Abstract

L’invention concerne une aube (21a) d’entrée d’air pour une turbomachine d’aéronef, comprenant : un bras structural (22) s’étendant radialement par rapport à un axe, le bras (22) étant en outre tubulaire, comportant une cavité (34) interne configurée pour être alimentée par un flux (33) d’air de dégivrage, et un bord aval (31) comportant des ouvertures (39) d’évacuation de ce flux (33), etun volet mobile (24) monté pivotant en aval du bras (22), caractérisé en ce que le bras (22) est équipé d’un déflecteur (60) qui s’étend le long du bord aval (31) du bras (22) et qui comprend une paroi de guidage (61) configurée pour forcer ledit flux (33) d’air de dégivrage à s’écouler exclusivement sur une surface d’intrados (42) du volet (24).
