Abstract

L'invention concerne un ensemble de rotor s'étendant suivant un axe longitudinal (X) et comprenant : - un organe de prélèvement d'air (1) centripète s'étendant suivant un axe radial (Y) sensiblement perpendiculaire à l'axe longitudinal (X) et comportant une embase (14), et, - un disque (42, 42a, 42b) de rotor d'axe longitudinal (X) comportant un élément (9) annulaire coaxial à l'axe longitudinal, l'élément (9) annulaire comportant un logement (10) d'axe radial (Y) recevant au moins une partie de l'organe de prélèvement d'air (1). Selon l'invention, un anneau de blocage (11) est agencé entre l'organe de prélèvement d'air (1) et l'élément (9) annulaire, et configuré de manière à immobiliser radialement l'embase (14) de l'organe de prélèvement d'air (1) contre l'élément (9) annulaire sous l'action d'une force centrifuge.
