Which Danish wind turbine, built in 1957, influenced the design of modern three-bladed turbines?

The Gedser wind turbine, built in Denmark in 1957, influenced the design of modern three-bladed turbines.

Designed by Johannes Juul, the Gedser turbine was installed on the Danish island of Falster. It used three blades, an asynchronous generator, electromechanical yaw control, and a stall-regulated rotor. These features made it an important practical example for later wind-turbine engineering.

The machine operated for years and was later examined by engineers developing wind power in the United States. Its simple, robust layout helped establish the “Danish concept”: a three-bladed, upwind rotor driving a generator in a nacelle.

Gedser was not the first wind turbine ever built, and it was not the first machine to generate electricity from wind. Its importance lies in demonstrating a durable configuration that became highly influential in commercial wind-turbine design.
