The present invention relates to a rest module, the use of a rest module in an aircraft and an aircraft comprising a rest module.
Today's commercial aircraft cabins are designed to accommodate crew members in special rooms. More precisely such rooms may be designed as so-called crew rest compartments or rest modules which belong, according to statutory provisions, to the mandatory equipment of airplanes for long distance flights. Therefore, according to international standards for long distance flights, for flights with a time duration of 8 to 14 hours there may be a need for one arrangement to lay down and for flights with more than 14 hours two arrangements to lay down are needed. This is caused by the requirement, that by exceeding a certain time duration of the flight there must be two entire flight crews on board of the airplane.
It shall be noted, that the term crew rest compartment and crew, always may consider the flight crew of an aircraft as well as the cabin crew of an aircraft. This of course does not exclude, that other persons may use the inventive rest module.
During the recent years the security demands in airplanes have been increased rapidly, which also includes the securing separation of the cockpit area from the passenger area. From a constructing point of view it might therefore be desirable that the flight crew has a direct spatial access to such a flight crew rest compartment (FCRC) from the cockpit area, without the need to cross the passenger area. Beyond this, security requirements like for example being fireproof or bullet-proof may arise or be important for the construction of such crew rest compartments.
Today's commercial flight crew rest compartments are realized in the ceiling area, the so-called crown area of the airplane with two adjacent sleeping arrangements. In most of these realizations the flight crew has to pass a certain way in order to reach the flight crew rest compartment. On the one hand the habitation area in the inner side of these compartments is commonly very narrow and on the other hand the following passenger area for example the so-called first class area is commonly very commodious and spatially wide. Such a first class area may eventually not offer the full technical height over the whole area. That may further mean, that a CRC (crew rest compartment) can optically influence the appearance of the cabin design.
Further on known solutions of crew rest compartments or flight crew rest compartments do not provide a spatial division or separation between different cabins for single crew members and are therefore not optimally designed in the sense of room and space configuration. The privacy may therefore not be provided during a rest session of an user.
In the past any solutions for CRCs or FCRCs provided two sleeping arrangements. Because the crew is joined by a second pilot in only 70 to 80% of the flights, the second bed and all its appropriate components may be transported unnecessarily. The second bed may require a lot of storage or loading space which volume may be urgently needed in airplanes. Further on the additional fraction of the weight of the airplane has just now to be avoided during times, when wide body airplanes become more important.
In difference to the solutions for the flight crew the compartments of the cabin crew are for example arranged at the rear end of the airplane. With this configuration of the two compartments there normally arises the need for two different ladders or aids in ascending.
In recent times where the reduction of the emission of exhausts becomes more and more important additional mass, volume and components especially in crew rest compartments should be avoided.
It is an object of the invention to provide an improved crew rest in an aircraft.
The object may be solved by a rest module, by a use of a rest module in aircraft and by an aircraft which comprises a rest module according to the independent claims.
According to an exemplary embodiment of the invention, a rest module for accommodating at least one crew member of an aircraft is provided. The rest module comprises a first partial module, wherein the first partial module comprises a first section and a second section. Further on the first section and the second section are spatially divided and the first section comprises a first, a second and a third opening. These openings are different from each other. The first opening is adapted for providing an access from an above-located area of the aircraft, wherein the second opening is adapted for providing an access from the first section to a second partial module. The third opening is adapted for providing a separate access from the first section to the second section. Furthermore the first partial module is permanently fixed in an electronic bay before a cargo wall of the aircraft, and the second partial module is located behind the cargo wall.
In principle the electronic bay (which is also called e-bay) provides for the electronic power of the aircraft and the electronical controlling systems, the so called aircraft intelligence. Also segregated power supplies (PEPDC and SEPDC) and different equipment like several batteries, relay box, sensing and measurement units like e.g. horizontality measurement units are installed in the e-bay. Also temperature, speed and pressure may be measured. Also harnesses and ventilation pipes may be present in the e-bay.
