Abstract
LE MOTEUR A TURBINE A GAZ COMPORTE UNE STRUCTURE TOURNANTE, UN TRAJET ANNULAIRE DE CIRCULAIRE DES GAZ AYANT LE MEME AXE QUE LA STRUCTURE TOURNANTE, UNE MULTITUDE D'AUBES DE ROTOR ACCOUPLEES A LA STRUCTURE TOURNANTE ET S'ETENDANT JUSQUE DANS LE TRAJET DE CIRCULATION DES GAZ DE SORTE QUE LE COURANT GAZEUX SUIVANT CE TRAJET PROVOQUE LA ROTATION DE LA STRUCTURE TOURNANTE PAR RAPPORT A L'ELEMENT FIXE, ET UNE MULTITUDE DE PALES D'HELICE A PAS VARIABLE QUI SONT ACCOUPLEES A LA STRUCTURE TOURNANTE EN ETANT DISPOSEES RADIALEMENT A L'EXTERIEUR DE CELLE-CI. LE PAS DES PALES EST MODIFIE PAR UN PIGNON 60 ACCOUPLE COAXIALEMENT A L'UNE DES PALES ET UN ENGRENAGE INTERNE DISPOSE RADIALEMENT AUTOUR DU PIGNON POUR ENTRAINER CE DERNIER. LE DEPLACEMENT ANNULAIRE DU PIGNON PROVOQUE UN DEPLACEMENT ANGULAIRE DE LA PALE PAR RAPPORT A LA STRUCTURE TOURNANTE. L'ENGRENAGE INTERNE 64 EST ANIME D'UN MOUVEMENT DE ROTATION AUTOUR DU PIGNON, D'OU IL RESULTE QUE LE PIGNON EST DEPLACE ANGULAIREMENT PAR RAPPORT A LA STRUCTURE TOURNANTE. APPLICATION AUX HELICES DES MOTEURS A TURBINE A GAZ.
