Embodiment Construction

[0053]figure 1 An aircraft 1 of the invention is shown.

[0054] The aircraft comprises a fuselage 2 extending longitudinally from a front end 3 to an aft end 4 . In addition, the fuselage 2 extends laterally from the right wing 5 to the left wing 6 and vertically from the bottom 7 to the top 8 .

[0055] The bottom is conventionally provided with landing gear, while the top 8 may carry rotors 9 providing lift and possibly also propulsion. The bottom may comprise a lower section defined in particular by the cabin floor and the outer fuselage envelope.

[0056] The aircraft 1 is provided with the buoyancy system 10 of the invention to be able to land on water.

[0057] Such a buoyancy system 10 is provided with at least two buoyant bodies 15 arranged on each side of the fuselage 2 of the aircraft. Thus, the left floating body 16 is arranged next to the left wing of the aircraft, while the second floating body 17 is arranged next to the right wing of the aircraft.

Abstract

A buoyancy system for an aircraft, the buoyancy system being provided with at least two floats, said buoyancy system including a connection device for each float, each connection device attaching each float to a structure of an aircraft. Each connection device includes at least one stretchable connection and at least one non-stretch connection that are fastened to the float and that are suitable for being fastened to said structure, each non-stretch connection being folded while the float is against the fuselage so as to enable it to be lengthened, each non-stretch connection limiting the amplitude of the movement of the float under the effect of buoyancy thrust, and each stretchable connection exerting a return force on the float.

Description

[0001] Cross References to Related Documents [0002] This application claims priority from French patent application No. 1400277, filed January 31, 2014, the entire content of which application is hereby incorporated by reference. technical field [0003] The invention relates to a buoyancy system for an aircraft and to an aircraft provided with such a buoyancy system. [0004] Thus, the present invention belongs to the technical field of buoyancy systems enabling aircraft to land on water and to float in a stable manner, and more particularly relates to rotorcraft. Background technique [0005] This buoyancy system helps provide buoyancy and stability to the vehicle after it lands on water. The buoyancy system may be used, for example, during a ditching to enable passengers to evacuate the aircraft. In principle, all aircraft carrying out the task of transporting passengers across seas are equipped with such a buoyancy system. [0006] Additionally, certification regula...