According to security requirements the electronic bay of an aircraft must be supplied with two identical avionic bays. Each of these two segregated systems may comprise an electrical equipment box with all calculators and IT stuff necessary for the aircraft. In case of a damaged first avionics bay the second avionics bay may provide the aircraft with the necessary functions. Further security requirements demand a minimum distance between these two identical electronical and IT systems.
According to this exemplary embodiment of the invention the space between this first and second avionics bay is used in a space saving way. Furthermore the housing of the rest modules comprising or being the outer walls of the rest module may be constructed in such a way, that is may be used as protection element between the first and second avionics bays. In case of e.g. a fire or an explosion in the required distance area between the two avionics bay, the presence of the rest module may securely protect the electronical components. Therefore the rest module may comprise e.g. fireproof walls, bullet proof walls or explosion resistant walls or any combination of these.
Thus by means of installing the first partial module into the nearly unused area between the two avionic bays in the e-bay, the use of expensive revenue space for accommodating the crew members may be avoided. Furthermore the security of the whole aircraft is increased, as the aircraft intelligence and electronical power centre of the aircraft is protected in an enhanced way.
The terms “first and second sections” of the exemplary embodiments of the present invention may also be divisions, areas, or spatial rooms that fulfil the requirement, that the first and second section are spatially divided. This spatial division means, that potential users of the first partial module that are situated in the two different sections do not get any sonic, visual or mechanical hint of the presence of the other user in the first partial module. This might be arranged due to a separation wall that is soundproof, optically not transparent and may also separate the two divisions from smells or exhalations.
This spatial division of the first and second section of the first partial module causes the effect or advantage, that an incoming first person does not disturb a potential second person, that is simultaneously using the second division of the first partial module. That means that the spatial division is arranged and has to be arranged in such a way, that a first user in the second section of the first partial module can follow all his wanted activities without being disturbed in any way by a person entering the first section of the first partial module.
The three inventive openings of the first section are different from each other and may also be seen as apertures, holes, ports, doors and all mechanical arrangements that allow people to have access through these inventive openings.
The openings may thereby be arranged as common doors, that provide access from the first section of the first partial module to the second section, to a second partial module and to an above-located area of the aircraft. The first opening, which connects the level of the module with the above-located level of the aircraft may be realized for example as a sliding door, a hatch, an emergency exit hatch, as a flapping mechanism or for example as a mechanical port realizing an entry for the module users.
The above-located area of the aircraft may therefore be any section of the upper deck along the longitudinal axis. This may be the cockpit, an area with the crew rest compartment, the passenger area, or especially the crown area of the airplane.
As it is later on shown (for example in
The third opening which can for example be realized as a door in the spatially dividing wall between the first and the second section is providing a separate access from the first section to the second section. This causes the advantage, of using only one staircase while ascending or descending to or from an above-located area of the aircraft for all users, but not causing any influence of the usage of all the second sections of the inventive module.
As this exemplary embodiment of the invention may be capable to be docked on a second partial module or capable for docking on at a second partial module the invention realizes a connection of two crew rest compartments or flight crew rest compartments on one level. The first partial module is thereby fixed entirely on this level wherein the second partial module or more additional partial modules may be added as dock-on modules. This exemplary aspect of the invention offers an increase of flexibility of such compartments and may reduce the required space of the module on the cabin deck or so-called upper deck.
According to a further exemplary embodiment of the invention the first and the second partial modules are adapted for being mounted on a cargo level of the aircraft.
The two partial modules (or more additional partial modules) may be mounted and fixed at the ground of the cargo level and therefore be treated and handled like typical cargo containers. This causes advantages in the required space for the rest module on the main deck, the advantage of a flexible handling of the partial modules on the cargo level of the aircraft and further on the advantage, that the shape and the physical form of the partial modules may not fulfil the requirements that exist for crew rest compartments on the main deck. This may lead to constructing advantages for the building engineers, which do not have to plan the rest module with the limitations or requirements of optical, mechanical and designing aspects of the crew rest compartment.
