Abstract

L'INVENTION CONCERNE UN CONVERTISSEUR D'ENERGIE TOURNANT EMPLOYANT UN FLUIDE. LE CONVERTISSEUR COMPORTE UNE STRUCTURE 2 ENVELOPPANTE DANS LAQUELLE EST MONTE DE FACON TOURNANTE AU MOINS UN ROTOR MUNI D'AUBES 4, LA STRUCTURE 2 S'ETENDANT EN AVAL DES AUBES DANS LA DIRECTION AXIALE ET AYANT AU MOINS UNE DISCONTINUITE 1 PERIPHERIQUE VOISINE DES AUBES, CETTE DISCONTINUITE ETANT DE FORME AU MOINS PARTIELLEMENT INCURVEE EN SECTION TRANSVERSALE. LA DISCONTINUITE RECOIT LE TOURBILLONNEMENT DU FLUIDE CREE PAR LA ROTATION DES AUBES 4 DE SORTE QU'UN TOURBILLON OU VORTEX 3 ANNULAIRE STATIONNAIRE S'Y MAINTIENNE. L'INVENTION S'APPLIQUE PARTICULIEREMENT AUX COMPRESSEURS A FLUX AXIAL POUR TURBINE A GAZ, AUX DISPOSITIFS DE PROPULSION MARINS ET AUX COMPRESSEURS OU VENTILATEURS CENTRIFUGE OU A FLUX MIXTE.
