Implementing a Low-Cost Long-Range Unmanned Underwater Vehicle: The SeaDiver Glider

Abstract

The SeaDiver Glider is an UUV (Unmanned Underwater Vehicle) used for underwater prospecting at a low cost with a long distances coverage (approx = 1400 miles). It moves without propellers by changing its buoyancy with the help of ballast and its hydrodynamics profile reminiscent of a wing (model NACA0022). Ballast inflation makes it raise the surface, ballast deflated make it submerge the bottom. Ballast is positioned in front of its structure in an optimal position to use the lift of its shape. This up-and-down movement is converted into horizontal displacement by the wing-shape of the SeaDiver Glider. It mimics sinusoidal movements from the sea surface down to 300 feet underwater. This vehicle is able to traverse from one point to another without human intervention.
