Aerostat
Definition
A flying apparatus lighter than air, whose sustenance and ascent in the atmosphere rely on Archimedean force (static lift), being filled with a gas less dense than the surrounding air (such as helium, hydrogen) or with hot air. This structural category encompasses free balloons, captive balloons, and mechanically propelled airships.
