FIELD: power industry.
SUBSTANCE: at end faces of the top and bottom sections of the main blade from the side of the running flow the rotary flaps of a flowline shape are placed, which are withheld within the limiting angles by the springing forks and returnable springs with adjustable tension are located in addition on trailer pins. Hollow sections of the main blade are in addition strengthened inside by corrugated stiffening ribs, especially in places of contact with the damping overlays of springing forks. The invention promotes creation of new types of environmentally friendly and low-noise wind- and submersible hydroelectric power plants.
EFFECT: improvement of efficiency of rotation of blades in extreme left and right positions, improvement of spontaneous start of the console after its stop during a storm or scheduled maintenance.
