Rear part of an aircraft comprising a structure for supporting engines, extending through the fuselage and connected thereto by at least one connecting rod
A rear part of an aircraft including a support structure for supporting engines, extending through the fuselage, through a first opening and a second opening. A connection structure connects 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 connection structure also includes at least one effort recovery connecting rod, the first end of which is mounted on the support structure and the opposite end is mounted on the fuselage, at a distance from the first and second openings.
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; and
fastening 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 fastening means further comprises at least one effort recovery connecting rod whereof a first end is mounted on the support structure, and the opposite end of which is mounted on the fuselage, spaced away from the first and second openings.
2. The rear part of an aircraft according to claim 1 , wherein the effort recovery connecting rod is inclined relative to a vertical direction of the aircraft, seen along a longitudinal direction thereof.
3. The rear part of an aircraft according to claim 1 , wherein two effort recovery connecting rods are provided, arranged symmetrically relative to the vertical middle plane of the aircraft.
4. The rear part of an aircraft according to claim 3 , wherein the support structure substantially forms a V, and the two effort recovery connecting rods together substantially form an upside-down V relative to that of the support structure.
5. The rear part of an aircraft according to claim 3 , wherein the opposite ends of the two connecting rods are mounted substantially at a same point on the fuselage, the point belonging to the vertical middle plane of the aircraft.
6. The rear part of an aircraft according to claim 4 , wherein the opposite ends of the two connecting rods are mounted substantially at a same point on the fuselage, the point belonging to the vertical middle plane of the aircraft.
7. The rear part of an aircraft according claim 1 , wherein each effort recovery connecting rod is mounted articulated at its ends.
8. The rear part of an aircraft according to claim 1 , wherein each effort recovery connecting rod is mounted above the support structure.
9. The rear part of an aircraft according to claim 1 , wherein at least one effort recovery connecting rod includes a resonator.
10. The rear part of an aircraft according to claim 1 , wherein at least two effort recovery connecting rods are provided articulated on a plate, itself articulated on the support structure or on the fuselage.
11. The rear part of an aircraft according to claim 1 , wherein the support structure includes first and second half-structures respectively passing through the first and second openings of the fuselage, the first and second half-structures being assembled to each other so that they can be disassembled within the inner area.
