Unconventional wind turbines Wikipedia

Horizontal axis Twin-bladed rotor. Nearly all modern wind turbines use rotors with three blades, but some use only two blades. This was the type used at Kaiser-Wilhelm-Koog, Germany, where a large experimental two-bladed unit—the GROWIAN, or Große Windkraftanlage (big wind turbine)—operated from 1983 to 1987. Other prototypes and wind turbine types were manufactured by NedWind.

Horizontal-axis wind turbines (HAWT) have the main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind. Small turbines are pointed by a simple wind vane, while large turbines generally use a wind sensor coupled with a servo motor. Most have a gearbox, which turns the slow rotation of the blades into a quicker rotation that is more suitable to drive an

How Windmills Generate Energy How Wind Turbines

In turn, the rotor causes the main shaft inside the turbine to spin, which generates electricity. The basics of how windmills and wind turbines generate power centers on the wind pushing on the blades of the wind turbine. But how does this motion get converted into electricity? In reality, wind energy already gets used to fly a kite or activate a windchime or sail a sailboat. A wind turbine

Fiberglass rotor blades often incorporate a large amount of inboard planform area and twist, and may carry the maximum chord quite far in toward the root (Stoddard, 1989). For a given rotor diameter, this will produce the most power, albeit at the cost of a significant increase in total blade surface area and materials.
