Title: Wind turbine blades, wind turbines, and wind farms having increased power output

Patent · Tue Sep 03 00:00:00 EDT 2019

OSTI ID:1576392

Kelley, Christopher Lee; Maniaci, David Charles; Resor, Brian R.

A wind turbine blade having a geometry that decreases the distance downstream at which freestream momentum is recovered is disclosed. The blade design increases the loading on the inboard portion of the blade and unloads the tip portion relative to a conventional blade designed to maximize power coefficient. A wind farm having a reduced inter-turbine distance and including one or more wind turbines having the new blade designs is also disclosed.
