An aircraft for the transport of cargo and/or passengers, comprising a fuselage extending in longitudinal direction and having an upper deck, in particular main deck, and a lower deck separated from each other by a floor, wherein the fuselage comprises a barrel section with a cross-sectional profile for accommodating cargo and/or passengers, wherein the cross-sectional profile is essentially formed by several, in particular four, circular arc sections, which have radii (R1, R2, R3) with centers (M1, M2, M3′, M3″) differing from one another, so that the cross-sectional profile is designed in such a way that cargo items with different size dimensions, in particular cargo containers with different height and width dimensions, can be accommodated in the upper deck and the lower deck.

An aircraft having a fuselage having a pressurized upper space above the floor and a lower space beneath the floor, a wing, a hollow support stay fixed between the lower space level of the fuselage and the wing, an electric motor propeller propulsion system fixed beneath each wing, the output shaft of the motor driving a propeller in rotation, a production system having a fuel cell producing electrical energy supplying the electric motor with electricity via electrical conductors, a hydrogen reservoir fixed in the lower space, and a hydrogen inlet pipe feeding hydrogen from a hydrogen reservoir to the production system, wherein the hydrogen inlet pipe extends through the interior of the support stay. The electrical conductors or the hydrogen pipes pass through the stays on the outside of the fuselage and therefore at a distance from the passengers and the electronic systems of the aircraft.

A multifunctional container system for producing a container for a cargo compartment of an aircraft includes a first lateral container component, which forms a first lateral surface of the container that is at least partially beveled, a first lower resting surface having first fastening devices and a first top side, a second lateral container component, which forms a second lateral surface of the container that is at least partially beveled, a second lower resting surface having second fastening devices and a second top side, and a floor cladding. The cladding is selectively positionable between the first resting surface and the second resting surface, which enclose a continuous gap to each other and comprise a predetermined distance to each other and to create a protrusion that faces away from the first and second top side. The protrusion extends into a recess of a floor in a cargo compartment.

A hybrid fuel airplane and methods are presented. A cryogenic fuel is transferred to an airplane propulsor from an airplane fuel system comprising a cryogenic fuel tank and a jet fuel tank. The cryogenic fuel tank conforms to an outer mold line and carries a cryogenic fuel, and is located in a portion of the airplane body while not extending beyond the outer mold line. The jet fuel tank carries a jet fuel and is located in an airplane wing, or an airplane body, or both. A dynamic aircraft load is born on the cryogenic fuel tank, and the airplane propulsor is operated using the cryogenic fuel to generate thrust for the hybrid fuel airplane. An aerodynamic lift is generated using the airplane wing coupled to the airplane body.

Passenger accommodation systems are described. An example passenger accommodation system can be disposed in an aircraft and can include a passenger seating deck, a plurality of passenger seats disposed within the passenger seating deck, and a partition wall disposed within the passenger seating deck so as to separate the plurality of passenger seats into a first set of passenger seats and a second set of passenger seats. The partition wall can be aligned with a longitudinal axis extending in the direction of travel of the aircraft. Movement of passengers between the first set of seats and the second set of seats may not impeded by the partition wall.

An aircraft includes a passenger cabin having a floor, a cargo compartment below the floor, a first access unit for accessing the cargo compartment from the passenger cabin, the first access unit being located on the floor and a utility space module arranged in the cargo. At least one part of the cargo compartment includes a first lateral half and a second lateral half in relation to a longitudinal axis of the aircraft; the lateral halves form the part of the cargo compartment. The utility space module includes a utility space cross-section in a direction normal to the longitudinal axis, which is dimensioned such that it conforms to a cross-section of one of the lateral halves of the cargo compartment. Further, the utility space module is placed exclusively in the first lateral half or the second lateral half of the cargo compartment directly below the first access unit.

A passenger cabin for a vehicle has an upper passenger deck with an upper arrangement of seats, a lower passenger deck with a lower arrangement of seats, an upper floor for the upper passenger deck arranged between the upper passenger deck and the lower passenger deck, and a lower floor for the lower passenger deck delimiting the lower passenger deck. The upper floor has a central hump region extending along a longitudinal axis of the passenger cabin at least in regions and above which the upper arrangement of seats is arranged, and two side regions adjacent to the hump region. The central hump region is raised relative to the side regions. The lower floor has a lower gangway, wherein the at least one lower arrangement of seats is arranged below the side regions of the upper floor, and the lower gangway is arranged below the central hump region.

A vehicle passenger cabin has a holding structure having multiple load introduction points, a multiplicity of support structure parts to be attached to the load introduction points, a lower base for delimiting a lower passenger deck, and a multiplicity of furnishing components to be fastened to the support structure parts. The holding structure has laterally on both sides one floor overhang as a lower delimitation of an upper passenger deck, extending from a laterally outer region of the holding structure radially inwards and at a distance vertically from the lower base. The structure parts are at least regionally curved or bent and are connected at an upper end and at a lower end to an upper and a lower load introduction points, respectively. The structure parts have a first receiving surface for receiving one of the furnishing components, which first receiving surface adjoins the floor overhang radially on the inside.

A modular lower lobe passenger rest cabin includes passenger rest compartments oriented longitudinally along the roll axis and laterally along the pitch axis. Partial passenger rest compartments are defined by the modular lower lobe passenger rest cabin such that when two modular lower lobe passenger rest cabins are installed in a cargo deck of an aircraft, the partial passenger rest compartments define a single passenger rest compartment or aisle from space that would otherwise be insufficient for the purpose.

An aircraft includes a fuselage, having a crown section and a keel, a first passenger cabin, having a first floor, located in an aft portion the fuselage, and a first cargo deck, located below at least a portion of the first passenger cabin. A forward split level cabin including an upper second cabin having a second floor above the level of the first floor, and a lower third cabin beneath the upper second cabin and having a third floor below the level of the first floor. A second cargo deck is located in the forward portion of the fuselage and beneath at least a portion of the lower third cabin. The crown section has a substantially constant cross-sectional shape fore-to-aft above the first passenger cabin and the split level cabin.
