Abstract

L’invention a pour objet une chemise (23) de distribution d’air dans une pale, comprenant une paroi tubulaire (24) ayant une extrémité d’admission d’air (26), cette paroi tubulaire (24) comportant des trous pour distribuer l’air reçu par son extrémité d’admission (26). Cette chemise (23) comporte au moins une paroi de séparation (32, 33) s’étendant dans la paroi tubulaire (24), cette paroi de séparation (32, 33) ayant une ouverture (34, 37), pour partitionner l’espace interne de la paroi tubulaire (24) en plusieurs portions (E1, E2, E3).
