Embodiment Construction

[0035] Figure 4 to Figure 6 An engine aft mounting section 52 configured for connecting the engine to the primary structure of the aircraft pylon is depicted.

[0036] The rear mounting section 52 of the engine includes a first portion 54, a second portion 56 ( Figure 5 with Image 6 can be seen in ) and connecting elements 58, the first part corresponding to a part of the engine or fixed to the engine, the second part corresponding to a part of the main structure or fixed to the main structure, these connecting elements connect the first and The second parts 54 and 56 are connected.

[0037] Alternatively, the first part 54 corresponds to or is fixed to a part of the main structure and the second part 56 corresponds to a part of the engine or is fixed to the engine.

[0038] The first and second portions 54 , 56 respectively include first and second contact surfaces 54S and 56S that are oriented toward each other, contact each other, or alternatively are separated from e...

Abstract

The invention relates to an aircraft engine assembly comprising first and second parts (54, 56) connected by a connecting element (58) and characterized in that one of the two connected parts comprises a At least one transverse hole (76) on the contact surface (74) of the part (56) and at least two through-holes (72) leading into the at least one transverse hole, each intended to receive one of these connecting elements (58) A threaded shank (66) and characterized in that the engine mounting section includes a transverse nut comprising at least two bodies (80.1, 80.2) joined together, each body having a A tapped hole into which one of the shanks (66) engages.

Description

technical field [0001] The invention relates to an aircraft engine mounting section comprising at least one transverse nut and an aircraft comprising said engine mounting section. Background technique [0002] according to figure 1 with figure 2 In the configuration seen in FIG. 1 , aircraft 10 includes several engine assemblies 12 positioned below wing structure 14 of aircraft 10 and each including an engine 16 connected to wing structure 14 by pylons 18 . [0003] The pylon 18 includes a rigid primary structure 20 which, among other things, transfers loads between the engine 16 and the rest of the aircraft 10, and a secondary structure which wraps the primary structure 20 and limits the drag of the pylon. [0004] Throughout the description, the longitudinal direction DL is a direction substantially parallel to the engine axis A18. A transverse direction is a direction substantially parallel to the axis of the wing structure 14 . The concepts of top and bottom refer t...
