On the other side ofthe rotor, angular velocity orientation affects the gyroscopic,inertial and other loadings in the blade, in accordance, determinesthe lifetime of the blade and wind turbine as a whole.Today the mathematical models of the orientation systemsof the rotor in the direction of air flow, taking into account anumber of parameters and system performance orientation of therotor. It is necessary to take into account the continuousimprovement of designs of wind turbines rotor orientation,which requires amending the already proven mathematicalmodels of wind turbines rotor orientation, and some assumptionsin making mathematical models can dramatically change thepicture of the physical process.In this paper an improved mathematical model basedorientation rotor gyroscopic torque that occurs during orientationof the rotor in the direction of air flow. This mathematical modelallows obtaining an equation for calculating the velocity of theorientation of the rotor depending on the wind speeds, the angleof deflection of the rotor from the direction of air flow and anumber of system design parameters orientation of the rotor,which in turn allows to identify energy losses and gyroscopicloads on structural elements of wind turbines in the processorientation rotor.
