Abstract: The present disclosure provides a variable section nozzle for an aircraft nacelle having a longitudinal axis. The variable section nozzle includes movable doors and at least one displacement device for displacing the movable doors between a reduced section position and a larger position. The movable doors include at least one first guide device and at least one second guide device, each operable to guide the displacement of the doors relative to a fixed structure of the nozzle. The second guide device is disposed downstream relative to the first guide device and each of the first and second guide devices provide a curvilinear path. In one form, the curvilinear paths are substantially circular and define a circular arc.
