Embodiment Construction

[0027] figure 1 Aircraft 10 is shown with propulsion system 100 having jet engines 102 secured to wings 104 of aircraft 10 by engine pylons 106 . The wing 104 and the engine pylon 106 form an assembly according to the invention, and the jet engine 102 is fastened below the engine pylon 106 .

[0028] In the following description, terms of position are considered relative to the aircraft in its normal flight position, i.e. as figure 1 shown, and the "front" and "rear" positions are considered relative to the front and rear of the jet engine, and relative to the direction of forward movement F of the aircraft 10 when the jet engine 102 is in operation. considerate.

[0029] In the following description, and by convention, the X-direction is the longitudinal direction of the jet engine, which is parallel to the longitudinal axis of said jet engine, the Y-direction is the transverse direction, which is horizontal when the aircraft is on the ground, and The Z direction is a vert...

Abstract

An assembly for an aircraft that has a wing and an engine pylon having a primary structure with right-side and left-side panels, an upper and a lower spar and a rear rib, two sets of upper or lower shackles, one set fastening the right-side panel to the wing, and a second set fastening the left-side panel to the wing, a fastening element secured to the rear rib or to the lower spar, a rear rod connecting the fastening element to the wing, a transverse shackle connecting the upper spar to the wing, a line connecting two centers of the transverse shackle being oriented transversely relative to a longitudinal axis of the engine pylon, and a reinforcing panel, at each joint between a right-side or left-side panel and an upper or lower shackle, which is fastened along a height against the panel and to which the shackle is also fastened.

Description

technical field [0001] The present invention relates to an assembly for an aircraft having a wing and an engine pylon for mounting a jet engine under the wing, and to an assembly having a jet engine and such a pylon for mounting a jet engine Components under the wings of the aircraft. Background technique [0002] Typically, for aircraft, the propulsion assembly has jet engines fastened under the wings of the aircraft by means of engine pylons. An engine pylon generally consists of a main structure formed by a box formed by an upper spar, a lower spar and two lateral panels connecting the two spars, with internal ribs distributed along the box. [0003] The jet engine is secured under the engine pylon by means of engine attachments which conventionally include: a front engine attachment at the front, an aft engine attachment at the rear, and An assembly for reacting thrust between the front engine attachment and the aft engine attachment, which assembly includes reaction r...
