METHOD TO CONVERT ENERGY OF AIR OR WATER FLOW CURRENTS

摘要

FIELD: power engineering.SUBSTANCE: method to convert energy of air or water flow currents is characterised by using of a power takeoff shaft, with which a wing 1 or an airfoil is kinematically connected via a movable axis being introduced into the flow along with its movement. 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 using a sling 4, equipped with additional short slings in close proximity of the wing. Slings provide for limitation of the attack angle of the wing 1 in the specified range. With the help of the device to control the attack angle 2 the attack angle of the wing 1 is changed with a jump from the minimum one to the maximum one, moving with the help of the movable mass of the accelerometer rigidly connected with a cam the axis of the main sling relative to the centre of application of aerodynamic forces depending on the direction of the crankshaft 5 motion.EFFECT: simplified design of a converter realised on the basis of the method, reduced metal intensity, higher manufacturability and as a result reduction of specific cost of a produced kW hour of power.7 dwg
