Description

CROSS REFERENCE TO RELATED APPLICATION

The present disclosure is related to the following patent application entitled: “Translating Equipment Rack System”, Ser. No. 12/985,033; filed Jan. 5, 2011, assigned to the same assignee and incorporated herein by reference.

BACKGROUND INFORMATION

1. Field:

The present disclosure relates generally to equipment and, in particular, to packaging equipment. Still more particularly, the present disclosure relates to a method and apparatus for managing equipment in different locations in an aircraft.

2. Background:

An equipment bay may be an area within an aircraft in which equipment, such as, for example, without limitation, electrical equipment, power distribution equipment, computers, and other suitable components may be installed. The equipment bay may take the form of an avionics bay or electronics equipment bay.

The equipment bay may be located, without limitation, below the flight deck, behind the flight deck, and/or adjacent to a passenger or cargo area inside of an aircraft. Equipment stored in an equipment bay may be accessible through a passenger area, a cargo area, a hatch in the flight deck area, and/or an external hatch on an aircraft.

Equipment in the electronic equipment bay may be placed in equipment racks located in the electronic equipment bay. One or more aisles may be provided between the equipment racks in the electronic equipment bay to permit maintenance personnel and other technicians to move throughout the electronic equipment bay and between the equipment racks and access the electronic equipment.

For example, without limitation, equipment racks in the equipment bay may be placed with the front of the racks facing a central aisle. The central aisle may extend between the equipment racks. This central aisle may be used by maintenance personnel to access the equipment in the equipment racks. In-flight personnel may utilize one or more hatches in the flight deck or cabin areas to gain access to the equipment in the equipment bay during a flight of the aircraft.

In addition, one or more outboard aisles may connect the central aisle to an external hatch. This hatch may provide a point of access to the equipment bay for ground crew personnel. The ground crew personnel may utilize the external hatch to enter the electronic bay and proceed down the aisles to access the equipment in the equipment racks. The ground crew may access the equipment to perform installation, removal, and/or maintenance of the equipment.

Space in the aircraft may be a valuable resource. In designing aircraft, space may be allocated to passenger areas, crew areas, cargo areas, and equipment bays. Currently used equipment bays in aircraft may use more space in the aircraft than desired. In other words, spaces, such as equipment bays, may be reduced to allow for increases in spaces, such as passenger areas and/or cargo areas.

When equipment bays are designed with less space, access to the equipment bays through aisles may be reduced. This reduction may result in more time and effort needed for equipment maintenance. Further, equipment maintenance may also take more time and effort in a presence of varying sizes and depths of the individual electronic components stored in the equipment bays.

Therefore, it would be advantageous to have a method and apparatus that takes into account one or more of the issues discussed above, as well as other possible issues.

DETAILED DESCRIPTION

Referring more particularly to the drawings, embodiments of the disclosure may be described in the context of aircraft manufacturing and service method 100 as shown in FIG. 1 and aircraft 200 as shown in FIG. 2. Turning first to FIG. 1, an illustration of an aircraft manufacturing and service method is depicted in accordance with an advantageous embodiment. During pre-production, aircraft manufacturing and service method 100 may include specification and design 102 of aircraft 200 in FIG. 2 and material procurement 104.

During production, component and subassembly manufacturing 106 and system integration 108 of aircraft 200 in FIG. 2 may take place. Thereafter, aircraft 200 in FIG. 2 may go through certification and delivery 110 in order to be placed in service 112. While in service 112 by a customer, aircraft 200 in FIG. 2 may be scheduled for routine maintenance and service 114, which may include modification, reconfiguration, refurbishment, and other maintenance or service.

Each of the processes of aircraft manufacturing and service method 100 may be performed or carried out by a system integrator, a third party, and/or an operator. In these examples, the operator may be a customer. For the purposes of this description, a system integrator may include, without limitation, any number of aircraft manufacturers and major-system subcontractors; a third party may include, without limitation, any number of venders, subcontractors, and suppliers; and an operator may be an airline, a leasing company, a military entity, a service organization, and so on.

With reference now to FIG. 2, an illustration of an aircraft is depicted in which an advantageous embodiment may be implemented. In this example, aircraft 200 may be produced by aircraft manufacturing and service method 100 in FIG. 1 and may include airframe 202 with plurality of systems 204 and interior 206. Examples of systems 204 may include one or more of propulsion system 208, electrical system 210, hydraulic system 212, environmental system 214, and translating rack system 216. Any number of other systems may be included. Although an aerospace example is shown, different advantageous embodiments may be applied to other industries, such as the automotive industry.

