Abstract
Fan blades, characterized in that, being flexible preferably of plastic or rubber material, they present their curved-convex leading edge, so that the plane determined by the axis of the hub and the midpoint of the base the blade, cut to said edge, delaying the curvature of this as it approaches the vertex, and that the line of minimum distance between the vertex and the base of the blade, is positioned so that the leading edge is taut with the maximum force when turning the bushing, all this being given the circumstance of riding the paddle in the bushing so that the base of the bushing has a suitable inclination with respect to the axis of the bushing and with respect to the front thereof a suitable concavity.
