Abstract

A remote-controlled, semi-autonomous or autonomous recovery apparatus includes a drive as well as a unit for launch and recovery of an autonomous underwater vehicle. The drive is dimensioned such that a large range, such as more than 5 nautical miles, is obtained.

First claim

The invention claimed is:

1. Autonomous system comprising an autonomous underwater vehicle and an autonomous recovery apparatus for the autonomous underwater vehicle, comprising:
a drive of autonomous recovery apparatus, wherein the drive is implemented as part of the autonomous recovery apparatus and is configured to transport the autonomous recovery apparatus together with the autonomous underwater vehicle across a range, wherein the range is a range of more than 5 nautical miles;
a unit for launch and recovery of the autonomous underwater vehicle, wherein the recovery apparatus is configured to be operated in an autonomous manner;
wherein the autonomous underwater vehicle is configured to be operated independent from the recovery apparatus;
wherein the autonomous recovery apparatus comprises a sensor system as well as a control unit, wherein the control unit is configured to perform semi-autonomous or autonomous control of the recovery apparatus based on data from the sensor system and wherein the control unit is configured to autonomously launch and/or recover the autonomous underwater vehicle; and
wherein the recovery apparatus comprises two hulls and a net arranged between the two hulls for receiving the autonomous underwater vehicle, wherein the net can be lowered from a non-lowered state of the net to a lowered state of the net where the net floats below the water surface such that the autonomous underwater vehicle can be launched and received in the lowered state and can be transported in the non-lowered state.

2. Autonomous system according to claim 1 , wherein the drive comprises a combustion engine for moving the recovery apparatus as well as a fuel tank having a holding capacity for the range.

3. Autonomous system according to claim 1 , wherein the drive comprises an electric motor for moving the recovery apparatus.

4. Autonomous system according to claim 3 , wherein the recovery apparatus comprises a battery having a capacity for the range and/or a generator in combination with a fuel tank having a holding capacity for the range.

5. Autonomous system according to claim 3 , wherein the recovery apparatus comprises an energy generator.

6. Autonomous system according to claim 1 , wherein the recovery apparatus comprises a controller for controlling an oar, at least a rotatable drive pod and/or in the form of two juxtaposed ship propellers.

7. Autonomous system according to claim 1 , wherein the control unit is configured to dock the recovery apparatus autonomously at land and/or at a pier and/or at a mother ship.

8. Autonomous system according to claim 1 , wherein the recovery apparatus comprises a GPS receiver or GNSS receiver as sensor system.

9. Autonomous system according to claim 1 , wherein the recovery apparatus comprises a repeater that is configured to forward navigation signals and/or control signals to the autonomous underwater vehicle.

10. Autonomous system according to claim 1 , wherein the recovery apparatus is configured to supply the autonomous underwater vehicle with electric energy for charging the autonomous underwater vehicle.

11. Autonomous system according to claim 1 , wherein the recovery apparatus comprises a position determiner and/or a transmitter arranged underwater and a receiver arranged underwater and/or a hydrophone arranged underwater such that the position of the autonomous underwater vehicle can be determined during a diving operation.

12. Autonomous system according to claim 1 , wherein the recovery apparatus comprises a controller for controlling a rotatable drive pod.

13. Autonomous system according to claim 1 , wherein the recovery apparatus comprises a controller for controlling two juxtaposed ship propellers.
