Abstract

Un procédé de fabrication dun revêtement en composite pour un aéronef à rotors basculants consiste à fournir un premier revêtement dans un moule et des panneaux en nid dabeilles ayant un réseau de grandes cellules sur le premier revêtement. Le procédé consiste à assembler les panneaux en nid dabeilles le long dun axe longitudinal du premier revêtement pour former une âme en nid dabeilles et à positionner des éléments de remplissage entre les panneaux en nid dabeilles et à positionner des éléments de remplissage sur les extrémités extérieures de lâme en nid dabeilles. Le procédé consiste à positionner un second revêtement sur lâme en nid dabeilles et à durcir ladhésif pour créer un lien entre le premier revêtement, lâme en nid dabeilles et le second revêtement pour former le revêtement en composite. Le procédé consiste à fournir un soutien et une résistance suffisante à la compression pour une aile de laéronef à rotors basculants, tout en réduisant le temps de fabrication et la main-duvre associés aux méthodes conventionnelles qui consistent à poser des plis de centaines de bandes de renforcement constituées de divers types et de diverses tailles et orientations.
