Abstract On the basis of the aerodynamic model of the screw, studies of the interaction of the rotor, the ring and the output device of the wind power plant of the "rotor in the bell" arrangement were carried out. Compiled a functional diagram of the process of the study of aerodynamics and mathematical models of the wind turbine (WU). To improve the efficiency of use of wind power and aerodynamic power. but the simulation of the aerodynamics of the socket of the propeller in the program of kom-Plex Ansys Workbench and Ansys Fluent. In a given range of wind loads and a given rotor, the optimal shape of the bell is obtained, providing the maximum average value of the useful aerodynamic power (P) of the wind flow of the rotor. The optimization according to a given criterion and a given set of basic shapes of the geometry of the bell of the wind power plant of the "rotor in the raster" type is carried out. The aerodynamic load on the rotor for the optimal shape of the wind turbine bell is investigated. The characteristic distributions of scalar and vector fields illustrating the flow pattern of the considered system "rotor+bell" are considered for the given parameters of the undisturbed flow and rotation of the rotor. The graphs of the moment dependences (Mz, My, Mx) of the standard, optimized WU form on the linear velocity of the incoming flow are obtained, as well as the dependence of the Aero-dynamic powers of the standard and optimized form on the velocity of the incoming flow. Presents the results of aerodynamic optimization veteraner-energy installation (wind turbines) with a vertical axis of rotation, assymmetric-governmental stator and rotor, and special shapes. It is shown that the wind turbines using the useful interference of the stator and rotor exceed the classical wind turbines in terms of energy characteristics, all other things being equal. Determined the future development of wind turbines which consists in the use of mutable elements of geometry improves the adaptability of the control system, expanding the control range of the torque on the rotor, but also of the robustness of the characteristics of wind and structural perturbations.
