Abstract
Official abstract text for this publication.
A front engine attachment system for an engine having an engine pylon with a nose having a male clevis and a cylindrical stud, two links that are fastened to the engine by a second ball-joint connection about a second axis, a first shaft establishing a first ball-joint connection of the links to the male clevis about a first axis, wherein the first axis and the second axis are in the same vertical plane, and wherein the cylindrical stud is mounted so as to be able to move, via an annular linear connection, with respect to the front casing.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A front engine attachment system for an engine of an aircraft, the front engine attachment system having a vertical median plane and comprising: an engine pylon having, at a front part, a nose having a male clevis and a cylindrical stud that is cylindrical about a vertical axis and configured to be mounted so as to move, via an annular linear connection, about the vertical axis with respect to a front casing of the engine, two links, which are configured to be fastened to the front casing by a second ball-joint connection about a second axis perpendicular to the vertical median plane, the two links being arranged on either side of the male clevis, and a first shaft, which is perpendicular to the vertical median plane and forms a first ball-joint connection of the two links to the male clevis about a first axis, wherein the first axis and the second axis are in the same vertical plane perpendicular to the vertical median plane. 2 . The front engine attachment system according to claim 1 , wherein the first axis is arranged towards a rear of the vertical axis. 3 . The front engine attachment system according to claim 1 , wherein each link comprises two adjoining links. 4 . The front engine attachment system according to claim 1 , wherein the nose comprises two fittings that are fastened to one another, and wherein the cylindrical stud comprises two half-cylinders adjoining the vertical median plane, wherein each half-cylinder belongs to one of the fittings of the nose. 5 . The front engine attachment system according to claim 1 , wherein the first shaft comprises a first peripheral shaft, which is hollow, and a first inner shaft, fitted within the first peripheral shaft. 6 . An aircraft comprising: an engine with a front casing and the front engine attachment system according to claim 1 , wherein the links are fastened to the front casing by the second ball-joint connection, and wherein the cylindrical stud is mounted to move, via the annular linear connection, about the vertical axis with respect to the front casing.
