Aerodynamic Forces Affecting the H-Rotor Darrieus Wind Turbine
A lot of parameters are influencing aerodynamically the performance of the vertical axis wind turbines. The essential forces created over any airfoil are the drag forces and lift forces. Lift forces to drag forces ratio is a function of turbines solidities, airfoil section profiles, speed ratios, and wind speeds.

Development of the Risø wind turbine airfoils
The Risø-P airfoils were developed to replace the Risø-A1 airfoils for use on pitch controlled wind turbines. Improved design objectives should reduce the sensitivity to roughness, but measurements are not yet available. The Risø-B1 airfoil family was developed for variable speed operation with pitch control of large megawatt sized rotors.
