Abstract
The invention relates to a wind power plant, comprising a rotor that can be rotated about a vertical axis, said rotor between two horizontal bearing planes disposed at a distance on top of each other comprising a plurality of rotor blades, which are disposed distributed on a circumferential circle, can each be pivoted about a vertical pivot axis, and the pivot range of which is delimited on both sides by a stop. In such a wind power plant, an improvement in the energy yield, while simultaneously ensuring another operation, is enabled in that the width of the rotor blades is smaller than approximately ⅓ the radius of the circumferential circle.

A wind power installation comprising:
- at least one rotor which can rotate about a vertical axis and, between two horizontal mounting planes, which are located one above the other and separated, a plurality of rotor blades, which are arranged distributed on a circumferential circle and can each pivot about a vertical pivoting axis extending between said two horizontal mounting planes, and whose pivoting range is bounded at both ends by a single stop, wherein the width of the rotor blades is less than ⅓ of the radius of the circumferential circle, whereby said mounting planes are formed by wheels which rotate about said vertical axis, and the at least one rotor is connected via a shaft to a generator unit.
A wind power installation comprising:
- at least one rotor which can rotate about a vertical axis and, between two horizontal mounting planes, which are located one above the other and separated,
- a plurality of rotor blades, which are arranged distributed on a circumferential circle and can each pivot about a vertical pivoting axis extending between said two horizontal mounting planes, and whose pivoting range is bounded at both ends by a stop,
- wherein the rotor blades are in the form of straight blades;
- the rotor blades each have a leading edge and a trailing edge, and have a reduced thickness between the leading edge and the trailing edge;
- the width of the rotor blades is less than ⅓ of the radius of the circumferential circle;
- said mounting planes are formed by wheels which rotate about said vertical axis,
- the at least one rotor is connected via a shaft to a generator unit;
