Abstract
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.
Claims13
A variable-section nozzle for an aircraft nacelle, at least one deformable portion of which is movable between a narrow section position and a wide section position, and the variable-section nozzle comprising:
- means for displacing said at least one deformable portion between said narrow and wide section positions, wherein said means for displacing comprise piezoelectric actuators and means for controlling said piezoelectric actuators, said piezoelectric actuators being disposed in one of the following manners:
- said piezoelectric actuators are disposed on at least one face of said at least one deformable portion, and
- said piezoelectric actuators are disposed end-to-end to form actuating rods.
