The invention proposes a process for closing aircraft thrust reverser (8) doors (10), making it possible to close these doors in spite of the increase in propulsive air flow pressure produced by the turbine engine. This process is remarkable in that it comprises the following operations: (a) catching the door (10) by its leading edge (10a) before the door (10) is completely closed; (b) pulling the door (10) by its leading edge (10a) until it reaches the closed position; (c) re-exerting the pull force thus produced on the section (8a) of the housing (8) facing the leading edge (10a) of the door (10). The invention also proposes specially designed apparatus for implementing this process.

L'invention propose un procédé de fermeture des portes (10) d'un inverseur de poussée (8) pour aéronef permettant d'effectuer cette fermeture malgré l'augmentation de la pression du flux d'air de propulsion produit par le turbomoteur. Ce procédé est remarquable en ce qu'il comporte les opérations suivantes: a) Attraper la porte (10) par son extrémité avant (10a) avant la fermeture complète de la porte (10), b) tirer la porte (10) par son extrémité avant (10a) jusqu'à la position fermée, c) reprendre l'effort de traction ainsi produit sur la partie (8a) de la structure (8) en regard de l'extrémité avant (10a) de la porte (10), l'invention propose aussi des dispositifs spécialement conçus pour mettre en oeuvre le procédé.
