Abstract

The aircraft is designed for vertical takeoff and landing, and is made of an inflatable canvas with convex upper and lower circular faces and a central propulsion unit (11), in an axial passageway. The canvas encloses a succession of concentric toroildal tubes with diameter decreasing radially outwards. A toroidal cap (20) encloses the upper rim of the inner tube, and covers the outer aerodynamic canvas (17). Between the cap (20) and the canvas (17) is a generator for powering the passenger airship, comprising motors (25,26) coupled to coaxial propellors.
