Patent ID: 8323775

Claim:
A layer for reducing air resistance of a foreword-moving object, which layer comprises: a) a base surface; b) a pattern of projections extending from the base surface; c) wherein the pattern of projections comprises projections adjacent to each other in a direction substantially aligned with the direction of flow, and separate projections substantially adjacent to each other in a direction orthogonal to the direction of flow; d) each projection having a top surface which is inclined in a first direction relative to the base surface; e) wherein the top surface of each projection lies upon a geometric plane; f) wherein the top surface of each projection reduces air resistance of the forward-moving object by increasing micro-scale turbulence as the air passes over the pattern of projections extending from the base surface; g) wherein each projection comprises at least one groove running in the first direction; and h) channels running between each projection in a second direction at an angle to the first direction.
