Abstract

L'INVENTION CONCERNE UNE AUBE CREUSE POUR MOTEUR A TURBINE A GAZ, REFROIDIE PAR CIRCULATION INTERNE D'AIR. LA PARTIE AERODYNAMIQUE, CREUSE, DE L'AUBE EST DIVISEE PAR UNE MEMBRANE PERFOREE 23 EN UNE CHAMBRE AVANT ABRITANT UN TUBE D'ENTREE D'AIR 21 PAR LES PERFORATIONS DUQUEL L'AIR S'ECHAPPE SOUS FORME DE JETS VENANT FRAPPER ET REFROIDIR LA FACE INTERNE DE L'AUBE, PUIS GAGNE UNE PREMIERE PARTIE D'UN SECOND TUBE ABRITE DANS UNE CHAMBRE ARRIERE OU IL REFROIDIT DE MEME UNE PARTIE DE LA FACE INTERNE DE L'AUBE AVANT DE S'ECHAPPER PAR LE BORDDE FUITE 32. LA SECONDE PARTIE DU SECOND TUBE, SEPAREE DE LA PREMIERE PAR UNE CLOISON 31, EST ALIMENTEE SEPAREMENT EN AIR ET ASSURE LE REFROIDISSEMENT PAR IMPACT DE L'AUTRE PARTIE DE LA FACE INTERNE DE LA PARTIE ARRIERE DE L'AUBE. DES OUVERTURES DANS LA PAROI DE L'AUBE PERMETTENT A UNE PARTIE DE L'AIR AYANT REFRIGERE PAR IMPACT LA FACE INTERNE DE L'AUBE DE S'ECHAPPER POUR REALISER UN REFROIDISSEMENT LAMINAIRE DE LA SURFACE EXTERNE. LE DISPOSITIF PERMET LA REFRIGERATION DES DIVERSES PARTIES DE L'AUBE AU MOYEN D'UN COURANT D'AIR UNIQUE.
