Problems solved by technology

As a result, it becomes difficult to insert the pylon as well as the various wing attachments into this remaining vertical space normally used for such insertion
This difficulty is exacerbated with the high intensity of the forces transmitted and requires proper dimensioning for the wing box and main structure

Embodiment Construction

[0023] figure 1 Shown is an aircraft 10 comprising a fuselage 12 to which are secured two wings 102 (at figure 1 only one wing is visible in ).

[0024] Below each wing 102 is fixed at least one engine 150 , in particular a bypass and twin-body engine, such as a turbojet engine. The fixing of each engine 150 to the wing 102 is achieved by a pylon 110 arranged below the wing 102 .

[0025] Throughout the following description, by convention, direction X corresponds to the longitudinal direction of the engine 150, direction Y corresponds to the transverse direction of the engine 150, and direction Z corresponds to the vertical direction, these three directions X, Y and Z are orthogonal to each other .

[0026] The terms “forward”, “aft”, “port” and “starboard” should be considered relative to the forward direction of aircraft 10 , oriented according to longitudinal direction X, as encountered with thrust applied by engines 150 .

Abstract

A rear attachment between a hanger and an aircraft wing. The rear attachment (100) between a main structure (206) having a tail wall (208) and a wing box (202) having a lower wall (204), comprises: a wing attachment (302) comprising a plate (304) and a main wall (306), where the plate (304) is fixed to the lower wall (204); a front right angle plate and a rear right angle plate, where each right angle plate comprises vertical walls (312a-b) and horizontal walls (314a-b), and the main wall (306) is between the vertical walls (312a-b); and an assembly (320) comprising a base (322), a port column (324a) and a starboard column (324b) secured to the base (322), the base (322) being secured to the tail wall (208), where each vertical wall (312a-b) and the main wall (306) have, for each column (324a-b), a hole (326) in which the column (324a-b) fits. Such a rear attachment allows space savings in the vertical direction and thereby allows the hanger to be closer to the wing.

Description

technical field [0001] The invention relates to a rear attachment between a pylon and a wing of an aircraft, and to an aircraft comprising at least one such rear attachment. Background technique [0002] In existing aircraft, engines such as turbojet engines are mounted via a complex mounting arrangement (dispositif d'accrochage) (also known as "EMS" ("Engine Mounting Structure" in English) or mounts (mât d'accrochage). ) while hanging under the wing. Usually used pylons have a main structure (also called a rigid structure), usually produced in the form of a box (caisson), that is, by the assembly of a lower beam and an upper beam, where The lower and upper beams are connected to each other by a number of transverse stiffeners located inside the box and at its ends. These beams are arranged on the lower and upper surfaces, while the side panels close the box on the sides. In addition, the hanger is arranged on the engine In the upper part of the engine, between the upper pa...
