An apparatus for underwater propulsion. The apparatus may include a hydrofoil, a buoyancy compensator connected to the hydrofoil, a tank containing air, and a controller regulating the passage of air from the tank into the buoyancy compensator. The controller may also regulate the escape of air from the buoyancy compensator. By positioning the hydrofoil underwater and alternating between positive and negative angles of attack, a diver may generate forward propulsion by manipulating the controller to correspondingly alternate the buoyant force produced by...
What is claimed and desired to be secured by United States Letters Patent is: 1. A method of underwater propulsion comprising: equipping a user with a buoyancy compensator comprising a controller, tank containing at least one gas, and an expander, the tank being operably connected and pressurized to deliver the at least one gas to the expander under the control of the controller; providing a hydrofoil; connecting the hydrofoil to the user; positioning the user and hydrofoil underwater at a selected depth; programming into the controller data effectively...
