The New Approach in 3D Wind and Turbulence Sensing: uSonic-3 Multi-Path

What is the best approach for surveying the wind field in wind farms? In this discussion usually the reliability of in-situ measurements is played off against the representativeness of remote sensing techniques. In the joint research project LIDAR Complex, the IFB (University of Stuttgart, Institute of Aircraft Design) found a new answer by combining the advantages of both approaches. They attached a uSonic-3 to an electrically powered UAV developed by IFB (http://www.uni-stuttgart.de/windenergie/lidarcomplex/).
