Abstract
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 their creation at the trailing edge of the blade up to half a revolution behind the blade with azimuth steps between 1° to 10° and different spatial resolutions. In addition, a sequence of three-component measurements was performed just after the vortex creation at finer azimuth steps of 0.056° in order to generate a three-dimensional volumetric data set of the blade tip vortex. The influence of the PIV image analysis parameters on the vortex parameters derived -in particular sampling window size and window overlap- has been investigated. The measurements presented are part of the HOTIS (HOver TIp vortex Structure) project.
