Geostationary Solar Powered Airship
May-01-09
U.S. Defense contractor Lockheed Martin is developing a $400 million airship surveillance and telecommunications platform called the High Altitude Airship (HAA).The HAA is an un-tethered, unmanned lighter-than-air vehicle that will operate above the jet stream in a stationary position. The airship will be able to survey a 600-mile diameter area to deliver telecommunications relay, weather data or surveillance.
The ship will be built using high-strength fabrics to minimize hull weight. Lift is provided by helium and leakage, as well as migration of air and water vapor into the helium enclosure, will be minimized by the envelope design.
