A seal interposed between a turbojet engine and a movable part of a nacelle includes a tubular body delimiting an inner cavity interposed between at least one fixing part and a platform. The platform includes a first lateral edge, a second lateral edge and a planar surface extending from the first lateral edge to the second lateral edge. The seal includes a protuberance arranged on the platform. The protuberance is centered on the platform or extends from the first lateral edge to the second lateral edge.

Aircraft seal

A sealing joint for an aircraft turbojet engine nacelle includes a bead designed to be mounted in a joint support. The sealing joint is characterized in that the bead includes a retaining projection which extends in a direction substantially transverse to a longitudinal axis of the sealing joint, the retaining projection being designed to extend through the joint support when the sealing joint is mounted in the support thereof and/or a sealing lip which extends under the bead in a direction substantially parallel to the longitudinal axis of the sealing joint and which is designed to be compressed on the joint support when the sealing joint is mounted in the support thereof.

A device for securing at least one thermal protection mat to an internal fixed structure of a nacelle includes at least one removable fastening element for securing the at least one thermal protection mat to the internal fixed structure designed to be arranged between the mat and the internal fixed structure. The device includes at least one gripping element connected to the removable fastening element to project relative to the mat on the opposite side to the internal fixed structure, the removable fastening element being intended to be detached from the internal fixed structure by a pulling force exerted on the gripping element.

The present disclosure relates to an assembly of an inner fixed structure of a turbojet engine nacelle and of a thermal protection, said structure including an inner face, on which the thermal protection is added, and an outer face constituting a portion of the inner surface of a cold flow path, the assembly including at least one channel put in fluid communication the inner face and the outer face of the structure.

Assembly of an inner fixed structure of a turbojet engine nacelle and of a thermal protection

The disclosure relates to an aircraft propulsion assembly comprising a bypass turbojet engine equipped with a nacelle, the bypass turbojet engine including a structure defining a first part of a secondary flow path for channeling secondary flow, and the nacelle having a structure defining a second part of the secondary flow path. The structure of the nacelle defining the second part of the secondary flow path is arranged such that the first part and the second part of the secondary flow path are angularly offset around a longitudinal axis of the engine when the engine is shut down/stopped.

Aircraft propulsion assembly

A turbofan nacelle includes a cowl and a service structure, both being annular shapes in two halves. The cowl and the service structure are hinged on axes in respective halves to be opened during maintenance and closed during operation. In particular, a first annular half of the service structure supports a strike and a second annular half of the service structure supports a mobile bolt on a lever, such that the assembly constitutes a lock for closing the service structure. The lever engages with a locking member of a free edge of one half of the cowl, which is retracted when the lever is in the normal closed position thereof and active otherwise.
