A shape shifting foil alters the shape of a fluid foil contour by rotating a leading edge structure. A skin that forms the fluid foil contour is at least partially attached to the leading edge structure, and is wrapped around the leading edge structure so two edges of the skin form the trailing edge of the fluid foil. The two edges forming the trailing edge slide with respect to one another, thereby permitting the skin to shift when the leading edge structure is rotated.
1. A fluid foil comprising: a spar having a root section secured to a body and a tip end located distal from the body;an axle having a root section secured to the body and a tip end locatcd distal from the body;a leading edge structure defining a leading edge contour, the leading edge structure having a root section proximate the body and tip end distal from the body, and the leading edge structure attached to the axle for rotating the leading edge structure therewith with respect to the spar; anda skin having a root edge proximate the body, a tip edge d...
