Abstract
The invention relates to a wind wheel (1) for a low-speed wind power installation, comprising a plurality of rotor blades (2). In order to use said wind wheel during weak and gusty winds, the wind wheel (1) comprises at least one acceleration ring (3) connecting the rotor blades (2), for air acceleration in the normal direction in relation to the plane of the wind wheel (1).

-15. (canceled)
A wind wheel for a low-speed wind power plant, comprising:
- multiple rotor blades;
- and
- at least two acceleration rings connecting the rotor blades for air acceleration in a direction perpendicular to a plane of the wind wheel, each said acceleration ring comprising first and second guiding elements spaced apart from one another in a radial direction of the wind wheel and forming an air passage in the direction perpendicular to the plane of the wind wheel,
- wherein one of the acceleration rings is arranged essentially on an outer edge of the wind wheel to define an external acceleration ring, and the other one of the acceleration rings defines an internal acceleration ring disposed to interrupt the rotor blades.