Apparatuses and methods embodied herein may be employed during at least one of the stages of aircraft manufacturing and service method 100 in FIG. 1. As used herein, the phrase “at least one of”, when used with a list of items, means that different combinations of one or more of the listed items may be used and only one of each item in the list may be needed. For example, “at least one of item A, item B, and item C” may include, for example, without limitation, item A, or item A and item B. This example also may include item A, item B, and item C or item B and item C.

In one illustrative example, components or subassemblies produced in component and subassembly manufacturing 106 in FIG. 1 may be fabricated or manufactured in a manner similar to components or subassemblies produced while aircraft 200 is in service 112 in FIG. 1. As yet another example, a number of apparatus embodiments, method embodiments, or a combination thereof may be utilized during production stages, such as component and subassembly manufacturing 106 and system integration 108 in FIG. 1. A number, when referring to items, means one or more items. For example, a number of apparatus embodiments may be one or more apparatus embodiments. A number of apparatus embodiments, method embodiments, or a combination thereof may be utilized while aircraft 200 is in service 112 and/or during maintenance and service 114 in FIG. 1. The use of a number of the different advantageous embodiments may substantially expedite the assembly and/or reduce the cost of aircraft 200.

The different advantageous embodiments recognize and take into account a number of different considerations. For example, the different advantageous embodiments recognize and take into account that with the space in an aircraft being a limited resource, it may be desirable to optimize the use of space for payloads that may generate revenues. For example, the different advantageous embodiments recognize and take into account that it may be desirable to increase the amount of space for passenger areas and cargo areas as compared to crew areas and equipment bays.

The different advantageous embodiments recognize and take into account that in using equipment racks with aisles in an equipment bay, the amount of space for the equipment bay may be greater than desired. The different advantageous embodiments recognize and take into account that the use of aisles in an equipment bay may increase the amount of space for the equipment bay in addition to the space used by the equipment racks. The different advantageous embodiments also recognize and take into account that in currently-used equipment bays, the design of the racks and the aisles may not be as ergonomic as desired for personnel to access the equipment in the equipment bays.

For example, the different advantageous embodiments also recognize and take into account that in some cases, an equipment bay may only be accessed through one access aisle. When access is only provided through one access aisle, all portions of an equipment rack may not be able to be accessed. Without access to all portions of the equipment rack, all storage space for components may not be able to be used. As a result, loading efficiency in the equipment bay may not be as high as desired with currently-used designs for equipment bays having one aisle for access to the equipment bay.

Further, the different advantageous embodiments recognize and take into account that providing external access to an equipment bay may require pressurized hatches and/or specialized safety systems, which may increase the weight of and/or expense for the aircraft.

Thus, the different advantageous embodiments provide an apparatus and method for providing internal access to components in an equipment bay. In one advantageous embodiment, an apparatus may comprise a rack and a translation mechanism. The rack may be configured to hold components. The rack may comprise movable rack segments that are movable independently of each other in the rack. The translation mechanism may be configured to move a portion of the movable rack segments inside a platform such that internal access to at least a portion of the components is provided inside the platform.

With reference now to FIG. 3, an illustration of a block diagram of an equipment access environment is depicted in accordance with an advantageous embodiment. In this depicted example, equipment access environment 300 may be implemented in platform 302. Platform 302 may take various forms. For example, platform 302 may be implemented using aircraft 200 in FIG. 2.

In this illustrative example, platform 302 may be subdivided into areas 304. At least a portion of areas 304 may take the form of compartments 306. Compartments 306 may be areas within areas 304 that may be partitioned off from other areas in areas 304 using structures 308. Structures 308 may be, for example, without limitation, walls, bulkheads, and/or other suitable structures.

For example, without limitation, compartments 306 may include number of equipment bays 310. In one illustrative example, equipment bay 312 within number of equipment bays 310 may be an example of one type of compartment in compartments 306.

Each of rack segments 321 may have frame 325 configured to hold various components within components 322. In other words, frame 325 for each of rack segments 321 may provide a framework to support components 322 held within rack 320. In some illustrative examples, frame 325 may be a mounting frame to which components 322 may be mounted. In other illustrative examples, frame 325 may comprise a number of shelves, trays, pins, holders, hangers, hooks, and/or other supports configured to hold components 322.

