- the invention relates to the configuration of aircraft.
- the invention relates to an aircraft configurator for calculating locations of consumers and routes along which consumers are to connect to appropriate suppliers, a method of calculating locations of consumers in an aircraft and routes along which consumers are to connect to appropriate suppliers , a program element and a computer readable medium.
- modified airfoils and hull shapes can be used to improve the aircraft's resistance and buoyancy characteristics. For certain applications, it may be make sense to provide so-called. Winglets at the ends of the wings, which can improve the aerodynamic properties of the aircraft.
- a first aspect of the invention relates to an aircraft configurator for
- Aircraft configurator is, for example, a computer-aided system having a data memory on which comprehensive structural data of the aircraft and the components to be installed therein are stored. In particular, information about the geometry of the aircraft and about the consumers and suppliers to be installed therein or all available for installation are stored in the data memory.
- An input unit is provided, which is designed for entering the installation locations and the type of consumers to be installed. In addition, one is
- Arithmetic unit which is designed to identify a supplier to which a corresponding consumer is to be connected, as well as for calculating a number of alternative routes along which the consumer can be connected to the supplier. After the arithmetic unit has now calculated alternative cable or cable routes, along which the cables or cables can run to connect the consumer to its associated provider, the arithmetic unit can identify that of the calculated routes, in which a so-called.
- Key performance indicator or a (mathematical) function eg a sum) of several, for example differently weighted key performance indicators of the aircraft is optimal eg with regard to the length of the aircraft or its weight.
- the one key performance indicator or the function (more precisely, the value of the function) from a plurality of key performance indicators is as small as possible.
- the aircraft configurator is able to calculate and output the optimal cable route for the intended use of the aircraft.
- the key performance indicator is, for example, the weight of the aircraft, the distance of the center of gravity of the aircraft from a desired center of gravity position, or the installation time required to install the consumer and establish the connection between the consumer and the utility.
- the key performance indicator to be optimized can be the installation time.
- the selected cable route ensures that, on the one hand, the weight of the aircraft is as low as possible, but on the other hand, that a certain maximum construction time is not exceeded, and, moreover, that the distance of the center of gravity from the optimum center of gravity position does not exceed a certain threshold exceeds.
- system may be designed to allow the use of standard cables, as this can reduce installation and manufacturing costs.
- the arithmetic unit changes from itself the installation location of a user to be installed by the user in order to further optimize (for example, reduce) the key performance indicator or the function or the function of the differently weighted key performance indicators.
- an input unit for inputting the key performance indicator can be provided.
- the arithmetic unit is designed for the identification of consumers whose installation locations are not to be changed.
- the user can prevent the arithmetic unit of itself from changing the installation locations of certain consumers in order to optimize the key performance indicator or the sum of various key performance indicators, that is to say to reduce them, for example.
- the consumers are, for example, aircraft toilets, sinks, kitchen appliances, ventilations, lights, loudspeakers and / or display devices, seat supplies, Communication systems such as on-board telephones, flight personal displays, service switches.
- the corresponding suppliers are, for example, water tanks, fuel cells, fuel tanks, air sources or air conditioning components or, in general, power or data sources.
- the arithmetic unit is designed to create an installation plan for the consumer and further comprises an output unit for outputting the installation plan to a user.
- This installation plan may refer to the provision of information about the installation locations of consumers and utilities as well as the corresponding, too
- the installation plan may contain additional information, such as information about the type and design of the
- the arithmetic unit may be programmed to exchange a user-selected consumer with another consumer if this results in optimizing the corresponding key performance parameter or the sum of the key performance parameters.
- the computing unit can also be designed to change the design of a consumer, for example the position of the connection interfaces, via which the consumer is connected to the line or the cable.
- the installation plan includes all cabin installations as well as the structural components of the aircraft, which in part have an effect on the cable route to be carried out, but at least takes into account.
- the arithmetic unit may be programmed not only to calculate alternative routes and possibly to change the installation location of one or more consumers or suppliers, but also to change the installation location and / or design of another component or structural element of the aircraft to achieve the desired goal, namely the optimization of a key performance indicator or a function of key performance indicators.
- Another aspect of the invention relates to a method for calculating locations of consumers in an aircraft and routes along which consumers are to connect to appropriate suppliers. This initially stores information about the geometry of the aircraft and about installable consumers and utilities. Furthermore, installation locations and type of consumers to be installed are entered and a utility is identified, to which the corresponding consumer is to be connected.
- Performance indicator or a function of several differently weighted key performance indicators of the aircraft is optimized or as low as possible.
