Description

Technical Field

[0001] The present disclosure relates to aircraft manufacturing processes. More specifically, the disclosed embodiments relate to systems and methods for positioning and aligning aircraft parts relative to an aircraft or aircraft structural features. Background Art

[0002] The manufacture and service of large commercial aircraft often presents special challenges. In particular, the power plants of such aircraft are not only large and mechanically complex, but their assembly may require high precision to accommodate the tight tolerances that are often required.

[0003] This is particularly true for the turbofan powerplants used in many commercial aircraft. An aircraft's turbofan powerplant is typically housed in a nacelle 2 that is attached to a wing 4 of an aircraft 6 via an engine strut (or pylon) 8. Some of the components of the engine nacelle are located in the Figure 1 1 and may include, among other components, an inlet cowl 10, a fan cowl 12, a thrust reverser 13, an exhaust nozzle assembly 16, and of course the turbofan engine assembly 18 itself.

[0004] like Figure 2 As shown, the installation process of many large nacelle components may require a crane and several skilled technicians to install the thrust reverser 13 on the pylon 8 of the aircraft 6. The thrust reverser 13 may be fixed to and hoisted by the crane sling 20. When suspended from the crane, a person 22 present on the work surface 24 can guide the thrust reverser 13 into place by hand, while an additional technician 26 may be required to perch on top of the engine strut 8 to guide the thrust reverser 13 into the proper position for installation. This may require the technician 26 to lean outward above the work surface 24 of the factory floor, which may be a dozen feet or more below, in order to guide the nacelle components into the proper position by eye while guiding them onto the uneven and often angled surface of the engine strut 8. This not only causes a fall and the resulting injury, but in the absence of a nacelle fairing, such a fall may cause the engine components to fall.

[0005] In addition, for many installations, the technician on the support column 8 must also directly assist in the installation. The thrust reverser 13 is usually installed via a Figures 3A-3D The hinge assembly 28 is shown attached to the engine strut 8, and once the thrust reverser is guided into position so that a first hinge component 30 (typically a hinge lug) attached to the engine strut is aligned with a second hinge component 32 (typically a hinge clevis) on the thrust reverser, it may be necessary for the technician 26 to reach down and insert the necessary hinge pin 34 into the hinge assembly to secure the thrust reverser to the nacelle, and then install the appropriate nut.

[0006] Therefore, installing such nacelle components represents a delicate and time-consuming operation that requires gently and slowly bringing together and aligning large pieces of aircraft structure as they are suspended from the air. The movement of these components may be guided by hand and eye, and therefore may require workers with excellent judgment, experience, and / or specialized training. In addition, because such an operation may require the use of an overhead crane and the equipment's demand on the factory floor may be high, this operation may create a bottleneck before the operation can be completed.

[0007] What is needed is a system and method to help automate selected aspects of the installation of such large nacelle components, thereby potentially streamlining such processes and improving worker safety. Summary of the invention

[0030] Overview

[0031] Various embodiments of mobile and positioning systems for positioning vehicle components are described below and shown in the relevant drawings. Unless otherwise specified, the disclosed system and / or its various components may, but are not required to, include at least one structure, component, function and / or variation described, shown and / or incorporated herein. In addition, the structures, components, functions and / or variations described, shown and / or incorporated herein in conjunction with the present teachings may, but are not required to be included in other mobile or positioning systems. The following description of various embodiments is essentially exemplary only and is in no way intended to limit the present disclosure, its application or use. In addition, as described below, the advantages provided by the embodiments are illustrative in nature, and not all embodiments provide the same advantages or the same degree of advantages.

[0032] In particular, while the disclosed moving and positioning systems may be illustrated in the context of aircraft manufacturing and moving and positioning engine components for aircraft, the disclosed systems may be used in conjunction with the manufacture and / or assembly of various vehicles or other structures. The present disclosure should not be considered in any way to be limited to the specific applications and examples shown herein.

[0033] Mobile system

[0034] exist Figure 4-9 6. A system 40 for moving vehicle components is shown in FIG. The system 40 may have utility for moving any of a variety of vehicle components, but may be of particular utility for moving vehicle components relative to the structure of the vehicle 6, such as the thrust reverser 13, among other components, and may be particularly helpful in mounting components on the vehicle structure.

[0035] The system 40 may include a base 42 equipped with a plurality of wheels 41, so that the base 42 is movable. The base 42 may further be equipped with one or more base drive mechanisms 43 to supply power to the wheels 41. As depicted in the illustrative embodiment, each wheel 41 may have a dedicated base drive mechanism 43 to supply power to the wheel. Since each base drive mechanism 43 may be driven individually, the base 42 of the system 40 may be manipulated as desired by differentially providing power to each base drive mechanism to move the base 42 in any direction.

[0036] The system 40 includes first and second upright supports 44, 46 spaced apart and mounted to the base 42 so as to be located on opposite sides of a component bay area 48 of the base 42. The first and second supports 44, 46 are mounted to the base 42 such that the first and second upright supports 44, 46 extend upwardly from the base 42.

[0037] The system 40 also includes a lift frame 50, wherein the lift frame includes a cross-beam 52 extending between the first upright support 44 and the second upright support 46 along a beam axis 54 or a cross-beam cable, wherein the beam axis 54 is defined by a longitudinal axis of the cross-beam 52. The lift frame 50 may also include a pair of spaced-apart and arcuate truss assemblies 56 secured to the cross-beam 52, wherein the truss assemblies 56 are configured to attach to and support the vehicle component 14 relative to the cross-beam 52.