This may also contain the possibility to easily dock-on a second partial module at the first partial module that is fixed on the cargo level during all the time. This docking-on process may be going on much faster, easier and with less energy and working effort as it would have been if this configuration would have been placed on the main deck. This docking-on process might be supported by special cargo transport belts with which the mobile module can be situated at its appropriate position.
According to a further exemplary embodiment of the invention, the first partial module is adapted for docking-on the second partial module.
In difference to other exemplary embodiments where the second partial module may be located in a distinct distance to the first partial module it may also be possible to link the first and the second partial module mechanically together. This might be realized in a first way, where the first partial module and the second partial module might be placed adjacent to each other by the fixation of each module is done separately in each module for example by fixing each module to the ground of the level for example the cargo level. But also a second possibility is given herewith wherein both partial modules offer a common element which mounts the two modules physically and mechanically together. This dock-on possibility creates a pool of advantages in a sense of flexibility, required space, avoiding additional weight of the airplane and therefore avoiding additional exhausts of the airplane and offering more needed space for especially additional cargo.
This docking on variation of the invention may also be possible for additional partial modules.
According to a further exemplary embodiment of the invention, the rest module further comprises a connecting element, wherein the connecting element is adapted for docking-on the second partial module at the first partial module or at the cargo wall.
This connecting element may offer additional stability for the first and the second partial modules while they are simultaneously anchored or fixed on their ground level. But also a sole fixation of the two modules against each other is possible through this connecting element. Each mechanical apparatus, device or mechanism that provides a fixing connection between the first and the second module may fulfil the requirements for the here defined connecting element. For example may a screwing or riveting fixation be realized.
In other words it is possible, that the first partial module is docked on to the cargo wall with a first connecting element and the second partial module is docked on to the cargo wall with a second connecting element. Thus, the two modules may be separated from each other by the cargo wall. This exemplary embodiment of the invention also comprises, that the two modules may laterally be shifted against each other. This may be used for special space saving configurations if the first and the second partial module.
According to a further exemplary embodiment of the invention the above-located area of the aircraft is the cockpit of the aircraft.
This means, that the rest module of the present invention is directly or nearly directly located underneath the cockpit area on the cargo level. This might for example be seen in the
This also means that the inventive rest module would then be called a flight crew rest compartment as it offers the possibility of the flight crew to directly enter the inventive module from the cockpit area if a second door (as privacy door) between Lavatory and Galley is installed. This offers the advantages that the paths and times a flight crew member needs in average to get to his rest module is therefore minimized and optimized. This solution offers also the possibility to shape the whole unity of cockpit and appropriate rest module for the flight crew has one entire and spatially completed, mechanical unit. In times of higher terroristical potentials the security requirements of the area where the flight crew spends their hole time during the flight must securely be separated from that part of the airplane that can be entered by unauthorized persons.
This exemplary embodiment also corresponds to the need or demand of a flight crew rest compartment, that normally it has to offer one sleeping arrangement or resting arrangement but can be easily upgraded with a module for the flight crew. Then two sleeping arrangements may be offered in the case of having two entire flight crews on board.
Further on this exemplary embodiment of the invention realizes the possibility for the flight crew to directly enter the rest module without having the need to pass the eventually unsafe area of the passengers or the cabin crew. Therefore, the inventive rest module and the accompanied cockpit deliver all services, facilities and devices that are needed for the flight crew during the whole flight time. This means in a sense of independency that the flight crew may be totally autarkic or self-sufficient in its cockpit area and connected rest module.
According to a further exemplary embodiment of the invention, each of the partial modules comprises a sleeping accommodation.
This sleeping accommodation which is also expressed by the words sleeping arrangement, resting possibility or bed is needed to fulfil the legal requirements of the sleeping equipment for a cockpit crew depending on its flight duration. Sleeping accommodation may be realized through various different embodiments wherein a bed, a pallet, a foldable plate or a couch are possible embodiments.
According to a further exemplary embodiment of the invention, the first section comprises an aid in ascending.
