Abstract: The present invention relates to a nacelle (1) for a jet engine (4) comprising a forward air inlet section (5), a mid-section (6) intended to surround a jet engine fan, and an aft section (9), at least one portion forming the aft section being connected to the mid-section via an at least partially peripheral radial knife-edge (31) capable of engaging by complementarity of shape with a corresponding groove (32) belonging to a portion (6a) of the mid-section, characterized in that the knife-edge comprises at least one reinforcing segment (35, 36) situated in a region for accommodating high loads, said reinforcing segment being made from a material which is stronger than the remainder of the knife-edge and tailored to the loads which are to be borne by said segment in this region.

Abstract: The nacelle (1) comprises an air intake (5) upstream of the turbojet engine (2), a middle section (6) an internal casing (6a) of which is intended to surround a fan (3) of the turbojet engine (2), and a downstream section (7) comprising an external structure (7a)which is rigidly connected to a downstream part of the casing (6a) of the fan (3) so as to support the turbojet engine (2) and has means of attachment to a strut (12) intended to be connected to a fixed structure (13) of an aeroplane.

Abstract: A fail safe emergency lock for a thrust reverser is disclosed in which the thrust reverser is located on a jet engine having a cowling bounding a gas flow duct, the cowling having at least one reverse thrust opening in communication with the gas flow duct. The thrust reverser has a thrust reverser panel movably mounted on the cowling so as to be movable between a forward thrust position, in which the thrust reverser panel covers the reverse thrust opening, and a reverse thrust position in which the reverse thrust opening is uncovered.
