WebLaw Design for a High Altitude Airship Joseph B. Mueller∗ and Michael A. Paluszek† Princeton Satellite Systems, Princeton, NJ 08542 Yiyuan Zhao‡ University of Minnesota, Minneapolis, MN 55455 Lighter-than air vehicles are an attractive solution for many applications requiring a sustained airborne presence. WebAt airspeeds below about 260 kn (480 km/h; 130 m/s; 300 mph), air can be considered incompressible in regards to an aircraft, in that, at a fixed altitude, its density remains nearly constant while its pressure varies. Under this assumption, air acts the same as water and is classified as a fluid .
