1. the rotor blade of a wind energy facility, in service at described wind energy facility, described rotorthe inclination angle of blade is variable,described rotor blade comprises:

  • Rotor blade root;

    The rotor blade tip;

    AndMainboard, its between described rotor blade root and described rotor blade tip,Wherein, the configuration of the mainboard of described rotor blade is configured to;

    the optimum inclination angle at the mainboard from described rotor blade departs from ±

    scope of 2 °

    in, the ratio of lift coefficient to drag coefficient of the mainboard that the value of ratio of lift coefficient to drag coefficient is described rotor blade peaked more than 80%.
