Door-closing system for a thrust reverser of an aircraft nacelle

A method for using a closing system for a pair of doors for a thrust reverser of an aircraft nacelle, the doors being diametrically opposed and pivotally mounted such that the doors are pivotable between a direct jet position in which the doors provide aerodynamic continuity of the aircraft nacelle, and a reverse jet position in which the doors open at least one passage in the aircraft nacelle, the closing system comprising:

• a closing actuator for the doors including two first connecting rods, each first connecting rod being configured to be connected to a first lateral edge of each door, the closing actuator being configured to move each door at least towards the direct jet position;
• two sliding members each carrying a second connecting rod configured to be connected to a second lateral edge of each door, the second lateral edge being opposite the first lateral edge, the second connecting rods being configured to be driven by the doors when the closing actuator moves the doors towards the direct jet position so as to displace the two sliding members;
• and a detection device for detecting a defect of one of the first and second connecting rods, the detection device being configured to detect a relative position of the two sliding members in the direct jet position, the method comprising:
• comparing relative positions of the sliding members.

• and a locking system configured to lock the doors in the direct jet position, the method comprising:
• comparing relative positions of the sliding members;
• and
• locking the doors in the direct jet position when the detection device does not detect any offset between the sliding members.