[0038] The system 40 also includes a first beam support assembly 58 and a second beam support assembly 60 movably coupled to the first upright support 44 and the second upright support 46, such that the first beam support assembly 58 and the second beam support assembly 60 are configured to support the beam 52 and are movable along the first upright support 44 and the second upright support 46. The first beam support assembly 58 and the second beam support assembly 60 are configured to support the beam 52 relative to the first upright support 44 and the second upright support 46. The first beam support assembly 58 and the second beam support assembly 60 may include a tubular outer support beam 62 extending between the first upright support 44 and the second upright support 46, and more specifically, the support beam 62 may be configured such that the tubular outer support beam 62 surrounds the beam 52.

[0039] like Figure 6As shown, the first cross-beam support assembly 58 and the second cross-beam support assembly 60 are at least substantially enclosed within the first upright support 44 and the second upright support 46, respectively, while supporting an external support beam 62 external to the upright supports. In one aspect of the present disclosure, the first support member 72, the first cross-beam support assembly 58, and the cross-beam 52 are configured to allow the cross-beam 52 to pivot about a first pivot axis 64 that is transverse to the beam axis 54. In the preferred embodiment shown, the pivot axis 64 is fixed relative to the upright support 44. In some embodiments, such as when the first and second cross-beam support assemblies are reversed, the first cross-beam support assembly 58 and the cross-beam 52 can be collectively configured to allow the cross-beam 52 to move laterally relative to the first support member 72, as shown by the second cross-beam support assembly 60 in the illustrated embodiment.

[0040] The system 40 includes a first lifting mechanism 66 configured to move the first cross-beam support assembly 58 along the first upright support 44 in response to a first control signal and a rotation drive mechanism 68 configured to rotate the cross-beam 52 about the beam axis 54 relative to the first cross-beam support assembly 58 and the second cross-beam support assembly 60 in response to a second control signal. The first cross-beam support assembly 58 and the second cross-beam support assembly 60 are configured to support the cross-beam 52 as the cross-beam 52 rotates about the axis 54 and pivot about the axes 64 and 86 relative to the first upright support 44 and the second upright support 46.

[0041] The first cross-beam support assembly 58 includes a first cross-beam support element 70, shown as part of the outer support beam 62, supporting the cross-beam 52, a first support member 72 supported by the first lifting mechanism 66 for movement along the first upright support 44 along a first lifting cable 74, and a pivot pin 76 pivotally coupling the first cross-beam support element 70 to the first support member 72. Figure 5 As shown, the first lift mechanism 66 may be disposed within the upright support 44 beneath and operably coupled to the first support member 72 .

[0042] The first cross-beam support assembly 58 may also include a sleeve 78 fixedly mounted to one of the first cross-beam support element 70 and the first support member 72 of the outer support beam 62, and a pivot pin 76 pivotally supported in the sleeve 78 and supported by the other of the first cross-beam support element 70 and the first support member 72. In the example shown, the pin 76 is fixedly attached to the outer support beam 62, and the sleeve 78 is fixedly attached to the support member 72, such as by welding, thereby preventing the pin 76, the outer support beam 62 and the cross-beam 52 from moving laterally from the lifting cable 74 along the upright support member 44.

[0043] The system 40 is controlled by an electronic system controller 80 that is operably connected to a plurality of base drive mechanisms 43 and is configured to generate control signals via conductors 87 to the base drive mechanisms 43 to change the position of the base 42 of the system 40 by selectively rotating the base wheels 41 to achieve the desired movement of the base 42.

[0044] The system 40 is controlled by an electronic system controller 80 which is operably coupled to the first lift mechanism 66 and the rotary drive mechanism 68, such as Fig.10 The electronic system controller 80 is configured to generate a first control signal to control the operation of the first lifting mechanism 66 via conductor 81 so that the first beam support assembly 58 moves along the first support member 72. The electronic system controller 80 is similarly configured to generate a second control signal to control the operation of the rotation drive mechanism 68 via conductor 83 so that the beam 52 rotates relative to the first beam support assembly 58. In this way, the electronic system controller 80 is able to change the position of the vehicle component 14 relative to the vehicle 6.

[0045] In one aspect of the present disclosure, the electronic system controller 80 is configured to receive input information associated with a target position of a vehicle component 14, and in response to the received input information, the electronic system controller 80 generates a first control signal, which is used to control the operation of the first lifting mechanism 66 to move the first beam support assembly 58 along the first support member 72, and generates a second control signal, which is used to control the operation of the rotation drive mechanism 68 to rotate the beam 52 relative to the first beam support assembly 58, so that the vehicle component 14 can be rotatably positioned when the vehicle component 14 is supported by the lifting frame 50.

[0046] In one aspect of the present disclosure, second upright support 46, second cross-beam support assembly 60, and cross-beam 52 are collectively configured to allow cross-beam 52 to pivot and move laterally relative to second upright support 46. Second cross-beam support assembly 60 may include second cross-beam support element 79, shown as a portion of outer support beam 62, supporting cross-beam 52, second support member 84 supported by second lift mechanism 82 for movement along second lift cable 75 along second upright support 46, and pivot pin 88 pivotally coupling second cross-beam support element 79 to second support member 84. Figure 5 As shown, the second lift mechanism 82 may be disposed within the upright support 46 beneath and operably coupled to the second support member 84 .

[0047] like Fig.10As shown, the second lifting mechanism 82 is configured to move the second beam support assembly 60 along the second support member 84 in response to a third control signal via the conductor 85. In this aspect of the present disclosure, the electronic system controller 80 can be operably coupled to the second lifting mechanism 82 and configured to generate a third control signal that controls the operation of the second lifting mechanism 82 to move the second beam support assembly 60 along the second support member 84, thereby changing the position of the vehicle component 14 relative to the vehicle 6. Figure 5 As shown, the second lift mechanism 82 may be disposed within the upright support 46 beneath and operably coupled to the second support member 84 .

