The cartridge of a fan outlet for a multiple flow turbojet engine is made of composite material and includes two thick lateral strips (8a, 8b) positioned in the interior of the outer case and a narrow central band pierced with slots (10) in which guide vanes (5), provided with an in-molded cover, come to be fixed. The outer cartridge can be integral with the support of soundproofing panels (7 and 9) and support the abradable part (6) facing fan (3).

Multiple flow turbojet engine with an outer ring of the fan outlet

The radially outer end of the aerofoil portion of each vane of a stator assembly for the fan of a turbo-jet engine is bent at right angles and is inserted in a slot-like opening provided in an outer ring which is fixed to the casing via screws in conjunction with spacers each of which has a foot which partly overlaps the adjacent opening.
