Abstract

L'invention se rapporte à une nacelle (3) de turboréacteur à double flux à soufflante à calage variable, la nacelle comportant une section avant (300) destinée à entourer la soufflante du turboréacteur, et une section arrière (310), la section arrière (310) comportant une structure interne (314) destinée à entourer le corps primaire du turboréacteur, la structure interne (314) définissant avec une structure externe (312) de la section arrière (310) une veine secondaire pour l'écoulement d'un flux d'air, la structure externe (312) de la section arrière (310) étant mobile en translation par rapport à la section avant (300), entre une position avancée, dans laquelle la structure externe (312) assure la continuité aérodynamique avec la section avant (300), et une position reculée, dans laquelle la structure externe (312) ouvre un passage vers la veine secondaire, la structure externe (312) comportant un élément tubulaire (318) apte à prendre une position de maintenance par rotation autour d'un axe (316) perpendiculaire à un axe longitudinal de la nacelle, l'élément tubulaire (318) libérant en position de maintenance un accès à la structure interne (314).
