Patent ID: 8419372

Claim:
An airfoil comprising: a suction side and a pressure side coupled together at a leading edge and a trailing edge, said airfoil is defined by a plurality of first chord sections defining at least one first chord length, and a plurality of second chord sections defining at least one second chord length, at least one chord section of said plurality of first chord sections extends outward from said airfoil pressure side at said trailing edge, and at least one chord section of said plurality of second chord sections extends outward from said airfoil suction side at said trailing edge, said trailing edge comprises: a plurality of spaced-apart wave-shaped projections, each wave-shaped projection of said plurality of wave-shaped projections defines a wave tip, wherein adjacent said wave-shaped projections define a tip-to-tip distance therebetween, the tip-to-tip distance is within a range of values representative of a percentage of the at least one first chord length, wherein said wave-shaped projections are at least one of substantially evenly spaced and unevenly spaced.
