ABSTRACT:
An aerodynamic-shaped fan blade for use in a fan apparatus. The blade has a cross-section which is essentially an inverted pan-shape with an intermediate section, a leading edge section, and a trailing edge section which form concave and convex surfaces. The trailing edge has a flange doubled back toward the leading edge within the concave envelope.
