Abstract

An assembly including a wing with a pressure-side panel and a suction-side panel through which two bores pass, an engine pylon including a blade with three bores and two fastening lugs, each of which has a sixth bore, two first shackles fastened between the blade and the suction-side panel, two second shackles fastened between the blade and the suction-side panel and two fittings, which are fastened beneath the pressure-side panel and each have a female clevis for housing a fastening lug therein.

First claim

The invention claimed is:

1. An assembly for mounting a propulsion system having a vertical median plane on an aircraft, said assembly comprising:
a wing with a front spar, a suction-side panel and a pressure-side panel, which are fastened at an upper portion of the front spar and at a lower portion of the front spar, respectively, wherein a fourth bore and a fifth bore pass vertically through the suction-side panel,
an engine pylon comprising a primary structure, a blade, which is secured to the primary structure and extends to the rear and in an upper portion of the primary structure, and two starboard-side and port-side fastening lugs, which are secured to the primary structure and extend to the rear and along sides of the primary structure, wherein a first bore, a second bore and a third bore pass vertically through the blade, wherein a sixth bore passes horizontally through each fastening lug,
two first shackles arranged vertically on either side of the blade and of the suction-side panel, wherein a first bore in each first shackle is aligned so as to be coaxial with the first bore in the blade, with a pin inserted into the two first bores, wherein a second bore in each first shackle is aligned so as to be coaxial with the fourth bore in the suction-side panel, with a pin inserted into the second and fourth bores,
two second shackles arranged vertically on either side of the blade and of the suction-side panel, wherein a first bore in each second shackle is aligned so as to be coaxial with the second bore in the blade, with a pin inserted into the first and second bores, wherein a second bore in each second shackle is aligned so as to be coaxial with the third bore in the blade, with a pin inserted into the second and third bores, wherein a third bore in each second shackle is aligned so as to be coaxial with the fifth bore in the suction-side panel, with a pin inserted into the third and fifth bores, and
a starboard-side fitting and a port-side fitting, which are fastened beneath the pressure-side panel and have, respectively, a starboard-side female clevis in which the starboard-side fastening lug is inserted and a port-side female clevis in which the port-side fastening lug is inserted, wherein a seventh bore passes through each female clevis, an axis of said seventh bore coaxial with an axis of the sixth bore in the fastening lug inserted therein, and wherein a pin is inserted into the seventh and sixth bores.

2. The assembly according to claim 1 , wherein the suction-side panel comprises a plate that is secured to the suction-side panel and wherein the fourth and fifth bores in the suction-side panel are formed in said plate.

3. An aircraft comprising:
a propulsion system and
the assembly according to claim 1 , wherein the propulsion system is fastened to the engine pylon.
