LTA

The term Lighter than air (LTA) ("plus léger que l'air") refers to the set of technologies associated with balloons and dirigibles. This was the prevailing type of aircraft design, as reflected by successful patents, in the 19th century and at the beginning of the 20th century.

On Wikipedia: Articles "Aerostat", "Balloon (aeronautics)", and "Airship" discuss the operation and history of these vessels.

Articles "Lighter than air" and "Lifting gas" discuss the physical properties and uses of different gasses which are lighter than air.

In the US patent classification system, USPC 244/24 is a top-level category for lighter-than-air aircraft, while USPC 244/96, falling under a different branch of classification (for navigation) deals with (mostly vertical?) control over LTA aircraft.

Berget, 1909, Conquest of the Air, p. 3:

I may state the fundamental principle of aerostation in a very few words.

Archimedes discovered it, and formulated it as follows:

Every body plunged into a fluid is subjected by this fluid to a "pressure" from below to above, which is equal to the weight of the fluid displaced by the body.
