Description

The invention relates to an aircraft fuselage and an aircraft, preferably a passenger aircraft, particularly preferably a business jet ("business jet" or "VIP jet") with a plane fuselage of this type.

The fuselage is known to be a main assembly of an aircraft. It connects all other components of an aircraft, such as structure and tail, the nose gear and if it is not arranged on the wings, also the main landing gear. The aircraft fuselage of a passenger aircraft includes the cockpit, the passenger cabin, and the payload space. The passenger cabin usually occupies the largest portion of the interior volume of the aircraft fuselage in a passenger aircraft. The configuration of the passenger cabin within the fuselage typically depends on the intended use of the aircraft and the specifications of the owner. Today, passenger cabins for business jets or VIP jets are typically designed for the transport of several people, typically 5 to 20 people, who place particularly high demands on individual flexibility, comfort and, in particular, confidentiality.

The required structural strength is provided to the fuselage by its load-bearing fuselage structure, which absorbs loads acting on the fuselage and which must be designed in accordance with the requirements of the relevant approval authorities. These loads include forces introduced from the parts attached to the fuselage (structure, tail, chassis, engines) and also forces by the masses of the payload (persons / payload) and the aggregates, which are arranged in its interior. The aircraft fuselage structure can be different depending on the design, for example, scaffolding construction, shell construction, half shell construction, etc. For example, in the (half) shell construction, in addition to stringers and frames, the outer skin / planking is also used as the supporting part of the aircraft fuselage structure. In the present context, the term "aircraft fuselage structure" without limitation to a specific type of production of the fuselage generally refers to the supporting structure of the aircraft fuselage.

The corresponding passenger cabin installations inside the fuselage are now attached to the supporting fuselage structure. Room divisions or room partitions in the passenger cabin are typically made by means of curtains or lightweight walls. Aircraft hulls or passenger cabins of today's business jets and VIP aircraft incorporated therein are structured in their architecture in such a way that only a single area of spatial confidentiality exists; H. there is no possibility to acoustically, optically and electronically separate sections of the passenger cabin in such a way that two or more confidentiality zones which are sufficiently isolated from each other are available within the passenger cabin.

A disadvantage, therefore, is that today's designs of the fuselage or the passenger cabin installed therein high confidentiality requirements, such as privacy, optical shielding, etc. do not meet, so that in business jets today typically travel on a flight only people who belong to a circle of trust d. H. For example, persons of a company or a department or a working group who, for example, have no fear of industrial espionage. For the use of business jets, for example, between two major cities, this means that persons of different confidentiality would each have to take their own jet, resulting in correspondingly increased costs and a reduced utilization of the individual jet on the one hand and a higher environmental impact of noise and emissions on the other hand.

As evidenced by countless studies, further globalization of the economy is driving demand for business travel jet aircraft to continue to grow. Since the use of business jets is very expensive, these aircraft could be used more economically and thus attractively if business trips of several groups of people, each forming a confidentiality circle, could be bundled in one plane for one flight. For example, a study showed that supersonic business jets can be used economically and at attractive ticket prices if the supersonic business jet seating capacity can be optimized.

It is therefore the object of the present invention to further develop an aircraft fuselage, in particular a fuselage for a business aircraft, in such a way that the aircraft fuselage allows a largely isolated accommodation of at least two groups of persons, each of which belongs to a circle of trust.

The invention results from the features of the independent claims. Advantageous developments and refinements are the subject of the dependent claims. Other features, applications and advantages of the invention will become apparent from the following description, as well as the explanation of embodiments of the invention, which are illustrated in the figures.

The task is solved with a fuselage of a passenger plane, which is characterized characterized in that at least two passenger cabin modules spaced apart from a supporting fuselage structure are arranged within the aircraft fuselage, wherein the passenger cabin modules each have a load-bearing cabin module structure, and the cabin module structure is respectively connected via damping means to the fuselage structure, wherein the damping means each a structure-borne sound transmission reduce or eliminate between the respective passenger cabin module and the aircraft fuselage structure.

With the arranged in the fuselage at least two passenger cabin modules, it is possible to create at least two separated, acoustically optimally isolated confidentiality areas in the interior of the fuselage. The acoustic insulation of the passenger cabin modules is carried out according to the invention by the structure-borne noise transmission between the respective passenger cabin module and the aircraft fuselage structure respectively reducing or suppressing damping means. For further acoustic insulation, each passenger cabin module preferably has an acoustic insulation which prevents sound transmission from within the passenger cabin module to the outside of the passenger cabin module and vice versa. The acoustic insulation may in this case be arranged on an inner side, on an outer side or on both sides of the cabin module structure. Corresponding insulating materials are known to the person skilled in the art.

