Definitions

  • the present invention relates to renewable energy sources, and in particular to the use of moving air masses (wind) to generate energy, in particular electric, as well as small hydroelectric power stations.
  • the main problem is the extensive zone of turbulent eddies spreading behind the generator. This does not allow them to be placed close to each other.
  • Another advantage is the modular design and the ability to add and connect the required number of modules in case of increased demand for electricity.
  • Bladeless wind generator Another example of a bladeless wind generator is the development of the American company Solar Aero Research (called “Fuller Wind Turbine” by the name of the president of Fuller).
  • Tesla turbine invented in 1913, which was created to generate energy from steam or compressed air, and Fuller adapted a long-standing idea to "tame" wind energy.
  • Tesla’s turbine is a set of many thin metal disks separated by small gaps, the flow of working fluid or gas flows from the outer edge of the disks and passes through the gaps to the center, 5 spinning and dragging the discs themselves due to the effect of the boundary layer. In the center, the flow exits through the axial hole.
  • the objective of the present invention is to provide a wind power installation, which would have the following advantages over the known.
  • the invention is based on a new principle - the construction of a wind power plant based on an aerodynamic surface in the form of a wing.
  • a “wing” is understood to mean an aerodynamic surface, usually intended to create a lift in aircraft due to the difference in the area of one part of the surface relative to the other 15 (upper and lower relative to the ground) and, as a result, due to differences in the speeds and pressures of the air flows flowing around the indicated parts of the wing.
  • it is proposed to connect said parts of the wing surface with an air channel. Due to the pressure difference, part of the air flow enveloping part of the surface of the wing of a smaller area will be sucked into this channel and used to rotate the turbine leading the electric generator.
  • the lifting force acting on the wing allows it to be held in the air without the need for special structures. However, this does not exclude the possibility of fixing the wing on a special structure, such as a tower, support.
  • a flexible connection in particular, a cable attached at one end to a wing and the other to a holding device fixed to the ground, can be used as one of the options for “holding” a wind power installation above the ground.
  • the specified cable can be used to attach a cable to it for the sewage of electrical energy to the ground.
  • the wing and the installation as a whole can be made mobile, in particular mounted on a vehicle moving on land or on water, while the wing can be or is connected with such means by flexible connection.
  • Another embodiment of the invention is the use of an aircraft wing, for example, a glider, as an aerodynamic surface, providing not only its flight, but also the generation of electricity by performing in the aircraft wing a channel connecting the upper and lower surface of the wing, which has fluid communication with generator turbine. Electricity consumers in this case can be located directly on aircraft, including the possibility of accumulating electricity in traditional batteries.
  • the wing according to the invention can be arranged not only horizontally or essentially horizontally, but also vertically or essentially vertically. This is advisable in the case of the presence of ascending air flows, for example, in vertical pipelines. It can also be located in tunnels and mounted on its walls or ceiling.
  • the principle underlying this invention is also implemented in the case of placing the wing in a water stream, that is, in an embodiment of the invention as a hydropower installation.
  • Fig. 3 the same in the embodiment of the wing with several air ducts and turbines;
  • Fig. 4 view of the wing from the side of part of its surface of a larger area
  • Fig. 5 view of the wing from the side of part of its surface of a smaller area
  • Fig.6 an option of the installation location on the support
  • Fig. 9 is an embodiment of the installation of a mobile towed vehicle;
  • Fig. 10 - an option of fixing aerodynamic surfaces in the tunnel;
  • Fig. 11 is an embodiment of a wing with an adjustable flap.
  • Fig. 13 - shows one of the options for placing the wing of a hydropower plant in a floating state.
  • the wind power installation includes: an aerodynamic surface in the form of a wing (1) in the body of which at least one channel (2) is made connecting a part of the surface of the wing (3) of a smaller area with a part of the surface of the wing (4) of a larger area, a turbine (5) driven into rotation by the air flow generated in said channel (2), an electric generator (6) driven by a turbine (5), means of electrical energy drainage from the generator to consumers (not shown), and aerodynamic holding means surface (wing 1) at a certain height above the ground, in particular, in the form of a support (7).
