A free-flight full-scale out-door test to localize blade tip vortices of a helicopter in space was performed by means of the stereoscopic Background Oriented Schlieren method (BOS) at the DLR site and research flight center in Braunschweig. The objective was a quantitative feasibility study of the BOS measurement technique for spatial vortex investigations. The results show that it is possible to detect and to measure the position of three-dimensional vortex structures of a free-flying MBB Bo 105 helicopter in space.
