Definitions

  • the present invention relates to an aerogenerator with a horizontal axis.
  • wind turbines have a rotor consisting of blades perpendicular to the transmission axis. These blades generate constraints that are:
  • the device according to the invention makes it possible to remedy these disadvantages or to reduce these constraints: 0 - operation by high wind and starting at low wind speed
  • the device according to the invention converts the kinetic energy of the wind into mechanical energy.
  • the mechanical energy of the rotor can be converted into electrical energy (coupling with an electric generator).
  • the invention can be exploited as a hydraulic turbine by immersing the rotor in a moving body of water. It can be exploited on a principle of driving tide or hydraulic power station.
  • the rotor blades can be composed in any type of materials (metals, composite, wood ).
  • the invention is an aerogenerator with a horizontal axis positioned in the direction of the wind and which consists of a rotor with semi-frustoconical blades twisted, almost parallel to the axis of rotation; a nacelle; a movable structure and a mast carrying the assembly 5 rotor / nacelle / mobile structure.
  • the rotor may consist of two, three or four blades and assembled on a transmission shaft or axis of rotation, (boards 1,2,3,4).
  • the top (the smallest side of the semi-trunk) B2 of diameter D2 is oriented around the axis
  • the blade has an angle of inclination ⁇ (psi) between 10 ° and 16 ° with respect to the axis of rotation of the rotor, (plate 6)
  • the rotor In the case where the rotor consists of three blades, the latter are oriented at an angle of 120 ° relative to each other (plate 2). The blade is fixed at two points to the drive shaft. Fixings are assured 50 by clamping on two hubs secured to the drive shaft (plate 7).
  • the flange at the level of the base Bl is fixed directly on the hub.
  • the flange at the base B2 is mechanically secured to the rear hub through a tabular stiffener.
  • the flaps are oriented to reduce the rotational speed of the rotor.
  • the rotor assembly is supported by two bearings at each end of the drive shaft (boards 2 and 3).
  • bearings are mechanically fixed on a mobile support structure in the shape of "U".
  • the mobile support structure is arranged on a mast.
  • An orientation system of the support structure / rotor assembly is disposed at the top of a mast.
  • the base of the mast is equipped with a base fixed on a massive concrete scrap.
