Embodiment Construction

[0044] refer to figure 1 , shows an aircraft 200 comprising a fuselage 3, two wings 2 ( figure 1 Only one of them is visible) fixed to the fuselage, each wing carrying one or more engine assemblies 5 according to the invention. The engine assembly 5 , also called propulsion assembly, comprises a turbofan engine 10 , such as a turbojet engine, a device 4 for attaching the engine 10 , also called a mounting pylon, and a nacelle 11 surrounding the engine. Conventionally, the engine assembly 5 is suspended below its wing 2 .

[0045] Throughout the following description, by convention, the direction X corresponds to the longitudinal direction of the device 4, which is equivalently similar to the longitudinal direction of the turbojet engine 10 and the longitudinal direction of the engine assembly 5, this direction X being parallel to the longitudinal direction of this turbojet engine 10 Axis 9. On the other hand, the direction Y corresponds to the direction oriented transversel...

Abstract

An engine assembly for an aircraft, comprising an engine mounting pylon comprising a primary structure (8) forming a box closed by a front closing rib (42a), a front engine mount (7c) comprising at least two connecting link rods (56) that are disposed laterally on either side of the box and each comprise a first end mounted on a first fitting of the casing. The rib (42a) forms a part of the frontmount (7c), comprising at least one transverse fitting (50) made in one piece so as to close a front end of the box and to have lugs (52) protruding laterally on each side of the box, each lug (52) being provided with a first orifice (54) for mounting a second end of one of the link rods (56).

Description

technical field [0001] The invention relates to the field of engine assemblies for aircraft, said engine assembly comprising an engine, and a device for attaching the engine under a wing of the aircraft. Such an attachment device is known, for example, from document FR 3 014 840 . [0002] It is preferably applied to commercial aircraft. Background technique [0003] On existing aircraft, engines, such as turbofan engines, are usually attached to the underside of the wing by complex attachment devices called EMS (Engine Mounting Structures) or mounting pylons. Customary mounting hangers have a main structure, also called a rigid structure. This rigid structure usually forms a box, ie by assembling upper and lower stringers interconnected by a number of transverse stiffeners located inside the box. The stringers are arranged as upper and lower faces, while the side panels close the sides of the box. The angle brackets can provide a mechanical connection between these cons...
