Short summary
This paper describes a new formulation for estimating the wind inflow at the rotor disk, based on measurements of the blade loads. The new method improves on previous formulations by exploiting the rotational symmetry of the problem. Experimental results obtained with an aeroelastically scaled model in a boundary layer wind tunnel are used for validating the proposed approach.
