displacement. The toroidal hull will accommodate three cycloidal propellers 

 with rotor axes lying in the plane of the toroid. A steel, titanium, or 

 titanium-glass composite spherical personnel capsule will fit into the center 

 of the toroid. 



Vehicle Weight 



Three components are responsible for most of the vehicle weight. 

 Their estimated weights are: 



1. Lift Tanks 166,000 1b 



2. Propellers and Motors 61,650 1b 



3. Toroidal Hull and Miscellaneous 



Equipment 86,000 lb 



Total 313,650 1b 



The buoyancy of the lift tanks is estimated at 314,000 pounds.
