  • Patent number: 8814080
    Abstract: An aerodynamic aft fairing of an engine pylon ensuring the mounting of an engine underneath a wing of an aircraft is provided. The aerodynamic aft fairing includes an outer lateral panel and an inner lateral panel assembled together at least by a bottom panel, the bottom panel comprising, on either side of the lateral panels, an extension forming an aerothermic barrier capable of channeling hot air flows leaving the engine. The inner lateral panel and the outer lateral panel are attached to the bottom panel by a first angle bar and a second angle bar, respectively.

  • Patent number: 8336812
    Abstract: An engine attachment for an assembly system configured to be mounted between a rigid structure of an attachment strut of an aircraft engine and an engine. The attachment includes a main body, a rudder bar on an articulated mounting on the main body by a hinge pin, and two thrust absorption rods each with one end connected to the rudder bar. The main body includes a first main brace and a second main brace superimposed on the first brace. The hinge pin is formed by a first portion and a second portion, wherein the first portion is made in one piece with the first brace and the second portion is made in one piece with the second brace. Furthermore, the braces define a stop limit surface configured to limit rotation of the rudder bar.

  • Patent number: 8118252
    Abstract: A rear lower aerodynamic fairing for an attachment device for an aircraft engine, including two side panels assembled together with transverse stiffening inner ribs spaced apart from each other along a longitudinal direction of the fairing, and a heat protection floor to be closely followed by a primary flow of the engine. The floor includes plural floor segments distributed along the direction and non-rigidly bound to each other, and the fairing further includes an assembling mechanism assembling the floor segments, offsetting the latter of the ribs to which are connected the assembling mechanism.
