摘要：
Phase-resolved laser Doppler measurements were made of the three-dimensional velocity field and tip vortex structure in the wake of a hovering rotor. A one-bladed rotor was used to generate a single and nominally helical shaped vortex filament in the rotor flow field. The measurements were analyzed to establish the detailed structure of the tip vortex, such as the tangential and axial velocity profiles, circulation profiles, and viscous core growth with vortex age.
