20080203731 | Eolic converter - The present invention relates to an eolic converter endowed with a winds keeping system that allows an utilization of above 97% of the wind force to transform in mechanical rotational energy, at the same time that is added to this high efficiency the possibility to add several levels of plates without limit of size of the referred plates, what provides for an unique propeller shaft the use of gigantic areas of reception of the wind force where these shafts can be added in order to allow a great area of wind reception to rotate a shaft, even with low values of wind speed, this system doesn't need to be oriented for the wind direction, because traction independently of the moment wind direction, always rotating in the same direction that it was programmed to rotate. | 08-28-2008 |
20130039761 | VERTICAL WIND TURBINE WITH ARTICULATED BLADES - A vertical wind turbine to catch the wind force characterized by its system of aerodynamic panels are provided with blades fixed into horizontal axis that open and close simultaneously and symmetrically upward and downward due the gears like the butterfly wings rotated by 90° of its normal position, it is like opens an umbrella horizontally to receive on one side the wind buoyancy or pressure and in the other side close by the action of the wind. The top and bottom blades works as counterweight one to another both to open and close (flatness) which makes your weight null in relation to the effort of wind to open or close them independent of the self-weight of the blades what propitiate the maximum use of the wind force in the traction side without loss to the return of the blades to the traction position driving a vertical axis. | 02-14-2013 |
