Question
Q.5. How many types of wind turbine are there? Name them.
Answer
Wind turbines are classified by axis orientation into two types: Horizontal Axis Wind Turbines (HAWT), where the rotor shaft is horizontal/parallel to the ground, and Vertical Axis Wind Turbines (VAWT), where the rotor shaft is vertical (e.g., Darrieus, Savonius types).
There are two main types of wind turbines based on the axis of rotation: (1) Horizontal Axis Wind Turbine (HAWT) — the most common type, with blades rotating about a horizontal axis parallel to the wind direction, requiring a yaw mechanism to face the wind; (2) Vertical Axis Wind Turbine (VAWT) — the rotor shaft is vertical, perpendicular to the ground, and can accept wind from any direction without yawing; common designs include the Darrieus turbine (curved 'egg-beater' blades) and the Savonius turbine (drag-type, S-shaped blades).
