Abstract

L'invention concerne un système d'alimentation (10) de turbomachine, comprenant un circuit amont (100) comprenant un bloc de pompage basse pression (101) et au moins une pompe volumétrique haute pression (102). Le système d'alimentation (10) comprend, en aval du circuit amont (100), un circuit d'alimentation (60) d'un système d'injection (62), et un circuit d'alimentation (50) de géométries variables. Le circuit d'alimentation (60) du système d'injection comprend une boucle de retour (610) de fluide. Le circuit d'alimentation (50) de géométries variables est configuré pour acheminer du fluide transitant par des géométries variables (54) vers un nœud de sortie (S) raccordant le circuit d'alimentation (50) de géométries variables au circuit amont (100). Selon l'invention, le bloc de pompage basse pression (101) comprend une pluralité de pompes centrifuges (101a, 111a, 111b), et le nœud de sortie (S) est situé entre deux pompes (101a, 111a) du bloc de pompage basse pression (101).
