Description

[0001] The invention relates to a passenger drone for transporting winter sports enthusiasts with strapped-on winter sports equipment, comprising a cargo drone, wherein a suspension device can be attached, preferably detachably, to the cargo drone. Furthermore, the invention relates to a method for transporting winter sports enthusiasts, in particular with strapped-on winter sports equipment, with at least one passenger drone.

[0002] Passenger drones, also known as autonomous flying taxis, are already known in the state of the art. They are characterized by the ability to transport passengers and the ability to fly autonomously, as is known from unmanned aerial vehicles. Flyable models with an enclosed passenger cabin are already known in the state of the art, such as the EHang 184 model for one passenger and the EHang 216 model for two passengers.

[0003] The patent application WO 2020/184602 A1 shows a passenger drone for rescuing people, whereby a person can be transported standing in an open sling on a cargo drone.

[0004] The transportation of winter sports enthusiasts to a higher exit point is usually accomplished by lifts or cable cars. A disadvantage of transport by lifts or cable cars is that the exit point is fixed at the mountain station. This makes it impossible to achieve a personalized descent, as desired by off-piste skiers or freeriders.

[0005] An alternative is the transport of winter sports enthusiasts by helicopter, a process also known as heliskiing/snowboarding. Here, a pilot takes one or more winter sports enthusiasts to a chosen exit point, often a summit. The disadvantage of this method is the high cost, which is caused, among other things, by the high fuel consumption and the need for a pilot. In addition, heliskiing/snowboarding pollutes the environment through loud engine noise and exhaust fumes from the helicopter. Therefore, heliskiing/snowboarding is prohibited in many areas, particularly in most parts of the Alps.

[0006] These disadvantages can be partially avoided by using passenger drones to transport winter sports enthusiasts. Patent application WO 2019/209132 A1 shows the use of a passenger drone with a closed cabin in the mountains, particularly disclosing its use by winter sports enthusiasts for off-piste skiing or freeriding.

[0007] However, a disadvantage is that exiting the passenger drone is difficult in impassable, steep, and/or exposed terrain, such as on narrow peaks or ridges or in steep gullies, where landing is not possible. Winter sports enthusiasts therefore often have to exit a flying passenger drone. Since there is no space in passenger drones to strap on winter sports equipment, such as skis or snowboards, winter sports enthusiasts must exit without strapped-on winter sports equipment and strap on the winter sports equipment in the terrain. This poses a significant safety risk for the winter sports enthusiast in impassable, steep, and/or exposed terrain. Entry into the passenger drone is also difficult.

[0008] It is an object of the present invention to avoid these disadvantages. In particular, it is an object of the present invention to provide a passenger drone that enables safe egress in exposed terrain.

[0009] Therefore, in a passenger drone according to the invention, at least one chair for at least one winter sports enthusiast can be attached to the suspension.

[0010] A method according to the invention provides for the transport of winter sports enthusiasts, in particular with strapped-on winter sports equipment, with at least one such passenger drone.

[0011] This allows a winter sports enthusiast to be transported with at least partially strapped-on winter sports equipment, similar to a chairlift. This allows for safe disembarkation from the passenger drone in steep terrain. Jumping from the

Drone in particularly inaccessible places.

[0012] In one embodiment, a safety bar is arranged on at least one chair and/or on the suspension system. This protects a winter sports enthusiast from falling out of the chair during transport. Preferably, a footrest is arranged on the safety bar. A winter sports enthusiast can rest his feet, in particular his strapped-on winter sports equipment, on this.

[0013] The safety bar can be pivotable and thus have an open and a closed position. This allows a winter sports enthusiast to board and disembark with the safety bar open, while the safety bar can be closed during a passenger drone flight.

[0014] The footrest can also be attached directly to the chair and/or the suspension.

[0015] The suspension system can have a curved shape, at least in sections. This allows the suspension system to also be used for a chair on a chairlift.

