Abstract: A buoyancy system (10) for an aircraft (1), the buoyancy system (10) being provided with at least one inflatable float (15). The buoyancy system (10) has at least one inflator (25) and at least one actuator (30) interposed between the inflator (25) and a float (15), the actuator (30) having a cylinder (35) and a rod (40) partially received in the cylinder (35). The rod (40) is secured to a piston (50) defining a first chamber (61) within the cylinder (35) and in fluid flow communication with the inflator (25), and a second chamber (62) within the rod (40) and in fluid flow communication with the float (15), and the piston (50) has a channel (63) to put the first chamber (61) into fluid flow communication with the second chamber (62), the deployment device (20) having a shutter (70) for shutting the channel (63).

Abstract: An aircraft (1) having an airframe (2) extending along an anteroposterior plane of symmetry (P1) in elevation transversely separating a first side (11) of said aircraft (1) from a second side (12) thereof, said aircraft (1) being provided with hoist means (20) including a winch (21) provided with a drum for winding a hoist cable (22), said hoist means (20) including a beam (30) for guiding said cable, said beam (30) extending from a first end (31) constituting an inlet end for said cable (22) to a second end (32) constituting an outlet end for said cable (22). The hoist means (20) have a counterweight (23), said counterweight including said winch (21) that is fastened to said first end (31), said second end (32) being located on said second side (12) while said winch (21) and said first end (31) are located on said first side (11).
