Embodiment Construction

[0039] figure 1 A wind turbine rotor of the present invention and its details are shown. In order to understand the advantages and functions of this wind turbine rotor, Figure 4 shows the embodiment of the wind turbine rotor in the installed state, based on Figure 4 Its general function is described. The wind turbine rotor comprises a hub 2 rotatably supported on a nacelle 1 . The hub 2 is rotatable such that the axis of rotation of the hub 2 is substantially horizontally aligned. The axis of rotation can be slightly inclined such that the direction of extension of the axis of rotation against the wind direction is slightly upwardly inclined. Such deviations shall be considered to be included within the meaning of horizontal alignment of the axes. In addition, the front side of the hub 2 faces the wind so that the wind flows directly towards the hub 2 . In order to reduce disturbances caused by wind flow passing over the surface of the hub 2, the hub 2 is formed with a...

Abstract

A wind turbine rotor is provided which comprises a hub (2) and at least one blade (20) supported by said hub (2). The blade (20) comprises a first blade section (3) and a second blade section (4), wherein said first blade section (3) is mounted to said hub (2) stationary with respect to said hub (2) and said second blade section (4) is supported by said first blade section (3) rotatably adjustable about a longitudinal axis of said blade (20) wherein said second blade section (4) is supported by said first blade section (3) by at least two bearings (7a, 7b) which are spaced with respect to said longitudinal axis of said blade (20).

Description

technical field [0001] The invention relates to a wind turbine rotor and a wind turbine comprising such a wind turbine rotor. Background technique [0002] In one known wind turbine, a plurality of blades are mounted to a hub which is connected to a generator system for generating electrical power, wherein the generator system is based on rotational power produced by wind energy exerted on the blades. In known wind turbine installations, the hub is mounted rotatably with its axis substantially horizontally aligned, wherein the installation is referred to as a horizontal wind turbine. In such known horizontal wind turbines, a wind turbine rotor is used in which the blade pitch angle can be adjusted such that a predetermined rotational speed is obtained depending on the specific wind conditions. [0003] In recent years, the length of wind turbine blades has increased in order for wind turbine installations to have an output of as much as 1 MW(EL) or more in a single turbine....