  • the principle of operation of the installation is as follows.
  • the wing (1) is oriented frontally relative to the direction of movement of the air masses of the wind. As noted above, such tools are traditional for wind generators and therefore are not described here. Due to the difference in the area of the parts (3) and (4) of the wing, the air pressure on the part (3) of the smaller area is greater than the pressure on the part (4) of the larger area, as a result of which air is drawn into the channel (2) connecting these parts of the wing.
  • the air stream formed in the channel drives the turbine (5) located on its path and, accordingly, the generator (6) through the turbine.
  • the wing (1) can be located not only in an open area, but also “in an enclosed space”, in particular in pipelines, for example in ventilation shafts in which air moves or in tunnels (10). Accordingly, the position of the wing (1) may be different. In an open area, where the winds blow substantially parallel to the surface of the earth, the wing will be located essentially horizontally, while part (3) of a smaller area will face the ground, and part (4) of a larger area will be facing the ground.
  • the orientation of the wing When installed in the pipeline, the orientation of the wing will be determined by the orientation of the pipeline, if the pipeline and, accordingly, the air flow in it is located vertically, then the wing (its longitudinal axis) will be oriented essentially vertically.
  • a variation of this arrangement of the installation is its placement in the tunnels (figure 10).
  • the vertical or essentially vertical position of the wing cannot be excluded when using the installation in an open area, for example, in a mountainous area characterized by ascending air currents.
  • the installation according to the invention can be made mobile.
  • such a design may be appropriate when the wind is low, when the vehicle speed is added to its speed.
  • FIG. 9 Such an embodiment of the invention is shown schematically in FIG. 9, where item 8 is a vehicle and item 9 is a flexible element (cable) connecting the vehicle and the wing (1). It is advisable to use the cable for attaching an electric cable (not shown).
  • the vehicle may be land-based or floating and, finally, be an aircraft, for example, a glider, or a hang glider towing a wing (1).
  • An extreme case of this design is the combination of the aerodynamic surface of the wind power installation and the wing of the aircraft, that is, the execution directly in the wing of the aircraft of the channel (2) and the placement of a turbine (5) that drives an electric generator.
  • the consumers of energy are the means of ensuring the flight of the aircraft and, again, the batteries.
  • the described installation can be multiplied, firstly, by performing several air ducts in the wing (see FIG. 3), and secondly, by using several aerodynamic surfaces (see Figs. 7 and 8).
  • the embodiment of the installation with a rotatable adjustable flap (I) allows the rotation of the flap to change the ratio of the areas of the parts (3) and (4) of the wing and, as a result, to regulate the lifting force of the wing and the speed of air flow in the channel (2), and therefore, the power provided by the electric generator 6. This is also facilitated by the drag against the air flow provided by the flap when it is turned to the position shown in Fig. 12.
  • One of the embodiments of the invention is the option of placing the wing described above under water in a water stream (in a river, stream, canal) using the same wing structure (see Figs. 13 and 14).
  • the difference in the areas of the wing parts located opposite to the part of its axis creates a pressure difference between the water on this surface, which ensures the "forcing" of water from one part of the surface ("high” pressure) to another part of the surface through a channel (2) that directs water to the turbine blades (5).
  • the wing (or wings) can be fixed on a support (Fig. 14) or held in a floating state by flexible elements fixed to the bottom of the pond.
  • the wing can also be attached to a moving vessel, and in this case, it can be held in a submerged position using ballast placed on it.
  • the "flying" version of the installation allows you to place the wing at heights with high wind speeds, which improves its efficiency.
  • An embodiment based on the same principle of a hydropower installation allows providing electricity to consumers in places where the use of water resources is economically preferable to using wind.
