This chapter provides guidelines for designing utility-scale wind turbines for wind tunnel testing. While one might think scaling down all dimensions of a utility-scale wind turbine with the same scale factor suffices, the aerodynamic results obtained for such a scale model significantly differ from those of the full-scale turbine. It is essential to scale a turbine so that its power coefficient and tip speed ratio remain unchanged.
