Abstract

The present disclosure provides various embodiments of a multicopter-assisted launch and retrieval system generally including: (1) a multi-rotor modular multicopter attachable to (and detachable from) a fixed-wing aircraft to facilitate launch of the fixed-wing aircraft into wing-borne flight; (2) a storage and launch system usable to store the modular multicopter and to facilitate launch of the fixed-wing aircraft into wing-borne flight; and (3) an anchor system usable (along with the multicopter and a flexible capture member) to retrieve the fixed-wing aircraft from wing-borne flight.

First claim

The invention claimed is:

1. A multicopter storage system comprising:
a container including a top portion and a bottom portion positionable relative to one another to form an interior container cavity;
a tray operable in a storage position and a launch position, wherein in the storage position the tray fits within the interior container cavity and is configured to receive a first landing gear module of a multicopter, and wherein in the launch position the tray is configured to support the multicopter when the multicopter is assembled;
a rotor arm module and second landing gear module storage device that fits within the interior container cavity and to which a rotor arm module and a second landing gear module of the multicopter are attachable; and
a hub module storage device that fits within the interior container cavity and includes a hub module engager shaped to engage a hub module of the multicopter.

2. The multicopter storage system of claim 1 , wherein the rotor arm module and second landing gear module storage device defines a channel sized to slidably receive the rotor arm module.

3. The multicopter storage system of claim 2 , wherein the rotor arm module and second landing gear module storage device includes a rotor arm module lock device movable between a locked position in which part of the rotor arm module lock device extends into the channel to prevent the rotor arm module from exiting the channel and an unlocked position in which the rotor arm module lock device does not prevent the rotor arm module from exiting the channel.

4. The multicopter storage system of claim 3 , wherein the rotor arm module and second landing gear module storage device includes a biasing element that biases the rotor arm module lock device to the locked position.

5. The multicopter storage system of claim 1 , wherein the rotor arm module and second landing gear module storage device is mountable to the tray.

6. The multicopter storage system of claim 5 , wherein one of the tray and the rotor arm module and second landing gear module storage device includes a storage device lock and the other of the tray and the rotor arm module and second landing gear module storage device includes a storage device lock engager.

7. The multicopter storage system of claim 6 , wherein while the rotor arm module and second landing gear module storage device is mounted to the tray, the storage device lock is engageable to the storage device lock engager to lock the rotor arm module and second landing gear module storage device to the tray.

8. The multicopter storage system of claim 7 , wherein the storage device lock is movable from an unlocked position to a lock position to engage the storage device lock engager when the rotor arm module and second landing gear module storage device is mounted to the tray.

9. The multicopter storage system of claim 1 , wherein the tray includes a first landing gear module retainer sized and shaped to receive and hold the first landing gear module.

10. The multicopter storage system of claim 1 , wherein the rotor arm module and second landing gear module storage device include two surfaces that at least partially define a cavity sized to receive the second landing gear module, wherein the two surfaces are oriented to contact and retain the second landing gear module when received in the cavity.

11. The multicopter storage system of claim 1 , wherein the rotor arm module and second landing gear module storage device defines a storage channel sized to slidably receive the rotor arm module and includes a rotor arm module lock device that is movable between a locked position in which part of the rotor arm module lock device extends into the channel to prevent the rotor arm module from exiting the channel and an unlocked position in which the rotor arm module lock device does not prevent the rotor arm module from exiting the channel,
wherein the rotor arm module and second landing gear module storage device is mountable to the tray,
wherein one of the tray and the rotor arm module and second landing gear module storage device includes a storage device lock and the other of the tray and the rotor arm module and second landing gear module storage device includes a storage device lock engager,
wherein when the rotor arm module and second landing gear module storage device is mounted to the tray, the storage device lock is movable from an unlocked position to a lock position to engage the storage device lock engager to lock the rotor arm module and second landing gear module storage device to the tray.

12. A method for storing a multicopter in a container that includes a top portion and a bottom portion positionable relative to one another to form an interior container cavity, the method comprising:
attaching a first landing gear module of the multicopter to a tray, wherein the tray is operable in a storage position and a launch position, wherein in the storage position the tray fits within the interior container cavity and is configured to receive the first landing gear module, and wherein in the launch position the tray is configured to support the multicopter when the multicopter is assembled;
attaching a rotor arm module of the multicopter and a second landing gear module of the multicopter to a rotor arm module and second landing gear module storage device;
engaging a hub module storage device with a hub module of the multicopter; and positioning the top portion of the container relative to the bottom portion of the container to enclose the tray, the rotor arm module and second landing gear module storage device, and the hub module storage device in the interior container cavity.

13. The method of claim 12 , wherein attaching the rotor arm module to the rotor arm module and second landing gear module storage device includes sliding the rotor arm module into a storage channel defined by the second landing gear module storage device.

14. The method of claim 13 , which includes locking the rotor arm module in the storage channel with a locking device.

15. The method of claim 12 , which includes mounting the rotor arm module and second landing gear module storage device to the tray.

16. The method of claim 15 , which includes locking the rotor arm module and second landing gear module storage device to the tray.

17. The method of claim 16 , which includes locking the rotor arm module and second landing gear module storage device to the tray by engaging a storage device lock engager with a storage device lock while the rotor arm module and second landing gear module storage device is mounted to the tray.

18. The method of claim 17 , wherein locking the rotor arm module and second landing gear module storage device to the tray includes moving the storage device lock from an unlocked position to a lock position to engage the storage device lock engager while the rotor arm module and second landing gear module storage device is mounted to the tray.

19. The method of claim 12 , which includes attaching the second landing gear module to the rotor arm module and second landing gear module storage device by wedging the second landing gear module into a cavity partially formed by two surfaces so the surfaces contact and retain the second landing gear module.

20. The method of claim 12 , wherein attaching the rotor arm module to the rotor arm module and second landing gear module storage device includes sliding the rotor arm module into a storage channel defined by the second landing gear module storage device,
which includes locking the
