Abstract
A rear engine attachment for an engine of an aircraft which comprises a pylon having a bottom face, the rear engine attachment comprising a first fitting configured to be fixed against the bottom face and having a wall, a second fitting configured to be secured to a structural casing of the engine, two front links and two rear links, which are fixed by one and the same main link point to the wall and by two link points on either side of the second fitting. Such a motorization assembly allows for a reduction of the bulk, in particular at the rear engine attachment, which helps in improving the overall performance of the motorization assembly.
Claims18
A rear engine attachment for an engine of an aircraft which comprises a pylon having a bottom face, the rear engine attachment comprising:
- a first fitting configured to be fixed against the bottom face and comprising a wall which extends in a plane at right angles to a longitudinal axis X and having a front face configured to be oriented towards a front of the aircraft and a rear face configured to be oriented towards a rear of the aircraft,
- a second fitting configured to be secured to a structural casing of the engine, the second fitting extending in a plane at right angles to the longitudinal axis X and having a front face configured to be oriented towards the front of the aircraft and a rear face configured to be oriented towards the rear of the aircraft,
- a front inner link,
- a rear inner link,
- a front outer link, and
- a rear outer link,
- wherein the front inner link has a rear face which is positioned facing a front face of the wall and facing the front face of the second fitting,
- wherein the rear inner link has a front face which is positioned facing a rear face of the wall and facing the rear face of the second fitting,
- wherein the front outer link has a rear face which is positioned facing a front face of the front inner link,
- wherein the rear outer link has a front face which is positioned facing a rear face of the rear inner link,
- wherein the front inner link is fixed by a main link point to the wall and by a first link point and a second link point to the second fitting,
- wherein the front outer link is fixed by the same main link point to the wall and by the same first link point and another second link point to the second fitting,
- wherein the rear inner link is fixed by the same main link point to the wall and by the same first and the same second link points to the second fitting as the front inner link,
- wherein the rear outer link is fixed by the same main link point to the wall and by the same first and the same second link points to the second fitting as the front outer link,
- wherein at each of the link points, the four links and either the first or second fitting, are fixed by a common fixing element extending along an axis parallel to the longitudinal axis X.
