Wind Turbine Airfoil List

2012-7-6  Wind Turbine Airfoil List. Through a subcontract with Airfoils Inc., NREL developed dozens of new airfoils intended for use with wind turbines. A primary design requirement of the new airfoils was insensitivity to roughness. Field tests have confirmed the achievement of this goal for some of the airfoils.

An airfoil optimization technique for wind turbines

2012-10-1  For instance, in wind turbines the airfoil can be used at a higher angle of attack, sometimes even achieving stall, and the most important parameter is the lift-to-drag ratio . In aircraft design, the objective of the design process might be quite different, such as decreasing the drag for a fixed lift coefficient [10] .

Airfoil Characteristics for Wind Turbines

2010-7-31  The airfoil characteristics used in BEM are mostly based on 2D wind tunnel measurements on airfoils. However, a direct use of 2D wind tunnel measure-ments cannot reproduce the measured power. Such data are known to under-predict the forces acting on the blades in stalled conditions (Rasmussen, 1983).
