Abstract

L'invention concerne les rotors de compresseurs centrifuges. Les ailettes principales 44 d'un rotor de compresseur 30 comprennent une partie propulsive 50 et une partie directrice 52. La partie propulsive est inclinée vers l'avant par rapport au disque du rotor, lorsqu'on considère le sens de rotation, et la partie directrice est encore inclinée davantage vers l'avant. Application aux compresseurs de turbines à gaz.