[0048] In one aspect of the present disclosure, the electronic system controller 80 is configured to receive input information associated with a target position of the vehicle component 14, and in response to the received input information, the electronic system controller 80 generates a first control signal for controlling the operation of the first lift mechanism 66 to move the first cross-beam support assembly 58 along the first support member 72, and generates a second control signal for controlling the operation of the rotation drive mechanism 68 to rotate the cross-beam 52 relative to the first cross-beam support assembly 58 to rotatably position the vehicle component 14 when the vehicle component 14 is supported by the lift frame 50. The second cross-beam support assembly 60 can be configured such that, when the cross-beam 52 rotates relative to the first cross-beam support assembly 58, the cross-beam 52 can freely rotate about a second pivot axis 86 that is transverse to the beam axis 54 by rotating about the second pivot pin 88 when the second cross-beam support assembly 60 is supported by the second pivot pin 88.

[0049] In another aspect of the present disclosure, the system 40 may include an electronic system controller 80 operably coupled to the first lift mechanism 66 and the second lift mechanism 82, wherein the electronic system controller 80 may be configured to generate a first control signal that controls operation of the first lift mechanism 66 to move the first cross-beam support assembly 58 along the first support member 72, and to generate a second control signal that controls operation of the second lift mechanism 82 to move the second cross-beam support assembly 60 along the second support member 84. During movement of the second cross-beam support assembly along the second support member 84, the second cross-beam support element 79, and thereby the outer support beam 62 and cross-beam 52, are permitted to pivot about the axis 86 and, via rotation and lateral movement of the second pivot pin 88 relative to the second support member 84, move laterally along the second support member 84, thereby changing the position of the vehicle component 14 relative to the vehicle 6. It should be appreciated that since the pivot pin 76 is fixed in a lateral position relative to the first support member 72, as shown in FIG. Figure 8As shown, the pivoting of the outer support beam 62 and the cross beam 52 about the pin 76 causes the lateral position of the pin 88 to change. This change is accommodated by the lateral movement of the pin 88 along the second support member 84.

[0050] In this aspect of the system 40, the electronic system controller 80 can be configured to receive input information associated with a target position of the vehicle component 14, and in response to the received input information, generate a first control signal for controlling the operation of the first lifting mechanism 66 to move the first beam support assembly 58 along the first support member 72, and generate a second control signal for controlling the operation of the second lifting mechanism 82 to move the second beam support assembly 60 along the second support member 82.

[0051] By applying appropriate first, second, and optional third electronic signals, the vehicle component 14 can be raised and / or lowered along the first upright support 44 and the second upright support 46, the vehicle component 14 can be pivoted relative to the upright supports about the axes 64 and 86, moved laterally relative to the second upright support 46, and rotated relative to the outer support beam 62 so as to be accurately positioned in a desired position and orientation relative to the vehicle 6. For example and as Fig.11A As shown, the system 40 is shown in combination with the vehicle component 14, wherein the system 40 is positioned such that the vehicle component 14 is disposed within the component bay area 48 of the base 42 of the system 40. In this position, operation of the first lifting mechanism 66, the second lifting mechanism 82, the rotary drive mechanism 68, the first cross-beam support assembly 58, and the second cross-beam support assembly 60 properly positions the truss assembly 56 for attaching the truss assembly 56 to the vehicle component 14.

[0052] like Fig. 11B As shown, after the vehicle component 14 is secured to the truss assembly 56, the first lifting mechanism 66 and the second lifting mechanism 82 are operated to sufficiently raise the vehicle component 14 to allow the system 40 to move freely. Fig. 11C As shown, a rotary drive mechanism 68 may be employed to rotate the vehicle component 14 about the beam axis 54 to a suitable orientation for attachment to the vehicle 6. Fig.11D As shown, movement of the base 42 of the system 40, plus any additional adjustments made by one or more of the first lifting mechanism 66, the second lifting mechanism 82, the rotary drive mechanism 68, the first beam support assembly 58, and the second beam support assembly 60 can be used to basically align the vehicle component 14 for connection to the vehicle 6.

[0053] Positioning system

[0054] In one aspect of the present disclosure, the system 40 for moving vehicle components may find particular utility as a component of a positioning system 90 for positioning an engine component 92 for attachment to an engine 94 of an aircraft 96, an example of which is shown in FIG. Fig.12 Shown in.

[0055] The positioning system 90 may include a work platform 98 that allows a technician or other maintenance personnel to access the attachment points of the engine component 92 to the aircraft 96 without requiring any workers to balance on top of the aircraft structure or stand under a suspended load.

[0056] The positioning system 90 may include some or all of the components for moving the engine component 92, similar to the components for moving the system 40 described above. Specifically, the positioning system 90 may include a base 142 equipped with a plurality of wheels 141, so that the base 142 is movable. The base 142 may be further equipped with one or more base drive mechanisms 143 to supply power to the wheels 141, and in one embodiment of the positioning system 90, each wheel 141 may have a dedicated base drive mechanism 143 to supply power to the wheel, so that the base 42 can be moved in any direction on the work surface 24 as needed.

[0057] The base 142 of the positioning system 90 includes first and second spaced-apart upright supports 144 , 146 mounted to the base 142 so as to be located on opposite sides of a component bay area 148 of the base 142 .

[0058] The positioning system 90 also includes a lifting frame 150 having a frame beam 152 and a truss assembly 156 including a pair of arcuate trusses 158 having respective vertices 160. The trusses 158 may be secured to the frame beam 152 at the vertices 160 at spaced-apart locations. The trusses 158 may also include distal ends 162 that may be configured to be secured to the engine component 92 at spaced-apart locations when secured by the positioning system 90.

[0059] The positioning system 90 also includes a cross-beam support 164 on which the frame cross-beam 152 can be supported to rotate relative to the cross-beam support 164, wherein the cross-beam support 164 is supported by and configured to move relative to the pair of upright supports 144 and 146. In one aspect of the present disclosure, the cross-beam support 164 is configured to span between the pair of upright supports 144 and 146.

