Abstract

An underwater shock generation system and method uses an electrolysis generator supplied with an electrolytic liquid to generate an ignitable gas. A housing stores the ignitable gas and is adapted to be disposed in a water environment. An igniter is provided and is operable to ignite the ignitable gas stored in the housing to generate an explosion in the underwater environment. The housing is shaped to control a direction of propagation of the explosion in the water environment.

First claim

What is claimed as new and desired to be secured by Letters Patent of the United States is:

1. A system, comprising:
an electrolysis generator adapted to be supplied with an electrolytic liquid and operable to generate an ignitable gas using the electrolytic liquid;
a housing storing the ignitable gas, said housing adapted to be disposed in a water environment;
an igniter operable to ignite the ignitable gas stored in said housing to generate an explosion in the water environment; and
said housing shaped to control a direction of propagation of the explosion in the water environment.

2. The system of claim 1 , wherein the electrolytic liquid is selected from the group consisting of
seawater,
seawater mixed with at least one additive selected from the group consisting of a salt and freshwater, and
freshwater mixed with at least one electrolyte.

3. The system of claim 2 , wherein said at least one electrolyte comprises a salt.

4. The system of claim 1 , wherein said housing includes a conical portion storing the ignitable gas.

5. The system of claim 1 , further comprising a compressor operable to increase pressure of the ignitable gas stored in said housing.

6. The system of claim 1 , wherein the ignitable gas comprises oxyhydrogen gas.

7. A system, comprising:
a housing adapted to be disposed in a seawater environment;
an electrolysis generator mounted in said housing and adapted to receive seawater from the seawater environment, said electrolysis generator being operable to generate an ignitable gas using the seawater;
a sealed chamber within said housing and coupled to said electrolysis generator wherein the ignitable gas is stored in said sealed chamber; and
an igniter disposed in said sealed chamber and operable to ignite the ignitable gas to generate an explosion;
wherein said sealed chamber has walls shaped to control a direction of propagation of the explosion through said housing and into the seawater environment.

8. The system of claim 7 , wherein said housing is tubular.

9. The system of claim 7 , further comprising at least one additive for inclusion with the seawater received by said electrolysis generator, said at least one additive selected from the group consisting of a salt and freshwater.

10. The system of claim 7 , wherein said sealed chamber is conical.

11. The system of claim 7 , further comprising a compressor disposed in said housing and operable to increase pressure of the ignitable gas in said sealed chamber.

12. The system of claim 7 , wherein the ignitable gas comprises oxyhydrogen gas.

13. A method, comprising:
by an underwater shock generator having a housing adapted to be disposed in a seawater environment, an electrolysis generator mounted in the housing, a sealed chamber disposed in the housing and coupled to the electrolysis generator, and an igniter disposed in the sealed chamber,
admitting seawater from the seawater environment into the housing;
directing the seawater admitted from the seawater environment into the electrolysis generator wherein the electrolysis generator operates to generate an ignitable gas using the seawater;
storing the ignitable gas in the sealed chamber; and
activating the igniter to ignite the ignitable gas to generate an explosion, wherein the sealed chamber has walls shaped to control a direction of propagation of the explosion through the housing and into the seawater environment.

14. The method of claim 13 , wherein the housing comprises an underwater vehicle, the method further comprising maneuvering the underwater vehicle in the seawater environment.

15. The method of claim 13 , further comprising:
mixing at least one additive with the seawater prior to the step of directing, wherein the at least one additive is selected from the group consisting of a salt and freshwater.

16. The method of claim 13 , wherein the sealed chamber is conical.

17. The method of claim 13 , further comprising:
increasing, by a compressor coupled to the sealed chamber, pressure of the ignitable gas in the sealed chamber.

18. The method of claim 13 , wherein the ignitable gas comprises oxyhydrogen gas.
