Abstract

An external payload module or body that is mechanically attached to the exterior of a standard production AUV. The module expands the applications for which the AUV can be utilized and/or enhances an existing application(s), enabling current single or limited use AUV's to have multi-mission capability or enhancing existing capability without requiring complete redesign of the AUV. This approach capitalizes on the advantages of high-volume small AUV production to maintain low manufacturing and handling costs, while enabling greatly improved AUV mission flexibility.

First claim

The invention claimed is:

1. A system comprising:
an autonomous underwater vehicle that includes a front end, a rear end, and a propulsion mechanism;
an external payload module that is detachably mechanically connected to the autonomous underwater vehicle, the external payload module includes at least one payload system that is configured to enhance or expand the capability of the autonomous underwater vehicle, and one or more steerable control surfaces; and the external payload module does not include a propulsion mechanism; and
the external payload module includes a rear mounting section that is formed as a cylindrical sleeve that receives and surrounds the front end of the autonomous underwater vehicle.

2. The system of claim 1 , wherein the external payload module is detachably mechanically attached to the front end of the autonomous underwater vehicle.

3. The system of claim 1 , further comprising at least one I/O connection between the external payload module and the autonomous underwater vehicle.

4. The system of claim 1 , further comprising at least one power connection between the external payload module and the autonomous underwater vehicle.

5. A system comprising:
an autonomous underwater vehicle that includes a front end, a rear end, and a propulsion mechanism;
an external payload module that is detachably mechanically connected to the autonomous underwater vehicle, the external payload module includes at least one payload system that is configured to enhance or expand the capability of the autonomous underwater vehicle, and one or more steerable control surfaces; and the external payload module does not include a propulsion mechanism;
the external payload module includes a rear mounting section that is mechanically attached to the front end of the autonomous underwater vehicle, and a forward payload section that is located at least partially forward of the front end, and the one or more steerable control surfaces are located forward of the rear mounting section; and
the external payload module has a longitudinal axis that is collinear to a longitudinal axis of the autonomous underwater vehicle.

6. The system of claim 1 , wherein the at least one payload system comprises one or more of a sensor, a data processor that provides data processing capability, a power supply, communication equipment for transmitting and/or receiving signals, ordinance, a camera, a light, sonar, oceanographic instrumentation, a release mechanism for a buoy, surveillance equipment, an antenna.

7. A payload module that is mechanically connectable to an autonomous underwater vehicle that includes a front end, a rear end, and a propulsion mechanism, comprising:
at least one payload system that is configured to enhance or expand the capability of the autonomous underwater vehicle when the payload module is connected thereof, and one or more steerable control surfaces; and the payload module does not include a propulsion mechanism; and
the payload module includes a rear mounting section that is formed as a cylindrical sleeve that can receive and surround the front end of the autonomous underwater vehicle.

8. The payload module of claim 7 , wherein the payload module is configured to be detachably mechanically attached to the front end of the autonomous underwater vehicle.

9. The payload module of claim 7 , further comprising at least one I/O connection for connection to the autonomous underwater vehicle.

10. The payload module of claim 7 , further comprising at least one power connection for connection to the autonomous underwater vehicle.

11. A payload module that is mechanically connectable to an autonomous underwater vehicle that includes a front end, a rear end, and a propulsion mechanism, comprising:
at least one payload system that is configured to enhance or expand the capability of the autonomous underwater vehicle when the payload module is connected thereof, and one or more steerable control surfaces; and the payload module does not include a propulsion mechanism;
the payload module includes a rear mounting section that is mechanically attachable to the front end of the autonomous underwater vehicle, and a forward payload section, and the one or more steerable control surfaces are located forward of the rear mounting section; and
the payload module has a longitudinal axis that, when the payload module is connected to the autonomous underwater vehicle, is collinear to a longitudinal axis of the autonomous underwater vehicle.

12. The payload module of claim 7 , wherein the at least one payload system comprises one or more of a sensor, a data processor that provides data processing capability, a power supply, communication equipment for transmitting and/or receiving signals, ordinance, a camera, a light, sonar, oceanographic instrumentation, a release mechanism for a buoy, surveillance equipment, an antenna.

13. A method of expanding the capability of an autonomous underwater vehicle that includes a front end, a rear end, and a propulsion mechanism, comprising:
detachably mechanically connecting a first external payload module to the autonomous underwater vehicle using a rear mounting section of the first external payload module that is formed as a cylindrical sleeve that receives and surrounds the front end of the autonomous underwater vehicle; the first external payload module includes at least one payload system that is configured to enhance or expand the capability of the autonomous underwater vehicle, and one or more steerable control surfaces; and the first external payload module does not include a propulsion mechanism.

14. The method of claim 13 , further comprising detaching the first external payload module from the autonomous underwater vehicle and detachably mechanically connected a second external payload module to the autonomous underwater vehicle; the second external payload module includes at least one payload system that is configured to enhance or expand the capability of the autonomous underwater vehicle, and one or more steerable control surfaces; and the second external payload module does not include a propulsion mechanism.

15. The method of claim 13 , wherein the at least one payload system comprises one or more of a sensor, a data processor that provides data processing capability, a power supply, communication equipment for transmitting and/or receiving signals, ordinance, a camera, a light, sonar, oceanographic instrumentation, a release mechanism for a buoy, surveillance equipment, an antenna.
