main bearing is extended by relieving the main bearing by reducing the mean bending moment on the bearing by means of individual pitch control of the blades of the rotor so as to create an aerodynamic mean tilt moment on the rotor by means of aerodynamic forces on the blades the tilt moment at least partly counteracting the bending moment caused by the overhang load forces on the main bearing from the gravitational pull on the rotor mass application_number US 57084609 A description in the following is disclosed an example of implementation of the present invention for reducing the mean bending moment on the main bearing of a wind turbine having a pitch control arrangement of the cyclic pitch type which uses a higher order simulation of the blade loads to reduce fatigue of the blades fig1 illustrates a modern wind turbine 1 with a tower 2 and a wind turbine nacelle 3 positioned on top of the tower the wind turbine rotor comprising at least one blade such as three wind turbine blades 5 as illustrated is connected to the hub 4 through pitch mechanisms 16 each pitch mechanism includes a blade bearing and pitch actuating means which allows the blade to pitch in relation to the wind the pitching of the blades is controlled for each blade of the rotor by a pitch controller operating with a higher order cyclic pitch control as will be further explained below the blades 5 of the wind turbine rotor are connected to the nacelle through the low speed shaft 4 which extends out of the nacelle front as illustrated in the figure wind.
