The effects of a steady wind with vertical shear flowing into a horizontal axis wind turbine rotor have been analysed concerning about a velocity field in the rotor plane and aerodynamic loads on the rotor blades, by performing numerical calculations. The vertical gradient in the wind speed profile, that is, the wind shear, brings about an asymmetric flow field about the vertical direction in the rotor plane, so that the relative velocity to the rotating blade shows unsteadiness and the aerodynamic loads experienced by the blade have cyclic fluctuations. For the present calculation, an inviscid aerodynamic model is used, which is based on an asymptotic acceleration potential method. In the calculation model, the rotor blades are represented by spanwise and chordwise pressure distributions, which satisfy the Laplace equation.
