Abstract: A hybrid stratospheric airship for the combined and optimized use of aerostatic and aerodynamic force, including: an inflatable central body; a first and second inflatable wing extending from the central body protruding laterally from two opposite sides of the central body, each wing having a portion proximal to the central body, an end portion distal from said central body, a leading edge, and a trailing edge; an outer shell having a main shell portion associated with the main body, and a first and a second side shell portion associated with each wing, respectively; at least one main spar extending transversely to the central body, which supports the first and second wing and crosses the central body, the at least one main spar a rectilinear spar interposed between the leading edge and the trailing edge of the first and second wings, and connected to the distal end portions of the wings.
