[0010] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0011] In each drawing, the same or corresponding parts are denoted by the same reference numerals. In the description of this embodiment, the description of the same or corresponding parts will be omitted or simplified as appropriate.

[0012] The configuration of an aircraft 10 according to this embodiment will be described with reference to FIG.

[0013] In this embodiment, the air vehicle 10 is a vertical take-off and landing (eVTOL) aircraft that obtains lift and thrust using one or more electric rotors, but may be another type of air vehicle, such as an airplane, helicopter, or glider. "eVTOL" is an abbreviation for electric vertical take-off and landing. The air vehicle 10 can accommodate one or more crew members in its cabin. The air vehicle 10 is operated at least in part under VFR. "VFR" is an abbreviation for visual flight rules. The air vehicle 10 may also be operated under IFR. "IFR" is an abbreviation for instrument flight rules.

[0014] The aircraft 10 comprises a main body 11, main wings 12, and one or more rotors 13. The main wings 12 are attached to the top of the main body 11. In addition to the main wings 12, various other components such as doors, seats, and wheels are attached to the main body 11. The main wings 12 and the tail fins attached to the rear of the main body 11 each have one or more nacelles. Each nacelle is attached with a rotor 13 and contains a drive mechanism including a motor for driving the rotor 13. The rotor 13 corresponds to an electric rotor. The rotor 13 may be of a tilt type. The number of rotors 13 may be any number sufficient to obtain the required thrust. In this embodiment, there are four rotors 13 in total, two on each of the main wings 12 and the tail fin. The number of nacelles is the same as the number of rotors 13. The main wings 12 contain one or more batteries that supply power to the drive mechanism. Similar batteries may also be contained in one or more nacelles. The aircraft 10 may further include known equipment such as avionics and actuators, electrical components such as wire harnesses, and equipment components such as air conditioning ducts and other piping. The avionics may include, for example, computers, flight recorders, and radar.

[0015] 2 to 10, a manufacturing method according to this embodiment, specifically, a method according to this embodiment for assembling the aircraft 10 in a multi-story manufacturing facility 20 in a factory, will be described.

[0016] The manufacturing facility 20 includes a moving mechanism 30. The moving mechanism 30 includes a conveyor 31 that is vertically movable.

[0017] The manufacturing facility 20 includes a fixed floor 41 on the first floor 21. The fixed floor 41 is a floor on which a conveyor 31 is provided. The manufacturing facility 20 includes a fixed floor 42 on the second floor 22, which is higher than the first floor 21. The fixed floor 42 is a floor with a hole 45 drilled therein. The manufacturing facility 20 includes a fixed floor 43 on the third floor 23, which is higher than the second floor 22. The fixed floor 43 is a floor with a hole 46 drilled therein. The manufacturing facility 20 includes a fixed floor 44 on the fourth floor 24, which is higher than the third floor 23. The fixed floor 44 is a floor with a hole 47 drilled therein. The manufacturing facility 20 may further include a warehouse for storing each component of the main body 11 of the aircraft 10, a manufacturing line for each component of the main body 11, or both, on a floor below the first floor 21, i.e., the basement 25. In this embodiment, the fourth floor 24 corresponds to the top floor. Therefore, the rooftop floor 26 is located above the fourth floor 24. A hole 48 is formed in the roof 27 separating the fourth floor 24 from the rooftop floor 26. This hole 48 may be openable and closable to prevent rain from entering the factory.

[0018] The manufacturing method according to this embodiment includes steps S101 to S109 shown in FIG.

[0019] In S101, as shown in FIG. 3 , the main body 11 of the aircraft 10 is assembled on the first floor 21. Specifically, the main body 11 is assembled on the first floor 21 by workers or robots, or by workers and robots working together. Thereafter, on the first floor 21, the assembled main body 11 is placed on a conveyor 31. The main body 11 may move onto the conveyor 31 by self-propelling. While the main body 11 is being assembled, or thereafter, one or more components including the main wing 12 are prepared on the second floor 22. For example, the main wing 12 is supported by a jig 14 placed on the fixed floor 42 and is positioned in a desired position. While the main body 11 is being assembled, or thereafter, other components including the rotor 13 are prepared on the third floor 23.

