Abstract

TUYERE DE DISTRIBUTION D'UN GAZ CHAUD. UNE ENVELOPPE METALLIQUE INTERIEURE 34 EST RELIEE A UNE ENVELOPPE METALLIQUE EXTERIEURE 38 PAR UN NOMBRE LIMITE D'AILETTES METALLIQUES 32 QUI ASSURENT LA RIGIDITE DE LA STRUCTURE. UNE PLURALITE D'AILETTES DE GUIDAGE DE L'ECOULEMENT, REALISEES EN CERAMIQUE 30, SONT RELIEES AUX ENVELOPPES PAR DES ATTACHES ELASTIQUES 50. L'INVENTION S'APPLIQUE PARTICULIEREMENT A DES TUYERES D'ADMISSION DE TURBINE A GAZ ET PERMET DE FONCTIONNER A DES TEMPERATURES PLUS ELEVEES AVEC MOINS D'AIR DE REFROIDISSEMENT.
