ABSTRACT:
An edge for frontal engagement with air flow as occurs when vehicles are moving in an air environment. The edge is elongate and intended to wrap around an existing corner where two substantially planar surfaces intersect, one of the planar surfaces being a front surface and the other planar surface being a rearwardly receding flanking surface such as a top surface or a side surface of a vehicle. The edge rises abruptly from the front plane and moves forwardly and outwardly in a convex arc to a point of abrupt inflection outside of the flanking plane and adjacent the front plane as extended through the flanking plane. The discontinuity or inflection is a change from convexity to concavity formed by alternate concavity and convexity and progressing generally toward faired contact with the flank plane.
