Orthogonal balanced low power wind turbine

On the base of analysis the problems of influence of outer impacts on wind turbines, the simplified approach of optimization of the turbine components was proposed. The solutions of substitution of curvilinear air foils by linear segments increased the aerodynamic quality of the profiles. The optimal number of blades is determined on the base of the required output power, rotation speed and inertial loading. It is stated that most efficient wind turbine should contain three blades with high features on low winds and self-starting ability. The design novelty is three tier turbine with 3 blades in each tier, where energy conversion part is based on toroid type fairing. The best quality of linking of traverses and joints was determined. Predictable vibrations of proposed components are calculated for exploitation and cut-off duties, which showed satisfactory results.
