 Appl.No PCT/FR1998/000310 Applicant HISPANO-SUIZA AEROSTRUCTURES Inventor BAUDU, Pierre, André, Marcel
The invention concerns a bypass turbojet thrust reverse system comprising pivoting doors (7a, 7b) integrated in direct jet in the outer wall of the fan air duct (15) and constituting flux deviating obstacles providing thrust reversal. At least two actuators (23) controlling the door (7a, 7b) movements are associated with a synchronising device (19) consisting of an electric motor (20) and its electronic power system (21) and a bezel box (22) connected by a transmission linkage (26) to each actuator (23) respectively.

A bypass jet engine thrust reverser comprising pivoting doors (7) integrated into the outer pod wall in the direct thrust position and pivoted out by a hydraulic cylinder (8) to form deflecting buckets for thrust reversal. An internal upstream panel (20) lines the inner surface of each door (7), and the door (7) and the upstream panel (20) are pivotable about separate respective pivots (27, 28). The door (7) and the upstream panel (20) are joined together via a so-called three-point linkage (30) hinged to a first point (31) on a support (32) secured to the upstream panel (20), to a second point (33) on the door (7), and to a third point (34) at the end of the rod of the control cylinder (8), whereby no opening torque is transmitted to the door (7) in the direct thrust position by the pressure forces exerted on the upstream panel (20).

The invention concerns a method for closing the doors (10) of an aircraft thrust reverser (8) enabling this closure despite the pressure increase of the propulsion air generated by the turbojet engine. This method is characterised in that it comprises the following steps: a) holding the door (10) by its front end (10a) before the door (10) is completely closed; b) pulling the door (10) by its front end (10a) until it is in closed position; c) repeating the tractive force thus produced on the part (8a) of the structure (8) in straight line with the front end (10a) of the door (10). The invention also concerns devices specially designed for implementing the method.
