Abstract:
A thrust reverser for a turbojet having an outer cowling surrounding a gas ejection duct, said thrust reverser comprising a fixed structure including longitudinal spars delimiting passages between said spars in an annular section of said cowling, and a plurality of doors mounted to move between an inactive position occupied during forward thrust operation of said turbojet wherein said doors close off said passages and constitute part of said outer cowling, and a reverse thrust position wherein said doors at least partially close off said ejection duct and deflect the gaseous jet toward said passages, wherein there is provided, between two adjacent doors of said thrust reverser, a locking system allowing substantially simultaneous opening of said two doors, said locking system comprising, for each of said two doors, at least one hook mounted on said fixed structure so that it can pivot between a door locking position and an unlocked position, at least one olive secured to each of said two doors for engaging and pivoting said hooks during opening or closing movement of said doors, and a mechanical linkage device rotationally interconnecting the hooks of said two doors so as to prevent the unlocking of one door if the other door is closed.
