Embodiment Construction

[0054] refer to Figure 6 , it can be found that said 12 o'clock beam 1 b is bounded by a shell made of composite material 21 , which can be made, for example, of carbon fiber impregnated with polymerized hardened epoxy resin.

[0055] The shell is formed from one or more fabrics.

[0056] The shell surrounds the core material 23 such that the shell defines a cavity with a closed portion filled by the core material.

[0057] The core material is chosen to be rigid enough to be able to form the shaped core, and which is light enough not to cause an increase in the inherent weight of the composite material chosen (forming the shell of the 12 o'clock beam): as previously indicated, Rigid synthetic foams such as WF 100, or a honeycomb structure may be suitable examples.

[0058] Said rails 13, 15, which allow the sliding of the corresponding thrust reverser half-cowls, are made of the same composite material as said casing 21, either simultaneously with said casing, or by fasten...

Abstract

The invention relates to a beam (1b), in particular for a cascade thrust reverser, including a skin (21) made of a composite material and defining a closed section, wherein said beam is filled with a core material (23).

Description

technical field [0001] The invention relates to a beam, in particular for a cascade thrust reverser. Background technique [0002] As we all know, aircraft engines (usually turbine engine types) are housed inside the nacelle, and have other functions: [0003] - Provides aerodynamic rectification of the engine, [0004] - makes it possible to direct the outside air towards the engine, [0005] - Enables connecting the engine to the aircraft. [0006] Typically, the connection of the engine to the aircraft is achieved using a support structure consisting of two upper stringers (commonly called the 12 o'clock beams because they are located on top of the nacelle), two lower stringers (because they are located The lower part of the nacelle, commonly referred to as the 6 o'clock beam) and a substantially ring-shaped assembly called the front frame, which is, in fact, formed by two half-frames, each between the upper rail and the Extending between the side sills and is designe...
