The present disclosure relates to the field of aircraft nacelles and concerns thrust reverser devices. More particularly, the present disclosure concerns a rear frame for a thrust reverser structure with a cascade vane of an aircraft nacelle, the nacelle comprising at least two longitudinal beams. The rear frame is intended to be attached to the two beams and to hold in place one or more cascade vanes in cooperation with a front frame. The rear frame comprises a common section having a substantially headband-like shape.

Rear frame for a thrust reverser structure with diversion grids

An aircraft nacelle includes: a thrust reverse device having movable cowls, and a supporting structure to support the thrust reverser device. The supporting structure includes: a base body extending along a longitudinal direction of the nacelle and made from a composite material, and a wall of the base body forming an unclosed cross section having an open portion to provide access to an inner surface of the supporting structure from outside, and a plurality of reinforcements which is made from a composite material, and attached on the inner surface along the longitudinal direction. In particular, the reinforcements are integrated in the inner surface of the supporting structure.

Thrust reverser supporting structure including composite reinforcements and a base having an unclosed cross section

The present disclosure relates to a beam, in particular for a cascade thrust reverser, including a skin made of a composite material and defining a closed section, wherein said beam is filled with a core material.

Beam for a cascade thrust reverser

A supporting half-structure for an aircraft engine nacelle is provided that includes at least one longitudinal beam and a front half-frame, the beam and the half-frame being formed of composite materials. The half frame has an open section, and the half-structure defines a structure selected from the group consisting of: the beam and the front half-frame form a one-piece part; the beam has an extension with an open section, the shape of which matches that of the front half-frame, the extension being attached to the half frame; and the front half-frame has an extension with an open shape, the shape of which matches the beam, wherein the extension is attached to the beam.

Nacelle for an aircraft engine

A stub frame for a cascade vane thrust reverser structure of an aircraft nacelle is attached to one or more cascade vanes. The stub frame includes an integral primary structure with a C-shaped longitudinal section, a secondary structure acting as a cascade edge and attached to the primary structure at one end, and transverse stiffeners connecting the two ends of the primary structure.
