Abstract

A lighter than air semi-rigid air vehicle utilizing two or more spherical chambers with composite fairings in between to reduce drag. The vehicle also may utilize a reverse ballonet or conventional ballonet system for the lift gas control (Helium, Hot Air, Hydrogen or any other lift gas). The power plants may use reversible pitch propellers to enhance maneuverability.
