ABSTRACT:
A variable density aircraft is formed of at least one variable volume container such as a balloon, gas cell, or collapsible hinged panel hull which is supplied with a gas for container expansion and comtraction by an aircraft carried reversible, fluid expansion/contraction system. The variation of the volume of such containment device without a commensurate variation of mass results in a densemetric variation in the aircraft.
