FIELD: fire-fighting technique; extinguishing large-scale fires. ^ SUBSTANCE: proposed fire airship includes disk-shaped aerostatic body, power plants with variable thrust vector, crew cabin with control system, landing gear and mooring arrangement. Body consists of upper and lower elastic convex envelopes whose edges are secured on frame which is closed over perimeter ; this frame is connected with tubular member by means of rigid radial beams forming the central compartment; said tubular member is located along vertical axis of aerostatic body whose cavity is divided by inclined gas-tight membrane into lighter-than-air compartment containing the bottles charged with this gas and thermal ballasting compartment located under first one. Upper and lower convex envelopes are provided with upper load-bearing ring secured on end face of tubular member and lower load-bearing ring with sleeve forming the cargo compartment. Inner and outer edges of gas-tight membrane are secured respectively on closed frame and on lower load-bearing ring which is connected with closed frame and with rigid tubular member by means of longitudinally rigid members. Water tank installed in cargo compartment is connected by means of flexible hose with pipe mounted coaxially relative to rigid tubular member; pipe terminates in funnel secured on upper load-bearing ring. Water tank is provided with outlet pipe for forming water packs dropped onto burning site. ^ EFFECT: enhanced efficiency of fire-fighting. ^ 4 cl, 6 dwg |
