AIRSHIP Russian patent published in 1994 - IPC

FIELD: construction of airships. SUBSTANCE: airship has several frames with longerons 8,9 and 10 of load-bearing framework for hulls creating the lift force mounted in between them. Frames divide load-bearing framework into longitudinal cells 1 and consist of three cross members 2,3 and 4 located in form of isosceles triangle. Tetragonal surfaces formed in longitudinal cells 1 and limited by two cross members 2 and 5, 3 and 6, 4 and 7 and longerons 8, 9 and 10 are provided with tie rods 11 running diagonally. Hull creating the lift force is located and secured in longitudinal cells with its lower portion adjoining longerons 8, 9 and 10 from inside. When filled with gas, hull projects on side above cross members 2, 3, 4, 5, 6 and 7 and longerons 8, 9 and 10 and forms outer envelope of airship by its envelope along length of cell 1. EFFECT: enhanced ability and strength of airship at reduced mass of structure. 20 cl, 23 dwg