[0016] The seat and/or the suspension system can be made at least partially, preferably largely, of fiber-reinforced plastic, in particular carbon-fiber-reinforced plastic. This keeps the dead weight of the passenger drone low while simultaneously achieving a stable design.

[0017] A parking device can preferably be arranged on the suspension and/or the chair, wherein the parking device extends into an area below the at least one chair and/or the suspension. This allows the chair and/or the suspension or the entire passenger drone to be parked. The cargo drone can be uncoupled in this case. The cargo drone can also be coupled and switched off.

[0018] Preferably, the parking device has at least one skid and/or at least one wheel. A skid allows the passenger drone or the chair and/or the suspension to be moved in the snow. A wheel allows the passenger drone or the chair and/or the suspension to be moved on snowless ground.

[0019] It may also be provided to use the parking device as a footrest. For this purpose, a cross brace may be provided on the parking device.

[0020] In one embodiment, the cargo drone has a connecting part, wherein the hanger can be attached to the cargo drone with the connecting part.

[0021] In one embodiment, the suspension has a fastening device for connection to the cargo drone at the end opposite at least one chair.

[0022] The attachment device can be used to attach the suspension device to the cargo drone, preferably detachably. Various attachment methods are conceivable.

[0023] A joint can be arranged between the cargo drone and the suspension. The joint is preferably designed as a hinge, pivot bearing, universal joint, or ball joint. This allows the suspension to hang straight down despite the cargo drone being tilted, for example, during flight.

[0024] Such a joint can be arranged on the fastening device and/or on the connecting part and/or on the hanger.

[0025] The joint can be designed to be lockable. For example, it can be provided that the joint is locked when the passenger drone lands, so that a switched-off cargo drone does not tip over. The locking of the joint can be electronic and/or mechanical, and automatic and/or manual.

[0026] The joint can be damped. This can reduce or prevent vibration of the suspension during flight of the passenger drone.

[0027] A weight detection device can be arranged between the cargo drone and the suspension system, preferably comprising strain gauges. This can be used to measure whether one and/or more winter sports enthusiasts are sitting in the passenger drone's seat. It can also be detected whether at least one winter sports enthusiast has exited.

[0028] It may be provided that the suspension device can be attached to the cargo drone via a cable section and/or a rail. Thus, fastening devices commonly used in chairlifts can be used to attach the suspension device to the cargo drone.

[0029] The suspension device can be attached to the cargo drone via a clamp, preferably with the clamp being held in a closed position by a spring and/or being transferable from a closed position to an open position by means of an actuating lever. The clamp can be designed according to a configuration commonly used in chairlifts. By actuating the actuating lever, the suspension device can be released from the cargo drone. In particular, it is provided that the clamp can be attached to the cargo drone via a cable section.

[0030] It can also be provided that the clamp can be suspended in a rail, just as conventional clamp designs on chairlifts are guided in rails in the station.

[0031] In one embodiment, the cargo drone has at least one, preferably four, six, eight, or sixteen, rotor(s), wherein the at least one rotor is preferably attachable to at least one boom, and wherein particularly preferably exactly one and/or exactly two rotors are attachable to each boom. The cargo drone can thus be designed as a multicopter.

[0032] Various shapes of the booms are conceivable, with all rotors preferably being arranged on an imaginary circle. In particular, a plus configuration is conceivable, in which one rotor is arranged at the front in the forward flight direction. A cross configuration is also conceivable, in which two rotors are arranged at the front in the forward flight direction.

[0033] It can be provided that two propellers are mounted on a boom and can be operated coaxially in opposite directions.

[0034] The cargo drone may have at least one electric motor, wherein the at least one electric motor can be supplied with electrical energy by at least one rechargeable battery. Provision may be made for several electric motors to be supplied with electrical energy by one rechargeable battery. However, provision may also be made for each electric motor to be assigned a rechargeable battery.

[0035] It is particularly advantageous that one rotor or two coaxial rotors can be driven by an electric motor. The cargo drone can thus be controlled by varying the speed of the electric motors without a transmission gear or tilting the rotors.

