Abstract

The device has a shroud provided in form of a conical corolla (1) that includes an inlet opening (4) and an exhaust bottleneck (3) in which a propeller (2) of a wind turbine is to be positioned, so that wind engulfing into the inlet opening of the corolla is provided with accelerated speed by conicity of the corolla. The propeller is actuated according to a square law of speed. The corolla is actuated in a direction of the wind by rotating the corolla on its axis (5) by a rudder (6) according to a principle of wind vanes.

Description

DESCRIPTION 1- Actuellement, les éoliennes se présentes nues face aux vents sans qu'aucun dispositif ne vienne améliorer leur rendement. L'invention se présente sous la forme d'une corolle (1) dans laquelle l'hélice (2) vient se loger tout au fond, dans le goulet d'échappement (3). 5- Le vent s'engouffre dans la bouche d'admission (4), et sa vitesse se voit accélérée grâce à la conicité de la corolle (1). Il actionne alors l'hélice (2) selon la loi du carré des vitesses. Par la cause que l'hélice (2) se trouve entièrement carénée dans la corolle(1), le système s'avère être une éolienne à réaction. 10- Il n'est pas indispensable que l'hélice soit surdimensionnée alors qu'une hélice de refroidissement de camion peut suffire, tandis que pour des questions énergétiques doublées d'esthétique, on peut toujours jumeler deux éoliennes, ou les monter en V dans le cas de l'installation de trois éoliennes à réaction. Enfin, pour que la corolle (1) se trouve toujours dans le sens du vent, tournant sur son axe (5), est guidée par la gouverne (6) selon le principe des girouettes. DESCRIPTION 1- Currently, wind turbines are naked in the face of the wind without any device comes to improve their performance. The invention is in the form of a corolla (1) in which the propeller (2) is housed at the bottom, in the exhaust neck (3). 5- The wind rushes into the intake mouth (4), and its speed is accelerated thanks to the conicity of the corolla (1). It then actuates the propeller (2) according to the law of the square of velocities. Because the propeller (2) is fully streamlined in the corolla (1), the system turns out to be a jet wind turbine. 10- It is not essential that the propeller is oversized while a truck cooling propeller can suffice, while for energetic questions coupled with aesthetics, we can always twin two wind turbines, or mount them in V in the case of the installation of three jet wind turbines. Finally, so that the corolla (1) is always in the direction of the wind, turning on its axis (5), is guided by the rudder (6) according to the principle of wind vanes.
