Abstract

The floor (3), of an aircraft cargo hold, has support beams bonded to the fuselage and which also carry functional units e.g. water tanks (58), waste tanks, electronic units (56) and the like. The units are mounted on pallets (70), which are locked rigidly to the floor by fasteners (71). Connections (61) link the units to connection lines (26,27) through the floor structure.

Description

The The invention relates to an aircraft according to the preamble of the claim 1 and a method for manufacturing an aircraft.

Aircrafts become common equipped with a cargo hold, the cargo compartment floor via supporting elements, especially floorbeams, on the body or is supported on a skin of the aircraft. In the cargo hold will not just charge, e.g. baggage the passengers, stowed away, it also become functional assemblies, e.g. Water tanks, waste water tanks, EE racks or the like. Electronic assemblies There firmly attached. The installation of these functional modules as well their exchange is complicated.

Of the Invention is based on the object, an aircraft and a method for the manufacture of an aircraft to the effect that functional assemblies be mounted and dismounted in a simplified manner.

These Task is solved by that in one Aircraft comprising a cargo hold with a cargo hold floor, Support elements, especially floorbeams for supporting of the cargo hold floor and to connecting with a body or a skin of the aircraft and functional assemblies, in particular Water tanks, waste water tanks, EE racks or the like. Electronic assemblies, the functional assemblies, pallets or the like. Support structures include to the To transport functional assemblies in the cargo hold, wherein the Pallet fasteners for fixed connection with the Have cargo space floor.

One The essential point of the invention is thus that the functional assemblies, usually as fixed components of an aircraft are now considered to be transportable units, which can be transported into and out of the cargo compartment as required are. This completely new way of looking at the functional assemblies has not only in construction a big plane Benefits, it leads rather, also in the maintenance / entertainment of an aircraft to great relief. In particular, you can namely the functional modules namely outside the Plane for to be alone, changed or be repaired, so in an environment that is a much more comfortable Works possible as the narrow hold of an aircraft. In addition, you can the functional assemblies use other working techniques, than within the (cramped) hold, ie at the installation site the function modules can normally be used.

Preferably have the pallets or the functional assemblies and / or the cargo compartment floor connecting devices on to connecting lines or the like. Functioning of the Functional assemblies to corresponding connecting lines of the aircraft to join. In the case of a water tank as a functional assembly are such connection devices Sleeves and pieces of hose over which the necessary connections to the water / sewage pipes of the Aircraft are created. In the case of EE racks, these are more complicated Structures of the aircraft wiring.

Of the Cargo space is preferably equipped with guidance facilities to lead of the functional modules when being transported inside the Cargo space. Such leadership facilities can which also for Cargo pallets used guides be on the cargo hold floor. But it can also separate management facilities be provided to the functional assemblies at least in the sections, in which they are final be attached, to lead to special places.

The guide devices can also guide rails on sidewalls and / or on the ceiling of the cargo hold, in particular then makes sense if the function modules over the full height and / or Width of the hold enough. This is especially the case if the pallets comprise at least sections of partitions, which are mounted on them or can be mounted on them. such partitions as part of the functional assemblies, is also an essential thought for is new on its own. Then, if partitions (or sections thereof) mounted on pallets, you can move them very easily, to create in the cargo compartments for special use or to enlarge existing compartments or to downsize.

you can now mount functional assemblies on sections (or whole) partitions, such as this is in principle also already common in the assembly of some functional modules. In the present case, however, then form the partitions together with the function modules on their pallets separate components whose assembly outside the plane is relieved and then in a simple manner the cargo space can be moved in and fixed there. The Have partitions preferably here sealing means for sealing against the Hold on so that one filling of the hold with extinguishing gas in the case of a fire is readily possible.

In one embodiment of the invention, the cargo hold floor comprises floor elements, which with the support elements to prefabricated Bodenmo are connected. In this way, an assembly of the cargo compartment floor together with the associated support elements outside of the aircraft is possible, which also brings the above-mentioned advantages. In this case, sections of cable ducts, hydraulic lines, water lines, power lines or the like are preferably provided in the floor modules such that they form overall line systems with similar line installations of adjacent floor modules when the floor modules are mounted in the aircraft. In this way, the floor modules simultaneously also form portions of the ductwork, with branches being provided for connection to predetermined locations of the floor panels and / or the functional units, if desired. This greatly facilitates the construction of piping systems within the aircraft. Overall, therefore, the floor modules in this embodiment of the invention should not only include the complete wiring and drainage, etc., for the organs of the freight loading system, but should preferably also have the complete "ducting" for the entire aircraft, eg the air conditioning or other wiring, which in normally only pass through this area of the aircraft. This achieves a considerably more efficient way of working during the construction of the entire aircraft.

Preferably the mounting elements on the floor elements are mechanically strong Connecting adjacent floor elements during or after assembly provided in the aircraft. It is possible in this way, the floor elements too a solid, stable and stiff surface to connect, which the entire plane increased Gives stability and significantly strengthened the cargo hold floor.

The Floor elements, like the partitions, preferably include sealing means for sealing a space above the floor elements with respect to one Space below the floor elements. This sealing happens to one opposite Liquids, e.g. Water entering the cargo hold with loaded containers becomes, to the other opposite Gases, as for extinguishing used by fire, causing the cargo hold to suffocate can be filled by fire with an inert gas. These sealing devices are particularly simple (e.g., in the form of a sprayed layer) to install, since the floor modules are mounted outside the hold and therefore accessible from below are.

Preferably are sealing fasteners for tight connection of the floor elements with provided adjacent floor elements and / or the skin of the aircraft. These sealing elements are in particular constructed so that after the Installation of a floor module, the floor element of this module with the adjacent floor element as well as with the cargo compartment seals and a separate, subsequent Seal can be omitted.

Preferably are drainage facilities for discharging of liquid from the cargo hold and for passing the liquid in appropriate drainage facilities provided adjacent floor modules, so that a separate attachment Of lines for draining the water is not necessary.

The Floor modules continue to be insulated with isolation equipment a lower hull half shell provided. This one has the insulation not retrospectively Instead, you can get them outside of the aircraft to the Mount modules. These isolation devices can either be placed under the floor elements, especially outside the aircraft is very easy to do, or (if necessary also in addition) in the area of the supporting elements, be placed close to the skin, if desired. It is thus work in the narrow, under the cargo compartment floor area of the aircraft unnecessary.

The Floor modules also include bulkheads or the like. Partitions or but fasteners for attaching partitions as they in certain hold sections (as discussed above) later to be assembled. The partitions can So either already attached to the floor modules or on pallets fastened and then pushed into the cargo hold. The partitions exist preferably at least partially made of ballistically resistant material, so that one higher Security guaranteed is. The floor modules can furthermore wall coverings and / or ceiling coverings or the like. Include cladding or mounting means therefor, for lining the cargo hold. This also allows a simplified Construction of an airplane.

The above object is procedurally in an aircraft comprising a cargo compartment with a cargo hold floor, supporting elements, in particular Floorbeams for supporting the cargo compartment floor and for connecting to a body or skin of the aircraft as well as functional assemblies, in particular water tanks, sewage tanks, EE racks or the like. Electronic assemblies solved by the fact that the functional modules are mounted outside of the aircraft on pallets or the like. Support structures, the assembled function modules are invited into the aircraft and driven on the cargo hold floor to a destination in the cargo hold and mounted Functional assemblies are attached to the destination at the cargo hold floor. The advantages already explained above are evident in this method.

Preferably Be on the pallets or on the functional assemblies outside the aircraft mounted at least sections of partitions, so that the installation work continue to be relieved.
