ABSTRACT:
A fan blade comprising a body having a tip end and an in-board end is configured with first and second fin portions that extend along the trailing edge of the body of the fan blade. The first fin portion extends from the in-board end of the fan blade along the trailing edge toward the tip end, while the second fin portion extends from the tip end of the fan blade along the trailing edge toward the in-board end. Both the first and second fin portions extend outwardly from the trailing edge of the body at an angle to this trailing edge. Generally a slot or gap would exist between these first and second fin portions and both such fin portions would have a tapered width which narrows in the direction of the tip end. Additionally, the width of the first fin portion would be greater than the width of the second fin portion. Furthermore, the two fin portions may or may not be co-planar in order to optimize air flow.
