Short summary
The wind speed measured by a flow sensor mounted on the blade of a wind turbine is disturbed by the turbine. This paper presents a method to obtain the free turbulence inflow by compensating for this disturbance. The method is tested using numerical simulations and can be used to extract inflow information for accurate aeroelastic load simulations.
