Abstract
A submersible vessel comprising: an elongated hull; at least one propeller mounted on a forward end of said hull and adapted to move said hull through water; said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and thence along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds.
Claims19
A submersible vessel comprising:
- an elongated hull;
- at least one propeller mounted on a forward end of said hull and adapted to move said hull through water, said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and thence along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds;
- a conning tower, said conning tower comprising a forward end and a rearward end;
- and
- a plurality of nozzles disposed on said forward end of said conning tower, wherein said plurality of nozzles are configured to release a friction-reducing fluid, whereby the friction-reducing fluid displaces water from the surface of said conning tower so as to diminish friction on the surface of said conning tower and facilitate high speeds.

A method for moving through water, the method comprising:
- providing a submersible vessel comprising:
- an elongated hull;
- at least one propeller mounted on a forward end of said hull and adapted to move said hull through water, said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and thence along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds;
- a conning tower, said conning tower comprising a forward end and a rearward end;
- and
- a plurality of nozzles disposed on said forward end of said conning tower, wherein said plurality of nozzles are configured to release a friction-reducing fluid, whereby the friction-reducing fluid displaces water from the surface of said conning tower so as to diminish friction on the surface of said conning tower and facilitate high speeds;
- submerging at least a portion of the elongated hull;
- and
- rotating the at least one propeller so as to move the submersible vessel through water.
