Abstract
Flow field measurements of the blade tip vortices at a rotating helicopter rotor model were performed by three component laser-Doppler velocimetry (3D-LDV) and conventional (two component) particle image velocimetry (PIV). The results are in good correspondence in general, but alo illustrate the different properties of both techniques, such as the three-dimensional measurement capability of LDV and the unsteadyness of the flow captured by the PIV method.
