    摘要: The present invention concerns a method for controlling a variable geometry nozzle equipping a turbojet nacelle, said nacelle comprising a variable geometry nozzle (10) comprising a downstream section ended by a plurality of flaps (12) that are mounted movable in such a way as to vary the ejection section of the nozzle. The method according to the invention is remarkable in that it is designed to control the nozzle (10) in a normal mode when the flaps (12) are detected to be in an operational state, or in a degraded mode when at least one flap is detected to be in a blocked state by the detection means, in which degraded mode the method consists of controlling the opening of one or more flaps in the operational state beyond the nominal opening of same in order to compensate for said at least one blocked flap, so as to ensure an opening of the nozzle (10) corresponding to said initial opening control.

    摘要: The invention relates to a thrust reverser (18) for a nacelle (10) of an aircraft turbofan including at least one movable thrust reverser cover (20), a means for locking the cover (20), a variable-exhaust output nozzle (22) which is arranged forming a downstream extension of said cover (20) and which is movable, and at least one actuator (24) which includes an actuator rod (28) suitable for moving the variable nozzle (22) and the movable cover (20), characterised in that the reverser (18) is provided with a resilient coupler (30) comprising a body (32) which is rigidly connected to the thrust reverser cover (20), resilient return means (48) and abutments which are supported by the body (32) of the coupler (30) and which engage with the actuating rod (28) of the actuator (24) such as to resiliently return the nozzle (22) into the neutral position thereof, said return means (48) being calibrated such that, when the cover (20) is unlocked, the return means (48) oppose the relative movement of the actuating rod (28) relative to the cover (20), such as to enable the movement of the assembly consisting of the cover (20) and the nozzle (22), and when the cover (20) is locked, the actuator (24) drives the actuating rod (28) against the return means (48), such as to enable the movement of the nozzle (22).
