Abstract

A system for performing an aerial display. The system includes a plurality of UAVs each including a propulsion device and a display payload, and the system includes a ground station system with a processor executing a fleet manager module and memory storing a different flight plan and a set of display controls for the UAVs. Then, wherein, during a display time period, the UAVs concurrently execute the flight plans through operation of the propulsion devices and operate the display payloads based on the display controls. The display payloads each include a lighting assembly and a light controller. The output light is one of a two or more colored light streams, and each of the display payloads further may include a light diffuser with the output light being directed onto a surface of the light diffuser. The light diffuser may include a light diffusing screen extending about the lighting assembly.

Claims

1. A system for providing an aerial display, comprising:

a plurality of UAVs each including a propulsion device and a display payload; and

a ground station system with a processor executing a fleet manager module and with memory storing a different flight plan and a set of display controls for each of the UAVs,

wherein, during a display time period, the UAVs concurrently execute the flight plans through operation of the propulsion devices and operate the display payloads based on the display controls.

2. The system of claim 1, wherein the display payloads each comprise a lighting assembly and a light controller and wherein the operating the display payloads includes using the light controller to selectively operate the lighting assembly to provide an output light.

3. The system of claim 2, wherein the output light is one of two or more colored light streams.

4. The system of claim 3, wherein each of the display payloads further comprises a light diffuser and the output light is directed onto a surface of the light diffuser.

5. The system of claim 4, wherein the light diffuser comprises a light diffusing screen extending about the lighting assembly and the surface is an inner surface of the light diffusing screen.

6. The system of claim 5, wherein each of the propulsion devices comprises a multicopter with a support structure upon which the display payload is mounted a distance apart from rotors of the multicopter.

7. The system of claim 3, wherein each of the propulsion devices includes a local control module and a communication mechanism for communicating with a neighboring one of the UAVs and wherein the light controller is operable based on a comparison of an identification of the neighboring one with a predefined neighbor in the flight plan.

8. The system of claim 1, wherein the flight plans are downloaded pre-flight to each of the propulsion devices, wherein during performance of an aerial display the propulsion devices independently and concurrently execute the downloaded flight plans, and wherein the display payloads of at least a subset of the UAVs are operated in two or more states based on progress of the UAVs along the downloaded flight plans.

9. The system of claim 1, wherein the flight plans are downloaded pre-flight to each of the propulsion devices, wherein during performance of an aerial display the propulsion devices independently and concurrently execute the downloaded flight plans, and wherein the fleet manager module communicates instructions to each of the UAVs to control operation of the display payloads during the performance of the aerial display.

10. A flight control method, comprising:

at a plurality of multicopters, receiving a flight plan unique to each of the multicopters;

concurrently operating the multicopters to execute the flight plans within an air space; and

during the operating of the multicopters, controlling a display payload supported by each of the multicopters to generate a visual display in the air space.

11. The method of claim 10, further including:

providing a communications channel between pairs of the multicopters;

with a first one of the multicopters detecting a second one of the multicopters in a predefined space proximal to the first one of the multicopters; and

operating the display payload of the first one of the multicopters in a new manner based on an identity of the second one of the multicopters.

12. The method of claim 10, wherein the display payload comprises a light source and a light diffuser positioned to receive output light from the light source and wherein the controlling the display payload comprises operating the light source to output one of the two or more colors of light onto the light diffuser.

13. The method of claim 12, wherein the light diffuser comprises a cylindrical light screen and wherein the light source is positioned within a hollow space defined by the cylindrical light screen.

14. The method of claim 10, further comprising controlling of the display payload with a ground control system communicating signals to a controller within the display payload, whereby the display payload of at least a number of the multicopters is varied a predefined flight plan for the number of the multicopters.

15. An apparatus for use in an aerial display, comprising:

a multicopter;

a lighting assembly supported by the multicopter; and

a light diffuser supported by the multicopter and positioned with a surface receiving output light from the lighting assembly,

wherein the lighting assembly includes a light controller and a light source operable to provide color the output light at least two different colors,

wherein the light controller operates to change the color during operation of the apparatus to provide the aerial display,

wherein the multicopter includes a communication mechanism for communicating with another of the multicopters and including logic determining an identity of the other multicopter, and

wherein the light controller operates to select the color based on the identity of the other multicopter.

16. The apparatus of claim 15, wherein the multicopter includes a local controller operating to move the multicopter along a flight plan associated with the aerial display and wherein the light assembly operates in at least a first and a second state at differing way points of the flight plan.

17. The apparatus of claim 15, wherein the first and second operating states are chosen from a plurality of states based on a present location of the multicopter, whereby the aerial display is animated.
