Abstract

Turbomachine. La majorité des rotors d'un turbocompresseur à étages multiples sont des rotors du type à flux diagonal ou à << flux mixte >> dont les angles de flux de sortie augmentent des rotors de l'étage initial en direction des rotors de l'étage final, la vitesse spécifique de chaque rotor tombant de ce fait dans la gamme optimale dudit rotor. Turbocompresseur à étages multiples à arbre unique.