[0020] In S102, as shown in Fig. 4, the moving mechanism 30 moves the main body 11 to the second floor 22. Specifically, the conveyor 31 carries the main body 11 and moves upward through a hole 45 in the second floor 22, thereby moving the main body 11 to the second floor 22. In this embodiment, the hole 45 in the second floor 22 has a shape that corresponds to the shape of the main body 11. It is desirable that the hole 45 in the second floor 22 is large enough for the main body 11 to pass through, but if it is expected that the position at which the main body 11 is placed on the conveyor 31 will not be constant, the hole 45 may be slightly larger.

[0021] In S103, as shown in Fig. 5, one or more parts including the main wing 12 are attached to the main body 11 on the second floor 22. Specifically, a worker or a robot, or a worker and a robot working together, attaches one or more parts to the main body 11 on the second floor 22. For example, the main wing 12 is rivet-joined to the top of the main body 11. It is desirable that the main wing 12 is positioned at the joining position when it is prepared in S101, but it may also be lowered to the joining position by adjusting the height of the jig 14 in S103.

[0022] In S104, as shown in FIG. 6 , the moving mechanism 30 moves the main body 11, to which one or more parts including the main wing 12 are attached, to the third floor 23. Specifically, the conveyor 31 carries the main body 11, to which one or more parts are attached, and moves upward through the hole 46 on the third floor 23, thereby moving the main body 11, to which one or more parts are attached, to the third floor 23. In this embodiment, the hole 46 on the third floor 23 is larger than the hole 45 on the second floor 22 and has a shape corresponding to the shape of the main body 11, to which one or more parts are attached. It is desirable that the hole 46 on the third floor 23 is large enough to allow the main body 11, to which one or more parts are attached, to pass through. However, if it is expected that the position at which the main body 11, to which one or more parts are attached, is placed on the conveyor 31 will not be constant, the hole 46 on the third floor 23 may be slightly larger.

[0023] In S105, as shown in Fig. 7, on the third floor 23, other parts including the rotor 13 are attached to the main body 11 to which one or more parts including the main wing 12 have been attached, thereby completing the aircraft 10. Specifically, on the third floor 23, a worker or a robot, or a worker and a robot working together, attaches the other parts to the main body 11 to which one or more parts have been attached. For example, the rotor 13 is attached to a nacelle of the main wing 12 and a nacelle of the tail provided at the rear of the main body 11.

[0024] In S106, as shown in FIG. 8 , the movement mechanism 30 moves the aircraft 10 to the fourth floor 24. Specifically, the conveyor 31 carries the aircraft 10 and moves upward through the hole 47 on the fourth floor 24, thereby moving the aircraft 10 to the fourth floor 24. In this embodiment, the hole 47 on the fourth floor 24 is larger than the hole 46 on the third floor 23 and has a shape that corresponds to the shape of the aircraft 10. It is desirable that the hole 47 on the fourth floor 24 be large enough for the aircraft 10 to pass through, but it may be slightly larger if it is expected that the position at which the aircraft 10 is placed on the conveyor 31 will not be constant.

[0025] In S107, the aircraft 10 is inspected on the fourth floor 24. Specifically, the aircraft 10 is inspected on the fourth floor 24 by a worker or a robot, or by a worker and a robot working together.

[0026] In S108, as shown in FIG. 9 , the movement mechanism 30 moves the aircraft 10 to the rooftop floor 26. Specifically, the conveyor 31 carries the aircraft 10 and moves upward through the hole 48 in the roof 27, thereby moving the aircraft 10 to the rooftop floor 26. Thereafter, on the rooftop floor 26, a crew member who pilots the aircraft 10 boards the aircraft 10. In this embodiment, the hole 48 in the roof 27 is approximately the same size as the hole 47 in the fourth floor 24 and has a shape corresponding to the shape of the aircraft 10.

