Abstract

To investigate the development of blade tip vortices under different rotor conditions like thrust and rotational speed, both 2C and 3C 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° 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° to generate a 3D 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.