[0060] Positioning system 90 includes a lift mechanism 166 configured to move crossbar support 164 along at least one of upright supports 144 and 146. Positioning system 90 additionally includes a rotation drive 168 configured to rotate frame crossbar 152 relative to crossbar support 164, as described with respect to movement system 40.

[0061] With these components, the positioning system 90 is configured to move the engine component 92 so as to place the engine component 92 in a suitable position where it can be attached to the engine 94 of the aircraft 96. In addition, the positioning system 90 includes an alignment assembly 170 for determining how the positioning system 90 should be moved in order to guide the engine component 92 to the suitable position.

[0062] like Fig.13 As shown, the alignment assembly 170 includes one or more laser assemblies 172. The laser assembly 172 is configured to support a first laser 174 and a second laser 176 so that they are spaced a known distance 177 along a reference line 178. The laser assembly 172 is configured to be positioned relative to the engine component 92 by the vertically oriented reference line 178, and the first laser 174 and the second laser 176 are individually adjustable in a plane 180 including the reference line 178 so as to align the laser beam of each of the first laser 174 and the second laser 176 with a target location 182 on the aircraft 96 associated with the aircraft engine 94, respectively. The laser assembly 172 is configured to provide a first indication representing a first angle 184 of a first laser beam 185 of the first laser 174 relative to the reference line 178 and a second indication representing a second angle 186 of a second laser beam 187 of the second laser 176 relative to the reference line 178.

[0063] like Fig.12 As shown, one or more laser assemblies 172 are attached to the work platform 98. Fig.12 Four laser assemblies 172 are depicted associated with the work platform 98 of the positioning system 90 . Fig.12 The laser assembly 172 is shown in a retracted configuration B to protect the laser assembly from collision and accidental damage when securing and / or raising the vehicle component 92.

[0064] Similar to the electronic system controller 80 of the system 40 for moving vehicle components, the alignment assembly 170 for positioning the system 90 also includes a system controller 190 configured to control the operation of the rotation drive 168 to rotate the frame crossbar 152 relative to the crossbar support 164 to rotatably position the engine component 92 when the engine component 92 is secured to the lift frame 150. Fig.14As shown, the system controller 190 is additionally configured to determine a vertical distance 192 between the engine component 92 and the target location 182 on the aircraft 96 based at least in part on the first angle and the second angle and the known distance. The system controller 190 is also configured to control the operation of the lifting mechanism 166 to move the cross beam support 164 along at least one of the upright supports 144 and 146 of the positioning system 90 in a direction that reduces the vertical distance between the engine component 92 and the engine 94.

[0065] Again similar to the movement system 40, the base drive mechanism 143 may be coupled to the system controller 190 such that the system controller 190 may employ the base drive mechanism 143 to move the base 142 along the work surface 24. The system controller 190 may also be configured to determine a horizontal distance 194 between the engine component 92 and the target location 182 on the aircraft 96 based at least in part on the first angle and the second angle and the known distance. The system controller 190 may also be configured to control the operation of the base drive mechanism 143 to move the base 142 along the work surface 24 in a direction that reduces the horizontal distance between the engine component 92 and the engine 94.

[0066] The target location 182 on the aircraft 96 may be the attachment location of the engine component 92. For example, in the case where the engine component 92 is mounted to the aircraft 96 via the hinge assembly 28, the target location 182 on the aircraft 96 may be the location of the first hinge component 30, wherein the hinge assembly 28 includes the first hinge component 30 on the aircraft 96 and the second hinge component 32 on the engine component 92. In this aspect of the present disclosure, the laser assembly 172 may be configured to be positioned relative to the engine component 92, wherein the first laser 174 is positioned adjacent to the second hinge component 32 via a vertically oriented reference line 178, and the first laser 174 and the second laser 176 are arranged in a reference plane 180 including the reference line 178 (with the reference plane 180 being aligned with the reference plane 180). Fig.14 plane) so that the laser beam of each of the first laser 174 and the second laser 176 is aligned with the hinge member 30 on the aircraft 96, respectively.

[0067] In one aspect of the present disclosure, the laser assembly 172 of the positioning system 90 is configured as follows Fig.14 The first laser 174 and the second laser 176 are shown supported in the deployed configuration A so that the first laser 174 can be positioned close to the second hinge component 32 of the hinge assembly 28. Such a close position helps the system controller 190 to accurately position the engine component 92. However, the laser assembly 172 can also be configured to support the first laser 174 and the second laser 176 in the retracted configuration B, as shown. Fig.14As shown, the first laser 174 and the second laser 176 are spaced apart from the engine component 92 so as to protect the first laser 174 and the second laser 176 from collision and damage when the positioning system 90 is moved. Therefore, the system controller 190 can be further configured to control the operation of the base drive mechanism 143 when the first laser 174 and the second laser 176 are in their retracted configurations, for example, as Fig.12 shown.

[0068] Position calculation

[0069] System controller 190 uses first laser 174 and second laser 176 of laser assembly 172 to calculate the distance and orientation between a location on engine component 92 , such as second hinge component 32 , and a target location 182 on vehicle 96 , such as first hinge component 30 .

[0070] The laser assembly 172 may be disposed proximate to the engine component 92, with one of the first laser 174 and the second laser 176 adjacent to the second hinge component 32. Fig.14 As shown in the semi-schematic diagram, Fig.14 A laser assembly 172 is shown including a first laser 174 and a second laser 176 adjacent to the engine component 92. Fig.13 and Fig.14 As shown, after proper deployment, the first laser and the second laser are arranged along the reference line 178 and are further arranged to be spaced apart from each other by a known distance 177. As shown, in order to determine the relative position of the engine component 92 relative to the target location 182, the laser beams 185 and 198 emitted by the first laser 174 and the second laser 176, respectively, are each aligned with the target location 182. In doing so, the reference line 178 (side a), the first laser beam 185 (side b), and the second laser beam 187 (side c) form a typical scalene triangle or equilateral triangle having three sides, whose vertices correspond to the target location 182 and the first laser 174 and the second laser 176.

