Abstract

Dans la zone de la couche limite d'un disque circulaire 1 entraîné en rotation par une force motrice extérieure et agissant de préférence par une de ses faces, le fluide propulseur est accéléré radialement et tangentiellement. Une fois la vitesse maximale atteinte à la périphérie du disque, le fluide qui doit être aspiré est entraîné par le fluide propulseur. Il s'écoule alors depuis un carter muni d'une tubulure d'aspiration 5, entre le disque rotatif 1 et une bride annulaire 3 du carter, vers une chambre de mélange et de diffusion. Cette chambre est définie entre ladite bride et une rondelle annulaire de protection 4. Des rainures radiales 8 sur la face du disque exposée au fluide propulseur augmentent l'effet d'aspiration et la hauteur d'élévation. L'avantage de l'invention consiste en ce que la masse de fluide propulseur accéléré est faible par rapport à la surface d'injection, de sorte qu'avec une puissance absorbée relativement faible on obtient un effet de mélange et un débit plus puissants.
