Owing to flexibility of blades, turbine moves always in one direction. Chords of blades at rest are located in plane of turbine rotation, and in active state, blades flex like wing of bird or tail of fish at stroke cross to direction of motion. Gripping of blade and power action from float to blade is provided according to rule U=0.29 in direction cross to plane of blade motion. Blades are arranged in pairs symmetrically relative to rotating shaft on crossmember to form separate element of turbine with torques of same signs for both blades number. Of such elements arranged along turbine rotating shaft determines power of turbine rising in proportion of number of turbine elements whose relative arrangement in angle of plane of rotation and element-to-element distance of rotating shaft is determined to provide maximum efficiency of elements in operation.