[0071] The first laser 174 and the second laser 176 are configured such that when their respective laser beams 185 and 187 are aligned with the target location 182, the elevation angle of each laser beam above the horizontal plane is determined by angle indicators 200 and 202, respectively. Using the elevation angles, the angle 184 between the first laser beam 185 and the reference line 178 and the angle 186 between the second laser beam 187 and the reference line 178 can be easily calculated. Once the angles 184 and 186 are known, the third angle 204 between the first laser beam 185 and the second laser beam 187 at the target location 182 can be easily calculated.

[0072] Since the distance 177 between the first laser 174 and the second laser 176 along the reference line 178 (side a) is also known, the length of the b and c sides can be calculated using the law of sines:

[0073]

[0074] Where A is angle 184, B is angle 186, C is angle 184, and a is the known distance 177 along reference line 178.

[0075] As a hypothetical and illustrative example, assume that the upper laser 174 has been aimed at the target location 182, resulting in the upper laser beam 185 being raised 27 degrees above the horizontal plane. Similarly, the lower laser 176 is aimed at the target location 182, resulting in the lower laser beam 187 being raised 38 degrees above the horizontal plane. The upper laser 174 and the lower laser 176 are vertically separated by a distance of 36 inches (914 mm).

[0076] So, in this example, angle C is 90 degrees + 27 degrees, or 117 degrees. Likewise, angle B is 90 degrees - 38 degrees, or 52 degrees. Therefore, angle A must be 11 degrees - (180(117 + 52)). Since each of angles A, B, and C is now known, and the length of side a is known, the law of sines can be applied to find the lengths of sides b and c:

[0077]

[0078] By solving for the lengths of side b and side c, it can be determined that side b = 149 inches (37.8 cm), and side c = 168 inches (42.7 cm). Using trigonometric functions, the horizontal distance from the upper laser 174 to the target location 182 is calculated to be 132.8 inches (337.3 cm), and the distance from the lower laser 176 to the target location 182 is calculated to be 132.4 inches (336.3 cm), resulting in an average distance of 132.6 inches. Therefore, it is necessary to move the engine component 92 132.6 inches (336.8 cm) to get closer to the target location 182.

[0079] A similar calculation provides a vertical distance between the upper laser 174 adjacent the second hinge member 32 and the target position 182 of 67.6 inches (172 centimeters). As a confirmatory calculation, the vertical distance between the lower laser 176 and the target position 182 can be calculated to be 103.4 inches (263 centimeters). By subtracting the fixed distance 177 or 36 inches (91 centimeters), the second hinge member 32 must be raised 103.4 inches - 36 inches or 67.4 inches (172 centimeters), substantially the same distance.

[0080] Therefore, the system controller 190 can align the second hinge member 32 with the first hinge member 30 at the target position 182 by controlling the operation of the base drive mechanism 143 to move the engine member 92 forward a distance of 133 inches and controlling the lifting mechanism 166 to raise the engine member 92 a distance of 67 inches. The combined result of the forward movement and upward raising positions the second hinge member 32 on the engine member 92 to be aligned with or adjacent to the first hinge member 30 on the aircraft 96.

[0081] application

[0082] like Fig.15 As shown in flowchart 208 of , the system 40 of the present disclosure may be particularly suitable for performing a method of moving a vehicle component of a vehicle relative to a structure during installation of the component on the structure of the vehicle. The method may include: at step 210 of flowchart 208, attaching a lifting frame to the vehicle component, wherein the lifting frame includes a crossbeam and a pair of spaced-apart arc-shaped truss assemblies attached to the crossbeam, and attaching the lifting frame to the vehicle component includes fixing the pair of truss assemblies to the vehicle component at multiple spaced-apart positions; at step 212 of flowchart 208, supporting a first end of the crossbeam with a first crossbeam support assembly; at step 214 of flowchart 208, in response to a first control signal, causing the first crossbeam support assembly to move along a first support member mounted on a base supported on a work surface and extending upward from the base, thereby causing the first lifting mechanism to move the vehicle component; The tool component moves; at step 216 of flowchart 208, in response to the second control signal, the lifting frame and the attached vehicle component are rotated about the beam axis relative to the first cross-beam support assembly by the rotary drive mechanism to change the orientation of the vehicle component relative to the vehicle; and at step 218 of flowchart 208, the orientation of the vehicle component relative to the vehicle is changed by generating by the electronic controller a first control signal for controlling the operation of the first lifting mechanism to move the first cross-beam support assembly along the first support member and a second control signal for controlling the operation of the rotary drive mechanism to rotate the lifting frame and the attached vehicle component relative to the first cross-beam support assembly.

[0083] In one aspect of the present disclosure, the method of flowchart 208 may also include the following steps: receiving input information by an electronic controller related to the alignment of a first laser and a second laser positioned proximate to a vehicle component relative to a target mounting point on a vehicle structure, the input information representing a target position and orientation of the vehicle component relative to the vehicle structure; generating, in response to the received input information, a first control signal by the electronic controller for controlling the operation of a first lifting mechanism to move a first beam support assembly along a first support member; and generating, in response to the received input information, a second control signal by the electronic controller for controlling the operation of a rotational drive mechanism to rotate the beam and an attached vehicle component relative to the first beam support assembly.

