Abstract
An aircraft engine pylon aft aerodynamic fairing includes upper spars, transverse stiffening ribs, lower spars and a trailing edge where the upper spars and lower spars join together. In this fairing, a profiled structure is formed according to a profile open to the outside of the fairing. In a first end portion, the profiled structure comes to be enclosed between an end portion of the lower spars and the ends of at least one transverse stiffening ribs flush with the lower spars. This structure extends between the lower spars and the upper spars over a straight central portion inclined relative to the first end portion, and comes in a second end portion flush against a portion of the upper spars, parallel to the first end.

Aft aerodynamic fairing (5) for an aircraft engine (4) attachment pylon (1) comprising upper spars (L1), transverse stiffening ribs (50), lower spars (L3) and a trailing edge (55) where the upper spars (L1) and lower spars (L3) join together in a V configuration at the trailing edge side (55) characterized in that a structural structure (59) is formed in the trailing edge according to a profile open to the outside of the fairing (5), and in that the structure (59) in a first end (E5) comes to be enclosed between a corresponding end portion (P3) of the lower spars (L3) and the ends (5e) of at least one transverse stiffening rib (50) flush longitudinally with lower spars (L3), extends between the lower spars (L3) and the aft upper spars (L1) over a straight central portion (29) inclined relative to the end (E5) thereof and the spars, where this central portion (29) is suitable for receiving the trailing edge (55), and comes at a second end portion (E4) flush against a portion (P1) of the upper spars (L1), parallel to said first end (E5).
