Title (EN) THRUST REVERSER CASCADE FOR AN AIRCRAFT NACELLE
(FR) GRILLE D'INVERSEUR DE POUSSÉE POUR NACELLE D'AÉRONEF
Abstract:
(EN) The invention relates to a thrust reverser cascade (1) for an aircraft nacelle, comprising a plurality of blades (2) having a first (6a) and a second surface (6b), the blades (2) being connected to members (3, 4) connected to attachment flanges (5) for attaching the thrust reverser cascade (1) to the nacelle. According to the invention, at least one of the surfaces (6a, 6b) of the blades (2) is covered with at least one layer of fibres (7) each comprising a plurality of fibre pieces which are pre-impregnated with resins, the fibre pieces being superimposed on one another, positioned parallel to the aerodynamic surface of the blade (2) and oriented in different directions.
(FR) L'invention concerne une grille d'inverseur de poussée (1) pour nacelle d'aéronef comprenant une pluralité d'aubes (2) présentant une première (6a) et une deuxième surface (6b), lesdites aubes (2) étant reliées à des longerons (3, 4) raccordés à des brides de fixation (5) destinées à la fixation de la grille d'inverseur de poussée (1) sur la nacelle. Selon l'invention, au moins l'une des surfaces (6a, 6b) des aubes (2) est tapissée d'au moine une nappe de fibres (7) comprenant chacune une pluralité de morceaux de fibres pré-imprégnées de résines, les morceaux de fibres étant superposés les uns sur les autres, positionnés parallèlement à la surface aérodynamique de l'aube (2) et orientés selon différentes directions.
