The incompressible flow field near the tip of a single-bladed rotor in hover has been studied using a 3-D unsteady Navier-Stokes code, and using laser velocimeter measurements. The computer code has been previously used to study steady and unsteady viscous flow past rotor blades. The flow field predictions close to the blade agree well with the velocity measurements, but there are some differences bar the leading edge off the blade tip. Measured velocity profiles across the tip vortex core reveal secondary features attributable to the difference in sense of rotation of the tip vortex and the trailing vortex sheet.
