ABSTRACT:
A blade and method for fabrication of a blade for use on a hub for rotation in a fluid that enjoys the benefits of a skewed blade without the disadvantages. This is accomplished through the use of alternating clockwise skewed and counterclockwise skewed sections formed along the leading edge. In bidirectional applications the alternating clockwise and counterclockwise skewed sections are formed along both edges.
