The analysis of structure of horizontal-axis wind turbine with sail-blades is carried out. Its operational features are overviewed. The technique of experiment replication is developed. The scopes of further investigations are presented.
Wind energy is considered as one of the most perspective, developed and ecologically clean energy resource. Nevertheless, it is associated with several harmful factors which influence environment. That’s why basic causes and zones of vibration initiation in wind turbines, as well as negative vibratory and acoustic factors of wind turbine influence on natural beings, are analyzed.
The necessity of further improving of existent regulation mechanisms is motivated for the purpose of increasing of accuracy of power regulation, effectiveness and reliability of wind turbines functioning in wide range of wind speeds. The prospects of creation of combined mechanical systems are considered, where the possibilities of simultaneous blades turning and folding, blades turning (or folding) and wind-wheel deflection out of wind direction are provided.
