Abstract

MOTEUR A TURBINE A GAZ COMPORTANT UN GENERATEUR DE GAZ 16 POUR PRODUIRE DES GAZ DE COMBUSTION, AVEC UNE TURBINE DE PUISSANCE SUPPLEMENTAIRE 34, UNE SECTION A SOUFFLANTE SUPPLEMENTAIRE 54, ET UN SURPRESSEUR 64. LA TURBINE DE PUISSANCE COMPORTE DEUX RANGEES D'AUBES CONTRAROTATIVES 38, 42 QUI SONT ENTREMELEES EN ALTERNANCE ET SERVENT A ANIMER D'UN MOUVEMENT DE ROTATION DES PREMIER 46 ET SECOND 48 ARBRES D'ENTRAINEMENT, CONTRAROTATIFS, RESPECTIVEMENT. LA SECTION A SOUFFLANTE COMPORTE EGALEMENT DES SECTIONS DE PALES ESPACEES, CONTRAROTATIVES 60, 62 QUI SONT RESPECTIVEMENT RELIEES AUX PREMIER ET SECOND ARBRES. LE SURPRESSEUR EST MONTE AXIALEMENT ENTRE LES SECTIONS DE LA SOUFFLANTE. LE SURPRESSEUR COMPREND DES PREMIERES 68 ET SECONDES 72 RANGEES DE PALES, CONTRAROTATIVES, ENTREMELEES EN ALTERNANCE ET ENTRAINEES PAR LES PREMIER ET SECOND ARBRES. LE MOTEUR EST SUPPORTE PAR DEUX CHASSIS DE MANIERE A PERMETTRE AU BERCEAU DE NE PAS CONSTITUER UNE STRUCTURE. LE GENERATEUR DE GAZ EST UN ENSEMBLE MODULAIRE DE SORTE QU'IL PEUT ETRE SEPARE DE LA TURBINE, DE LA SOUFFLANTE ET DU SURPRESSEUR. APPLICATION AUX MOTEURS A TURBINE A GAZ.GAS TURBINE ENGINE INCLUDING A GAS GENERATOR 16 FOR PRODUCING COMBUSTION GAS, WITH AN ADDITIONAL POWER TURBINE 34, AN ADDITIONAL BLOWER SECTION 54, AND A BOOSTER 64. THE POWER TURBINE INCLUDES TWO ROWS OF CONTRAROTATING BLADES 38 , 42 WHICH ARE BETWEEN ALTERNATIVELY AND ARE USED TO ANIMATE A ROTATION MOVEMENT OF THE FIRST 46 AND SECOND 48 DRIVE SHAFTS, CONTRAROTATING, RESPECTIVELY. SECTION A BLOWER ALSO CONSISTS OF SPACED, CONTRAROTATING BLADE SECTIONS 60, 62 WHICH ARE RESPECTIVELY RELATED TO THE FIRST AND SECOND TREES. THE BOOSTER IS MOUNTED AXIALLY BETWEEN THE BLOWER SECTIONS. THE BOOSTER CONSISTS OF THE FIRST 68 AND SECONDS 72 ROWS OF BLADES, CONTRAROTATING, INTERMEDIATED IN ACTION AND DRIVEN BY THE FIRST AND SECOND TREES. THE MOTOR IS SUPPORTED BY TWO CHASSIS SO AS TO ALLOW THE CRADLE NOT TO CONSTITUTE A STRUCTURE. THE GAS GENERATOR IS A MODULAR ASSEMBLY SO THAT IT CAN BE SEPARATED FROM THE TURBINE, BLOWER AND BOOSTER. APPLICATION TO GAS TURBINE ENGINES.
