Abstract

L’invention se rapporte à une grille (14) pour inverseur de poussée d’ensemble propulsif d’aéronef. La grille (14) comprend des longerons (24) et des aubes (22) formant des ouvertures permettant à un écoulement de fluide chaud de traverser transversalement la grille (14) par ces ouvertures. Selon l’invention, la grille (14) comprend des canaux de refroidissement (25) traversant les longerons (24) de manière à acheminer un écoulement de fluide froid longitudinalement à travers ce longeron (24) afin de refroidir la grille (14) réchauffée par l’écoulement de fluide chaud. Dans une application, la grille (14) est configurée dans un ensemble propulsif de sorte que ledit écoulement de fluide chaud comprenne une partie des gaz provenant de la veine primaire d’un turboréacteur à double flux de cet ensemble propulsif, et de sorte que ledit écoulement de fluide froid comprenne une partie du flux d’air provenant de la veine secondaire de cet ensemble propulsif.
