Abstract
MOTEUR PRESENTANT UNE REPARTITION PERIPHERIQUE PRESELECTIONNEE DE LA TEMPERATURE DES GAZ CHAUDS DANS LE PLAN DE SORTIE DE LA CHAMBRE DE COMBUSTION. IL COMPREND UNE CHEMISE INTERIEURE 48 ET UNE CHEMISE EXTERIEURE 50, DE CHAMBRE DE COMBUSTION, ET UN MOYEN DISPOSE EN AMONT DES AUBES FIXES 46, SOUS LA FORME D'OUVERTURES 78 ET 80 POUR L'ADMISSION D'AIR DANS LA CHAMBRE DE COMBUSTION DE FACON A CREER UNE REPARTITION DE LA TEMPERATURE AU NIVEAU DES AUBES FIXES TELLE QUE LES GAZ CHAUDS S'ECOULANT DANS LES ESPACES 84 LIMITES PAR LES AUBES FIXES 46 ONT UNE TEMPERATURE SUPERIEURE A LA TEMPERATURE MOYENNE D'ENTREE DANS LA TURBINE ET LES GAZ CHAUDS HEURTANT LE BORD D'ATTAQUE 82 DES AUBES FIXES 46 ETANT A UNE TEMPERATURE INFERIEURE A CETTE TEMPERATURE MOYENNE D'ENTREE. APPLICATION AUX MOTEURS D'AVION.ENGINE WITH A PRESELECTED PERIPHERAL DISTRIBUTION OF HOT GAS TEMPERATURE IN THE COMBUSTION CHAMBER EXIT PLANE. IT INCLUDES AN INTERNAL SHIRT 48 AND AN EXTERNAL SHIRT 50, OF COMBUSTION CHAMBER, AND A MEDIUM HAS FIXED BLADES 46, IN THE FORM OF OPENINGS 78 AND 80 FOR THE ADMISSION OF AIR INTO THE COMBUSTION CHAMBER OF WAY TO CREATE A TEMPERATURE DISTRIBUTION AT THE LEVEL OF THE FIXED BLADES SUCH AS THE HOT GAS FLOWING INTO THE SPACES 84 BOUNDARED BY THE FIXED BLADES 46 HAVE A TEMPERATURE GREATER THAN THE AVERAGE ENTRY TEMPERATURE INTO THE HOT GAS AND TURBINE HOT THE LEADING EDGE 82 OF THE FIXED BLADES 46 BEING A TEMPERATURE LOWER THAN THIS AVERAGE ENTRY TEMPERATURE. APPLICATION TO AIRCRAFT ENGINES.