[0036] In one embodiment, it is provided that the cargo drone has at least one sensor.

[0037] The cargo drone may have at least one position sensor, in particular at least one pressure sensor. This can be used, for example, to determine the altitude of the cargo drone.

[0038] The cargo drone may have at least one motion sensor, in particular at least one gyro sensor and/or acceleration sensor. A gyro sensor can be used to determine the rotation of the cargo drone. An acceleration sensor can be used to determine the acceleration of a drone.

[0039] The cargo drone can have at least one environmental sensor, in particular at least one camera, at least one LIDAR system and/or at least one RADAR system.

This allows you to avoid obstacles such as trees, rocks, masts or the ground.

[0040] In one embodiment, the cargo drone has a control unit for controlling at least one electric motor, wherein the control unit is connectable to sensors. The control unit can process sensor signals and, using a control algorithm, control the motor speeds such that the cargo drone flies in a stable, stationary position in the air, flies in a moving position, and/or performs another maneuver.

[0041] The passenger drone may have at least one communication unit, preferably wherein the communication unit has an antenna for communication, wherein electromagnetic signals - from a satellite, in particular a navigation satellite, and/or - to and from a mobile and/or stationary transmitting unit, in particular via a mobile radio network, can be sent and/or received.

[0042] Electromagnetic signals from a satellite, in particular a navigation satellite, can be used to determine the position of the passenger drone by means of a navigation satellite system, such as GPS.

[0043] Likewise, electromagnetic signals can be received to and from a mobile transmitter unit. If a winter sports enthusiast wears a mobile transmitter unit, such as a smartphone or smartwatch, they can give instructions to the passenger drone. Likewise, the passenger drone can transmit its location or its free/occupied status to a winter sports enthusiast, for example.

[0044] Electromagnetic signals can also be transmitted via a stationary transmitter unit. Voice messages and/or data, such as maps and/or control instructions, can be sent via a mobile network.

[0045] In one embodiment, a first communication unit is provided in the cargo drone, and a second communication unit is provided on the suspension and/or on at least one chair. This allows at least one electrical signal to be sent between the first communication unit and the second communication unit, for example, to send status messages from the cargo drone to the winter sports enthusiast or control instructions from the winter sports enthusiast to the cargo drone. The first and/or second communication unit can also be configured to communicate with third parties.

[0046] In one embodiment, an operator unit is arranged on at least one chair and/or on the suspension system, wherein the operator unit has a display and/or actuating elements, preferably wherein the cargo drone is controllable by means of the operator unit. In particular, the operator unit can communicate with the control unit via the first and second communication units.

[0047] Furthermore, an intercom system can be arranged on at least one chair and/or on the suspension system. This allows a winter sports enthusiast to communicate with a third party, which third party can be, in particular, a base station and/or a winter sports enthusiast in another passenger drone.

[0048] Communication can take place via the communication unit, in particular the first communication unit. For this purpose, signals can be sent between the communication unit and the operator unit, preferably wirelessly. This allows, for example, the winter sports enthusiast to control the cargo drone.

[0049] As mentioned at the outset, a method according to the invention provides for the transport of winter sports enthusiasts, in particular with strapped-on winter sports equipment, with at least one described passenger drone.

[0050] An embodiment of the method according to the invention comprises at least one of the following method steps:

- Accommodates at least one winter sports enthusiast in at least one chair,

- Transport of at least one winter sports enthusiast from at least one first base station to a disembarkation point, preferably higher than the at least one first base station, by, preferably autonomous, flying of the passenger drone,

- Drop off at least one winter sports enthusiast at an exit point,

- Return of the passenger drone to the at least one first base station or to at least one second base station.

[0051] A charging station for charging the passenger drone, in particular the batteries, can be provided in the base station.

[0052] At least one winter sports enthusiast can be accommodated in the at least one first base station in the at least one chair. It can be provided that the first base station can only be accessed with a ski pass, for example, using an access system.

