Jet engine nacelle having dampers for half-shells
A jet engine nacelle includes an air intake section, a middle section, and an aft section. The aft section is formed from two half-shells rotatably mounted such that they can each be deployed between a working position and a maintenance position under the action of a jack and a telescopic connecting rod each respectively having a first end fastened on the jet engine and a second end fastened in the corresponding half-shell. In particular, the nacelle includes at least one damping member arranged between each telescopic connecting rod and the corresponding half-shell, and the damping member is designed so as to be in a prestressed state when the corresponding half-shell is in the working position and can reduce vibration in the half-shell.
1. A jet engine nacelle comprising:
an air intake forward section;
a mid-section intended to surround a fan of the jet engine;
an aft section formed from at least two half-shells rotatably mounted such that each of said at least two half-shells is opened out between a working position and a maintenance position under an action of at least one jack and at least one telescopic connecting rod each respectively having a first end fastened on the jet engine and a second end fastened in a corresponding half-shell; and
at least one damping member arranged between each of the at least one telescopic connecting rod and said corresponding half-shell, said at least one damping member being be in a prestressed state when the corresponding half-shell is in the working position, said damping member being configured so as to reduce vibrations in the half-shell.
2. The nacelle as claimed in claim 1 , wherein the second end of the at least one jack and the second end of the at least one telescopic connecting rod are fastened in a forward frame that is part of the corresponding half-shell.
3. The nacelle as claimed in claim 1 , wherein the damping member comprises a leaf spring.
4. The nacelle as claimed in claim 3 , wherein the leaf spring has a first end fastened in the corresponding half-shell and a second end pressing on the at least one telescopic connecting rod.
5. The nacelle as claimed in claim 4 , wherein the first end of the leaf spring is fastened in the forward frame.
6. A propulsion assembly, comprising a nacelle as claimed in claim 1 arranged around a jet engine.
7. An aircraft, comprising at least one propulsion assembly as claimed in claim 6 .
