Visualizing Dynamic-Stall AirflowsWind-tunnel apparatus facilitates experiments on airfoils undergoing dynamic stall. Possible to visualize flow on oscillating airfoils nonintrusively. In new apparatus, mounting structure also viewing window: airfoil pin-mounted between two optical-quality glass windows. Windows oscillated simultaneously, giving unobstructed view of complex flow around pitching airfoil.
