Definitions
- This invention makes it possible to increase the speed of rotation of the wind turbine, by adding to the usual wind pressure on the outside of the blades, the wind pressure inside the blades, causing a reaction at the outlet of the nozzles ( 5).
- the faster rotating wind turbine produces more work.
- Figure No. 1 shows the front outer face of a blade with here two inlet openings (4) for the wind.
