An aircraft having a sponson extending substantially transversely relative to a main body of the fuselage of the aircraft and substantially perpendicularly relative to a vertical anteroposterior plane of symmetry P of the main body of the fuselage when the aircraft is standing on a horizontal support, the sponson including a notch locally reducing a cross-section of the sponson in a connection zone of the sponson, the connection zone being suitable for being arranged in the immediate proximity of the main body of the fuselage of the aircraft from which the sponson emerges transversely, the notch being open at least to a front outside face and to a top outside face of the sponson and being suitable for receiving a bottom portion of a sliding side door when in its open position.

A rotorcraft () having: a lift rotor (); a wing () extending from a first end () carrying a first propulsive propeller () to a second end () carrying a second propeller (); landing gear (); and a tail (). The rotorcraft () is provided with two fuselages () secured to said wing () between said first and second propulsive propellers () in such a manner as to present an inter-fuselage space () having no propeller between said fuselages (), each fuselage () including at least one undercarriage of said landing gear ().

Twin-fuselage rotorcraft

A fuselage structure for a rotorcraft (), the structure comprising load-bearing members including middle frames () carrying a top floor () and a middle floor (). The middle floor () internally partitions the fuselage into two compartments (), including a cabin-forming top compartment () and a bottom compartment () having an open bottom () leading to the outside via the bottom face of the fuselage. The middle floor () provides a loading plane in the top compartment () having a false-floor () made up of interchangeable slabs () fitted out in a variety of ways. The middle floor () also forms an anchor member from which equipment () for suspending can be suspended, which equipment is accessible from outside the fuselage through said open bottom ().

An energy absorber system () provided with a shock absorber () extending from a first end () suitable for being connected to a rocker arm () of an undercarriage () housed in a wheel bay (), towards a second end (). In addition, the system includes a fitting () connected to said second end (), and guide means () for guiding said fitting () in translation that is suitable for being fastened to a flank (&#x2033;) of said wheel well (), said system () including deformable energy absorber means () fastened to said fitting () and suitable for being fastened to a structure (&#x2033;) of said bay () and also to fusible retention means () suitable for fastening said fitting () to said flank (&#x2033;), said fusible retention means () rupturing from a predetermined threshold in order to allow said fitting () to move under guidance from said guide means () so as to deform said energy absorber means ().
