inter-wall volume configured to support a flow of coolant to cool the outer wall during atmospheric heating of the outer wall.