[0053] It may be provided that, when picking up at least one winter sports enthusiast, the suspension system with the at least one seat is separated from the cargo drone, and the cargo drone is connected to the suspension system only before the at least one winter sports enthusiast is transported. Thus, the winter sports enthusiast can be picked up by a cargo drone and seated beforehand.

[0054] The following method steps can be provided: - Picking up at least one winter sports enthusiast at at least one valley station, with the suspension device being attached to the cable of a chairlift; - Transporting the at least one winter sports enthusiast to at least one first base station, preferably located higher than the valley station, by the chairlift; - Decoupling the suspension device from the cable of the chairlift; - Attaching the suspension device to the cargo drone. Thus, only the final transport section, preferably in rough terrain, can be accomplished with a cargo drone.

[0055] The suspension system with the at least one chair can be provided in the at least one first base station in a suspended position and/or standing on the ground to accommodate at least one winter sports enthusiast. If the suspension system is provided in a suspended position, it can be provided that the suspension system is suspended in a stand with the fastening device. If the suspension system is provided in a standing position, it can be provided that the suspension system is placed on the parking device.

[0056] It can be provided that the passenger drone remains within a predefined flight corridor when transporting the at least one winter sports enthusiast and/or during the return. A navigation satellite system, in particular GPS, of the passenger drone can be used for this purpose. This prevents the passenger drone from straying into dangerous areas, such as areas with air traffic.

[0057] In one embodiment, it is provided that the passenger drone, when transporting the at least one winter sports enthusiast and/or when returning, at least in sections

- flies autonomously, and/or

- is controlled from a base station, and/or

- is controlled by at least one winter sports enthusiast.

[0058] Preferably, the passenger drone flies autonomously, for example, based on a map. For example, the passenger drone can be controlled by the winter sports enthusiast before disembarkation and/or in emergencies. Likewise, in emergencies, the passenger drone can be controlled from the base station.

[0059] When dropping off at least one winter sports enthusiast at the exit point, it can be registered whether the drop-off of at least one winter sports enthusiast has taken place. The registration can preferably

- automatically, in particular by measuring a weight recording device, and/or - by manual indication of at least one winter sports enthusiast, and/or - by remote indication from the base station.

[0060] The weight detection device can measure the decreasing load weight of the passenger drone and conclude from this that the release of at least one winter sports enthusiast has taken place.

[0061] The manual indication of the at least one winter sports enthusiast can be carried out via the actuating device and/or a mobile transmitting unit, in particular via the first communication unit.

[0062] The remote indication from the base station can be carried out via the communication unit.

[0063] In one embodiment, an autonomous return of the passenger drone to the at least one first base station or to at least one second base station can be initiated by registering the drop-off of the at least one winter sports enthusiast. For example, the passenger drone can return automatically after a jump by the at least one winter sports enthusiast.

[0064] It can be provided that the passenger drone follows the at least one winter sports enthusiast before or during the return. The passenger drone can, for example, take a video of the winter sports enthusiast. Preferably, it is provided that the passenger drone sends a warning signal to the base station in the event of an emergency. An emergency can be, for example, an avalanche and/or a fall of the winter sports enthusiast. An emergency can be detected automatically, in particular by means of artificial intelligence, and/or via the camera on the passenger drone from the base station.

[0065] Particularly preferably, the at least one winter sports enthusiast can summon the passenger drone away from the at least one base station, preferably using a mobile transmission unit. This can then result in a recording of the at least one winter sports enthusiast away from the at least one base station. This can also be used in an emergency, for example, if the winter sports enthusiast can no longer continue skiing, either due to an injury or because the downhill route is blocked by a cliff.

[0066] This function can also be used on a planned basis, for example, when a descent route is not fully navigable, for example, because a cliff blocks the way. This allows the upper part of the descent route to be navigated, followed by a planned re-ascent with the passenger drone.

[0067] Of course, the passenger drone, like a chairlift, can also be used in the summer. Likewise, the passenger drone can be used for non-sporting purposes.