In these illustrative examples, rack segments 321 may include movable rack segments 324 that may be movable independently of each other within rack 320. Each movable rack segment of movable rack segments 324 may be an actual part of rack 320. Number of translation mechanisms 318 may be configured to move a portion of movable rack segments 324 located inside platform 302 relative to another portion of movable rack segments 324. Number of translation mechanisms 318 may be implemented using any number of devices and/or systems that may move movable rack segments 324 inside of platform 302. Number of translation mechanisms 318 may be configured to move movable rack segments 324 individually with respect to each other.

In these depicted examples, translation mechanism 326 is an example of one of number of translation mechanisms 318. Translation mechanism 326 may be configured to move portion 328 of movable rack segments 324. Translation mechanism 326 may comprise motor system 327 and number of movement devices 329. Number of movement devices 329 may be associated with rack 320 and may be configured to facilitate movement of movable rack segments 324.

A first component may be considered to be associated with a second component by being secured to the second component, bonded to the second component, welded to the second component, fastened to the second component, and/or connected to the second component in some other suitable manner. The first component also may be connected to the second component using a third component. The first component also may be considered to be associated with the second component by being formed as part of and/or an extension of the second component.

In these illustrative examples, motor system 327 may be configured to generate motion for number of movement devices 329 in a manner that moves movable rack segments 324. Motor system 327 may take various forms. For example, without limitation, motor system 327 may comprise at least one of an actuator, an electrical motor, a hydraulic motor, and other suitable types of motors. In yet another illustrative example, motor system 327 may utilize a human operator and may comprise a hand crank, a manually-powered hand hoist system, and/or another suitable device.

For example, without limitation, number of movement devices 329 may include at least one of a rail system, a number of rails, rollers, sliders, arms, wheels, tracks, a track system, hinges, pivot points, joints, and/or a re-circulating screwball jack.

As another illustrative example, translation mechanism 326 may comprise the hands of one or more human operators that may push and/or pull movable rack segments 324, a number of structures that may be manipulated by a human operator to push and/or pull movable rack segments 324, rails along which a human operator may push and/or pull movable rack segments 324, and/or some other suitable system for a human operator to move movable rack segments 324.

The movement of portion 328 of movable rack segments 324 by translation mechanism 326 inside platform 302 may be such that internal access 330 may be provided to portion 332 of components 322 inside platform 302. Portion 332 may be the portion of components 322 that is held within portion 328 of movable rack segments 324 of rack 320. In other words, operator 334 may access portion 332 of components 322 while being inside of platform 302. In this manner, internal access 330 may allow operator 334 to access portion 332 of components 322 without having to move portion 332 of components 322 or portion 328 of movable rack segments 324 outside of platform 302.

For example, without limitation, movement of portion 328 of movable rack segments 324 may move portion 328 of movable rack segments 324 from equipment bay 312 into area 336 within areas 304 in platform 302. Area 336 may be, for example, without limitation, a cargo area, a passenger area, a crew area, or some other suitable type of area within platform 302. Additionally, the movement of portion 328 of movable rack segments 324 may not move portion 328 outside of platform 302 in these illustrative examples.

In some advantageous embodiments, structure 338 within structures 308 may be associated with rack 320. For example, without limitation, structure 338 may be connected to movable rack segments 324 of rack 320. In these illustrative examples, structure 338 may comprise parts 346. Each part in parts 346 may be associated with a rack segment within movable rack segments 324 of rack 320.

Structure 338 may be used to define equipment bay 312 and/or cargo area 340 within compartments 306. For example, without limitation, structure 338 may provide a separation between components 322 held in rack 320 in equipment bay 312 and cargo 344 in cargo area 340. Further, structure 338 may be barrier structure 342 configured to prevent cargo 344 in cargo area 340 from moving into equipment bay 312. In other words, barrier structure 342 may be a barrier between cargo 344 in cargo area 340 and equipment bay 312.

In addition, in some advantageous embodiments, rack segments 321 may include fixed rack segment 348 in addition to movable rack segments 324. Fixed rack segment 348 may be configured to hold some of components 322. Fixed rack segment 348 may not be movable inside platform 302. With this type of implementation, movable rack segments 324 may move relative to fixed rack segment 348. As a result, movement of portion 328 of movable rack segments 324 is such that internal access 330 may be provided to at least portion 332 of components 322 held by at least one of fixed rack segment 348 and movable rack segments 324 inside of platform 302.

With translating rack system 314, internal access 330 may be provided to components 322 without needing additional doors in platform 302. External access 355 may be needed for some of components 322. External access 355 may be provided through number of doors 357 that may be present for other purposes other than providing external access 355.

