Definitions
- the invention relates to a rotor blade for a Darrieus rotor in H-construction for a wind turbine.
- a Darrieus rotor is a wind turbine by which kinetic energy of the air flowing as wind is converted into kinetic energy of a rotor, wherein the axis of rotation of the rotor is substantially normal to the direction of flow of the wind.
- Wind turbines with a Darrieus rotor are inexpensive and robust and especially for small plants, which can be placed, for example, on building roofs, advantageous because they work well even with frequently changing wind directions.
- In the H-construction of a Darrieus rotor two at least approximately in the vertical direction extending rotor blades are connected and held together by at least one connecting strut.
- the connecting strut is rotatably mounted about a vertical axis in its longitudinal center.
- a typical in the essential areas of construction for a wind turbine with Darrieus rotor in H-construction is shown in DE 20 2007 010 873 Ul.
- the profile cross-sectional shape of a lance rotor blade which is normal to the axis of rotation is approximately equal to an airfoil profile.
- Darrieus rotors tend to vibrate, that they require a relatively strong wind to start and that they can cause strong noises.
- the object underlying the invention is to provide a rotor blade for a Darrieus rotor in H-type, which is improved in terms of noise and start-up characteristics over known designs.
- the upper and lower ends of the rotor blades with respect to the remaining rotor blade slightly bent away from the rotor axis outwardly form and the o- beren and lower part of the leading edge of the rotor blades in the direction of operational movement relative to the central part of the Curve the leading edge slightly to the rear.
- Fig. 1 shows an exemplary Darrieus rotor in oblique view.
- Fig. 2 shows a rotor blade of the rotor of Fig. L, wherein the viewing direction is equal to the direction of movement of the rotor blade, which rotates about a left of the rotor blade arranged, vertical axis.
- Fig. 3 shows a rotor blade of the rotor of Fig. 1, wherein the viewing direction is directed radially to the rotor axis.
