Abstract

An underwater vehicle includes a longitudinal body that defines a longitudinal axis and is rotatable about the longitudinal axis between a forward orientation and a sideways orientation, a wing attached to the longitudinal body that is moveable between a vertically extending wing orientation when the longitudinal body is in the forward orientation and a horizontally extending wing orientation when the longitudinal body is in the sideways orientation, a propulsion system having a front propulsion device and a rear propulsion device that is arranged rearwardly along the longitudinal axis relative to the front propulsion device, and an after-propulsion system arranged at a rear end of the longitudinal body that provides thrust along the longitudinal axis. The secondary propulsion system provides thrust in a perpendicular direction relative to the longitudinal axis.

First claim

What is claimed is:

1. An underwater vehicle comprising:
a longitudinal body that defines a longitudinal axis and is rotatable about the longitudinal axis between a forward orientation and a sideways orientation;
a wing attached to the longitudinal body wherein the wing is moveable between a vertically extending wing orientation when the longitudinal body is in the forward orientation and a horizontally extending wing orientation when the longitudinal body is in the sideways orientation, wherein the wing includes a plurality of sensors arranged along an entire span of the wing;
a propulsion system having a front propulsion device and a rear propulsion device that is arranged rearwardly along the longitudinal axis relative to the front propulsion device, the propulsion system providing thrust in a perpendicular direction relative to the longitudinal axis; and
an after-propulsion system arranged at a rear end of the longitudinal body that provides thrust along the longitudinal axis.

2. The underwater vehicle according to claim 1 , wherein the longitudinal body includes a stern body, a bow body, and a hull body to which the stern body and the bow body are connectable.

3. The underwater vehicle according to claim 2 , wherein the wing is arranged on the hull body.

4. The underwater vehicle according to claim 3 , wherein the wing has a span that extends along at least most of a length of the hull body.

5. The underwater vehicle according to claim 2 , wherein the hull body contains at least one munition.

6. The underwater vehicle according to claim 1 , wherein the after-propulsion system includes a propeller and a plurality of stators.

7. The underwater vehicle according to claim 1 , wherein the propulsion system includes a plurality of thrusters.

8. The underwater vehicle according to claim 1 , wherein the longitudinal body includes at least one moveable mass that moves the longitudinal body between the first orientation and the second orientation and maintains a buoyancy of the longitudinal body.

9. The underwater vehicle according to claim 8 , wherein the at least one moveable mass is a driven cog wheel that is arranged along a perimeter of the longitudinal body.

10. The underwater vehicle according to claim 8 , wherein the longitudinal body includes a front moveable mass and a rear moveable mass that is arranged rearwardly relative to the front moveable mass.

11. The underwater vehicle according to claim 1 , wherein the plurality of sensors includes at least one of an acoustic sensor, optical sensor, or combination thereof.

12. The underwater vehicle according to claim 1 , wherein the plurality of sensors includes a first sensor arranged at an end of the wing and a second sensor arranged at an opposite end of the wing relative to the first sensor.

13. The underwater vehicle according to claim 1 , wherein the underwater vehicle is autonomous.

14. A method of forming the underwater vehicle according to claim 1 , the method comprising:
forming the longitudinal body to have a hull body that defines the longitudinal axis and is rotatable about the longitudinal axis between the forward orientation and the sideways orientation;
attaching a bow body and a stern body to opposite ends of the hull body;
attaching the wing to the hull body;
arranging the front propulsion device in the bow body; and
arranging the rear propulsion device in the stern body, wherein the front propulsion device and the rear propulsion device provide thrust in the perpendicular direction relative to the longitudinal axis; and
arranging the after propulsion system at a rear end of the longitudinal body.

15. The method of claim 14 , wherein forming the hull body further includes selecting the hull body from a plurality of hull bodies that each have at least one different characteristic, the at least one different characteristic including one of:
an effector;
a sensor;
a launcher;
a control system; or
any combination thereof.

16. The method according to claim 14 , wherein attaching the bow body and the stern body to opposite ends of the hull body further includes selecting the bow body and the stern body from a plurality of bow bodies and stern bodies that each have at least one different characteristic, the at least one different characteristic including one of a propeller, a thruster, a stator and any combination thereof.

17. The method according to claim 14 further comprising arranging a moveable mass in at least one of the bow body and the stern body that rotates the hull body and maintains a buoyancy of the underwater vehicle.

18. The method according to claim 14 further comprising:
forming the wing to have a span that extends along at least most of a length of the hull body;
arranging a first sensor at an end of the wing; and
arranging a second sensor at an opposite end of the wing relative to the first sensor.

19. An underwater vehicle comprising:
a longitudinal body that defines a longitudinal axis and is rotatable about the longitudinal axis between a forward orientation and a sideways orientation, wherein the longitudinal body includes a stern body, a bow body, and a hull body to which the stern body and the bow body are connectable;
a wing attached to the longitudinal body wherein the wing is moveable between a vertically extending wing orientation when the longitudinal body is in the forward orientation and a horizontally extending wing orientation when the longitudinal body is in the sideways orientation;
a propulsion system having a front propulsion device and a rear propulsion device that is arranged rearwardly along the longitudinal axis relative to the front propulsion device, the propulsion system providing thrust in a perpendicular direction relative to the longitudinal axis; and
an after-propulsion system arranged at a rear end of the longitudinal body that provides thrust along the longitudinal axis, wherein the after-propulsion system includes a propeller and a plurality of stators.

20. An underwater vehicle comprising:
a longitudinal body that defines a longitudinal axis and is rotatable about the longitudinal axis between a forward orientation and a sideways orientation, wherein the longitudinal body includes at least one moveable mass that moves the longitudinal body between the first orientation and the second orientation and maintains a buoyancy of the longitudinal body;
a wing attached to the longitudinal body wherein the wing is moveable between a vertically extending wing orientation when the longitudinal body is in the forward orientation and a horizontally extending wing orientation when the longitudinal body is in the sideways orientation;
a propulsion system having a front propulsion device and a rear propulsion device that is arranged rearwardly along the longitudinal axis relative to the front propulsion device, the propulsion system providing thrust in a perpendicular direction relative to the longitudinal axis; and
an after-propulsion system arranged at a rear end of the longitudinal body that provides thrust along the longitudinal axis.
