Vertical rotor (wind energy converter) having two or more vertical blades, on the outside of which there are mounted folding blades which are in the shape of a half-shell and which, when all opened out, produce an upright, circular rotor body which is closed on the outside. Being rotatably mounted on one side, the folding blades mounted on the blades of the rotor automatically open on the side of the rotor receiving the wind and automatically close on the other side of the rotor, facing away from the wind. The folding blades, which are situated approximately opposite one another in pairs, are connected to one another by means of cable bracings, the length of cable determining the possible opening-out angle of the other folding blade. The cable bracings, which in each case connect two folding blades, are horizontally guided through the axial region of the rotor on deflection rollers, and, when raised here, can bring about a horizontally effective shortening of the cable leading to the open folding blade in each case, ie. leading to a reduction in the opening-out angle of the said folding blade. As a result of the fact that the folding blades are opened by the wind on the side of the rotor which receives the wind and are closed by it on the side of the rotor facing away from the wind, excellent wind resistance values which are compatible with rotation are yielded by a concave, wind-receiving side of the rotor and a convex side of the rotor facing away from the wind. The rotary energy delivered by the rotor can be set to predetermined ranges of wind speed by means of a wind flap control system ... Original abstract incomplete.
