Cross-talk compensation for blade root flap-and edgewise moments on an experimental research wind turbine and comparison to numerical results

• In the current paper a method to correct cross-talk effects for strain-gauge measurements is presented. Themethod is demonstrated on an experimental horizontal axiswind turbine. The procedure takes cross-moments (flapwise on edgewise moments and vice versa) as well as axialacceleration into account. The results from the experimental setup are compared to numerical URANS calculationsand the medium-fidelity code Qblade for a baseline caseand two yawed inflow situations.
