Abstract

L'invention concerne une structure de fixation d'élément transparent de corps de fenêtre d'aéronef civil comprenant un fuselage d'aéronef (1) et un élément transparent (2) monté sur le fuselage d'aéronef (1). Un cadre de bord (3) est assemblé autour de l'élément transparent (2). Une structure de fixation correspondant au fuselage d'aéronef (1) est formée sur le cadre de bord (3). Le cadre de bord (3) comprend un élément de pression (31) et un élément de fixation (32). L'élément de pression (31) travaille conjointement avec l'élément transparent (2) et appuie sur l'élément de fixation (32) pour générer une précontrainte, fixant ainsi l'élément transparent (2). La structure de fixation ne perturbe pas un équilibre de contrainte interne de l'élément transparent lui-même, assurant ainsi une stabilité structurale.
