Abstract:
1. A method for configuring hollow helical wheels, comprising: providing at least one evolutive helical element; forming a leading edge of the evolutive helical element in the shape of a portion of a first selected geometric figure having a first reference center; forming a trailing edge of the evolutive helical element in the shape of a portion of a second selected geometric figure having a second reference center; and forming a web between the leading edge and the trailing edge, the web having an interior surface and an opposing exterior surface, the interior surface being in the shape of a portion of a third selected geometric figure having a third reference center, and the exterior edge being in the shape of a portion of a fourth selected geometric figure having a fourth reference center; wherein the distance from a central axis to each reference center is selectively chosen so as to tailor the shape of the evolutive helical element.
