Embodiment Construction

[0014] figure 1 It is a schematic diagram of the connection structure between the air storage cabin and the buoyant airbag of the present invention. It can be seen from the figure that an inflatable airship includes a load compartment 5, a plurality of buoyant airbags 4, and a power propulsion control system, which is characterized in that the multiple The buoyant airbags 4 are respectively connected with the inflation and deflation control device 2 and the air storage chamber 1 through the pipeline 3 in sequence.

[0015] The inflation and deflation control device 3 includes a sealing valve (such as a two-way metal sealing butterfly valve), an air compression pump, or a vacuum pump, or a combination thereof.

[0016] The buoyant airbag 4 is flexible, and is made of airtight balloon cloth, or fiber fabric of materials such as polyamide and polyester coated with a gas-barrier coating on the surface.

Abstract

The invention belongs to the technical field of aircraft manufacturing, and relates to an inflation airship. The inflatable airship is characterized in that a plurality of buoyancy lift air bags are sequentially connected with an inflation and deflation control device and an air storage cabin through pipelines; and the inflation and deflation control device comprises a sealing valve and an air compression pump or a vacuum-pumping pump or a combination thereof. The inflation airship has the advantages that: the structure of the airship is simple, the flow direction of helium gas can be controlled by hands or electronic switching programs with convenient operation, the expansive helium gas transfers between the air storage cabin and the buoyancy lift air bags without external leakage, and the running cost is low. When the helium gas in the air storage cabin transfers to the buoyancy lift air bags through the sealing valve and the inflation and deflation control device, the volume of the air bags is increased, the buoyancy is increased, and the airship ascends; and otherwise, the helium gas in the buoyancy lift air bags transfers to the air storage cabin, the volume of the buoyancy lift air bags is reduced, the buoyancy is reduced, and the airship descends. The inflation airship also can be used in rural areas with poor road conditions, and when meeting barriers or swamps in the direction of forward motion, the inflation airship can bypass roadblocks through levitation and continue to land and go forward.

Description

technical field [0001] The invention belongs to the technical field of aircraft manufacturing, and in particular relates to an inflatable airship with adjustable buoyant airbag volume. Background technique [0002] Due to the advantages of vertical take-off and landing, long-term fixed-point hovering, and low noise, airships have been closely watched by scientific and technological personnel for more than a hundred years. A few, such as Chinese Patent Publication No. CN101020500, claim to inject ordinary air into the shell interlayer with an air gun, and use the larger volume of vacuum space surrounded by the shell to generate buoyancy, which can form an airship, a castle in the air or an air entertainment city, but there is no specific implementation Way. Most of the buoyant airbags on airships are filled with lighter gases such as helium and hydrogen to obtain buoyancy. Because hydrogen is flammable and explosive, and helium is an inert gas with inactive chemical propert...
