Abstract

A method for extinguishing fires includes the steps of loading an unmanned aerial vehicle (UAV) onto a transport aircraft and carrying the UAV to an altitude and location in proximity to a fire area. The UAV is launched from the transport aircraft and guided over the fire area using controllable fixed or deployable aerodynamic structures operably connected to the UAV. Once over the appropriate location, the UAV releases fire extinguishing or retardant material onto the fire or anticipated fire path.

Claims

1. A method for extinguishing fires, comprising:

loading an unmanned aerial vehicle (UAV) onto a transport aircraft;

carrying the UAV to an altitude and location in relation to a fire area using the transport aircraft;

launching the UAV from the transport aircraft;

guiding the UAV over the fire area; and

releasing fire extinguishing or retardant material from the UAV and onto the fire area.

2. The method of claim 1, wherein the fire area comprises a fire or an anticipated fire path.

3. The method of claim 1, wherein the loading step comprises the step of attaching the UAV to the exterior of the transport aircraft.

4. The method of claim 1, wherein the loading step comprises the step of placing the UAV into the transport aircraft.

5. The method of claim 1, wherein the guiding step comprises the step of communicating with and controlling flight of the UAV.

6. The method of claim 5, including the step of using a ground based communicator or the transport aircraft to control the UAV.

7. The method of claim 5, including the step of using UAV fixed or deployable aerodynamic structures for guiding and controlling the flight of the UAV.

8. The method of claim 7, wherein the fixed or deployable aerodynamic structures comprise at least one of a propulsion system, and controllable wing structures operably connected to the UAV.

9. The method of claim 8, wherein the propulsion system comprises a propellor or a jet.

10. The method of claim 5, wherein the guiding step includes the step of using navigation positioning data.

11. The method of claim 10, wherein the navigation positioning data comprises at least one of global positioning satellite (GPS) data, radio beacon data, very high frequency omni-directional range (VOR) data, and long range aid to navigation (LORAN) data.

12. The method of claim 5, wherein the guiding step includes the step of using wireless electromagnetic waves to remotely guide and control the flight of the UAV.

13. The method of claim 5, wherein the guiding step includes the step of using an optical sensor or camera to remotely guide the UAV.

14. The method of claim 1, including the step of importing data into a data processor for controlling the UAV.

15. The method of claim 14, wherein the importing data step includes the step of importing the data into a data processor of the transport vehicle or a ground based control system in communication with the UAV.

16. The method of claim 1, including the step of determining conditions relating to the fire.

17. The method of claim 16, wherein the determining conditions step includes the step of sensing weather conditions, including wind speed and direction.

18. The method of claim 1, including the step of determining conditions relating to the flight of the UAV.

19. The method of claim 18, wherein the determining conditions step includes the monitoring at least one of altitude, speed, and location of the UAV.

20. A method for extinguishing fires, comprising:

loading an unmanned aerial vehicle (UAV) onto a transport aircraft;

carrying the UAV to an altitude and location in relation to a fire area comprising a fire or an anticipated fire path using the transport aircraft;

launching the UAV from the transport aircraft;

guiding the UAV over the fire area using controllable fixed or deployable aerodynamic structures of the UAV;

determining conditions relating to the fire, including weather conditions;

monitoring flight conditions of the UAV, including altitude and location of the UAV; and

releasing fire extinguishing or retardant material from the UAV and onto the fire area.

21. The method of claim 20, wherein the loading step comprises the step of attaching the UAV to the exterior of the transport aircraft or placing the UAV into the transport aircraft.

22. The method of claim 20, wherein the guiding step comprises the step of communicating with and controlling flight of the UAV using a ground based communicator or the transport aircraft to control the UAV.

23. The method of claim 22, wherein the fixed or deployable aerodynamic structures comprise at least one of a propellor, a jet, and controllable wing structures operably connected to the UAV.

24. The method of claim 20, wherein the guiding step includes the step of using navigation positioning data, including at least one of global positioning satellite (GPS) data, radio beacon data, very high frequency omni-directional range (VOR) data, and long range aid to navigation (LORAN) data.

25. The method of claim 20, wherein the guiding step includes the step of using wireless electromagnetic waves or an optical sensor or camera to remotely guide and control the flight of the UAV.

26. The method of claim 20, including the step of importing data into a data processor of the transport vehicle or a ground based control system for controlling the UAV.
