Abstract
The invention relates to a propulsion system () for an aircraft, comprising a rotor () and a nacelle failing () that extends around said rotor in relation to an axis (X) and includes an upstream portion () forming an inlet section (BA) of the nacelle fairing () as well as a downstream portion (), a downstream end () of which forms an outlet section (BF) of the nacelle fairing (); and characterized in that the downstream portion () has a radially inner wall () and a radially outer wall (), both of which are made of a deformable shape memory material, and in that the downstream end () includes pneumatic or hydraulic actuators (') extending in different consecutive angular sectors about said axis (X), each actuator being independently actuatable and being configured to deform, in a direction that extends radially in relation to said axis (X) and is centered angularly in relation to its angular sector, under the effect of a predetermined control pressure.