- a further aspect of the invention relates to a program element which, when executed on an arithmetic unit of an aircraft configurator, the
- a further aspect of the invention relates to a computer-readable medium on which the program element described above is stored.

- Fig. 5 shows frames of an aircraft.
- Fig. 6 shows a cross section of the fuselage of an aircraft, divided into different areas.
- Fig. 1 shows an aircraft configurator according to an embodiment of the invention.
- the Aircraft Configurator is used to calculate locations of electrical or other loads in an aircraft, and routes along which consumers are to be connected to appropriate providers in the aircraft.
- the aircraft configurator has a computing unit 101 which is connected to the
- the arithmetic unit requires comprehensive data, which are stored in the data memory 103, and which in particular include information about the geometry of the aircraft and about installable consumers and suppliers.
- the arithmetic unit 101 is connected to an input unit 102, which is designed for inputting the installation locations and the type of consumers to be installed.
- an output unit 104 for example in the form of a printer or a display, is provided, via which the installation and connection diagram generated by the arithmetic unit 101 can be output.
- the output can be in the form of a PD (Principle Diagram) of a FD (Functional Diagram) or a WD (Wire Diagram).
- the arithmetic unit can, for example, consult a three-dimensional grid which images the geometry of the aircraft and its installations. Starting from this three-dimensional grid, the arithmetic unit can now have a specific consumer Position at a specific point and then calculate possible cable and / or cable routes from the consumer to the corresponding supplier.
- This process can then be carried out for all consumers and suppliers. It can be provided that the user determines the position of one, several or all consumers themselves.
- the computing unit may be programmed to change the position of one or more or all consumers (unless the user has prohibited this for one or more consumers), followed by a re-calculation of the corresponding cable routes.
- the arithmetic unit can compare whether the new positions and cable routes are "cheaper" than the previous ones, if so, for example, certain positions can be defined as fixed and other positions or
- Cable routes can be varied again to get even better results. This iterative process may be performed until a selected Key Performance Indicator or function of multiple Key Performance Indicators (for example, this may be a sum of different Key Performance Indicators that are weighted equally or differently) to an acceptable, predetermined one Size was optimized.
- Both the consumers and suppliers to be installed in the aircraft as well as the other installations to be installed therein as well as the cables and lines that can be used can be defined by means of description logic.
- An example of this is shown in FIG. 2, in which a position indicator r2, c2 is to be seen, which is described with logical statements in the form of description logic.
- the position indicator 201 may be located to the right of the installation (see arrow 203), to the left of an installation (see arrow 202), over the installation (see arrow 205), or under the installation (see arrow 204).
- a fundamental consideration is that the aircraft or at least a certain area of the aircraft, for example the fuselage or the passenger cabin, is subdivided into abstract areas of space.
- These spatial regions can be predetermined, for example, by the former regions in the x-direction (see FIG. 5). These different regions can also be split further in the yz plane (see FIG. 6, which shows a cross section of the fuselage).
- the x-axis in this case runs in the direction of flight, ie along the longitudinal axis of the
- the z-axis is the vertical axis and the y-axis is the transverse axis.
- Aircraft configuration considering one or more key
- Performance indicators eg total weight, installation time,
- the arithmetic unit outputs, for example, an installation plan for the consumers, which indicates the position and the type of consumers as well as the corresponding line and / or cable routes.
- the use of description logic describes the functional, possible links between consumers, cables and lines, utilities and other components of the aircraft.
- Fig. 3 shows a possible result of the method described above.
- Places 301 and 302 indicate the positions of a consumer and a utility, which should be connected to each other.
- the direct route leads diagonally through the aircraft cabin (see 303).
- Alternative routes are designated by lines 304, 305, 306.
- Route 306 takes into account geometric factors such as the shape of the fuselage, the shape and position of structural components such as frames and stringers, and brackets attached thereto.
- the aircraft configurator compares the various alternative line and cable routes 303-306 and identifies the route for which a selected key performance indicator or, for example, a sum of weighted selected key performance indicators is most optimized (e.g., lowest). This route is then chosen for the aircraft's construction.
- FIG. 4 shows a flow chart of a method according to an embodiment of the invention.
- step 401 retrieving information about the geometry of the aircraft and about installable consumers and suppliers from a computing unit from a database.
- the arithmetic unit receives installation locations and type of consumers to be installed from a user, and in step 403, the arithmetic unit identifies a particular utility to which a corresponding consumer is to be connected.
- step 404 various alternative routes along which the consumer is connectable to the provider are calculated and, in step 405, that of the calculated routes is identified where a key performance indicator or a sum of several key performance indicators of the aircraft is minimal.
- step 406 a corresponding finished installation plan is output.
