horisontaalteljelised

Horisontaalteljelised refers to a classification of wind turbines based on the orientation of their main rotor shaft. In this configuration, the rotor shaft is horizontal, meaning it is parallel to the ground. This is in contrast to vertical-axis wind turbines, where the rotor shaft is perpendicular to the ground. The vast majority of wind turbines currently in operation worldwide are horizontal-axis wind turbines, often abbreviated as HAWTs.

These turbines typically consist of a tower, a nacelle that houses the generator and other mechanical components, and blades that are mounted on a rotor. The blades are designed to capture kinetic energy from the wind and convert it into rotational energy. This rotational energy is then used to drive a generator, producing electricity. The horizontal orientation allows the rotor to face directly into the wind, maximizing energy capture. HAWTs are commonly found in large wind farms, both onshore and offshore. Their design has been refined over decades, leading to high efficiency and reliability. The ability to pitch the blades individually or collectively allows for control over rotor speed and power output, as well as protection during high winds.
