A vacuum airship, also known as a vacuum balloon, is a hypothetical airship that is evacuated rather than filled with a lighter-than-air gas such as hydrogen or helium. First proposed by Italian Jesuit priest Francesco Lana de Terzi in 1670, [ 1 ] the vacuum balloon would be the ultimate expression of lifting power per volume displaced.
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying under its own power. [1] Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne.
Francesco Lana de Terzi's design for a flying boat, 1670 Francesco Lana de Terzi's flying boat concept c.1670. In the year 1670, Francesco Lana de Terzi published a book titled Prodromo, including a chapter titled saggio di alcune invenzioni nuove premesso all'arte maestra ("Essay on new inventions premised on the master art"), which contained the description of a “flying ship”.
Francesco Lana de Terzi's airship c.1670. One of the earliest proposals for a flying machine based on rational principles was Francesco Lana de Terzi's design for a vacuum airship, c.1670. He had measured the pressure of air at sea level and based on this he proposed the first scientifically credible lifting medium in the form of hollow metal ...
