The invention concerns a thrust reverser for a jet engine, of the type having swing doors (6) pivoting about fixed transverse pivots (7) secured to the rear end of flanges extending in line with pipe of the engine. According to the invention, each door (6) is borne by a connecting piece (10) offset
The invention concerns a thrust reverser for a jet engine, of the type having swing doors (6) pivoting about fixed transverse pivots (7) secured to the rear end of flanges extending in line with pipe of the engine. According to the invention, each door (6) is borne by a connecting piece (10) offset towards the front with respect to a transverse plane passing through the pivot axis and orthogonal to the longitudinal axis of the door. Furthermore, the fairing (4a, 4b) extends as far as the rear end of the flanges, the said fairing and each door (6) being arranged, on the one hand, so as to cover completely the flanges in the folded position of the said door, and, on the other hand, to enable each door (6) to be brought into its deployed position without any interference between the said fairing and door.

[ What is claimed is:] [1.] A thrust reverser for a jet engine, notably that of an aircraft, comprising a pipe extended by flanges, and a fairing covering the pipe and the flanges, said thrust reverser having:at least one door having outer and inner surfaces and provided with a rear end face having
[ What is claimed is:] [1.] A thrust reverser for a jet engine, notably that of an aircraft, comprising a pipe extended by flanges, and a fairing covering the pipe and the flanges, said thrust reverser having:at least one door having outer and inner surfaces and provided with a rear end face having a trailing edge extending along a plane which is oblique with respect to the longitudinal axis of this door, each of said doors being disposed in line with the pipe and borne by connecting pieces pivoting about transverse pivots fixed to the flanges, towards the rear end of the latter,pivoting means for each door, arranged so as to cause it to pivot about the axis of said pivots between two extreme positions:a folded position in which each door lies in line with the pipe so as to have, on the outer surface of the door, the same profile as the fairing, and to form on the inner surface of the door, with the flanges, an extension of the pipe,a deployed position in which each door is disposed in such a way that its rear face is substantially parallel to the longitudinal axis of the engine,wherein each connecting piece being integral with said door and including a connecting arm fixed to the flange, each connection piece includes a structural joint offset towards the front relative to a transverse plane passing through the fronts of the pivots of the doors and orthogonal to the longitudinal axis of the door,the fairing extends as far as the rear end of the flanges and is connected to the flanges to obtain a bearing plate of minimal thickness when the doors are in their deployed position, said fairing and each door being arranged, on the one hand, so as to cover completely the flanges in the folded position of the said door, and, on the other hand, to enable each door to be brought into its deployed position completely clearing the space between the internal flange and the external fairing without any interference between said fairing and door.
