Aerostat
Aerostat
Aerostat (pronounced: /ˈɛərəˌstæt/) is a term derived from the Greek words 'aero' meaning air and 'stat' meaning standing. It refers to a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include free balloons, airships, and moored balloons. An aerostat's main structural component is its envelope, a lightweight skin containing a lifting gas to provide buoyancy, to which other components are attached.
Types of Aerostats
- Free Balloon: A free balloon is an unpowered aerostat. Without a method of propulsion, free balloons drift with the wind.
- Airship: An airship or dirigible balloon is a type of aerostat that can be steered and propelled through the air using rudders and propellers or other thrust mechanisms.
- Moored Balloon: A moored balloon is an aerostat that remains tethered to the ground by means of a cable.
Applications of Aerostats
Aerostats have been used for various purposes, including meteorological observations, defense surveillance, advertising, and in the entertainment industry for aerial views during sports events.
