Title
(EN) TURBO WIND POWER ENGINE
(FR) TURBO-EOLIENNE
Abstract
(EN)
A wind power engine comprises a conical multiple-blade turbine obligatorily surrounded by a circular deflector which creates a clear space for the evacuation of the air that has worked without being deflected by the peripheral wind (Fig. 4). The deflector also produces an acceleration of the peripheral air, thereby increasing the pressure drop and hence the useful power behind the turbine. The conical turbine may be replaced by a multiple-blade wheel if the wind is first deviated by a deflector grille so as to attack the blades obliquely, which is the principle underlying the invention, the peripheral deflector remaining obligatorily around the wheel (Fig. 2). The essential advantage of this lies in the reduction by 3/4 of the diameter of the rotating part with respect to conventional propellers. This confers a high degree of solidity on the machine, substantially reduces its manufacturing costs, and prolongs its service life.

Eolienne constituée par une turbine multipale en forme de cône, entourée obligatoirement par un déflecteur circulaire créant un espace de dégagement pour permettre l'évacuation de l'air ayant travaillé sans qu'il soit rabattu par le vent périphérique (Fig. 4). Ce déflecteur, en plus, provoque une accélération de l'air périphérique, ce qui augmente encore la dépression derrière la turbine, donc la puissance utile. La turbine cônique peut être remplacée par une roue multipale plate si le vent est d'abord dévié par une grille de déflecteurs de manière à attaquer obliquement les pales, principe de base de cette invention, le déflecteur périphérique restant obligatoirement autour de la roue (Fig. 11). L'avantage essentiel de ce dispositif réside dans la diminution des 3/4 du diamètre de la partie tournante par rapport aux hélices habituelles, ce qui donne une très grande solidité et réduit fortement le prix de l'appareil et augmente sa durée de vie.
