Assembly of a pylon with a wing of an aircraft
An assembly of a pylon and of a wing of an aircraft, the pylon including a primary structure with a rear face and an upper spar. The assembly includes a rear fastening system including a pair of vertical shackles articulated between the rear face of the primary structure and a first shoe fastened to the wing, wherein the shackles are fastened to the primary structure by a clevis-type connection, and a pair of transverse shackles articulated between the rear face of the primary structure and a second shoe fastened to the wing, wherein the shackles are fastened to the primary structure by a clevis-type connection. With such an assembly, the bulk of the rear fastening system is reduced.
1. An assembly of a pylon and of a wing of an aircraft,
the pylon comprising:
a primary structure that extends from front to rear along a longitudinal axis and that is formed as a box with a rear face and an upper spar forming an upper face of the box,
a longitudinal median plane separating the primary structure into two parts, left and right,
the assembly comprising:
a front fastening system configured to fasten the pylon to the wing, which front fastening system is arranged on the upper face of the box halfway along the primary structure,
a rear fastening system configured to fasten the pylon to the wing, which rear fastening system is arranged at the rear of the primary structure, and
an intermediate fastening system for fastening the pylon to the wing, which intermediate fastening system is arranged on the upper face of the box between the front and rear fastening systems,
the rear fastening system comprising:
a pair of vertical shackles mounted to be articulated between the rear face of the primary structure and a first shoe fastened to the wing, wherein the vertical shackles are fastened to the primary structure by a clevis-type connection with a pin oriented transversely with respect to the pylon, and
a pair of transverse shackles mounted to be articulated between the rear face of the primary structure and a second shoe fastened to the wing, wherein the transverse shackles are fastened to the primary structure by a clevis-type connection with a pin oriented longitudinally with respect to the pylon.
2. The assembly according to claim 1 , wherein the transverse shackles of the pair of transverse shackles are fastened to the rear face by a second fitting fastened to the rear face and sandwiched between the transverse shackles of the pair of transverse shackles.
3. The assembly according to claim 1 , wherein the vertical shackles of the pair of vertical shackles are fastened to the rear face by a first fitting fastened to the rear face and sandwiched between the vertical shackles of the pair of vertical shackles.
4. The assembly according to claim 2 , wherein the transverse shackles of the pair of transverse shackles are fastened to the rear face by a second fitting fastened to the rear face and sandwiched between the transverse shackles of the pair of transverse shackles.
