Abstract

Methods and apparatus for hull attachment for submersible vehicles are disclosed. In one embodiment, a submersible apparatus includes a hull having an elongated channel, a sliding member moveably disposed in the channel, and a mounting assembly attached to the sliding member. The mounting assembly includes an engagement member selectively engageable between a first position wherein the mounting assembly is moveable along the channel, and a second position wherein the mounting assembly is secured in a fixed position along the channel. The apparatus advantageously permits a wide variety of equipment or devices (e.g. tow point assemblies, wing assemblies, tail assemblies, propulsion units, illumination devices, imaging devices, instrumentation, sensors, etc.) to be adjustably attached to the hull, and provides improved adjustability, maintainability, integrity, reliability, and overall improved mission performance.

Claims

1. A submersible vehicle adapted to operate within a fluid medium, comprising:

an enclosed, substantially fluid-tight hull surrounding an interior region and having an external surface including a non-planar portion, the hull further having a channel formed at least partially within the non-planar portion the channel being at least partially disposed below an upper surface of the fluid medium during operation of the submersible vehicle within the fluid medium;

a sliding member disposed within the channel and moveable along at least a portion of the channel; and

a mounting assembly attached to the sliding member and including an engagement member coupled to the sliding member, the engagement member being moveable between a first position wherein the sliding member is moveable within the channel and a second position wherein the sliding member is secured in a fixed position within the channel.

2. The vehicle of claim 1 wherein the channel is integrally formed within the external surface of the hull.

3. The vehicle of claim 1 wherein the channel comprises a longitudinal channel.

4. The vehicle of claim 1 wherein the channel comprises an at least partially circumferential channel.

5. The vehicle of claim 1 wherein the sliding member includes an engagement surface that engages a locking surface of the channel.

6. The vehicle of claim 1 wherein the engagement member comprises a threaded member.

7. The vehicle of claim 1, further comprising a tow point assembly attached to the mounting assembly.

8. The vehicle of claim 1, further comprising a wing attached to the mounting assembly.

9. The vehicle of claim 1, further comprising a tail assembly attached to the mounting assembly.

10. The vehicle of claim 1, further comprising a propulsion unit attached to the mounting assembly.

11. The vehicle of claim 1, further comprising a support attached to the channel and projecting forwardly of the hull.

12. The vehicle of claim 1, further comprising a forward payload assembly including a support attached to the channel and projecting forwardly of the hull, the forward payload assembly including an imaging device.

13. A submersible vehicle adapted to operate within a fluid medium, comprising:

an enclosed, substantially watertight hull surrounding an interior region and having a non-planar external surface configured to form an elongated channel at least partially within the non-planar external surface, the channel being at least partially disposed below an upper surface of the fluid medium during operation of the submersible vehicle within the fluid medium;

a sliding member at least partially disposed within the channel and moveable along at least a portion of the channel, and

a mounting assembly attached to the sliding member and including an engagement member coupled to the sliding member, the engagement member being selectively engageable between a first position wherein the mounting assembly is moveable along the channel, and a second position wherein the mounting assembly is secured in a fixed position along the channel.

14. The apparatus of claim 13 wherein the hull comprises a substantially enclosed hull of a submersible vehicle.

15. The apparatus of claim 13 wherein the channel is integrally formed within the hull.

16. The apparatus of claim 13 wherein the hull extends along a longitudinal direction and the channel comprises a longitudinally-extending channel.

17. The appatatus of claim 13 wherein the non-planar external surface has a circumferential portion and the channel comptises an at least partially circumferentially-extending channel.

18. The apparatus of claim 13, further comprosomg a tow point assembly attached to the mounting assembly.

19. The apparatus of claim 13, further comprising a propulsion unit attached to the mounting assembly.

20. The apparatus of claim 13, further comprising a payload assembly including a support attached to the channel and projecting forwardly of the hull, the payload assembly including an imaging device.
