Abstract

L'invention concerne un système de propulsion (150) comprenant un mât (152), une turbomachine (202) avec un noyau (204) et une nacelle (154). La nacelle (154) comporte deux capots intérieurs (256a-b) et deux capots extérieurs (258a-b) autour des capots intérieurs (256a-b), où chaque capot extérieur (258a-b) est monté articulé par l'intermédiaire de charnières et est mobile entre une position fermée dans laquelle le capot extérieur (258a-b) est resserré autour du noyau (204) et une position ouverte dans laquelle le capot extérieur (258a-b) est écarté du noyau (204). En outre, chaque capot intérieur (256a-b) est monté articulé sur le mât (152) par l'intermédiaire de charnières fixes (257a-b) et est mobile entre une position fermée dans laquelle le capot intérieur (256a-b) est resserré autour du noyau (204) et une position ouverte dans laquelle le capot intérieur (256a-b) est écarté du noyau (204). La mise en place de charnières entre le mât et chaque capot intérieur permet de dissocier la rotation du capot intérieur de la rotation du capot extérieur associé.
