This jet turbine has almost 2 times more power than existing turbines with the same dimensions.
The turbine differs that has two additional elements - a turbo-expander in the center and jet cuts on blades.
The turbo expander absorbs wind energy. Thus the non-working center of the turbine becomes effective.
Blades of the turbine have cuts which open cavities inside the blades. The stream of air comes inside the blade and presses inside too.
Thus the area of pressure of a wind increases almost in 2 times without change of a configuration of the blade.
The wind presses on the middle and top surface simultaneously from within.
Accordingly the capacity of the turbine increases maximum in 2 times too, minimum on 50 % depending on a configuration of the blades.
Rigidity of the blade does not decrease thus. Longerons and ribs provide stability of the blade and reduce its weight.
The baldes have the second cut on the bottom part and an additional plane inside. The stream of air or water will come through the top cut, then it will pass around of a plane and will be squeezed out through cuts from other surface of the blade.
This jet stream will increase capacity of the turbine even more as pressure and the jet moment will be summarized.
Turboexpander in the center increases power even more.
Similar studies have been conducted with a hemisphere called ecoRotr.
Experiments have shown that the hemisphere in the center of the turbine increases power by 3%.
If this is so, then turboexpander will increase turbine capacity by 10-15%.
This turbine has received the diploma of Energy Globe.
