Abstract
A fan blade configuration for a radial fan includes support structure for the cantilevered portion of each blade. This support structure is preferably affixed to an upper circumferential ring of the radial fan and extends outwardly therefrom in support of the cantilevered portion of the blade. The support structure preferably extends along the cantilevered portion of the blade for a predefined distance. The distance is preferably expressed relative to a distance to a point at which the leading edge of the blade terminates. The predefined distance is also a function of the downward inclination of the support structure extending along the cantilevered portion. The support structure extends underneath the outer ring so as to define an aligning surface for the rearward portion of the respective fan blade.
