Abstract
Dynamic stall is experimentally and numerically investigated on a pitching double-swept helicopter rotor blade tip. 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.
