  • this and the wind deflector bodies can be pivoted about the axes mentioned, the rotor core body preferably being about the central axis and the wind deflector bodies being about the central axis of the semicircular cross sections forming the leading edge of the blades.
  • the support elements connecting the wind deflector bodies have cross dimensions as struts or closed flat elements which do not exceed the smaller transverse dimension of the rotor core body or essentially have this size, then the transport configuration can be carried out without any significant additional effort. wall are generated, since the cross struts form the end faces of the transport unit, so that in addition to locking devices, only a covering need be provided.

  • FIG. 2 shows the configuration and arrangement of the wind rotor bodies which are essential for the invention in a sectional view.
  • the rotor core body 7 only has outwardly curved wind deflecting surfaces 10a, b, each of which is assigned an outer wing body 8a, 8b with an essentially wing-shaped cross section.
  • the direction of rotation of the wind rotor 2 is indicated by the arrow direction shown. Regardless of the wind direction, the wind rotor 2 starts up from any position and immediately delivers energy that can be tapped at the terminals of the generator 6.
  • This wind rotor 2 to start up itself is based on the shape of the individual wind deflecting surfaces and the position of the wind rotor bodies 7 and 8a or 8b relative to one another during operation.
  • the air flowing through is deflected onto the outer wing body between the wing body 8a or 8b rotating in the wind and the rotor core body 7.
  • the speed of the air flowing past the wing body in question is thus significantly increased, so that an outward force occurs with a component in the direction of rotation.
  • FIG. 2 also shows the ratio and the form and mutual position of the wind deflecting surfaces of the wind rotor bodies in an embodiment with a pair of outer wing bodies.
  • the initial variable is the diameter D of the wind rotor 2.
  • the outer wind attack surfaces 11a, 11b of the wing bodies 8a, 8b are designed as cylinder jacket sections.

  • the inner wind deflecting surfaces 12a, 12b of the wing bodies 8a, 8b are flat surfaces. Together with the outer wind deflecting surfaces 11a, 11b, they each form the rear, acute-angled end of the wing bodies 8a, 8b, which lies on the radius of the wind rotor 2, which intersects the line of contact of the two wind deflecting surfaces 10a, 10b of the rotor core body 7.
  • These flat, inner wind deflecting surfaces 12a, 12b run in the 41 "direction to the connection: center of the wind rotor / wing body end and end in the front area of the wing bodies 8a, 8b at 49 ° to the connection: center of the wind rotor / end of the wing body.
  • the front wind deflecting surfaces 13a, 13b of a wing body 8a, 8b are likewise designed as cylinder jacket cuts formed, the radius of curvature corresponds to half the distance of the outer and inner wind deflecting surfaces 11a / 12a or 11b / 12b at the front end of the wing bodies 8a / 8b.
  • the wind deflecting surfaces 10a, 10b of the rotor core body 7 likewise form cylinder jacket sections. Their radius of curvature corresponds to the distance X of the center of curvature of the front wind deflecting surface 13a, 13b of the associated wing body 8a, 8b.
  • the respective center of curvature of the wind deflecting surfaces 10a, 10b is at a distance E from the center of the wind rotor 2, the 4.72th part of the diameter D being the wind rotor.
  • Wind rotor center / center of curvature of the front wind deflecting surface 13a, 13b of the associated wing body 8a, 8b removed. It is important - and this results from this design specification - that the tangents of two wind deflecting surfaces 10a, 10b form an angle of less than 90 ° in the plane of the drawing.
  • the specified dimensioning means that the "open" design, ie reduced rotor core or wing body cross section and the resulting higher speed, allow increased performance to be achieved.
  • the gearboxes and generators are also weight and space-saving, since the torques to be transmitted are reduced with higher speed and the same power, so that with some larger versions of the rotor there is also space inside the rotor core body.
  • the design according to the invention can advantageously be used not only in the case of smaller designs, but also in the case of larger designs.
  • the dimensioning according to the invention not only leads to an economically producible, but also to an easily transportable design.
  • Aluminum is preferably used as the material.
  • the figure shows the view of the end face, ie is seen from above or from below when the rotor is operational.
  • the wing bodies 8a and 8b can thus be fixed in a simple manner in their mutual position and their position relative to the rotating rotor core body 7 secured against any rotation.
  • Figure 3b shows the embodiment in the transport or stowage configuration, which is particularly advantageous when the wind rotor - for example on yachts - must be stored in a confined space.
  • wing bodies are pivoted in, the core body also being screwed into the surface area of the plate 14, the larger transverse dimension of which shows the connection between the rotor core body and wing elements and the smaller transverse dimension defines the height of the transport configuration.
  • the plates 14 are preferably selected to be smaller or equal to this transverse dimension in terms of their width (in the figure, the height).
  • the wing bodies are pivoted around in such a way that their inner boundary surfaces in the operational state come to lie on the outside and form parts of the outer surfaces of the transport configuration. It can be seen that the unit thus formed can also be shipped over long distances without difficulty can.
  • additional packaging can be used if an additional transport lock is provided, as shown in the figure.
  • This additional transport lock holds the outer wing bodies in the position shown, their pointed ends pointing to the rotor core body and limiting its pivotability. In this way, the core body only needs to be ne additional locking to be limited in its mobility.
  • the wing bodies are locked in their transport position in such a way that their surfaces lying outside in the operating state lie adjacent to the rotor body, then a further transport locking of the rotor body can be dispensed with become when it is only pivotable between its operating position and the transport position.
  • the pointed wing edge ends of the wing bodies hold the rotor core body in its corresponding position in the transport configuration.

Abstract

Une éolienne comprend un rotor rotatif autour d'un axe vertical, pourvu d'un corps à surfaces convexes de déviation du vent et d'aubes associées audit noyau. Le corps du rotor comprend des premières surfaces convexes de déviation du vent qui forment des sections d'une enveloppe cylindrique. Les aubes extérieures présentent une section transversale essentiellement en forme de surface portante dont l'extrémité en angle aigu, vue dans le sens de rotation du rotor, se situe sur le rayon du rotor, qui coupe l'interface entre deux surfaces de déviation du vent du corps du rotor. Le corps du rotor comprend deux surfaces de déviation du vent à symétrie inverse et une paire d'aubes extérieures. Des deuxièmes sections d'enveloppe cylindrique forment des surfaces extérieures planes et antérieures, vues dans le sens de rotation du rotor, de surfaces internes de déviation du vent d'une aube extérieure. Le rayon des premières sections de l'enveloppe cylindrique du corps (7) du rotor correspond au diamètre extérieur (D) de l'ensemble, déterminé par l'extension radiale maximale des aubes (82, 86) divisée par un premier facteur compris entre 3,3 et 3,6, notamment 3,45. L'excentricité du centre de courbure d'une section de l'enveloppe cylindrique du corps (7) correspond au diamètre extérieur (D) de l'ensemble divisé par un deuxième facteur compris entre 4,5 et 5, de préférence 4,72.