[0027] In S109, as shown in FIG. 10 , the aircraft 10 is taken off from the rooftop floor 26. Specifically, the crew pilots the aircraft 10 on the rooftop floor 26 to vertically take off. The conveyor 31 then moves downward through the hole 48 in the roof 27, the hole 47 in the fourth floor 24, the hole 46 in the third floor 23, and the hole 45 in the second floor 22, thereby returning to its original position on the first floor 21. In this embodiment, after the main body 11 moves to the second floor 22 in S102, the main body 11A of the next aircraft is assembled on the first floor 21, similar to step S101, preferably by the time the conveyor 31 returns to its original position in S109. Then, on the first floor 21, the assembled main body 11A is placed on the conveyor 31 that has returned to its original position. Then, steps similar to steps S102 to S109 are performed for the next aircraft.

[0028] As shown in FIG. 11 , if the hole 45 in the second floor 22 is larger than the size that the main body 11 can pass through, a horizontally movable scaffolding 49 may be provided on the fixed floor 42 as shown in FIG. 12 for workers to attach one or more components, including the main wing 12, to the main body 11. In such a modified example S102, as shown in FIG. 12 , when the moving mechanism 30 moves the main body 11 to the second floor 22, the scaffolding 49 is moved closer to the main body 11 than the periphery of the hole 49 in the second floor 22. As a result, it becomes easier for workers to perform their work. A similar scaffolding may be provided on the fixed floor 43. A similar scaffolding may be provided on the fixed floor 44.

[0029] 13 to 23, a manufacturing method according to a modified example of this embodiment, specifically, a method according to this modified example for assembling the aircraft 10 in a multi-story manufacturing facility 20 in a factory, will be described.

[0030] In this modified example, the moving mechanism 30 has a vertically extendable rod 32 instead of the vertically movable conveyor 31. The number of rods 32 may be one, but in this modified example, there are two or more rods.

[0031] In this modification, the manufacturing facility 20 has multiple vertically movable floors, including a first movable floor 81, instead of multiple fixed floors such as the fixed floor 41. The number of vertically movable floors may be any number equal to or greater than two, but is four in this modification. That is, in addition to the first movable floor 81, the manufacturing facility 20 also has a second movable floor 82, a third movable floor 83, and a fourth movable floor 84. Each vertically movable floor has a hole that closes and becomes caught on the rod 32 only when it is pushed up by the rod 32. As another modification, the manufacturing facility 20 may have only the first movable floor 81. That is, the number of vertically movable floors may be one.

[0032] The manufacturing facility 20 further includes an assembly building 50 where the aircraft 10 is assembled, and a storage building 60 adjacent to the assembly building 50 where each component of the aircraft 10 is stored. At least one floor of the assembly building 50 is connected to at least one floor of the storage building 60. In this modification, the third floor 53 of the assembly building 50, which has a first floor 51, a second floor 52, a third floor 53, and a basement 54, is connected to the third floor 63 of the storage building 60, which has a first floor 61, a second floor 62, a third floor 63, and a basement 64, via a passageway 70. In this modification, the third floor 53 of the assembly building 50 corresponds to the top floor. Therefore, the rooftop floor 55 is located above the third floor 53 of the assembly building 50. A roof 56 separating the third floor 53 of the assembly building 50 from the rooftop floor 55 may be retractable.

[0033] The manufacturing method according to this modification includes steps S201 to S210 shown in FIG.

[0034] In S201, as shown in FIG. 14 , the main body 11 of the aircraft 10 is assembled on the first floor 51 of the assembly building 50. Specifically, workers or robots, or workers and robots working together, assemble the main body 11 on the first movable floor 81 on the first floor 51 of the assembly building 50. Therefore, on the first floor 51 of the assembly building 50, the assembled main body 11 is placed on the first movable floor 81. While the main body 11 is being assembled, or thereafter, one or more components including the main wings 12 are prepared on the second floor 52 of the assembly building 50. For example, the main wings 12 are supported by wires 15 and positioned in a desired position. While the main body 11 is being assembled, or thereafter, other components including the rotors 13 are prepared on the third floor 63 of the storage building 60.

