Aeroprobe’s instrumentation employed by Denmark’s Risoe National Laboratory

Aeroprobes mounted on several different wind turbines have provided inflow data for tests performed by Risoe National Laboratory and their partners. The image on the left shows Aeroprobe probes mounted on the blade leading edge of a 2MW, 80m rotor (photo courtesy of Vestas/Siemens/Risoe National Lab). The data acquired over the rotor plane has been used to compare inflow at various parts of the rotor disc. Typical upstream tower measurements cannot provide this information.

Risoe researchers have shown that the inflow data can provide input to a method that can be used to calculate the wind shear and turbulence in the freestream. This method was demonstrated in tests on a 3.6MW turbine. It was found that wind shear and turbulence varied considerably from one position of the blade to another – a result made possible by application of the probes.
