Abstract
An article including an airfoil or hydrofoil is disclosed. On at least a portion of a surface of the airfoil or hydrofoil there is a seamless film having a series of substantially parallel peaks separated from each other by a series of substantially parallel valleys on a patterned first surface of the film, wherein the seamless film has a long dimension that is at least two meters long substantially aligned with the span of the airfoil or hydrofoil, and wherein an angle between the parallel peaks and valleys to the long dimension of the seamless film is at least five degrees. Methods of making the article are also disclosed.
