Problems solved by technology

[0014] However, this main structure has a large overall volume, especially due to the presence of bows connecting the side beams
This bulk can make it more difficult to install surrounding elements such as the nacelle, engine auxiliary systems, thrust reversers, moving leading edge flaps, etc.

Embodiment Construction

[0048] refer to Figure 1 to Figure 4 , Figure 1 to Figure 4 An assembly 1 for an aircraft according to a first preferred embodiment of the invention is depicted.

[0049] Overall, such an assembly 1 comprises a wing element 2 corresponding to a wing of an aircraft, an inboard jet engine 10 , such as a turbojet engine, and an attachment pylon 4 for attaching the engine 10 . Furthermore, assembly 1 comprises attachment means 7 for attaching turbojet engine 10 to primary structure 6 of pylon 4 and attachment means 8 for attaching primary structure 6 to wing element 2 .

[0050] Throughout the following description and by convention, the direction X corresponds to the longitudinal direction of the pylon 4 , which can also be similar to the longitudinal direction of the turbojet 10 . This direction X is parallel to the longitudinal axis 5 of the turbojet 10 . On the other hand, the direction Y corresponds to the direction oriented transversely with respect to the pylon 4 and c...

Abstract

In order to optimize the bulkiness of a primary structure of an aircraft engine attachment pylon and thus make it easier to install under the wing and as close as possible to the pressure face thereof, the disclosure herein provides an assembly in which the engine comprises a rear part arranged under a wing element equipped with a wing box, the primary structure being made up of the following independent elements: a first and a second side beam arranged one on each side of a vertical mid-plane of the engine; and an intermediate structure through which the vertical mid-plane of the engine passes and which is situated some distance from each of the first and second side beams.

Description

technical field [0001] The invention relates to the field of aircraft assemblies comprising wing elements, bypass engines and pylons for attaching engines intended to be arranged partly under the wing elements, the present invention The invention relates in particular to an assembly for an aircraft comprising a main structure of an attachment pylon formed by three separate elements. [0002] The invention also relates to an aircraft equipped with such an assembly. The invention is preferably applicable to commercial aircraft. Background technique [0003] In existing aircraft, exojet engines, such as turbojets, are suspended under the wings by complex attachment means also known as EMS (Engine Mounting Structure) or attachment pylons. Usually employed attachment means have a main structure, also called a rigid structure, usually made in the form of a single box, i.e. the main structure is joined by a plurality of transverse ribs located on the inside of the box. Composed ...
