In order to investigate the development of blade tip vortices under different rotor conditions like thrust and rotational speed, both two-and three-component PIV measurements were performed on a 40% Mach scaled BO105 model rotor in hover condition. The vortices were traced from the trailing edge of the blade up to half a revolution behind the blade with azimuth steps between 1 and 10° and different spatial resolutions. In addition, a sequence of three-component measurements was performed just after the vortex creation at finer azimuth step of 0.056° in order to generate a three-dimensional volumetric data set of the blade tip vortex.
