Abstract: This invention, though preferably applied to aircraft structure, has application to foil-bearing devices in general, creating structure somewhat similar to the structure of a mobius band surface which characteristically rejoins to itself, because said structure produces unique continuity of one surface blending into a subsequent one, said structure most often having opposed higher and lower pressure-dynamic surfaces. These “mobius-like” structures join foil segments and complementary surfaces to specific fluid-dynamic components (foil segments joined to foil extensions, shaped and contoured panels, subsequent foil segments, and moveable surfaces) such that there is particular unique continuity of a first fluid-dynamic component to a subsequent one thus more effectively utilizing foil-created fluid-dynamic pressure flow for orchestrated lift and thrust production and reducing vortex-induced fluid-dynamic drag than have other inventions of the prior art.
