Patent number: 11932410Abstract: A propulsion system for an aircraft includes a rotor and a nacelle fairing that extends around the rotor in relation to an axis. The nacelle fairing includes an upstream portion forming an inlet section of the nacelle fairing as well as a downstream portion, a downstream end of which forms an outlet section of the nacelle fairing. The downstream portion includes radially inner and outer walls, both of which are made of a deformable shape memory material. The wall has independently actuatable piston actuator mechanisms, each actuator mechanism being actuatable independently of the others and being designed to cooperate with means built into an inner surface of the wall to deform the wall in a radial direction in relation to the axis under the effect of a predetermined displacement command.Type: GrantFiled: October 12, 2020Date of Patent: March 19, 2024Assignees: SAFRAN, SAFRAN HELICOPTER ENGINESInventors: Jean-Louis Robert Guy Besse, Ye-Bonne Karina Maldonado

Patent number: 11878786Abstract: A propulsion system for an aircraft, including at least one rotor and a nacelle cowling extending around the at least one rotor, said nacelle cowling being sectored and including at least one sector, which is fixed and sectors which are retractable in the peripheral direction relative to an axis of rotation of the rotor. The retractable sectors include at least a first series of sectors which are telescopically retractable in or on at least one fixed sector and at least a second series of sectors which are telescopically retractable in or on at least one fixed sector, the at least one fixed sector having an angular extent around the axis which is less than or equal to 90°.Type: GrantFiled: December 20, 2019Date of Patent: January 23, 2024Assignees: SAFRAN, SAFRAN AIRCRAFT ENGINES, SAFRAN NACELLESInventors: Jean-Louis Robert Guy Besse, Ye-Bonne Karina Maldonado