[0084] In another aspect of the present disclosure, the method of flowchart 208 may also include the following steps: receiving input information associated with a target position of a vehicle component by an electronic controller; generating a first control signal for controlling the operation of a first lifting mechanism to move a first beam support assembly along a first support member in response to the received input information; and generating a second control signal for controlling the operation of a rotary drive mechanism to rotate the beam relative to the first beam support assembly to rotationally position the vehicle component when supported by the lifting frame.

[0085] In one aspect of the disclosure, at step 214 of flowchart 208, moving the first cross-beam support assembly along a first support member mounted to and extending upwardly from a base supported on a work surface further includes pivoting the cross-beam relative to the first support member about a first pivot axis transverse to the beam axis. Pivoting the cross-beam relative to the first support member may include: supporting the cross-beam by a first cross-beam support element; supporting the first support member by a first lift mechanism for movement along the first support member along a first lift cable; and pivoting the first cross-beam support element about a pivot pin pivotably coupling the first cross-beam support element to the first support member. The method may also include moving a second cross-beam support element relative to the second support member along a transverse cable transverse to the second lift cable.

[0086] The method of flowchart 208 may also include the step of moving the crossbar transversely to the second support.

[0087] The method of flowchart 208 may further include the following steps: supporting the second end of the beam with a second beam support assembly, the second beam support assembly being movable along a second support member mounted on the base and extending upward from the base; moving the second beam support assembly along the second support member via a second lifting mechanism in response to a third control signal; and generating a third control signal by an electronic controller, the control signal controlling the operation of the second lifting mechanism to move the second beam support assembly along the second support member, thereby changing the position of the vehicle component relative to the vehicle.

[0088] Positioning system 90 may be particularly suitable for performing a method of positioning an engine component for attachment to an engine of an aircraft, such as Fig.16 As shown in flowchart 220. Such a method may include attaching an engine component to a lifting frame including a frame crossbeam and a pair of arc-shaped trusses having respective vertices, the trusses being fixed to the frame crossbeam at spaced-apart positions at their vertices, and at step 222 of flowchart 220, having distal ends fixed to the engine component at spaced-apart positions; at step 224 of flowchart 220, moving the engine component by a lifting mechanism by moving a crossbeam support, in which the frame crossbeam is supported, the crossbeam support being configured to perform relative movement along two upright supports extending upward from a base; at step 226 of flowchart 220, rotating the lifting frame and the attached engine component relative to the crossbeam support by a rotary drive to orient the engine component relative to the engine; at step 228 of flowchart 220, supporting a known distance vertically spaced near the engine component. a first laser and a second laser of the aircraft; at step 230 of flowchart 220, directing a first laser beam emitted by the first laser and a second laser beam emitted by the second laser at a target location on the aircraft associated with an engine of the aircraft; at step 232 of flowchart 220, determining a first angle of the first laser beam relative to a reference line containing the first laser and the second laser, and a second angle of the second laser beam relative to the reference line; at step 234 of flowchart 220, determining, by an electronic system controller having a processor, a vertical distance between the first laser and the target location on the aircraft based at least in part on the first angle and the second angle and the known distance; and at step 236 of flowchart 220, controlling operation of the lifting mechanism to move the crossbeam support along at least one upright support in a direction that reduces the vertical distance between the engine component and the engine.

[0089] In one aspect of the present disclosure, the method of flowchart 220 may further include: determining, by the system controller, a horizontal distance between the engine component and a target location on the aircraft based at least in part on the first angle and the second angle and the known distance; and controlling operation of a base drive mechanism coupled to the system controller and configured to move the base along the work surface in a manner that causes the base to move along the work surface in a direction that reduces the horizontal distance between the engine component and the engine. The method of flowchart 220 may further include: after determining the first angle of the first laser beam and the second angle of the second laser beam and before controlling operation of the base drive mechanism to move the crossbeam support along the work surface, moving the first laser and the second laser away from the engine component.

[0090] At step 228 of the method of flowchart 220, supporting the first laser and the second laser proximate to the engine component may further include positioning the first laser proximate to a first hinge component of a hinge for mounting the engine component to the aircraft, wherein the hinge includes a first hinge component on the engine component and a second hinge component on the aircraft, and the target position on the aircraft is the position of the second hinge component. The method may further include: aligning the first hinge component with the second hinge component and securing the first hinge component to the second hinge component; and then after determining the first angle of the first laser beam and the second angle of the second laser beam and before controlling the operation of the lifting mechanism, moving the first laser and the second laser away from the engine component to move the crossbeam support along at least one upright support in a direction that reduces the vertical distance between the engine component and the engine. When performing the disclosed method, the system controller may be configured to control the operation of the base drive mechanism after the first laser and the second laser have been moved away from the engine component.

[0091] Examples, Parts, and Alternatives

[0092] The following sections describe selected aspects of exemplary motion systems and positioning systems and related methods according to the present disclosure. The examples in these sections are intended to be illustrative and should not be construed as limiting the entire scope of the present disclosure. Each section may include one or more different inventions, and / or contextual or related information, functions and / or structures.

[0093] Example 1: Illustrative Data Processing System

[0094] like Fig.17 As shown, this example describes a data processing system 240 (also referred to as a computer) according to various aspects of the present disclosure. In this example, the data processing system 240 is an illustrative data processing system suitable for implementing various aspects of the mobile system and positioning system of the present disclosure. More specifically, and as described above, in some examples, the mobile system and positioning system may include a system controller (40, 80), which may be or may include one or more data processing systems. When performing the above functions, such as controlling the movement and positioning of vehicle components and / or calculating the relative positioning of engine components relative to a target point, the system controller 40, 80 may exhibit some or all of the features of the data processing system 240 as shown below and described.

