MULTIPURPOSE TURBINE Russian patent published in 2001 - IPC

FIELD: conversion of energy of water flow or wind to energy of rotation of electric generator shaft. SUBSTANCE: turbine includes flexible shaft consisting of three cables and blades secured on this shaft; blades are made from two flexible linen circles fastened together in their central area forming one circle of two- layer cloth. Cloth has three rectilinear slots at angle of 120 deg. relative to one another from edge of circle towards its center by 3/4 of its radius forming six pairs of edges. Three alternating pairs of edges are fastened together by one layer of cloth above center of circle at distance of 1/2 of its radius forming angle unit and one side of wall. Other similar wall is formed on other side. Linen fairing having size sufficient for embracing pair of blades is secured to edges of three pairs of blades. Bushes fitted on turbine shaft on different sides of wall have length equal to 1/2 of radius of circle. Gently-sloping segment cuts are provided on outer edges of all blades near angles. Construction of turbine provides for rotation of shaft of electric generator in one direction at any direction of action of flow. EFFECT: enhanced efficiency. 4 dwg
