ABSTRACT:
A fan10includes a hub12, a plurality of fan blades14attached to the hub at one end and extending outwardly from the hub, and a ring18concentric with the hub and coupled to tips16of the blades. A dimensionless radius (r/R) is defined from a center of the hub (r/R=0) radially outwardly, wherein each tip of the blades is r/R=1. A pitch ratio increases up to about r/R=0.85, and decreases in a range of about 0.85<r/R<1.0. In the range of about 0.6<r/R<1.0, a chord length decreases continually.
