Eolos Wind Turbine Video
The Eolos Wind Research Field Station is located at UMore Park, a 5,000-acre University-owned property in Dakota County (approximately 20 miles southeast of the Twin Cities campus). Eighty acres on the eastern portion of UMore Park have been dedicated to the research station, which includes a 2.5 MW Clipper Liberty wind turbine and a 130m (426 ft) tall meteorological tower. This site hosts not only active consortium research, but also education and training of next generation wind industry personnel. The major components of the research field station are described in the following sections.
Each of the turbine's three blades is instrumented with 10 fiber-optic strain gauges and 10 fiber optic temperature gauges to measure the strain in the blade material. Three tri-axial DC-accelerometers are also mounted inside each of the blades. Coordinated measurements from the strain gauges and the accelerometers allow researchers to determine the dynamic strain conditions on each of the blades and the resulting deflections.