[0068] For example, the passenger drone can be used as a rescue drone. A person in need of rescue can be picked up by the passenger drone. If the drone is designed as a two-seater, a first responder can be transported to the person in need of rescue by the passenger drone. It can also be provided that, instead of a seat for the second person, a mount for an akia or stretcher is provided.

[0069] This eliminates the need for first responders to ascend to the scene of the accident themselves, saving time and minimizing the risk to the injured person. Likewise, the risk to first responders is minimized, as they do not have to ascend into potentially dangerous areas.

[0070] The advantage of using a passenger drone over a helicopter is that passenger drones can fly close to the ground even in low visibility conditions, even in rugged terrain that is dangerous for helicopters. Thanks to their autonomous flight function, passenger drones always find their way back to their base station.

with two base stations, and

[0079] Fig. 8 Method for transporting a winter sports enthusiast with a passenger drone in combination with a chairlift.

[0080] Fig. 1 and Fig. 2 show a passenger drone 1 for transporting winter sports enthusiasts with strapped-on winter sports equipment, with a cargo drone 2, wherein a suspension device 3 is attached, preferably detachably, to the cargo drone 2. A chair 4 for at least one winter sports enthusiast is attached to the suspension device 3.

[0081] Fig. 1 shows a front view and Fig. 2 a side view of the passenger drone 1. In Fig. 2, a winter sports enthusiast 45 is also shown sitting on the chair 4 with strapped-on winter sports equipment 46, here in the form of skis.

[0082] In the embodiment, the chair 4 is designed as a double chair for two winter sports enthusiasts.

[0083] A safety bar 5 is arranged on at least one chair 4, and a footrest 6 is also arranged on the safety bar 5. A winter sports enthusiast 45 can rest his foot, or possibly his winter sports equipment 46, on the footrest 6. The safety bar 5 is pivotally mounted so that it can be pivoted from a closed position, as in Fig. 1 and Fig. 2, into an open position. In an open position, a winter sports enthusiast 45 can get in and out.

[0084] The suspension 3 has a curved shape, at least in sections. The curved shape of the suspension 4 is typical for suspensions of chairlifts, where this shape is necessary due to the supports. The suspension 3 and the chair 4 can be shaped like those of a conventional chairlift.

[0085] The chair 4 has a chair frame 38, which is connected to the suspension 3. In the lower area of the chair frame 38, a seat 40 and a backrest 39 are arranged, which form the actual seat support for the winter sports enthusiast 45.

[0086] The seat 4 and/or the suspension 3 can be made at least partially, preferably largely, of fiber-reinforced plastic, in particular of carbon fiber-reinforced plastic. This keeps the weight of the passenger drone 1 low.

[0087] A parking device 7 is arranged on the chair 4, wherein the parking device 7 extends into an area below the at least one chair 4 and the suspension 3. The parking device 7 has at least one skid 8. This allows the passenger drone 1 to be moved in the snow. It can also be provided that the parking device 7 has at least one wheel, although this is not shown in the figures. The parking device 7 is attached here to the chair rod 38.

[0088] The cargo drone 2 has a connecting part 10, with the connecting part 10 being able to attach the suspension 3 to the cargo drone 2. The suspension 3 has, at the end opposite the at least one chair 4, a fastening device 15 for connecting

connection with the cargo drone 2. Further details on the attachment of the hanger 3 to the cargo drone 2 can be seen in Fig. 4a, b and Fig. 5.

[0089] Figure 3 shows a cargo drone 3 with devices inside the cargo drone 3 in a sectional view. The cargo drone 2 has a base body 41 with a housing, four outriggers 20 extending outward from the base body, and four rotors 19 each attached to the outer ends of the outriggers.

[0090] The axes of the rotors 19 are located on an imaginary circle (also in Fig. 1 and Fig. 2). The cargo drone 2 is designed here in a plus configuration. This means that with four rotors 19, one rotor 19 is arranged at the front in the forward flight direction, two rotors 19 are arranged centrally at the sides, and one rotor 19 is arranged at the rear.

