The aerodynamic and structural design of the instrumented wind tunnel model is presented. The influence of many aerodynamic parameters on the dynamic stall is shown. The crossflow velocities lead to a delayed stall and a decreased lift at the kink. Time shifted flow separation occurs inboard and outboard of the kink. A sharp gradient in the global pitching moment is avoided.Read More
