nU-Boats

Because inflation pressure is radial outward and equal in all directions a sphere, a torus or a cylinder are the inflatable primitives.

A buoyancy engine like those typically found in undersea gliders is used to adjust the density of the platform to match that at the desired depth.

nU-Boats are hydraulically inflated with a variety of liquids ranging from fresh water to various hydrocarbons or a liquid form of syntactic foam, which provide incompressible, depth-independent buoyancy.

nU-Boats are a radical departure in the design, materials, construction and capabilities of Autonomous Underwater Vehicles (AUV).
