Swift, but strong Rotor blades need to be as aerodynamic as possible, while at the same time be able to handle extreme loads when wind speeds rise. The root section especially requires a robust structure to withstand the force of the wind. Therefore, rotor blade design is always a compromise between the aerodynamic optimum and structural stability. This, in turn, opens up for the opportunity to install specially designed add-ons to modify the airflow around the blades and make up for the aerodynamic losses caused by the design compromise.
