A variable section nozzle for an aircraft nacelle comprising:

• movable doors configured to be displaced between a reduced section position and a larger section position;
• and
• at least one displacement device for displacing the movable doors, each displacement device including actuators and a controller to control the actuators,
• wherein each of the movable doors comprises at least one first guide device and at least one second guide device, the at least one first and second guide devices operable to guide the displacement of the movable doors relative to a fixed structure of the variable section nozzle,
• wherein the at least one second guide device is disposed downstream relative to the at least one first guide device, the at least one first and the at least one second guide devices each providing, at least locally, a curvilinear path,
• wherein the curvilinear path of at least the first guide device includes a concave portion oriented inwardly of the variable section nozzle.
