METHOD TO CONVERT ENERGY OF AIR OR WATER FLOW CURRENTS AND POWER PLANT FOR ITS REALISATION Russian patent published in 2013 - IPC F03D5/06 F03B17/06 B63H1/36 

FIELD: power engineering.

SUBSTANCE: method for conversion of energy of air or water flow currents is characterised by usage of a spring 8, with which a wing 1 or an airfoil is connected kinematically via a movable axis. The wing 1 or the airfoil is connected with the spring 8 with a sling 4. Directly near the wing 1 the sling 4 is equipped with auxiliary rear and front bridles 5 and 6. The bridles 5 and 6 limit the attack angle from the minimum to the maximum position by means of movement of the axis relative to the centre of forces application, creating a torque, which in its turn results in change of the attack angle and sling 4 tension.

EFFECT: simplified design, reduced material intensity, increased manufacturability and as a result lower specific cost of a generated kW*hr of electric energy.
