Abstract:
1. A nacelle for a jet engine, comprising a forward air inlet section, a mid-section intended to surround a jet engine fan, and an aft section equipped with at least one thrust reversal system, comprising: means for deflecting at least part of an air flow of the jet engine, and, at least one cowl mounted translatably along at least one guide rail, in a direction substantially parallel to a longitudinal axis of the nacelle, the movable cowl being able to switch alternately from a closed position in which the cowl provides the nacelle with aerodynamic continuity, and covers the deflection means, to an open position in which the cowl opens a passage in the nacelle and uncovers the deflection means, wherein the aft section is equipped with at least one mechanical inhibition stud being movably mounted on a fixed structure of the aft section in a region of the guide rail such that the stud can move between a retracted position in which the stud is withdrawn from a running track of the guide rail, and allows translation of the movable cowl, and an engaged position, in which the stud forms a stop capable of preventing the movable cowl from sliding in a downstream direction of the nacelle, wherein the movable mechanical inhibition stud is equipped with manual activation means comprising a system of rocker bars.