[0091] Inside, the cargo drone 2 has one electric motor 21 per rotor 19, wherein the electric motors 21 are supplied with electrical energy by at least one accumulator 22. An electric motor 21 associated with a rotor 19 is arranged coaxially with the rotor 19. Thus, no transmission is necessary, and the rotor 19 can be driven directly by the electric motor 21.

[0092] The cargo drone 2 is controllable by means of a control unit 27 for controlling at least one electric motor 21. The control unit 27 is connectable to sensors 23.

[0093] Based on the input of the sensors 23, the speed of the electric motors 21 can be adjusted for control.

[0094] The sensors 23 of the cargo drone 2 comprise at least one position sensor 24, in particular at least one pressure sensor, with which the altitude can be determined.

[0095] The sensors 23 of the cargo drone 2 also include a motion sensor 25, in particular at least one gyro sensor and an acceleration sensor, with which rotation and acceleration can be measured. A motion sensor can also be used for an inertial navigation system, with which the relative position of the cargo drone 2 can be determined.

[0096] The sensors 23 of the cargo drone 2 also include at least one environmental sensor 26, in particular at least one camera, at least one LIDAR system, and/or at least one RADAR system, with which the environment can be perceived. This allows, for example, obstacles to be detected.

[0097] The passenger drone 1 also has a communication unit 28, wherein the communication unit 28 has an antenna 29 for communication. Electromagnetic signals from a satellite, in particular a navigation satellite, and/or to and from a mobile and/or stationary transmitting unit, in particular via a mobile radio network, can be sent and received via the antenna 29. Using signals from a navigation satellite, the absolute position of the passenger drone 1 can be determined, for example, using GPS. Furthermore, communication can take place with a winter sports enthusiast 25 or a base station 32.

[0098] A first communication unit 281 is provided in the cargo drone 2. This can be seen in Fig. 3.

[0099] A second communication unit 282 is provided on at least one chair 4, as shown in Fig. 1. Here, the second communication unit 282 is mounted on the chair frame 38 at the head height of a winter sports enthusiast 45. An intercom 31 is also installed on the second communication unit 282, by means of which a winter sports enthusiast 45 can receive and send voice messages.

[00100] An operator unit 30 is also arranged on the chair frame 38, wherein the operator unit 30 has a display and/or actuating elements. The cargo drone 2 can be manually controlled by the winter sports enthusiast using the operator unit 30. The status of the cargo drone 2, for example, the speed, altitude, or position, can be displayed on the display. A map can also be shown.

[00101] Signals can be transmitted, preferably wirelessly, between the communication unit 28, preferably the first communication unit 281, and the operator unit 30. This allows, for example, the cargo drone 2 to be controlled by the winter sports enthusiast 45.

[00102] Figures 4a, 4b and 5 show the connection of the cargo drone 2 to the hanger 3, in particular different views of the connecting part 10 of the cargo drone 2 and the fastening device 15 on the hanger 3 for connecting the cargo drone 2 to the hanger 3.

[00103] Fig. 4a shows a front view of an exemplary embodiment. Here, the suspension device 3 can be attached to the cargo drone 2 via a cable section 12. The cable section can also be designed as a rod or tube with similar dimensions.

[00104] More precisely, the suspension device 3 can be attached to the cargo drone 2 via a clamp 16, wherein the clamp 16 is held in a closed position by a spring 17 and can be moved from a closed position to an open position by means of an actuating lever 18. In Fig. 4a, the clamp 16 is shown in the closed position.

[00105] Fig. 4b shows a side view of the embodiment in Fig. 4a, with the clamp 16 not shown. However, the cable section 12, which is attached to the connecting part 10, is clearly visible.

[00106] In Figures 4a and 4b, a weight detection device 14 is arranged between the cargo drone 2 and the suspension 3. Here, the weight detection device is arranged in the upper area of the connecting part 10. This can, for example, use strain gauges to measure the weight of the suspension 3 and the chair 4, including the load—that is, the winter sports enthusiasts. This can be used to determine whether and how many winter sports enthusiasts are sitting on the chair 4.