[0035] 15 , the moving mechanism 30 moves the main body 11 to the second floor 52 of the assembly building 50. Specifically, the rod 32 pushes up and moves the first movable floor 81, thereby moving the main body 11 together with the first movable floor 81 to the second floor 52 of the assembly building 50. At this point, the first movable floor 81 is above the second movable floor 82, the third movable floor 83, and the fourth movable floor 84. Therefore, a hole is opened in the first movable floor 81, and the holes in the second movable floor 82, the third movable floor 83, and the fourth movable floor 84 are closed, so that the rod 32 can pass through the second movable floor 82, the third movable floor 83, and the fourth movable floor 84 to push up the first movable floor 81.

[0036] In S203, as shown in FIG. 16 , one or more parts including the main wing 12 are attached to the main body 11 on the second floor 52 of the assembly building 50. Specifically, a worker, a robot, or a collaboration between a worker and a robot attaches one or more parts to the main body 11 on the second floor 52 of the assembly building 50. For example, the main wing 12 is riveted to the upper part of the main body 11. The main wing 12 is preferably positioned at the joining position when prepared in S201, but may be lowered to the joining position by adjusting the length of the wire 15 in S203. In this modification, after the main body 11 is moved to the second floor 52 of the assembly building 50 in S202, the main body 11A of the aircraft 10A is assembled on the first floor 51 of the assembly building 50, similar to step S201, at the earliest by the time one or more parts are attached to the main body 11 in S203. Therefore, on the first floor 51 of the assembly building 50, the assembled main body 11A is placed on the second movable floor 82.

[0037] 17 , the movement mechanism 30 moves the main body 11, to which one or more parts including the main wing 12 are attached, to the third floor 53 of the assembly building 50. Specifically, the rod 32 pushes up and moves the first movable floor 81, thereby moving the main body 11, to which one or more parts are attached, to the third floor 53 of the assembly building 50. At this point, the first movable floor 81 is still above the second movable floor 82, the third movable floor 83, and the fourth movable floor 84. Therefore, holes are opened in the first movable floor 81, and holes in the second movable floor 82, the third movable floor 83, and the fourth movable floor 84 are closed, so that the rod 32 can pass through the second movable floor 82, the third movable floor 83, and the fourth movable floor 84 to push up the first movable floor 81. In this modification, in S204, the main body 11 to which one or more parts are attached is moved to the third floor 53 of the assembly building 50, and then one or more parts including the main wing 12A are prepared on the second floor 52 of the assembly building 50. For example, the main wing 12A is supported by wires 15A and placed in a desired position. Then, as shown in FIG. 18 , the movement mechanism 30 moves the main body 11A to the second floor 52 of the assembly building 50. Specifically, the rod 32 pushes up and moves the second movable floor 82, thereby moving the main body 11A together with the second movable floor 82 to the second floor 52 of the assembly building 50. At this point, the second movable floor 82 is above the third movable floor 83 and the fourth movable floor 84. Therefore, holes are opened in the second movable floor 82 and holes are closed in the third movable floor 83 and the fourth movable floor 84 so that the rod 32 can pass through the third movable floor 83 and the fourth movable floor 84 and push up the second movable floor 82. While or after the main body 11 with one or more parts attached is being moved, other parts including the rotor 13A are transported from the third floor 63 of the storage building 60 to the third floor 53 of the assembly building 50 via the corridor 70. On the third floor 63 of the storage building 60, other parts including the rotor 13A are prepared.

[0038] In S205, as shown in FIG. 19 , on the third floor 53 of the assembly building 50, other parts including the rotor 13 are attached to the main body 11, to which one or more parts including the main wing 12 have been attached, thereby completing the aircraft 10. Specifically, on the third floor 53 of the assembly building 50, a worker or a robot, or a worker and a robot work together, attaches other parts to the main body 11, to which one or more parts have been attached. For example, the rotor 13 is attached to a nacelle of the main wing 12 and a nacelle of a tail unit provided at the rear of the main body 11. In this modification, after the main body 11A is moved to the second floor 52 of the assembly building 50, one or more parts including the main wing 12A are attached to the main body 11A on the second floor 52 of the assembly building 50, as in step S203, at the earliest by the time the aircraft 10 is completed in S205. In this modification, after the main body 11A has been moved to the second floor 52 of the assembly building 50, the main body 11B of the next aircraft is assembled on the first floor 51 of the assembly building 50, as in step S201, at the earliest by the time one or more parts are attached to the main body 11A. Therefore, on the first floor 51 of the assembly building 50, the assembled main body 11B is placed on the third movable floor 83.

