Jet engine nacelle with dampers for half-shells

Abstract

The present invention relates to a jet engine nacelle ( 1 ) comprising an aft section ( 8 ) formed from at least two half-shells ( 9 ) rotatably mounted such that they can each be deployed between a working position and a maintenance position under the action of a telescopic ram ( 11 ) and of a telescopic connecting rod ( 12 ) each respectively having a first end ( 13, 14 ) fastened in or on the jet engine and a second end ( 16, 17 ) fastened in the corresponding half-shell, characterized in that it comprises at least one damping member ( 19 ) arranged between each connecting rod and said half-shell, said damping member being designed such that it is in a prestressed state when the half-shell is in the working position.

1 . A turbojet engine nacelle comprising
 a front air inlet section,   a middle section intended for surrounding a blower of the turbojet engine, and   a rear section formed from at least two half-parts mounted movably in terms of rotation so as each to be capable of being deployed between an operating position and a maintenance position under action of at least one jack and of at least one telescopic rod capable of being locked in a deployed position, and each having respectively a first end fastened to the turbojet engine and a second end fastened in the corresponding half-part,   wherein the jacks are associated with one or more actuating means equipped with at least one device limiting an active torque during a retraction phase of said jacks.   
     
     
         2 . The nacelle as claimed in  claim 1 , wherein the actuating means are equipped with a device limiting the active torque during opening. 
     
     
         3 . The nacelle as claimed in  claim 2 , wherein the device limiting the active torque during closing and the device limiting the active torque during opening are combined in a single double-acting device. 
     
     
         4 . The nacelle as claimed in  claim 3 , wherein the torque-limiting device possesses different calibration values for opening and closing. 
     
     
         5 . The nacelle as claimed in  claim 1 , wherein the jacks are jacks actuated by means of at least one electric motor. 
     
     
         6 . The nacelle as claimed in  claim 6 , wherein the torque-limiting device is mounted on a driveshaft of the electric motor. 
     
     
         7 . The nacelle as claimed in  claim 1 , wherein the torque-limiting device comprises at least one ball-type torque-limiting device. 
     
     
         8 . A propulsive assembly comprising a nacelle as claimed in  claim 1  which is arranged around a turbojet engine. 
     
     
         9 . An aircraft comprising at least one propulsive assembly as claimed in  claim 8 .
