"aerostats"

“AIRSHIPS”

.

(from Greek ἀήρ aer (air) + στατός statos (standing) through french)

.

(an aerostat is a ‘lighter than air’ craft that gains its lift through the use of a ‘buoyant gas’)

Aerostats include unpowered balloons and powered airships.

A balloon may be free-flying or tethered.

The average density of the craft is lower than the density of atmospheric air, because its main component is one or more gasbags, a lightweight skin containing a lifting gas to provide buoyancy, to which other components such as a gondola containing equipment or people are attached.

(especially with ‘airships’, the ‘gasbags’ are often protected by an ‘outer envelope’)

(‘aerostats’ are so named because they use aerostatic lift which is a buoyant force that does not require movement through the surrounding ‘air mass’)

(this contrasts with the heavy aerodynes that primarily use aerodynamic lift which requires the movement of a wing surface through the surrounding air mass)

(the term has also been used in a narrower sense, to refer to the statically tethered balloon in contrast to the free-flying ‘airship’)

.

(this article uses the term in its broader sense)