[00107] A joint 11 is attached to the suspension 3, in particular to the fastening device 15. The suspension 3 is thus pivotally mounted relative to the cargo drone 2, whereby the suspension 3 and the chair 4 are arranged essentially vertically even when the cargo drone 2 is tilted, i.e., when the cargo drone 2 is in forward flight. The joint 11 can be damped to prevent excessive swinging of the suspension 3 during flight. The joint 11 is designed here as a pivot bearing.

[00108] Fig. 5 shows an alternative embodiment of a connection of the cargo drone 2 to the hanger 5, in particular the connecting part 10 of the cargo drone 2 to the fastening device 15 on the hanger 3.

[00109] Here, the fastening device 15 is formed as a round or angular plug, which can be inserted into an opening in the connecting part 10 adapted to the plug and can snap into the opening.

[00110] Also shown here is a weight detection device 14, which is arranged here on the suspension device 3, in particular on the fastening device 15. As usual, this device can have strain gauges for determining the weight.

[00111] A joint 11 is arranged in the upper area of the connecting part, wherein the joint 11 is designed as a lockable ball joint. Because the ball joint is lockable, a deactivated cargo drone 2 can be held on the stationary suspension 3 with the chair 4 without tipping over.

[00112] It is intended to use the passenger drone 1 for the transport of winter sports enthusiasts 45, in particular with strapped-on winter sports equipment 46.

[00113] Figure 6 shows an embodiment of a method for transporting winter sports enthusiasts. It shows a mountainous area suitable for downhill skiing with winter sports equipment 46. In particular, a downhill route 43 is suitable for downhill skiing. Therefore, it is desirable for a winter sports enthusiast 45 to go to the beginning of the downhill route 43. This can be, for example, a summit.

[00114] For this purpose, the at least one winter sports enthusiast 45 is first accommodated in at least one chair 4. The winter sports equipment 46 is preferably at least partially strapped on.

[00115] The reception of at least one winter sports enthusiast in at least one chair 4 can take place in the at least one first base station 321.

[00116] The first base station 321 can be, for example, a mountain hut or a lift station. However, the first base station 321 can also simply be the location from which the winter sports enthusiast 45 takes off with the passenger drone 1.

[00117] When picking up at least one winter sports enthusiast 45, the suspension 3 with the at least one chair 4 can be separated from the cargo drone 2, and the cargo drone 2 can be connected to the suspension 3 only before the transport of the at least one winter sports enthusiast. For example, the chairs 4 can be stored at the base station 321 and picked up by the cargo drone 2 only after a winter sports enthusiast 45 has taken a seat.

[00118] The suspension system 3 with the at least one chair 4 can be provided in the at least one first base station 321 hanging and/or standing on the ground to accommodate at least one winter sports enthusiast.

[00119] In a next step, the at least one winter sports enthusiast 45 is transported from at least one first base station 321 to an exit point 33, preferably higher than the at least one first base station 321, by, preferably autonomous, flying of the passenger drone 1.

[00120] When transporting at least one winter sports enthusiast, the passenger drone 1 can fly autonomously, at least in sections, or be controlled from the base station 32 or be controlled by at least one winter sports enthusiast 45. In this case, the passenger drone 1 can remain within a predefined flight corridor 37 when transporting at least one winter sports enthusiast 45. The flight route 44 is therefore located within the flight corridor 37.

[00121] In a next step, the at least one winter sports enthusiast 45 is dropped off at the exit point 33. In other words, the at least one winter sports enthusiast 45 disembarks from the seat 4 of the passenger drone 1. Because the at least one winter sports enthusiast 45 is sitting in a seat 4 with the winter sports equipment 46 strapped on, disembarkation is made significantly easier, and strapping on the winter sports equipment 46 at the exit point 33 is no longer necessary.

[00122] The exit point 33 may be a point in exposed terrain, for example a summit, a summit ridge or a steep gully.

