Abstract

L'invention vise à maintenir le rendement et le taux d'un compresseur de turbomachine pour diminuer sensiblement la consommation spécifique Cs, tout en garantissant une marge au pompage suffisante à charge partielle. Pour ce faire, il est proposé un procédé optimisé d'adaptation du flux d'air à une demande variable de débit ou de puissance mécanique ou électrique dans un compresseur centrifuge de turbomachines. Le procédé prévoit une diffusion du flux d'air (F) à travers un premier aubage annulaire (G1) de pales à calage variable (24) bordé radialement d'un deuxième aubage annulaire (G2) de même nombre de pales à calage fixe (28) d'extension équivalente, orientant la diffusion en extension radiale par couplage des pales (24, 28) des deux aubages. Selon ce procédé, chaque pale (24) du premier aubage (G1) est entraînée en rotation propre hors d'axe (X'X).
