A discharge grille of an intermediate casing of a turbomachine includes a peripheral edge and a seal mounted on the peripheral edge via an attachment system, the seal ensuring the sealing between a first turbomachine member and a second member of the turbomachine, and surrounding the discharge grille of the intermediate casing, the seal having a U-shaped cross section and includes a base plate configured to bear against the first member, a sealing lip configured to bear against the second member through deformation of the sealing lip to ensure air tightness and fire proofing through contact.

Seal for an intermediate turbomachine casing

An air-fire seal designed to be attached to a first tubular member of a turbomachine, such as a bleed duct, and to rest against a second member of the turbomachine, such as an intermediate casing hub, includes an attachment base having an annular shape around a reference axis (Y); a first annular fire-stop lip extending from the attachment base over a first length (L); and a second annular air-sealing lip extending from the attachment base over a second length (L) lower than the first length and facing the first lip.

Air-fire seal and assembly comprising such a seal

A turbine engine for an aircraft which includes, in general, at least one assembly made up of a first part wherein a second part is attached with an attachment device including a milled head applied to the first part and a body engaging with the second part in order to clamp the parts. The recess of the head of such an attachment device requires a boss on the first part, which is complex and expensive to produce using conventional techniques. Such a boss can be replaced with a removable seat having an opening through which the body passes and forming a recess for the head, a bearing surface for the head, and abutment device applied to the first part in order to prevent a movement of the seat towards the second part.

A discharge conduit suitable for use with a turbine engine. The discharge conduit includes an air intake end, an air outlet end and a tubular duct for guiding air between the air intake and air outlet ends. The air intake end is equipped with attachment elements for attachment to an intermediate casing of the turbine engine. The attachment element can be of the resilient snap-in type.
