Abstract

L'invention concerne un ensemble propulsif pour aéronef comprenant un mat et une turbomachine à double flux ayant un conduit de soufflante (10) dans lequel s'écoule un flux d'air (F), la turbomachine comprenant en outre un système d'admission d'air avec un dispositif de prise d'air froid (27) pour prélever une partie du flux d'air (F) dans le conduit de soufflante, ledit dispositif comprenant une écope (31) coulissante comprenant une face amont ouverte pour laisser passer l'air et une cloison inférieure ayant une ouverture de sortie d'air connecté à un échangeur (22), l'écope (31) pouvant coulisser entre une position d'ouverture, dans laquelle l'écope (31) s'étend au moins en partie dans le conduit de soufflante (10) et dans laquelle une partie de l'écoulement de l'air dans le conduit de soufflante (10) s'engouffre dans l'écope par sa face amont et une position de fermeture, dans laquelle l'écope (31) ne s'étend pas dans le conduit de soufflante (10) et a sa cloison supérieure (3 le) obturant la découpe.
