Abstract

L'INVENTION CONCERNE LES TURBOREACTEURS A DOUBLE FLUX. UN TURBOREACTEUR CONFORME A L'INVENTION COMPREND UN GENERATEUR DE GAZ 16 DESTINE A PRODUIRE DES GAZ DE COMBUSTION, UNE TURBINE DE PUISSANCE 30, UNE SECTION DE SOUFFLANTE ET UN COMPRESSEUR AUXILIAIRE 66. LA TURBINE DE PUISSANCE COMPORTE DES PREMIERES ET SECONDES COURONNES D'AUBES CONTRAROTATIVES 38, 42 QUI ENTRAINENT RESPECTIVEMENT DES PREMIERE ET SECONDE COURONNES D'AUBES DE SOUFFLANTE CONTRAROTATIVES 58, 62. LE COMPRESSEUR AUXILIAIRE COMPORTE DEUX ENSEMBLES DE COURONNES D'AUBES CONTRAROTATIVES 70, 74 QUI SONT EGALEMENT ENTRAINEES PAR LA TURBINE DE PUISSANCE. APPLICATION A L'AMELIORATION DU RENDEMENT DES TURBOREACTEURS A DOUBLE FLUX.THE INVENTION CONCERNS DOUBLE-STREAM TURBOREACTORS. A TURBOREACTOR IN ACCORDANCE WITH THE INVENTION INCLUDES A GAS GENERATOR 16 INTENDED TO PRODUCE COMBUSTION GAS, A POWER TURBINE 30, A BLOWER SECTION AND AN AUXILIARY COMPRESSOR 66. THE POWER TURBINE CONTAINS FIRST AND SECOND OWN RINGS. CONTRAROTATIVES 38, 42 WHICH DRIVE FIRST AND SECOND CONTRAROTATING BLOWER VELES RESPECTIVELY 58, 62. THE AUXILIARY COMPRESSOR INCLUDES TWO SETS OF CONTRAROTATIVE VANE CROWNS 70, 74 WHICH ARE ALSO DRIVEN BY THE POWERS. APPLICATION TO THE IMPROVEMENT OF THE EFFICIENCY OF DOUBLE-FLOW TURBOREACTORS.
