Investigation of Laminar Separation Bubble on Helicopter Blades
PIV results obtained with a mirror telescope objective at alpha = 11.55°, steady case. The magnitude of the velocity has been plotted color coded. The coordinates x and y are given in millimeters. The origin is placed on the model surface (y), 5% chord length behind the leading edge (x).
