Thrust and wake of a wind turbine: Relationship and measurements

1 Introduction The thrust is the axial force applied by the wind on the rotor of a wind turbine. Because all action yields an opposite reaction, the thrust is therefore also the axial force applied by the wind turbine on the wind. While the power output of a wind turbine
