horizontal-axis wind turbine

Different constructions of inertial mechanisms of blades folding of horizontal-axis wind turbines are considered in the article. Their structural analysis is held and analytical dependencies for calculation kinematical parameters of the mechanisms are presented. Based on the kinematical analysis data the influence of different geometrical parameters on changing of blades position angle and displacement of regulation sliders is investigated. The features of calculation of construction parameters of inertial mechanisms of blades folding of horizontal- axis wind turbines are analyzed.

The expediency of alternative energy sources implementation in Ukrainian industry and agriculture is substantiated. Much attention is focused on the possibilities of the wind turbines using on the territory of our country. Main problems of the modern wind-electric turbines exploitation are considered. The construction of the low-speed (multiblade) horizontal-axis wind-wheel with sail-blades is proposed and the parameters of its basic elements (blades, wind- wheel hub, mechanism of blades attachment, etc.). are calculated.

Various types of combined mechanisms of simultaneous blades turning and folding, which can be used for power regulation and rotation frequency stabilization of horizontal-axis wind turbines, are examined. Kinematic diagrams of certain mechanisms are designed. Analytical expressions for ascertainment of regulation sliders displacements from turning and folding angles are deduced.
