Aerostat (disambiguation)

An aerostat is an aircraft that remains aloft through the use of lighter-than-air gases. A narrower and more technical meaning refers only to tethered balloons.

Aerostat may also refer to:

Airships

Airships are powered aerostats:

  • Airship, or dirigible, any aerostat that can be manoeuvred through the air using propellers, rudders, etc.
  • Blimp, an airship with no structural framework, using only gas pressure to maintain its shape
  • Rigid airship, uses only a structural framework to maintain its shape
  • Semi-rigid airship, uses a partial structural framework in combination with gas pressure to maintain its shape
