Embodiment Construction

[0048] figure 1 An aircraft engine assembly 1 is shown to be fixed under the wing 2 of the aircraft, comprising a suspension system 4 according to a preferred embodiment of the invention, and a suspension system such as a turbojet engine, etc., suspended under the system 4 the engine 6.

[0049] Overall, the suspension system 4 comprises a rigid structure 8, also referred to as the main structure, which carries suspension means for the engine 6 provided with a plurality of engine suspensions 10, 12 and for A system 14 that resists the thrust generated by the engine 6 .

[0050] It is noted that the assembly 1 will be surrounded by an engine nacelle (not shown) and that the suspension system 4 includes another series of suspensions (not shown) added to the rigid structure 8 and hang the assembly 1 under the aircraft wing 2.

[0051] Throughout the following description, X is, by convention, the longitudinal direction of the system 4 and in fact also the longitudinal directio...

Abstract

This invention relates to an aft pylon fairing (30) for A suspension system of an aircraft engine, comprising a main structure (60) extending along a longitudinal direction (X) of said fairing and integrating two side panels (44) connected to each other, the fairing also comprising a heat protection deck (32) mounted on said main structure (60) through connection means comprising tabs (62) designed to deform to accompany displacement of the deck (32) relative to the main structure (60), if there is differential thermal expansion between these two entities.

Description

technical field [0001] The present invention relates to a rear pylon fairing for an engine suspension system, the rear pylon fairing being designed to be inserted between an aircraft wing and an associated engine, the fairing being referred to as "APF" or "Rear hanger fairing". [0002] The present invention may be used on any type of aircraft equipped with a turbojet or turboprop. [0003] Suspension systems of this type, also referred to as "EMS" (Engine Mounting Structures), can be used for suspending a turbine engine below a wing of an aircraft, or for mounting the turbojet above the wing. Background technique [0004] This suspension system is designed to form a connection interface between the aircraft's turbine engine and the wing. The suspension system transmits the forces generated by the associated turbine engine to the aircraft structure and also serves to route the fuel, electrical, hydraulic and air systems between the engine and the aircraft. [0005] The su...