Each of the passenger cabin modules preferably has at least one cabin module door and a plurality of windows, the aircraft fuselage having corresponding fuselage doors and fuselage windows, and wherein the passenger cabin modules each extend from outside the passenger aircraft via the corresponding fuselage - / cabin module doors are accessible. If only two passenger cabin modules are integrated in the aircraft fuselage, then the corresponding aircraft fuselage / cabin module doors of the first passenger cabin module are preferably on one side of the fuselage and the corresponding aircraft fuselage / cabin module doors of the second passenger cabin module on the opposite side arranged the fuselage. Thus, it can be ensured as far as possible that the passengers who travel in the first passenger cabin module and the passengers who travel in the second passenger cabin modules do not see each other immediately when boarding or deboarding the passenger aircraft.

A preferred embodiment of the fuselage according to the invention is characterized in that the fuselage is formed pressure-tight in closed fuselage doors, d. H. that the aircraft fuselage is designed as a pressure hull or pressurized cabin. In this case, the individual passenger cabin modules need not be designed as respective pressure cabin.

Another preferred development of the aircraft fuselage according to the invention is characterized in that the passenger cabin modules with closed cabin module doors pressure-tight, d. H. each are each designed as a pressurized cabin. In this variant, the aircraft fuselage for security reasons in addition as a pressurized cabin (eg. As a partial pressure cabin, which maintains a cabin internal pressure of, for example, 15,000-20,000 ft), but this is not required.

The passenger cabin modules are furthermore preferably embodied such that no visual visual contact can arise between passengers in different passenger cabin modules. This means that the walls of the passenger cabin modules consist of an optically opaque material. In addition, each passenger cabin module preferably has a screen that electrically and / or magnetically shields the passenger cabin module from its surroundings. Thus, for example, it can be prevented that electromagnetic signals pass from a passenger cabin module into another passenger cabin module and can therefore be eavesdropped.

Further preferably, the passenger cabin modules do not have a connecting passage connecting the respective passenger cabin modules or a direct connection of the passenger cabin modules. Thus, neither passengers nor on-board personnel can get from one passenger cabin module to another passenger cabin module. Required cabin crew travel in these cases in each passenger cabin module.

Further preferably, none of the passenger cabin modules has access to the cockpit of the passenger aircraft. Thus, there is no danger that passengers of the aircraft can hijack the aircraft. What a significant contribution to aviation safety.

A preferred development of the aircraft fuselage according to the invention is further characterized in that the arranged in the fuselage passenger cabin modules each autonomous means for power supply and / or means for air conditioning and / or means for sanitary supply and / or means for separate communication with the cockpit of the passenger plane and the outside world and / or means for water supply have. Thus, for example, for power supply. each serve a fuel cell, for air conditioning can each be provided a separate air cleaning and Temperierungssystem, the plumbing and water supply can be done per passenger cabin module in its own closed system, each passenger cabin modules via separate communication devices (encrypted satellite connection, VHF-HF Communication facilities etc.). The autonomously operating previously mentioned means make possible a correspondingly separate supply of the passenger cabin modules. They are controllable from inside the passenger cabin modules. With this separation of the system supply of the individual passenger cabin modules, a largely maximum confidentiality sphere is created therein.

In summary, the aircraft fuselage designed according to the invention makes it possible to arrange at least two separate, sound-insulated and optically impermeable, as well as electronically shielded, passenger compartment cabin modules separated in terms of communication technology and climate technology in the production of a passenger aircraft, preferably a business jet, particularly a supersonic passenger aircraft. Preferably, the passenger cabin modules are completely decoupled / isolated from each other, for example, supplied by separate air conditioning systems, electrical systems, kitchens, sanitary facilities, etc. The communication with the cockpit is also preferably via an intercom system of the respective cabin module. The passenger cabin modules each have a corresponding interior with, for example, passenger seats, loungers, (foldable) tables, entertainment systems, own kitchen, toilet, etc. on.

A further aspect of the invention relates to an aircraft, preferably a business jet (business jet), particularly preferably a supersonic passenger aircraft, with an aircraft fuselage as described above.

Further advantages, features and details emerge from the following description in which an exemplary embodiment is described with reference to the drawings. Described and / or illustrated features form the subject of the invention, or independently of the claims, either alone or in any meaningful combination, and in particular may additionally be the subject of one or more separate applications.