[0095] In this illustrative example, data processing system 240 includes communications framework 242. Communications framework 242 provides communications between processor unit 244, memory 246, persistent storage 248, communications unit 250, input / output (I / O) unit 252, and display 254. Memory 246, persistent storage 248, communications unit 250, input / output (I / O) unit 252, and display 254 are examples of resources that processor unit 244 can access via communications framework 242.

[0096] Processor unit 244 is used to run instructions that may be loaded into memory 246. Processor unit 244 may be multiple processors, a multi-processor core, or some other type of processor, depending on the particular implementation. Further, processor unit 244 may be implemented using a number of heterogeneous processor systems in which a main processor is present with one or more secondary processors on a single chip. As another illustrative example, processor unit 244 may be a symmetric multi-processor system containing multiple processors of the same type.

[0097] Memory 246 and persistent storage 248 are examples of storage 256. A storage device is any hardware capable of storing information such as, for example but not limited to, at least one of data, program code in functional form, or other suitable temporary, persistent information.

[0098] Storage 256 may also be referred to as computer-readable storage in these examples. Memory 246 in these examples may be, for example, random access memory or any other suitable volatile or non-volatile storage. Persistent storage 248 may take various forms, depending on the particular implementation.

[0099] For example, persistent storage 248 may include one or more components or devices. For example, persistent storage 248 may be a hard drive, a flash memory, a rewritable optical disk, a rewritable magnetic tape, or some combination thereof. The medium used by persistent storage 248 may also be removable. For example, a removable hard drive may be used for persistent storage 248.

[0100] Communications unit 250, in these examples, provides communications with other data processing systems or devices. Communications unit 250, in these examples, is a network interface card. Communications unit 250 may provide communications through the use of one or both of physical and wireless communications links.

[0101] Input / output (I / O) unit 252 allows input and output of data with other devices that may be connected to data processing system 240. For example, input / output (I / O) unit 252 may provide a connection for user input through at least one of a keyboard, a mouse, or some other suitable input device. In addition, input / output (I / O) unit 252 may send output to a printer. Display 254 provides a mechanism for displaying information to a user.

[0102] Instructions for an operating system (OS), applications (APP) and / or programs may be located in storage 256, which communicates with processor unit 244 via communications framework 242. In these illustrative examples, the instructions are present in functional form on persistent storage 248. These instructions may be loaded into memory 246 for execution by processor unit 244. Processor unit 244 may perform the processes of different embodiments using computer-implemented instructions, which may be located in a memory such as memory 246.

[0103] These instructions are referred to as program instructions, program code, computer usable program code, or computer readable program code, which can be read and executed by a processor in processor unit 244. The program code in different embodiments may be implemented on different physical or computer readable storage media, such as memory 246 or persistent storage 248.

[0104] Program code 258 resides in functional form on computer readable medium 260, which is selectively removable and can be loaded or transferred to data processing system 240 for execution by processor unit 244. In these examples, program code 258 and computer readable medium 260 form computer program product 262. In one example, computer readable medium 260 may be computer readable storage medium 264 or computer readable signal medium 266.

[0105] Computer-readable storage media 264 may include, for example, an optical or magnetic disk that is inserted or placed in a drive or other device that is part of persistent storage 248 for transfer to a storage device, such as a hard drive, that is part of persistent storage 248. Computer-readable storage media 264 may also take the form of a persistent storage device, such as a hard drive, thumb drive, or flash memory, that is connected to data processing system 240. In some cases, computer-readable storage media 264 may not be removable from data processing system 240.

[0106] In these examples, computer-readable storage media 264 is a physical or tangible storage device for storing program code 258, rather than a medium that propagates or transmits program code 258. Computer-readable storage media 264 is also referred to as a computer-readable tangible storage device or a computer-readable physical storage device. In other words, computer-readable storage media 264 is a medium that can be touched by a person.

[0107] Alternatively, program code 258 may be transmitted to data processing system 240 using computer readable signal media 266. Computer readable signal media 266 may be, for example, a propagated data signal containing program code 258. For example, computer readable signal media 266 may be an electromagnetic signal, an optical signal, and / or any other suitable type of signal. These signals may be transmitted via a communication link, such as a wireless communication link, a fiber optic cable, a coaxial cable, a wire, or any other suitable type of communication link. In other words, in the illustrative examples, the communication link and / or connection may be physical or wireless.

[0108] In some illustrative embodiments, program code 258 may be downloaded from another device or data processing system to persistent storage device 248 via computer readable signal media 266 over a network for use within data processing system 240. For example, program code stored in a computer readable storage medium in a server data processing system may be downloaded from the server over a network to data processing system 240. The data processing system providing program code 258 may be a server computer, a client computer, or some other device capable of storing and transmitting program code 258.

[0109] The different components shown for data processing system 240 are not meant to provide architectural limitations to the manner in which different embodiments may be implemented. The different illustrative embodiments may be implemented in a data processing system that includes components in addition to and / or in place of the components shown for data processing system 240. Fig.17 The other components shown in the figure may be different from the illustrative examples shown. The different embodiments may be implemented using any hardware device or system capable of running program code. As an example, data processing system 240 may include organic components integrated with inorganic components and / or may be composed entirely of organic components except for humans. For example, the storage device may be composed of organic semiconductors.

[0110] In another illustrative example, processor unit 244 may take the form of a hardware unit having circuits that are manufactured or configured for specific purposes. This type of hardware can perform operations without the need to load program code from a storage device into memory to be configured to perform the operations.

[0111] For example, when processor unit 244 adopts the form of hardware unit, processor unit 244 can be circuit system, application specific integrated circuit (ASIC), programmable logic device or be configured to perform some other suitable types of hardware of multiple operations.In the case of programmable logic device, the device is configured to perform multiple operations.Can reconfigure the device later, or can permanently configure the device to perform multiple operations.The example of programmable logic device includes, for example, programmable logic array, programmable logic array, field programmable gate array and other suitable hardware devices.By this type of embodiment, program code 258 can be omitted, because the process for different embodiments is realized in hardware unit.

