Abstract

The invention relates to a novel gasbag for an airship. An air bag (1) is provided with one or more air openings (1-1) and a pair of helium openings A (1-2). The pair of air opening (1-1) and the pair of helium openings A (1-2) are provided with valves respectively, a pair of helium bags (2) are provided with helium openings B (2-1) respectively and arranged in the air bag (1), the helium openings B (2-1) of the pair of helium bags (2) are located at the helium openings A (1-2) in the air bag (1) respectively and coincide with the helium openings A (1-2), and a bracing wire (3) is installed in the air bag (1) and located between the pair of helium bags (2). The novel gasbag for the airship has the advantages that the pressure of helium in the helium bags and the pressure of air in the air bag are in balance, the pressure difference value is very small, and therefore helium leakage caused by the pressure difference is reduced.

Description

technical field

[0001] The invention relates to the field of airships, in particular to a novel airbag for airships. Background technique

[0002] At present, the known soft pressure airship airbag is composed of a main airbag and one or more auxiliary airbags and valves built in the airbag. The diaphragm of the auxiliary airbag is placed in the cavity of the airbag to separate the airbag into a helium space and an air space. . The helium space is called the main airbag, which is filled with helium; the air space is called the secondary airbag, which is filled with air, which is used to discharge or supply inward to the inner cavity of the airbag when the helium expands or contracts. The volume change of the helium when the air supplements the expansion or contraction of the helium keeps the volume of the airbag constant. The pressure of the air in the secondary airbag and the helium in the main airbag is higher than that of the outside atmosphere, so that the airbag mai...