As the inventive rest module offers a first opening which provides access from an above located area of the aircraft, this area can be reached by the aid in ascending. This expression of course does not exclude the possibility that this aid might also be used for descending down to or into the module. Depending on the height or the level where the module is used in the airplane the aid might be leading into the crown area of the airplane or more commonly onto the main deck of the airplane especially into the cockpit.
According to a further exemplary embodiment of the invention, the first module comprises an integrated staircase.
This integrated staircase may also be realized as a so-called vestibule or also as a stairway or a well. Also simple stairs which allow a user to ascend or descend out of the module or into the module are possible solutions of the aid in descending which is integrated in the integrated staircase. In contrary to common solutions this exemplary embodiment offers a direct but separate access to both compartments.
According to a further exemplary embodiment of the invention, the rest module comprises at least one additional partial module, wherein the second opening is further adapted for providing an access from the first section to the at least one additional partial module.
As later on shown for example in
As all of these additional partial modules can be arranged as dock-on modules it is also possible to form one mechanical unity out of the first partial module and the other additional partial modules. This mechanical unity might then be placed on the cargo level of the aircraft and therefore decrease the used space and volume for accommodating the crew on the main deck.
According to a further exemplary embodiment of the invention, at least one of the partial modules is shaped as a conventional cargo container.
This form solution of at least one of the partial modules may create a few advantages concerning the requirements of the physical shape, the material and the handling of the rest modules. This means for example that the partial module does not have to be optically attractive, as it is not presented to the passengers. Further on this may lead to a better integration of the module on the cargo level, as the cargo container shaped modules may fit physically better in their cargo surrounding. This may further on create more storage space or freight hold on the cargo level.
According to a further exemplary embodiment of the invention the first partial module is part of a flight crew security area.
As the first partial module is located in the electronic bay which is located close to nose of the aircraft the rest module is close to the cockpit. Due to higher security standards for the flight crew a special flight crew security region may be compulsory within the aircraft. The installation of the first partial module into the area between the cargo wall and the region of the nose landing gear allows technically to insert the first partial module in such a special flight crew security region. It might thus be possible to build a complete mechanical unit by the shown first partial module and the above located cockpit with maybe further elements like e.g. lavatories. Thus a short and safe way for the flight crew into the first partial module in the electronic bay can be realized. Thereby a flight crew member does not need to leave this spatially divided and secure flight crew area on his way to the electronic bay.
According to a further exemplary embodiment of the invention, the use of a rest module according to one of the exemplary embodiments in an aircraft is provided.
According to a further exemplary embodiment, an aircraft is provided which comprises a rest module according to one of the exemplary embodiments.
The exemplary embodiments of the module are also valid for the use of a module in an aircraft as well as for an aircraft comprising such a module.
In the following, exemplary embodiments of the present invention will be specified for further explanation and for better understanding with reference to the attached drawings:
Similar or relating components in the several figures are provided with the same reference numerals. The view in the figure is schematic and not fully scaled.
As clearly shown in
The first partial module (101) may further be permanently fixed in the electronic bay before the cargo wall and the second partial module (102) may be located behind the cargo wall.
Furthermore it may be seen, that the rest module (100) may serve as mechanical bearer between the floor of the electronic bay and the above located floor of the main deck, which increases the mechanical stability of that region of the aircraft. Thus the rest module may be integrated in the e-bay as a structural element of that aircraft region, wherein the rest module at least intercepts a few percents of the loads, being present in that region of the aircraft region. In other words the rest module may be adapted to intercept not circumstantial loads within the e-bay.
As it can be seen in all three figures
As one can see all three openings 105, 106 and 107 are different from each other, and are further on working independently from the state of each other opening.
As one can clearly see in
As a further characteristic feature of this exemplary embodiment one can clearly see that each module exhibits or comprises a division into a first section 103 and a second section 104. This is done and realized by a separating wall 116 that is shown in each of the three modules. This creates a public area in each partial module to provide different access possibilities for a locomotion from one partial module to another or from one partial module to other possible areas of that aircraft level. This access to possible areas of that aircraft level 125 and the direct but separate access to the additional partial modules 102 and 103 which access 122 is shown and indicated by arrows. Further on the direct and separate access to each second section which is the private and intimacy section of each module is indicated by the arrows 123. The cargo wall (not shown) would span along the first partial module (101) and the second partial module (102).
