Aerodyn Engineering Gmbh

Sönke Siegfriedsen founded the company aerodyn in 1983, which has now been active as an independent engineering and consulting office for wind turbines for 40 years. Due to these early activities, Sönke Siegfriedsen is regarded as a pioneer in the wind energy industry. As early as 1984, a year after being founded, aerodyn undertook groundbreaking work with the first complete development of a 25 kW wind turbine and its testing in the test field on the North Sea island of Pellworm. This initial project delivered well-founded knowledge about aerodynamic behaviour, mechanical loads and turbine control engineering. Over the following 40 years aerodyn has developed nearly 30 types of wind turbines, from 5 to 10.000 kW, and has worked for companies around the world. Wind turbines designed from aerodyn, or in whose development aerodyn played a significant role, are producing energy on all five continents, with more than 50.000 turbines.
