DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described.

[0010] (Outline of the embodiment) An overview of a securing method according to an embodiment of the present disclosure will be described with reference to FIG. 1. The securing method according to an embodiment of the present disclosure is a method for securing a battery-powered aircraft 20 by a mobile body 1 such as a ship or a vehicle during sea or land transport. FIG. 1 shows an example of a securing method during sea transport, in which the mobile body 1 is a ship. The mobile body 1 has a storage area 10 for storing the aircraft 20. As shown in FIG. 1, multiple aircraft 20 are stored in the storage area 10 of the mobile body 1. In FIG. 1, four aircraft 20 are stored in the storage area 10, but the number of stored aircraft 20 is not limited to this and may be less than four or may be five or more.

[0011] The air vehicle 20 flies on battery power. Examples of the air vehicle 20 include passenger planes, airplanes, helicopters, drones, etc. For example, the air vehicle 20 has a cabin approximately the same size as a passenger car that can accommodate one or more occupants, and a mechanism including one or more electric rotors for generating lift and thrust, and is operated at least partially under visual flight rules (VFR), such as an electric vertical take off and landing (eVTOL). The air vehicle 20 has a drive mechanism including a motor for driving the electric rotor, a control device for the drive mechanism, and a battery for supplying power to the drive mechanism. The battery is, for example, a lithium-ion battery. The air vehicle 20 may be operated under instrument flight rules (IFR). The air vehicle 20 also has communication capabilities and information processing capabilities, and is connected to a network via a mobile communication network.

[0012] First, an overview of this embodiment will be described, and details will be provided later. As shown in Fig. 1, the fixing method according to the embodiment of the present disclosure connects and fixes predetermined locations of the flying body 20 and the moving body 1 with wires 31, 32, 33, and 34. Note that in Fig. 1, each moving body 20 is fixed with four wires, but this is not limited to this. The number of wires for fixing each flying body 20 may be less than four, or may be five or more.

[0013] As described above, according to this embodiment, the mobile body 1 and the flying body 20 are connected and fixed at predetermined locations by wires. Therefore, the flying body 20 is appropriately positioned in the storage area 10 of the mobile body 1. This protects the flying body 20 from shaking during transportation and vibrations and shocks caused by acceleration and deceleration during transportation, thereby preventing damage, deformation, breakage, etc., of the flying body 20. In this way, the technology for marine and land transportation of battery-powered flying bodies is improved.

[0014] Next, a fixing method according to an embodiment of the present disclosure will be described in detail.

[0015] FIG. 2 is a diagram showing an air vehicle 20 secured by a securing method according to an embodiment of the present disclosure. As shown in FIG. 2 , the predetermined locations of the air vehicle 20 secured by wires 31, 32, 33, and 34 may be, for example, the lift generating units 21 and 22 of the air vehicle 20. Furthermore, such predetermined locations may be the axles 23 and 24 of the air vehicle 20. The lift generating units 21 and 21, as well as the axles 23 and 24, are driving parts of the air vehicle 20 and are highly durable. Therefore, they are suitable for securing by wires 31, 32, 33, and 34. The other ends of the wires 31 and 32 are connected to the ceiling 11 of the storage area 10 of the moving body 1. The other ends of the wires 33 and 34 are connected to the floor 12 of the storage area 10 of the moving body 1. In the example shown in FIGS. 1 and 2 , the air vehicle 20 is suspended in the storage area 10. This prevents vibrations or shocks from being transmitted from the floor 12 to the flying object 20. The flying object 20 does not have to be suspended in mid-air. For example, the flying object 20 may be in contact with the floor 12.

[0016] FIG. 3 is a schematic diagram of the lift generating unit 21 of the aircraft 20 according to an embodiment of the present disclosure. The lift generating unit 21 of the aircraft 20 according to this embodiment includes a propeller rotating shaft 211, a propeller 212, and a propeller connecting unit 213. For example, the wire 31 may be connected to the propeller rotating shaft 211. A fairing fitting such as a thread is provided on the upper part of the propeller rotating shaft 211. The propeller rotating shaft 211 may be connected to the wire 31 using the fairing fitting. Specifically, for example, during transportation, the fairing of the propeller rotating shaft 211 is removed, and a wire connecting member is attached to the fairing fitting. The end of the wire 31 on the aircraft side is connected to the wire connecting member. The wire connecting member has a fitting such as a thread that corresponds to the fairing fitting. In this way, the propeller rotating shaft 211 of the lift generating unit 21 can be used as the predetermined location for connecting the wire. The lift generating unit 22 has a similar structure, and therefore a description thereof will be omitted.

[0017] The predetermined location fixed by the wires may be another location on the lift generating unit 21. For example, the predetermined location may be the propeller connecting unit 213. When the predetermined location is the propeller connecting unit 213, the propeller connecting unit 213 may be fixed by being sandwiched from both side surfaces by a plurality of wires. FIG. 4 is a schematic diagram showing an example of a method for fixing the propeller connecting unit 213. As shown in FIG. 4, the propeller connecting unit 213 may be fixed by being sandwiched between wires 311 and 312.

[0018] The predetermined location of the aircraft 20 fixed by the wire may be another part of the lift generating unit 21. FIG. 5 is a schematic diagram showing the motor housing unit 214 and the structural member 215 of the lift generating unit 21 of the aircraft according to one embodiment of the present disclosure. As shown in FIG. 5, the lower end of the propeller rotation shaft 211 of the lift generating unit 21 is connected to the motor housing unit 214. An electric rotor for generating lift and thrust is provided inside the motor housing unit 214. The motor housing unit 214 is provided on a structural member 215 that connects to the fuselage of the aircraft 20. For example, the predetermined location of the aircraft 20 fixed by the wire may be the motor housing unit 214. Alternatively, the predetermined location of the aircraft 20 fixed by the wire may be the structural member 215 that connects the lift generating unit 21 to the fuselage.

[0019] As described above, according to this embodiment, predetermined locations of the flying object 20 are connected and fixed to the moving object 1 by wires. Therefore, the flying object 20 is appropriately positioned in the storage area of the moving object 1. This protects the flying object 20 from shaking during transportation and vibrations and shocks caused by acceleration and deceleration during transportation, thereby preventing damage, deformation, breakage, etc. of the flying object 20. In this way, the technology for marine and land transportation of battery-powered flying objects is improved.

[0020] Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art may make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present disclosure. For example, the functions included in each component or step can be rearranged so as not to be logically inconsistent, and multiple components or steps can be combined or divided into one.

[0021] For example, the predetermined location of the aircraft 20 fixed by the wire may be a ground installation part or a jack-up point. Also, if the lift generating part of the aircraft 20 has a tilt axis, the predetermined location of the aircraft 20 fixed by the wire may be the tilt axis.

[0022] In one example, the aircraft 20 may be used to provide MaaS (Mobility as a Service), a service that utilizes mobility. [Explanation of symbols]
