METHOD FOR CONTROLLING A VARIABLE GEOMETRY NOZZLE FOR A TURBOJET NACELLE

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.