An important aspect of this embodiment of the invention is, that the first partial module (101) is permanently fixed in the electronic bay (129), which means before the cargo wall (130) and thus not in the cargo compartment or cargo area (131). This installation has the economically highly relevant consequence that no revenue space has to be used for accommodating crew members, as no cargo space is required in such a base installation without a second partial module (102). As the electronic bay is located close to the nose of the aircraft a second advantage of this installation is generated. Due to higher security standards for the flight crew a special flight crew security region is provided within the aircraft. The installation of the first partial module allows technically to insert the first partial module in such a special flight crew security region. It might thus be possible to build a complete mechanical unit by the shown first partial module and the above located cockpit and maybe further accommodation elements like e.g. lavatories. Thus a short and safe way for the flight crew into the first partial module in the electronic bay can be realized within this security area. The flight crew area is thus adapted in such a way, that a flight crew member does not need to leave this spatially divided and secure flight crew area on his way to the electronic bay (129). Direct and secure access from the cockpit to the first partial module is provided.
In case of a demand for more crew rest space, a second partial module 102 is docked on at the first partial module 101. This second partial module 102 and further partial modules are located behind the cargo wall and thus situated in the cargo area. A docking possibility is to use a cargo door in the cargo wall (130). In addition to those advantages of such a combined crew rest installation in the electronic bay and optionally in the cargo area, still only one common aid in ascending or staircase (see (109) in
Furthermore, the second partial module 102 may be docked on to the cargo wall 130 in such a way, that an access from the electronic bay 129 through the cargo wall directly into the second partial module is provided. Therefore an opening of the second partial module may cover the surface of the opening of a door in the cargo wall. As can bee seen in
Further on
A double security boarder is generated against adversely influences and intrusions, like fire, explosions, gun shots or chemical attacks by means of the two walls 137 and 144. In combination with
As the cockpit wall can be locked, also access for maintenance purposes may be provided though the entrance 127 to the cargo level, without having to make the safe cockpit area unsecure. Thus an additional access for maintenance people may be avoided which may reduce the weight of the aircraft.
As one can clearly see in
The first avionic bay 141, which may comprise several elements like e.g. racks or server is shown on the left hand side in an secure and required distance from the second avionic bay 143. The first partial module 101 of the rest module 100 is installed in the e-bay 129 before the cargo wall 130 between the first and second avionic bays. This wall protects the e-bay and the first partial module in for example the case of a rapidly compression.
Thus a beforehand unused space, that may be relatively cheap compared to revenue space in the cargo area is used for accommodating crew members. In other words the two different functionalities cabin and electronics are advantageously combined and the e-bay is securely separated into two partial e-bays by the first partial module. Additionally the walls and the mechanical structure of the first partial module may be arranged in such a way, that the module serves as a protection for both the first and second avionic bays. The rest module may further have a maintenance trap or flap 146 of the first partial module to provide for access to the first avionics bay 142.
A corridor for reaching the second partial module 139 is further shown. This corridor in the e-bay is for the access to the second partial module 102, for the access to the avionic bay 143 and equipment. Covers may be integrated to protect the electronical components of the avionic bay and to protect the crew members. As the landing gear area obeys a limited height it may not be convenient for these accommodating purposes.
It shall be noted, that the term “rest” used in the previous and the following content of this application comprises the meaning of both to remain, to stay, to work, to sleep and to relax. All these activities are possible in the inventive compartment and all apparatuses needed for them may be installed inside the modules.
It should be noted, that the term “comprising” does not exclude other elements or steps and the terms “a” or “an” does not exclude a plurality. Further on elements described in association with different embodiments may be combined.
It should also be noted that reference signs in the claims shall not be construed as limiting the scope of the claims.
