Thrust reverser for a jet engine, more especially for equipping an aircraft

In combination with an engine including a central body and an outer casing in which are produced a primary flux flow (hot) and a secondary flux flow (cold) by means of a fan for ejection through a singular annular duct provided between the central body and the casing, a thrust reverser for insuring deflection of substantially all of the flows created by the engine and the fan, said casing comprising a fixed forward section and a moveable downstream section which is axially moveable with respect to the central body and said thrust reverser including means for producing a thrust inversion comprising doors moveable from a first, inactive position to a second, thrust reversal position in which the doors extend radially with respect to the annular duct so as to close off the duct and extend outwardly with respect to the casing so as to create a passage in the casing which allows the flux to be deflected radially towards the outside of the annular duct and upstream thereof, said doors forming an intermediate section of the casing which is located between said fixed forward section and said moveable downstream section and which, in the first, inactive position thereof, is co-planar with said upstream and downstream sections;

• exterior links for joining said doors to said downstream section of said casing;
• beams forming extensions of said fixed upstream section of said casing and disposed laterally with respect to said doors;
• fixed axes formed integrally with said beams about which said doors pivot between said inactive position and said thrust reversal position;
• and control means for moving said downstream section of said casing and comprising jacks which are housed in said beam and which extend between said fixed upstream section and said moveable downstream section such that the action of said jacks directly causes the axial movement of said moveable downstream section and, consequently, the pivoting of said doors to said second, thrust reversal position thereof, solely by means of the force exerted by said moveable sections on said links and such that said jacks are permanently disposed outside of the thrust inversion flux.