For example, without limitation, number of doors 357 may open into cargo area 340 and may provide for movement of cargo 344 in cargo area 340 onto and off of platform 302 in addition to providing external access 355. In particular, when portion 328 of movable rack segments 324 is moved into cargo area 340, number of doors 357 may provide external access 355 to portion 332 of components 322 in cargo area 340.

In the different illustrative examples, translating rack system 314 also may include connector system 351. Connector system 351 may provide a connection to rack 320.

Further, motor 2222 may be configured to turn a number of gears (not shown) such that movable rack segment 2212 may be moved along track system 2224 along axis 2232. Motor 2226 may be configured to turn a number of gears (not shown) such that movable rack segment 2214 may be moved along track system 2228 along axis 2234.

With reference now to FIG. 23, an illustration of a flowchart of a process for accessing components is depicted in accordance with an advantageous embodiment. The process illustrated in FIG. 23 may be implemented using translating rack system 314 in equipment access environment 300 in FIG. 3.

The process may begin by identifying portion 332 of components 322 being held in rack 320 for which internal access 330 is desired (operation 2300). Rack 320 may be configured to hold components 322 and may comprise movable rack segments 324 that may be movable independently of each other in rack 320. Rack 320 may be a compartment in compartments 306 in platform 302 in equipment access environment 300.

The process may then move portion 328 of movable rack segments 324 holding portion 332 of components 322 inside platform 302 such that internal access 330 to at least portion 332 of components 322 may be provided inside platform 302 (operation 2302), with the process terminating thereafter. In operation 2302, movable rack segments 324 may be moved using translation mechanism 326.

The flowchart and block diagrams in the different depicted embodiments illustrate the architecture, functionality, and operation of some possible implementations of apparatus and methods in different advantageous embodiments. In this regard, each block in the flowchart or block diagrams may represent a module, a segment, a function, and/or a portion of an operation or step. For example, one or more of the blocks may be implemented as program code, in hardware, or a combination of the program code and hardware. When implemented in hardware, the hardware may, for example, take the form of integrated circuits that are manufactured or configured to perform one or more operations in the flowchart or block diagrams.

In some alternative implementations, the function or functions noted in the block may occur out of the order noted in the figures. For example, in some cases, two blocks shown in succession may be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. Also, other blocks may be added in addition to the illustrated blocks in a flowchart or block diagram.

Thus, the different advantageous embodiments provide an apparatus and method for providing internal access to components inside a platform. In one advantageous embodiment, an apparatus may comprise a rack and a translation mechanism. The rack may be configured to hold components. The rack may comprise movable rack segments that are movable independently of each other in the rack. The translation mechanism may be configured to move a portion of the movable rack segments inside a platform such that internal access to at least a portion of the components is provided inside the platform.

In this manner, the different advantageous embodiments may provide a system for providing internal access to components located in an equipment bay (e.g., electrical equipment) in an aircraft without requiring additional space in the equipment bay for this access. Furthermore, movement of movable rack segments holding the components from the equipment bay into a cargo area may allow an operator to access the components from inside the aircraft as compared to outside the aircraft. As a result, advantageously, a volume of space required for operation of an aircraft (e.g., typical electrical equipment) is reduced (more compact packing density) to allow for addition cargo volume.

Furthermore, the advantageous embodiments provide for dual-use of main deck, cargo back area, and surrounding areas since the area for access and to work on can be a dual usage area surrounded by test equipment. In one example, test equipment (electrical equipment) may be individually pulled into the cargo area or the main deck to gain access to the test equipment. Furthermore, the movable rack segments provide individuals or mechanics the ability to remove and/or install equipment with minimal coordination or extra personnel (e.g., elimination of the requirement of three or four persons to remove a 115 lb. box or a crane hook, for instance, running on a dedicated track to complete the removal process).

As such, principles of these advantageous embodiments reduce the number of personnel (e.g., engineers) needed on board to maintain electrical equipment. As a consequence, time for trouble shooting of electrical equipment is reduced when involving equipment removal. Furthermore, the movable rack segments provide for movement of boxes, components, or racks with minimal damage during a maintenance or trouble shooting process.

The description of the different advantageous embodiments has been presented for purposes of illustration and description and is not intended to be exhaustive or limited to the embodiments in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Further, different advantageous embodiments may provide different advantages as compared to other advantageous embodiments. The embodiment or embodiments selected are chosen and described in order to best explain the principles of the embodiments, the practical application, and to enable others of ordinary skill in the art to understand the disclosure for various embodiments with various modifications as are suited to the particular use contemplated.
