Abstract
L'invention concerne le domaine des turbomachines, et plus précisément une aube de guidage (13) comprenant un circuit (19) d'injection de liquide de refroidissement dans une veine d'air (20) d'une turbomachine (4) afin de permettre cette injection sans encombrement supplémentaire de la veine d'air (20) et avec un risque réduit de givrage.The invention relates to the field of turbomachines, and more precisely to a guide vane (13) comprising a circuit (19) for injecting coolant into an air stream (20) of a turbomachine (4) in order to allow this injection without additional bulk of the air stream (20) and with a reduced risk of icing.
