Abstract : The report summarizes the results and conclusions reached in an experimental study of the nature of the unsteady flow about bluff bodies. The flows studied included the flow about a sphere, a disk with face normal to the flow, and an autorotating two-dimensional airfoil. The studies included flow visualization, measurements of unsteady forces and moments, the development of a low Reynolds number towing tank with air bearing carriage and detailed studies of the unsteady inviscid flow field generated by shedding of wake vorticity.
