ABSTRACT:
A rigid airship is disclosed herein having an annular or toroidal airfoil fuselage in front elevation for housing several elongated gas cells containing a buoyant gas such as helium. The fuselage includes at least two longitudinal and a plurality of transverse structural members for supporting the cells. A covering is provided about the fuselage comprising a multiplicity of fitted panels joined by retainer straps and locking nodes. The fuselage defines a central venturi having an annular intake and a contracted exit through which an elongated tapered tail cone extends in coaxial relationship with the fuselage. Boundary layer control is effected via manifolds associated with the fuselage panels and a variable geometry venturi passageway is effected by longitudinal movement of a control compartment and adjoining tapered tail cone. Propulsion apparatus is carried after the venturi contraction and an electrical power regeneration and storage system is integrated with electrodes carried on the panels for electrokinetic propulsion.
