POWER PLANT TO CONVERT ENERGY OF AIR OR WATER FLOW CURRENTS

摘要

FIELD: power engineering.SUBSTANCE: power plant for conversion of energy of air or water flow currents comprises a power takeoff shaft, with which a wing 1 or an airfoil is connected kinematically via a movable axis and introduced into the flow along with its motion. The power takeoff shaft is arranged in the form of a crankshaft 5. The wing 1 or the airfoil is connected with the crankshaft 5 with a sling 4. Directly near the wing 1 the sling 4 has auxiliary rear and front slings with a function of attack angle limitation. The power plant comprises a device for control of the attack angle 2 from the minimum to the maximum level, made as capable of moving the spring-loaded axis relative to the centre of application of aerodynamic forces depending on direction of crankshaft 5 movement, and as a result from head of air or water medium.EFFECT: simplified design, reduced material intensity, increased manufacturability and lower specific cost of a generated kW*hr of electric energy.7 dwg
