MECHANISM OF TURBINE BLADE TRANSFORMATION Russian patent published in 2015 - IPC F03D7/06 

FIELD: machine building.

SUBSTANCE: mechanism of turbine blade transformation contains basic part of the blade installed on the turbine rotor with possibility of rotation relatively to the vertical axis between the mechanical limiters. Link of the basic part of the blade and flap contains first toothed segment rigidly secured on the rotor coaxially with axis of rotation of the basic part of the blade, second toothed segment secured to the flap coaxially with its geometrical axis, and third toothed segment installed on the basic part of the blade between the first and second toothed segments engaged with them, with possibility of rotation relatively to the vertical axis passing through chord of the basic part of the blade.

EFFECT: each blade is made out of two rigid parts connected by mechanism of coordinated rotation, and upon free rotation of the blades under wind action their geometry varies according to angle of rotation relatively to the rotor casing and wind force ensuring optimal convex-concave airfoil, and hence increasing of the traction characteristics of the wind motor.