[0039] In S206, as shown in Fig. 20, the movement mechanism 30 moves the aircraft 10 horizontally. Specifically, the movement mechanism 30 moves the aircraft 10 horizontally by sliding the aircraft 10 together with the first movable floor 81 toward the front side of Fig. 20 in a manner similar to that of a mechanical multi-story parking garage.

[0040] In S207, the aircraft 10 is inspected on the third floor 53 of the assembly building 50. Specifically, the aircraft 10 is inspected on the third floor 53 of the assembly building 50 by a worker or a robot, or by a worker and a robot working together.

[0041] In S208, the moving mechanism 30 moves the aircraft 10 to the first floor 51 of the assembly building 50. Specifically, the moving mechanism 30 moves the aircraft 10 together with the first movable floor 81 downward using a mechanism similar to that of a mechanical multi-story parking garage, thereby moving the aircraft 10 to the first floor 51 of the assembly building 50. Thereafter, on the first floor 51 of the assembly building 50, a crew member who will pilot the aircraft 10 boards the aircraft 10.

[0042] In S209, the aircraft 10 is moved outside the factory. Specifically, a towing vehicle tows the aircraft 10 on the first floor 51 of the assembly building 50 to move the aircraft 10 outside the factory. Alternatively, a crew member may pilot the aircraft 10 on the first floor 51 of the assembly building 50 to move the aircraft 10 outside the factory.

[0043] In S210, the aircraft 10 is caused to take off outside the factory. Specifically, a crew member pilots the aircraft 10 outside the factory and causes the aircraft 10 to take off vertically. Thereafter, the travel mechanism 30, using a mechanism similar to that of a mechanical multi-story parking garage, slides the first movable floor 81 in the opposite direction from that in S206, thereby returning the first movable floor 81 to its original position on the first floor 51 of the assembly building 50. In this modification, after the aircraft 10 moves horizontally in S206, as shown in FIG. 21 , the travel mechanism 30 moves the main body 11A, to which one or more parts including the main wing 12A are attached, to the third floor 53 of the assembly building 50. Specifically, the rod 32 pushes up and moves the second movable floor 82, thereby moving the main body 11A, to which one or more parts are attached, together with the second movable floor 82, to the third floor 53 of the assembly building 50. At this point, the second movable floor 82 is still above the third movable floor 83 and the fourth movable floor 84. Therefore, holes are opened in the second movable floor 82, and holes in the third movable floor 83 and the fourth movable floor 84 are closed, so that the rods 32 can pass through the third movable floor 83 and the fourth movable floor 84 and push up the second movable floor 82. In this modification, after the main body 11A to which one or more parts are attached is moved to the third floor 53 of the assembly building 50, one or more parts including the main wing 12B are prepared on the second floor 52 of the assembly building 50. For example, the main wing 12B is supported by wires 15B and placed in a desired position. Then, as shown in FIG. 22 , the movement mechanism 30 moves the main body 11B to the second floor 52 of the assembly building 50. Specifically, the rods 32 push up and move the third movable floor 83, thereby moving the main body 11B together with the third movable floor 83 to the second floor 52 of the assembly building 50. At this point, the third movable floor 83 is above the fourth movable floor 84. Therefore, a hole is opened in the third movable floor 83 and a hole is closed in the fourth movable floor 84 so that the rod 32 can pass through the fourth movable floor 84 and push up the third movable floor 83. While or after the main body 11A with one or more parts attached is being moved, other parts including the rotor 13A are transported from the third floor 63 of the storage building 60 to the third floor 53 of the assembly building 50 via the corridor 70. On the third floor 63 of the storage building 60, other parts including the rotor 13B are prepared.23, on the third floor 53 of the assembly building 50, other components including the rotor 13A are attached to the main body 11A, to which one or more components including the main wing 12A have been attached, thereby completing the aircraft 10A. Then, steps similar to steps S206 to S210 are performed for the aircraft 10A. In this modification, after the main body 11B is moved to the second floor 52 of the assembly building 50, one or more components including the main wing 12B are attached to the main body 11B on the second floor 52 of the assembly building 50, as in step S203, at the earliest by the time the aircraft 10A is completed. Then, steps similar to steps S204 to S210 are performed for the next aircraft. In this modification, after main body 11B has been moved to second floor 52 of assembly building 50, main body 11C of the next aircraft is assembled on first floor 51 of assembly building 50, similar to step S201, at the earliest by the time one or more parts are attached to main body 11B. Therefore, on first floor 51 of assembly building 50, assembled main body 11C is placed on fourth movable floor 84. Then, steps similar to steps S202 to S210 are performed for the next aircraft.

