Description

[Technical Field]

[0001] The present disclosure relates to a takeoff assistance method for an aircraft. [Background technology]

[0002] BACKGROUND ART Conventionally, there has been disclosed an apparatus that has an air current airplane that floats by air currents and that can take off the air current airplane (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 06-014995 Summary of the Invention [Problem to be solved by the invention]

[0004] Until now, there has been no research into technology to assist the takeoff of battery-powered aircraft, meaning there is room for improvement in takeoff support technology for battery-powered aircraft.

[0005] In view of the above circumstances, the purpose of the present disclosure is to improve takeoff assistance technology for battery-powered flying vehicles. [Means for solving the problem]

[0006] A takeoff assistance method for an aircraft according to an embodiment of the present disclosure is a takeoff assistance method for an aircraft at the time of takeoff, When a battery-powered flying object having electric rotors takes off, a charging cable is connected to the flying object to charge the battery while it is lifted, and the flying object is towed by the charging cable to assist its lift. [Effects of the Invention]

[0007] According to one embodiment of the present disclosure, takeoff assistance techniques for battery-powered air vehicles are improved. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 1 is a diagram illustrating an overview of a takeoff assistance technology for an aircraft according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

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

[0010] (Outline of the embodiment) An overview of a takeoff assistance method according to an embodiment of the present disclosure will be described with reference to Fig. 1. The takeoff assistance method according to an embodiment of the present disclosure is a method for assisting the takeoff of a battery-powered aircraft 10. Fig. 1 shows an overview of a takeoff assistance technology for an aircraft according to an embodiment of the present disclosure.

[0011] The aircraft 10 flies on battery power. The aircraft 10 includes passenger aircraft, airplanes, helicopters, drones, etc. For example, the aircraft 10 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 aircraft 10 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 aircraft 10 may be operated under instrument flight rules (IFR). The aircraft 10 also has communication capabilities and information processing capabilities, and is connected to a network via a mobile communication network.

[0012] 1, the aircraft 10 is connected at takeoff by a charging cable 20. The other end of the charging cable 20 is connected to a winch 30 (hoisting machine 30).

[0013] A takeoff assistance method according to an embodiment of the present disclosure assists takeoff of a battery-powered aircraft 10 having electric rotors by connecting a charging cable 20 to the aircraft 10 while charging it and lifting it up, and by winding up the charging cable 20 with a winch 30 to tow the aircraft 10 and assist the aircraft 10 in lifting. At this time, the aircraft 10 drives the electric rotors. This allows the aircraft 10 to lift up due to the combined force of the lift force caused by the pulling of the charging cable 20 and the lift force caused by the electric rotors. According to this embodiment, the aircraft 10 is connected to the charging cable 20, so it can take off while charging. The charging cable 20 is also wound up by the winch 30. Based on the lift force generated by winding up the charging cable 20, the aircraft 10 gradually lifts up as shown in (a) to (c) of FIG. 1 .

[0014] As described above, according to this embodiment, when a battery-powered aircraft 10 with electric rotors takes off, the charging cable 20 is connected and the aircraft is allowed to rise while charging. The aircraft is also towed by the charging cable 20 to assist its rise. In other words, the aircraft 10 connected to the charging cable 20 is assisted in rising by being towed by a winch. In this way, takeoff assistance technology for battery-powered aircraft 10 is improved.

[0015] In this embodiment, an example in which the charging cable 20 is connected to the aircraft 10 has been described, but this is not limiting. In addition to the charging cable 20, a cooling cable may be connected to the aircraft 10. The cooling cable is a cable through which a refrigerant circulates, and has the function of dissipating heat generated when the aircraft 10 is being charged. By connecting the cooling cable, heat generation during charging can be suppressed.

[0016] Instead of towing the aircraft 10 with the charging cable 20, a wire may be connected to the aircraft 10 and the wire may be pulled by the winch 30 to assist the aircraft 10 in taking off. In this case, the length of the wire is shorter than the length of the charging cable 20. If a cooling cable is connected to the aircraft 10, the length of the wire is shorter than the length of the cooling cable. This allows the aircraft 10 to be towed by the wire while reducing tension on the charging cable 20 or the cooling cable. In this case, the radius of the winch winding the charging / cooling cable may be larger than the radius of the winch winding the wire. This prevents damage to the charging / cooling cable. The predetermined location of the aircraft 10 secured by the wire may be, for example, the lift generating part of the aircraft 10. The predetermined location may also be the axle of the aircraft 10. The lift generating part and the axle are driving parts of the aircraft 10 and are highly durable. Therefore, they are suitable for securing by wire.

[0017] 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.
