Abstract

L'INVENTION CONCERNE LA PORTION D'UN STATOR DE TURBINE A GAZ, APPELEE ANNEAU DE TURBINE 4, QUI EST SITUEE RADIALEMENT EN REGARD DES AUBES MOBILES D'UN ETAGE DE TURBINE 3. L'ANNEAU DE TURBINE COMPORTE UN "ABRADABLE" 5 SUPPORTE PAR UN PREMIER CAISSON 6 ENTRETOISE PAR UN SECOND CAISSON 15 ET RELIE AU CARTER DE TURBINE 2 PAR UNE PAROI ANNULAIRE MINCE 8A, 10, DONC FLEXIBLE, ENCASTREE DANS LE CARTER 10A. DE L'AIR DE REFROIDISSEMENT GONFLE LE CAISSON INTERIEUR 15 POUR EPAULER LE CAISSON EXTERIEUR 6, CIRCULE ENTRE LES DEUX CAISSONS POUR LES REFROIDIR, ET REFROIDIT L'"ABRADABLE" 5 PAR IMPACT. APPLICATION AUX TURBOREACTEURS D'AVIATION.
