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.
The Ascender airship would operate between the ground and the Dark Sky Station at 140,000 feet (ca. 42,672 m). A long, V-shaped planform with an airfoil profile would provide aerodynamic lift to supplement the airship's inherent buoyancy, with the craft driven by propellers designed to operate in a near vacuum. The Ascender would be larger than ...
A hypothetical craft constructed using this principle is known as a vacuum airship. In 1709, the Brazilian-Portuguese Jesuit priest Bartolomeu de Gusmão made a hot air balloon, the Passarola, ascend to the skies, before an astonished Portuguese court.
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”.
Zero-emissions craft is designed to ‘fly forever’
These were far more capable than fixed-wing aircraft in terms of pure cargo-carrying capacity for decades. Rigid airship design and advancement was pioneered by the German count Ferdinand von Zeppelin. Construction of the first Zeppelin airship began in 1899 in a floating assembly hall on Lake Constance in the Bay of Manzell, Friedrichshafen ...
Jesuit Father Francesco Lana de Terzi describes in his treatise Prodomo a vacuum-airship-project, considered the first realistic, technical plan for an airship. His design is for an aircraft with a boat-like body equipped with a sail, suspended under four globes made of thin copper; he believes the craft would rise into the sky if air was ...
The Spirit of Goodyear, one of the iconic Goodyear Blimps. This is a list of airships with a current unexpired Federal Aviation Administration (FAA) [1] registration.. In 2021, Reader's Digest said that "consensus is that there are about 25 blimps still in existence and only about half of them are still in use for advertising purposes". [2]
