Abstract

The turbine system for wind and / or water power, wherein the radial turbines have a rotor which can rotate about an axis and comprises one or more turbine blades, wherein the turbine blades are aligned parallel to the rotor, wherein the turbine blades are arranged within a cylindrical shell, which is arranged concentrically around the axis and has an outer radius R1 and an inner radius R2, is characterized in that the turbine blades have a specific geometry and in that two radial turbines (1, 2) which are aligned alongside one another and parallel are arranged, which radial turbines (1, 2) are connected to one another and can pivot about a pivoting axis (15) parallel to the turbine axes (18), wherein the pivoting axis and the guide surfaces (3, 4) are not located on the connecting line between the turbine axes, and are both located on the same side of the connecting line. It is proposed that the abstract be published without any drawing.

Description

technical field [0001] The invention relates to a turbine system according to the preamble of claim 1 . Background technique [0002] Savonius turbines are known (see also Figure 6 ). These rotors may comprise two horizontal discs attached to a vertical rotor shaft and between the two discs two semicircular curved blades are attached in a vertical position. [0003] Even when the weight distribution is perfectly balanced, a decisive imbalance during rotation due to cyclically varying load intensities from the flow is characteristic of Savonius rotors. This unbalance due to load alternation can be minimized by arranging a greater number of blades, typically three instead of two. However, this significantly reduces the efficiency of the Savonius rotor by approximately 30%. [0004] Compared to known three-blade wind generators with a horizontal axis of rotation and aircraft-type blades, radial turbines have the major advantage of operating independently of the incoming win...
