Abstract

L'INVENTION CONCERNE LES TURBOMACHINES COMPRENANT UN COMPRESSEUR FOURNISSANT DE L'AIR A UNE CHAMBRE DE COMBUSTION OU UN MELANGE PAUVRE DE CARBURANT ET D'AIR EST AMENE A UN DEGRE ELEVE DE VAPORISATION DANS UNE ZONE DE PRE-MELANGE DE LA CHAMBRE AVANT D'ETRE ENVOYE A TRAVERS UNE GRILLE DANS UNE ZONE PRINCIPALE DE LA CHAMBRE. LA GRILLE COMPREND UNE SERIE ANNULAIRE DE DEFLECTEURS 42 DISPOSES PAR PAIRES ESPACEES CIRCONFERENTIELLEMENT, DEFINISSANT CHACUNE UN CANAL 40. LES DEUX DEFLECTEURS D'UN CANAL COMPRENNENT UNE PARTIE COMMUNE 41 A PARTIR DE LAQUELLE ILS DIVERGENT EN DIRECTION DE LA ZONE PRINCIPALE. DEUX CANAUX ADJACENTS FORMENT ENTRE EUX UN PASSAGE 43 PAR LEQUEL PASSE LE MELANGE PROVENANT DE LA ZONE DE PRE-MELANGE POUR PARVENIR A LA ZONE PRINCIPALE. LA PARTIE COMMUNE DIVISE L'ECOULEMENT DU MELANGE SANS QU'IL Y AIT DE STAGNATION, CE QUI EVITE DES DEGATS A LA GRILLE DUS A LA CHALEUR PROVENANT DE LA ZONE PRINCIPALE.
