Abstract
A pelagic free swimming aquatic vehicle includes a rigid forebody having a predetermined volume; a watertight chamber in the forebody; and a flexible afterbody having a lesser volume than the forebody and including a maneuvering and propulsion propulsion structure and a drive system for driving the structure with a traveling sinusoidal wave motion.
Claims24
A pelagic autonomous free swimming aquatic vehicle comprising:
- a submersible rigid forebody having a predetermined volume, said volume of said forebody is 50%-70% of the envelope displacement of the vehicle;
- a water tight chamber in said forebody;
- and
- a flexible afterbody having a lesser volume than said forebody and including a maneuvering and propulsion structure and drive system means for driving said structure with a traveling sinusoidal wave motion.

A pelagic free swimming aquatic vehicle comprising:
- a rigid forebody having a predetermined volume;
- a watertight chamber in said forebody;
- an energy source in said chamber, said energy source having an independent thermal engine;
- and
- a flexible afterbody having a lesser volume than said forebody and including a maneuvering and propulsion structure and drive system for driving said structure with a traveling sinusoidal wave motion.
