Wind turbine blade length depends on your overall unit design power and wind field conditions. In the same wind field, the larger the power, the longer the blade. For the same power, a wind field with a lower average annual wind speed needs longer blades. In fact, according to the research, different wind fields need corresponding power fans to achieve the real cost performance. In addition, blades of the same length have different power due to airfoil differences. Therefore, the blade manufacturers try to optimize the blade structure. In fact, determining the exact shape of a really good blade is a very complicated process, very high in hydrodynamic, very high in aerodynamics.
The rotor blades of wind turbines measure about 20 meters in length and are designed much like the wings of an airplane. The power generation varies according to the type of generator. The most widely used type in the world is the horizontal shaft generator, with a maximum power of about 5MW.
