A rear part of an aircraft including a support structure for supporting engines, passing through the fuselage, through first and second openings. The rear part includes a connection structure connecting the support structure to the fuselage, including a first connection mechanism connecting the support structure to a first casing forming the first opening and a second connection mechanism connecting the support structure to a second casing forming the second opening. The first and second connection mechanisms each include at least one blocking element of the support structure, under compression loading by being applied to the casing and to the support structure.

1. A rear part of an aircraft comprising: a fuselage delimiting an inner area of the aircraft;at least two engines;a support structure for the engines, passing through the fuselage at first and second openings formed therein and distributed on either side of a vertical middle plane of the aircraft,
1. A rear part of an aircraft comprising: a fuselage delimiting an inner area of the aircraft;at least two engines;a support structure for the engines, passing through the fuselage at first and second openings formed therein and distributed on either side of a vertical middle plane of the aircraft, the support structure having first and second opposite ends;each of the first and second opposite ends of the support structure protruding outwardly from the fuselage, on either side of the vertical middle plane, respectively, and supporting one of the engines; andfastening means connecting the support structure to the fuselage, comprising first fastening means connecting the support structure to a first casing forming the first fuselage opening and second fastening means connecting the support structure to a second casing forming the second fuselage opening;wherein the first fastening means comprises at least one blocking element of the support structure, under compression loading while bearing on the first casing, and on the support structure, and wherein the second fastening means comprises at least one blocking element of the support structure, under compression loading while bearing on the second casing, and on the support structure. 2. The rear part of an aircraft according to claim 1, wherein each of the first and second fastening means comprises at least two blocking elements of the support structure, under compression loading along two separate directions, respectively. 3. The rear part of an aircraft according to claim 1, wherein each blocking element, under compression loading, bears on the support structure and/or on its associated casing, via a damping member. 4. The rear part of an aircraft according to claim 3, wherein the damping member is made from an elastically deformable polymer material. 5. The rear part of an aircraft according to claim 1, wherein each blocking element includes means for adjusting pacing between its two bearing surfaces respectively bearing on the support structure and on the respective casing. 6. The rear part of an aircraft according to claim 1, wherein each blocking element assumes a form of a compression rod supporting two opposite bearing surfaces. 7. The rear part of an aircraft according to claim 1, wherein each of the first and second fastening means comprises blocking elements bearing on at least two faces of the support structure, and on at least one secondary damping member inserted between another face of the support structure, and the respective secondary casing. 8. The rear part of an aircraft according to claim 1, wherein the support structure and the first and second casings each have four faces substantially forming a quadrilateral in section along the associated middle opening plane, and wherein each of the first and second fastening means comprises blocking elements bearing on two attached faces of the support structure, and a secondary damping members inserted between the other two attached faces of the support structure, and the respective casing. 9. The rear part of an aircraft according to claim 1, wherein the fastening means further comprises at least one effort recovery connecting rod, whereof a first end is mounted on the support structure, and an opposite second end of which is mounted on the fuselage, spaced away from the first and second openings. 10. The rear part of an aircraft according to claim 9, wherein the effort recovery connecting rod is inclined relative to a vertical direction of the aircraft, seen along a longitudinal direction thereof.
