In one aspect, a winglet for a rotor blade is disclosed. The winglet may generally include a winglet body extending at least partially between a winglet origin and a blade tip.

The pre-bend defined between the winglet origin and the blade tip may range from about 1.5% to about 4.5% of the span of the rotor blade.
