Design and Development of a Compressible Dynamic Stall Facility
Abstract
A dynamic stall facility offering a unique new capability for studies of compressibility effects on dynamic stall is described. This facility features complete visual access by mounting the test airfoil between optical-quality glass windows which are rotated in unison to produce the oscillating airfoil motion associated with helicopter rotor dynamic stall. By using the density gradients associated with the rapidly changing dynamic stall flow field, this facility permits simultaneous detailed investigation of the flow on the surface as well as in the flow field surrounding airfoils experiencing dynamic stall. Keywords: Dynamic stall; Compressibility effects, Unsteady viscous aerodynamics, Wind tunnel design, Stroboscopic schlieren flow visualization.
