Wind turbine blade dynamic stall is studied in a custom-built unsteady wind tunnel facility. The synchronous variations in angle of attack and relative flow speed are reproduced. The matched pitch rate concept is extended to conditions representative of wind turbine rotor blades. A close agreement between the matched data sets is observed.
