Abstract

L'invention concerne un turbopropulseur (19) comprenant un arbre d'hélice (21) et un générateur de gaz (22) qui longe cet arbre d'hélice (21) et qui comporte un arbre haute pression (24), ce turbopropulseur comportant une conduite d'entrée d'air (31) du générateur de gaz terminée par une bouche d'admission (33). La bouche d'admission (33) est déportée radialement par rapport à l'arbre haute pression (24), la conduite d'entrée d'air (31) comporte une portion frontale (38) comprenant une ouverture s'étendant autour de l'axe de l'arbre haute pression (24), et il comporte une boîte d'accessoires (41) située en amont d'une extrémité avant de l'arbre haute pression selon l'axe de cet arbre haute pression (24). La boîte d'accessoires (41) est accouplée à l'extrémité avant de l'arbre haute pression (24) à travers l'ouverture de la portion frontale (38).The invention relates to a turboprop engine (19) comprising a propeller shaft (21) and a gas generator (22) which runs alongside this propeller shaft (21) and which comprises a high pressure shaft (24), this turboprop engine comprising an air inlet pipe (31) of the gas generator terminated by an inlet mouth (33). The intake port (33) is radially offset relative to the high pressure shaft (24), the air inlet pipe (31) has a front portion (38) comprising an opening extending around the 'axis of the high pressure shaft (24), and it comprises an accessory box (41) located upstream of a front end of the high pressure shaft along the axis of this high pressure shaft (24). The accessory box (41) is coupled to the front end of the high pressure shaft (24) through the opening in the front portion (38).
