Abstract
A fan blade design includes a hub and a plurality of blades connected to the hub. Each of the blades is a swept-back blade and has a leading edge and a trailing edge disposed opposite the leading edge. The trailing edge includes a first concave arc segment and a second concave arc segment, the first concave arc segment being positioned closer to the hub than the second concave arc segment. A chord length of the first concave arc segment is greater than a chord length of the second concave arc segment.
