How to judge whether a wind turbine is a lift type or a drag type

Horizontal axis wind turbines can be divided into two types: lift type and drag type. Lift-type wind turbines rotate quickly, while drag-type wind turbines rotate slowly. For wind power generation, lift-type horizontal axis wind turbines are mostly used. Most horizontal axis wind turbines have wind-facing devices that can rotate as the wind direction changes. For small wind turbines, this wind-facing device uses a tail rudder, while for large wind turbines, a transmission mechanism composed of wind direction sensing elements and servo motors is used.
