An exterior ferrule of an intermediate housing for an aircraft turbine engine, the ferrule made of composite material comprising a downstream annular linking end forming a peripheral groove and intended to receive a complementary linking member provided on one or more nacelle cowls, the ferrule being made from: a first fibrous preform obtained by three-dimensional weaving of yarns and densified by a matrix, the preform defining a drum of the ferrule as well as a structural part of the downstream groove wall; and a second fibrous preform obtained by three-dimensional weaving of yarns and densified by a matrix, the preform defining a base abutting the exterior of the drum defined by the first preform, as well as a structural part of the upstream groove wall.

Discharge valve of an aircraft turbomachine, including a discharge gate intended to be mounted pivotably about an axis between a position for closing an air passage orifice and an open position of said orifice, the orifice being formed in an intermediate casing of the turbomachine, the discharge valve including a sealing device having a seal configured to be movably mounted on the intermediate casing and a movement system configured to move the seal between a first position in which the seal is intended to bear against the discharge gate when the gate is in a closure position, and a second position in which the seal is retracted with respect to the air passage orifice when the discharge gate is in an open position.

An intermediate turbojet case comprises a hub that supports removable panels and bleed lines, the hub comprising a flank provided with openings, each bleed line having an upstream end engaged in an opening in the flank and a downstream end terminated by a base plate through which it is fixed to an internal face of a removable panel by way of screws, each removable panel having a front edge at which it is fixed to an external lip of the hub by screws. At least one removable panel comprises a downstream edge supporting a retaining element close to the internal face to hold the base plate in contact with the internal face during a phase in which the removable panel is fixed to the hub by screwing, this phase preceding attachment of the base plate to the removable panel by screwing.
