Effect of wing loading on gross takeoff mass of a hybrid buoyant aircraft

Aerostatic lift in a hybrid buoyant aircraft reduces the wing loading as well as the induced drag. This reduction is valid till pressure height. In this paper, the existing analytical relationships for the gross and net mass, as well as wing loading of standard aircraft, are modified to obtain new a...
