A variable-section nozzle for an aircraft nacelle includes a deformable portion of which is movable between a narrow section position and a wide section position. In particular, the variable-section nozzle includes piezoelectric actuators and a controller to control the piezoelectric actuators in order to displace the deformable portion between the narrow and wide section positions. The piezoelectric actuators can be disposed on at least one faces of the deformable portion or be disposed end-to-end to form actuating rods.
A variable-section nozzle for an aircraft nacelle, the variable-section nozzle comprising at least one deformable portion which is movable between a narrow section position and a wide section position, the variable-section nozzle comprising:

The present disclosure relates to a nacelle for an aircraft engine, with a variable-section nozzle.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
An aircraft engine nacelle allows channeling external air toward this engine, and providing high-velocity ejection of this air to provide the necessary thrust.
In order that the disclosure may be well understood, there will now be described various forms thereof, given by way of example, reference being made to the accompanying drawings, in which:
FIG. 1 is a perspective view of a nacelle for an aircraft turbojet engine, equipped with a variable-section nozzle in accordance with the present disclosure;
FIG. 2 is an exploded perspective view of a piezoelectric actuator equipping the nacelle of FIG. 1;
The drawings described herein are for illustration purposes only and are not intended to limit the scope of the present disclosure in any way.
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
Referring now to FIG. 1, which shows a nacelle 1 for an aircraft turbojet engine of a longitudinal axis A, equipped with a variable-section nozzle 3 in accordance with the present disclosure.