[00123] The exit point 33 is located at the beginning of the downhill route 43. After the winter sports enthusiast has exited / dropped off the winter sports enthusiast, the winter sports enthusiast 45 can enjoy the downhill run along the downhill route 43.

[00124] The passenger drone 1 can follow at least one winter sports enthusiast, preferably with the passenger drone 1 sending a warning signal to the base station 32 in the event of an emergency.

[00125] The at least one winter sports enthusiast can summon the passenger drone 1 away from the at least one base station 32, preferably using a mobile transmission unit. The at least one winter sports enthusiast can then be photographed away from the at least one base station 32, and the drone can then return to the valley or fly again to an exit point 33. This also allows partial travel on downhill routes that are not continuously accessible.

[00126] When the at least one winter sports enthusiast 45 is dropped off at the exit point 33, it can be registered whether the at least one winter sports enthusiast 45 has been dropped off. The registration can be carried out automatically, in particular by measuring a weight detection device 14, and/or by manual indication of the at least one winter sports enthusiast 45, and/or by remote indication from the base station 32.

[00127] In a next step, the passenger drone 1 can return to the at least one first base station 321. It is then available there for other winter sports enthusiasts 45. Likewise, the passenger drone 1 can wait for the winter sports enthusiast 45 who has just been transported to the exit point 33. As shown in Fig. 6, the first base station 321 can be located at the end of the departure route 43.

[00128] An autonomous return of the passenger drone 1 to the at least one first base station 321 or to at least one second base station 322 can be started by registering the drop-off of the at least one winter sports enthusiast 45.

[00129] Fig. 7 shows a further embodiment of a method for transporting at least one winter sports enthusiast 45, in particular with strapped-on winter sports equipment 46. Here, the flight corridor 37 is extended.

[00130] A first descent route 43 leads from a first exit point 33 to the first base station 321, as shown in Fig. 6. Furthermore, a winter sports enthusiast 45 can descend from the first exit point 33 via a second descent route 43 to a second base station 322. From the second base station 322, the winter sports enthusiast 45 can be transported to a second exit point 33, for example, on another peak. From there, a winter sports enthusiast 45 can descend again to the second base station 322 via a third descent route 43.

[00131] Like the first base station 321, the second base station 322 can be configured as a hut. However, it can also be merely a, possibly predefined, location where a winter sports enthusiast 45 is photographed by a passenger drone 1.

[00132] The departure from the second base station 322 to the first base station 311 is not possible in the embodiment of Fig. 7 because cliffs 42 block the path. Thus, the departure routes 43 to the second base station 322 are only accessible by a passenger drone 1 picking up the winter sports enthusiast 45 from the second base station 322.

[00133] As can be seen from Fig. 7, a kind of flexible, easily changeable winter sports area can be created through the use of passenger drones 1. The downhill routes, exit points, and flight paths can be changed daily depending on the avalanche and weather conditions.

[00134] Fig. 8 shows the connection to a traditional ski area with a chairlift. Here, at least one winter sports enthusiast 45 can be picked up at a valley station 34. The suspension device 3 can initially be attached to the cable 36 of a chairlift 35. The chairlift 35 transports the at least one winter sports enthusiast 45 to at least one first base station 321, preferably located higher than the valley station 34.

[00135] In the first base station 321, which is designed here as a lift station, the suspension device 3 is decoupled from the cable 36 of the chairlift 35. This can be accomplished using a clamp 16, as with conventional chairlifts 35. Instead of re-coupling the suspension device 3 into the cable 36 of the chairlift after one circuit, the suspension device 3 is coupled into the connecting part 10 of a cargo drone 2. Preferably, the connecting part 10 has a cable section 12, as in Figs. 4a and 4b. The passenger drone 1 can now transport the at least one winter sports enthusiast 45 to an exit point 33, as shown, for example, in Figs. 6 and 7.

[00136] This allows only the last part of the journey through rough, exposed terrain to be covered by the passenger drone 1, while the majority of the route is covered by chairlift. Thus, the passenger drone 1 is only used for short distances and can be recharged at the base station 321.
