Abstract

In one possible embodiment, an amphibious unmanned aerial vehicle is provided, which includes a fuselage comprised of a buoyant material. Separators within the fuselage form separate compartments within the fuselage. Mounts associated with the compartments for securing waterproof aircraft components within the fuselage. The compartments each have drainage openings in the fuselage extending from the interior of the fuselage to the exterior of the fuselage.

Claims

1. An amphibious unmanned aerial vehicle comprising:

a) a fuselage comprised of a buoyant material walls;

b) separators within the fuselage forming separate compartments within the fuselage;

c) mounts associated with the compartments for securing waterproof aircraft components within the fuselage; and

d) the compartments each having drainage openings in the fuselage extending from the interior of the fuselage to the exterior of the fuselage.

2. The amphibious unmanned aerial vehicle of claim 1, wherein the drainage openings in at least some of the compartments comprise weep holes through a wall of the fuselage.

3. The amphibious unmanned aerial vehicle of claim 1, wherein at least one of the compartments comprises a drainage channel at a bottom thereof, and wherein the drainage channel comprises at least one drainage opening associated therewith.

4. The amphibious unmanned aerial vehicle of claim 3, wherein the at least one drainage opening comprises a weep hole.

5. The amphibious unmanned aerial vehicle of claim 3, wherein the at least one drainage opening comprises a plurality of weep holes.

6. The amphibious unmanned aerial vehicle of claim 1, wherein the separate compartments comprise:

a) a forward battery compartment;

b) a central payload compartment; and

c) a rear avionics compartment.

7. The amphibious unmanned aerial vehicle of claim 1, further comprising at least one skid pad on a bottom of the fuselage.

8. The amphibious unmanned aerial vehicle of claim 1 further comprising drainage openings extending through the separators within the fuselage.

9. The amphibious unmanned aerial vehicle of claim 1 further comprising securing mechanisms associated with the compartments to secure the waterproof aircraft components in the compartments.

10. The amphibious unmanned aerial vehicle of claim 1, wherein at least some of the mounts within the compartments comprise integrated connectors for electrically connecting a corresponding aircraft component upon mounting of the corresponding aircraft component within a respective compartment.

11. The amphibious unmanned aerial vehicle of claim 1, wherein the compartments comprise a battery compartment comprising a surface mount connector flush with a mounting surface of the mounts within the battery compartment.

12. The amphibious unmanned aerial vehicle of claim 1, wherein the compartments comprise a payload compartment comprising a surface mount connector flush with a mounting surface of the mounts within the payload compartment.

13. The amphibious unmanned aerial vehicle of claim 1, wherein the compartments comprise a payload compartment comprising an open bottom.

14. The amphibious unmanned aerial vehicle of claim 13, wherein there is substantially no fuselage wall below the payload compartment.

15. The amphibious unmanned aerial vehicle of claim 1, wherein the compartments comprise an avionics compartment comprising a heat sink opening.

16. An amphibious unmanned aerial vehicle comprising:

a) a fuselage constructed of a buoyant material;

b) separators within the fuselage forming separate battery, payload, and avionics compartments within the fuselage;

c) mounts associated with the compartments for securing a battery, a payload, and avionics within the fuselage; and

d) drainage openings extending through the wall of fuselage to connect the compartments with the exterior of the unmanned aerial vehicle.

17. The amphibious unmanned aerial vehicle of claim 16, wherein the battery compartment further comprises at least one drainage channel.

18. The amphibious unmanned aerial vehicle of claim 17, wherein the at least one drainage channel comprises at least one of the drainage openings therein.

19. The amphibious unmanned aerial vehicle of claim 18, wherein the at least one of the drainage openings comprises a plurality of weep holes.

20. The amphibious unmanned aerial vehicle of claim 16, wherein the avionics compartment further comprises at least one drainage channel.

21. The amphibious unmanned aerial vehicle of claim 20, wherein the at least one drainage channel comprises at least one of the drainage openings therein.

22. The amphibious unmanned aerial vehicle of claim 21, wherein the at least one of the drainage openings comprises a plurality of weep holes.

23. An amphibious unmanned aerial vehicle comprising:

a) a fuselage constructed of a buoyant material;

b) separators within the fuselage forming separate battery, payload, and avionics compartments within the fuselage, the compartments comprising;