[0112] In yet another illustrative example, processor unit 244 may be implemented using a combination of processors found in computers and hardware units. Processor unit 244 may have multiple hardware units and multiple processors configured to run program code 258. For this depicted example, some processes may be implemented in multiple hardware units, while other processes may be implemented in multiple processors.

[0113] In another example, a bus system can be used to implement the communication framework 242 and can be composed of one or more buses, such as a system bus or an input / output bus. Of course, the bus system can be implemented using any appropriate type of architecture that provides data transmission between different components or devices attached to the bus system.

[0114] In addition, the communication unit 250 may include multiple devices for sending data, receiving data, or both sending and receiving data. The communication unit 250 may be, for example, a modem or a network adapter, two network adapters, or some combination thereof. In addition, the memory may be, for example, a memory 246 or a cache, such as those found in an interface and memory controller hub that may be present in the communication framework 242.

[0115] The flowcharts and block diagrams described herein illustrate the architecture, functions and operations of possible implementations of the systems, methods and computer program products according to various illustrative embodiments. In this regard, each box in the flowchart or block diagram may represent a module, segment or part of code, which includes one or more executable instructions for implementing one or more specified logic or functions. It should also be noted that in some alternative implementations, the functions mentioned in the box may not occur in the order shown in the figure. For example, depending on the functions involved, the functions of the two boxes shown in succession can be performed substantially simultaneously, or the functions of the boxes can sometimes be performed in reverse order.

[0116] Example 2: Illustrative Distributed Data Processing System

[0117] This example describes how Fig.18 A general network data processing system 270 is shown. The network data processing system 270 may be interchangeably referred to as a network, a computer network, a network system, a distributed data processing system, or a distributed network, aspects of which may be included in one or more illustrative embodiments of the mobile system and positioning system of the present disclosure. For example, in other applications, the system controller 40, 80 of the disclosed system may communicate over the network to coordinate with other devices used in a manufacturing facility or to access a processing center remote from the system controller itself.

[0118] It should be understood that Fig.18 This is provided as an illustration of one implementation and is not intended to imply any limitation with respect to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.

[0119] Network data processing system 270 is a network of computers, each of which is an example of data processing system 240 and other components. Network data processing system 270 may include network 272, which is a computer configured to provide communication links between various devices and computers connected together within network data processing system 270. Network 272 may include connections such as wired or wireless communication links, fiber optic cables, and / or any other suitable medium for sending and / or transferring data between network devices, or any combination thereof.

[0120] In the depicted example, first network device 274 and second network device 276 are connected to network 272, as is electronic storage device 278. Network devices 274 and 276 are examples of data processing system 240, respectively, as described above. In the depicted example, devices 274 and 276 are shown as server computers. However, network devices may include, but are not limited to, one or more personal computers, mobile computing devices such as personal digital assistants (PDAs), tablet computers and smart phones, handheld gaming devices, wearable devices, tablet computers, routers, switches, voice gates, servers, electronic storage devices, imaging devices, and / or other networking tools that can perform mechanical or other functions. These network devices may be interconnected by wired, wireless, optical, and other appropriate communication links.

[0121] Additionally, client electronic devices such as client computer 280, client laptop or tablet computer 282, and / or client smart device 284 may be connected to network 272. Each of these devices is an example of data processing system 240, which has been described above with respect to Fig.17Described. Client electronic devices 280, 282, and 284 may include, for example, one or more personal computers, network computers, and / or mobile computing devices, such as personal digital assistants (PDAs), smart phones, handheld gaming devices, wearable devices, and / or tablet computers, etc. In the depicted example, server 274 provides information, such as boot files, operating system images, and applications, to one or more of client electronic devices 280, 282, and 284. Relative to a server such as server computer 274, client electronic devices 280, 282, and 284 may be referred to as "clients." Network data processing system 270 may include more or fewer servers and clients, or no servers or clients, as well as other devices not shown.

[0122] The client intelligent device 284 may include any suitable portable electronic device capable of wireless communication and software execution, such as a smart phone or tablet computer. In general, the term "smart phone" may describe any suitable portable electronic device having higher computing power and network connectivity than a typical mobile phone. In addition to making calls (e.g., via a cellular network), a smart phone may also be capable of sending and receiving emails, text and multimedia messages, accessing the Internet and / or serving as a web browser. Intelligent devices (e.g., smart phones) may also include features of other known electronic devices, such as media players, personal digital assistants, digital cameras, video cameras and / or global positioning systems. Intelligent devices (e.g., smart phones) may be capable of wirelessly, such as via near field communication (NFC), Bluetooth, WiFi or a mobile broadband network, connecting to other intelligent devices, computers or electronic devices. A wireless connection may be established between intelligent devices, smart phones, computers and other devices to form a mobile network that may exchange information.

[0123] Program code located in system 270 may be stored in or on a computer recordable storage medium, such as persistent storage 248 described above, and may be downloaded to a data processing system or other device for use.

[0300] For example, the illustrative embodiments of the movement systems described herein allow large pieces of aircraft structure to be lifted, transported, and placed in position adjacent to the aircraft when installed without the need for overhead cranes or hoists, and without requiring maintenance personnel to manually guide the typically heavy structures. The disclosed movement systems eliminate the need for auxiliary movement aids, such as cranes, hoists, or even muscle strength.

[0301] In addition, among other benefits, the configuration of the base of the illustrative mobile system allows the mobile system to straddle a vehicle component and secure it for lifting while it is held on a pallet or other transport platform. Once secured, the vehicle component can be independently lifted, translated, and rotated while secured so that the vehicle component can be oriented as needed to match the orientation of the aircraft.