[0044] As shown in FIG. 24 , the movement mechanism 30 may have rails 33 that slidably support a vertically movable floor instead of the vertically extendable rod 32. The number of rails 33 is two or more. In S202 of such a modification, as shown in FIG. 24 , the movement mechanism 30 slides the first movable floor 81 along the rails 33, thereby moving the main body 11 together with the first movable floor 81 to the second floor 52 of the assembly building 50. After moving the first movable floor 81 to the second floor 52 of the assembly building 50, the movement mechanism 30 locks the first movable floor 81 in S203 until the installation of one or more components on the main body 11 is completed. After unlocking the first movable floor 81 in S204, the movement mechanism 30 further slides the first movable floor 81 along the rails 33, thereby moving the first movable floor 81 to the third floor 53 of the assembly building 50. After the moving mechanism 30 moves the first movable floor 81 to the third floor 53 of the assembly building 50, it locks the first movable floor 81 in S205 until the work of completing the aircraft 10 is completed. The operations of locking and unlocking the second movable floor 82, the third movable floor 83, and the fourth movable floor 84 are similar to the operations of locking and unlocking the first movable floor 81, and therefore will not be described here. When the moving mechanism 30 has a rod 32, the moving mechanism 30 may lock and unlock the first movable floor 81, the second movable floor 82, the third movable floor 83, and the fourth movable floor 84, just as when the moving mechanism 30 has rails 33.

[0045] In S206, the movement mechanism 30 horizontally moves the completed aircraft 10 on the top floor. However, as another variation, the movement mechanism 30 may horizontally move an incomplete aircraft 10 on the top floor. For example, the second floor 52 of the assembly building 50 may correspond to the top floor. In such a case, the movement mechanism 30 may horizontally move the main body 11, to which one or more parts have been attached, on the top floor. In such a variation, other parts are attached to the horizontally moved main body 11 to which one or more parts have been attached, thereby completing the aircraft 10. The movement mechanism 30 then moves the completed aircraft 10 downward. Alternatively, the movement mechanism 30 may simply move the horizontally moved main body 11, to which one or more parts have been attached, downward. Then, other parts are attached to the downward moved main body 11 to which one or more parts have been attached, thereby completing the aircraft 10. Inspection of the aircraft 10 is carried out on the same floor or a lower floor after the aircraft 10 is completed.

[0046] If the roof 56 is retractable, the completed aircraft 10 may be inspected on the top floor, and the aircraft 10 may take off immediately after inspection is complete. Alternatively, the transportation mechanism 30 may move the aircraft 10 after inspection is complete to the rooftop floor 55 by any method, and the aircraft 10 may then take off on the rooftop floor 55. Alternatively, the transportation mechanism 30 may further move the aircraft 10 from the rooftop floor 55 to the storage building 60, and the aircraft 10 may then take off on the rooftop floor of the storage building 60.

[0047] If the roof 56 is retractable, the flying object that has landed on the top floor may be serviced on the top floor, and then the moving mechanism 30 may move the flying object downward. Alternatively, the moving mechanism 30 may move the flying object that has landed on the top floor downward, and the flying object that has moved downward may be serviced on a floor below the top floor.

For example, two or more steps shown in the flowchart may be executed in parallel or in a different order as needed, instead of being executed in chronological order as described. Other modifications are possible without departing from the spirit of the present disclosure.
