Aerostats, commonly known as airships or blimps, are tethered or moored lighter-than-air aircrafts that obtain their buoyancy from contained lifting gases less dense than the surrounding air. Unlike free balloons, aerostats are steerable and have propulsion systems that allow controlled flight. Modern aerostats can stay aloft from several days to months depending on their size and payload. They are being used for various commercial, scientific and military applications that require ...
