  • Patent number: 10533455
    Abstract: 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.

  • Patent number: 10337456
    Abstract: The invention relates to an intermediate casing hub of an aircraft turbojet engine, which includes: an outer shroud (14) intended for defining a secondary flow space of a stream of secondary gas on the inside and an inter-flow area on the outside, the outer shroud (14) being provided with a secondary opening (29), and a bleed valve comprising an outlet pipe (30) made of composite material, located in the inter-flow area, wherein the outlet pipe (30) is attached to the outer shroud (14) at the secondary opening (29), at least one gasket (33) for sealing against air and fire being arranged between the outlet pipe (30) and the outer shroud (14), and the outlet pipe (30) made of composite material includes a draped composite wall (30a, 30b), made up of a plurality of folds impregnated with resin.
