Abstract
A super-rigid hybrid airship having a modular structure with a central tube having a diameter of between 5 to 10% of the diameter of the airship, structural rings surrounding and preferably concentric with the central tube and connected to the tube by bolts; an external cover made from thin metal sheets, interspersed with composite resins and fibbers which is pressurized and pre-stressed by light gases and which is rigid, conductive, non-combustible and impermeable to gases; balloons filed with hydrogen and disposed in structural sections defined by neighboring structural rings; at least two interconnected cuffs inflated by atmospheric air serving as operational ballast and ensuring weight, pressure and volume balance of the airship. Preferably the airship has a blower system for dispersing air, arranged on the centerline of the top layer, wings arranged at each side of the fixed sections, and thrust means.
