Definitions

  • This invention is related to the field of wind power, specifically belonging to wind turbines with a cylinder rotor.
  • the wind generator is placed directly on the surface of the earth
  • This turbine has the following shortcomings:
  • the back rotor nacelle creates a large resistance to the airflow.
  • the rotor and nacelle become windproof almost like a flat hard obstacle with a small opening at the bottom. According to Figures 1 and 2 the width of this opening is equal to a maximum 1.5 times the width of the rotor blade; therefore, this structure has a low efficiency.
  • the rotor works at 1.5 times the load of the blade.
  • the remaining airflow bypasses the structure of the wind generator;
  • the wind generator is placed on the surface of the earth, which reduces its effectiveness, because of the numerous obstacles (buildings, forest) the velocity of the wind there is lower than that above.
  • a pole would be required, the manufacturing of which would require a large amount of materials;
  • the structure of the wind baffle, wind receiver and vane compared to the functions they perform is not rational and consumes a large amount of materials.
  • the wind generator is placed directly on the surface of the earth
  • This turbine is characterised not only by the same shortcomings as the one described above, but also by several additional ones:
  • the wind generator is often oriented downwind in an unstable manner, as it will swing at an amplitude of approximately 50°;
  • the vane is also placed on the ground, which prevents the placement of the wind generator above the ground.
  • this structure will be unable to operate.
  • the passage for the direct airflow is closed and it cannot return against itself.
  • the wind will have to flow through the structure of the wind generator as through a continuous obstacle similar to that of a wall (See Fig. 1A).
  • This structure has the following shortcomings:
  • the wind baffle battles with the vane creating the axel weight and poorly performs its second designated purpose - the release of the airflow onto the rotor blade.
  • Blades complicate the rotor structure, as well as its price; they also do not increase the rotation moment in comparison to the probable distribution of the rotor blades.
  • the ratio of the blade width in respect to the rotor diameter is 1/3; in addition, their number and form are optimal.
  • the wind vane is placed in the wind shadow of the rotor and moved to the opposite side of the wind baffle.
  • This structure has the following shortcomings:
  • the purpose of the invention is to create a highly efficient wind generator characterised by reliable construction and operating in a wide range of wind velocities.
  • the wind turbine with a cylinder rotor and wind deflecting device which includes the wind receiver, wind baffle and vane mantled on a rotating axle, is characterised by the fact that the rotor can have from 2 to 10 blades given the following ratio of the sizes of the elements:
  • the ratio of the width of the blade to its length is: 1:4 - 1 :8;
  • angles yand ⁇ correspondingly comprise 0° - 28° and 20° - 45°;
  • the wind turbine is also characterised by the fact that the sizes and positions of the wind receiver, wind baffle and wind vane are interrelated and their calculation is subject to the size of the rotor and the established average annual wind velocity in a particular region.
  • the curve of a cross-section of the blade must correspond to the minimum air resistance at the moment of motion with its arched section forward.
  • the wind turbine has top and bottom wings Ri and R 2 with the following measurements:
  • the width of the wing is equal to 0.4 - 0.8 of the width of the rotor blade, the length of the wing is equal to 1 ⁇ 2 times the width of the rotor blade.
  • the wings are placed on the active back part of the rotor and can be asymmetrical in relation to the vane axle.
  • the wind turbine is additionally characterised by having the vane constructed in a way that enables it to rotate in the planar and perpendicular motion in relation to the rotation axis and in the position parallel to the rotation axis.
  • Fig. 1 - depicts the schemes of the wind generator with a cylinder rotor of an existing technical level.
  • Fig. 2 - depicts the wind generator with a cylinder rotor indicating the scheme of the wind flow.
  • Fig. 3 - depicts the wind generator with a cylinder rotor including the scheme of the established measurements of the lines.

  • the ratio of the width of the blade (marked with a letter B in Fig. 2-4) to its length is approximately equal to 1/4.
  • the ratio of the width of blade B to the rotor diameter is approximately equal to 1/3.
