Claim 0:
1. A propulsion system for an aircraft, comprising at least one rotor and a nacelle fairing extending around said at least one rotor with respect to an axis of rotation of said rotor, the nacelle fairing comprising an upstream section forming an inlet cross-section of the nacelle fairing and a downstream section, a downstream end of the downstream section forming an outlet cross-section of the nacelle fairing, wherein the downstream section comprises a radially internal wall and a radially external wall made of a deformable shape-memory material, the radially external wall comprising a plurality of actuator mechanisms with at least one cylinder, each actuator mechanism being operable independently of the other actuator mechanisms and being configured to cooperate with means embedded in an internal surface of the radially external wall so as to deform the radially external wall in a radial direction with respect to the axis of rotation, under the effect of a predetermined displacement command.
