Wind turbine type hyperboloid Shukhov
Wind turbine type hyperboloid Shukhov.
Wind turbine type hyperboloid Shukhov is able to operate even in the updrafts of air that takes place, usually next to a river, lake, swamp, on the slopes of hills and ravines. The conditions “self-suction” and “self support”, as in the helicoid turbines, although it does not play a decisive role in the work.
The technology is awaiting funding and is in the process of development!
Comparison of the characteristics of
Based on the wind turbine type on hyperboloid Shukhov laid ideas of the great Russian engineer and scientist Shukhov V. G.
In the figure, the working area of the wind flow colored in red. With this parameter it (wind turbine type hyperboloid Shukhov) is superior to other types of turbines, namely: the working area of the wind flow-type impeller is 7-8% of the sweeping area; turbine Darrieus and Savonius – 45-50%; in this case, 60-70%.
Wind turbines of this type can operate even in the updrafts of airthat takes place, usually next to a river, lake, swamp, on the slopes of hills and ravines.
The conditions “self-suction” and “self support”, as in the helicoid turbines, although it does not play a decisive role in the work.
– the line of contact of the active layer of the air flow around a hyperboloid, 1.6 times longer than the same line of the rotating cylinder of the rotary type wind turbine with straight blades. It is natural to expect that the efficiency of wind turbines will be higher in proportion to this value
– constructive device of the working body in combination with the ease, strength and balance allows the installation units (gearbox, generator , etc.) to place inside the built-in volume, which reduces the size and weight of the entire installation as a whole,
– the total moment of inertia of the structure is defined as the sum of the products of the masses of material points on the value of the square of the length of the radius. On this basis, it follows that the moment of inertia of the rest of the design, at least half the moment of inertia of a rotating cylinder of wind turbines with straight blades, and, therefore, required the force of the wind at the time of breakaway in half.
