Abstract: FIELD: flying vehicles with adjustable aerostatic lift force. SUBSTANCE: airship includes envelope 1 made from several layers of inflatable longitudinal pneumatic beams 2,3 and 4. Cavities of pneumatic beams 2,3 and 4 are connected with inner cavity of envelope 1 by means of pneumatic drives 6 through charging/emptying system. In transferring the carrier gas from inner cavity of envelope 1 to pneumatic beams 2,3 and 4, beams are inflated reducing perimeter of envelope 1 and consequently its volume. Reduced volume of carrier gas in envelope reduces aerostatic lift force. Layer-by-layer distribution of carrier gas makes it possible to inflate considerable amount of this gas in pneumatic beams 2,3 and 4 not exceeding ultimate strength of standard materials, thus providing for regulation of aerostatic lift force in wide range. EFFECT: increased range of regulation of aerostatic lift force. 3 dwg
