Bionic, inflatable and deployable structure

Abstract

The invention relates to a bionic, inflatable and deployable structure. A trunk air chamber is contained in a central trunk. The upper portion of the structure is provided with a trunk end cover installed at the top of the central trunk. A main inflation inlet communicating with the trunk air chamber is connected to the central trunk in a sealed mode. An inflation switching valve is installed on the main inflation inlet. A plurality of branch inflation inlets communicating with the trunk air chamber are connected to the positions, on the two sides of the main inflation inlet, of the central trunk in a sealed mode correspondingly. Wing membrane sets on the sides each comprise a wing membrane, a main inflation vein and a linear main inflation vein, and the main inflation vein and the linear main inflation vein are embedded in the wing membrane. Each main inflation vein communicates with the corresponding branch inflation inlet on the same side. The linear main inflation veins are located in the main inflation veins. One ends of the linear main inflation veins communicate with the main inflation veins, and the other ends of the linear main inflation veins communicate with the branch inflation inlets in the same side. The main inflation veins and the linear main inflation veins are all embedded into the wing membranes. The bionic, inflatable and deployable structure does not need to be driven by a motor, and is ingenious in structure and low in weight, and a large deployable area can be obtained through a small folding size.

Description

technical field [0001] The invention relates to an expandable structure, in particular to a bionic inflatable expandable structure based on the development and development of a butterfly's emergence. Background technique [0002] With the continuous development and wide application of spacecraft technology, the structure and function of the spacecraft are constantly changing and becoming more and more complex. Various structures and mechanisms are required to complete the corresponding tasks. As an important structure, the deployable structure has become a spacecraft structure an essential component of. A deployable structure is a structure that realizes a certain part of a spacecraft from an initial collapsed configuration to a final deployed configuration and maintains this configuration. It is widely used in the aerospace field, such as satellite deployment antennas, spacecraft solar arrays, planetary Rover solar panels, alien space base modules and vehicles, and more. ...

AI Technical Summary

Problems solved by technology

The space deployable mechanism is limited by the volume and weight of the space transportation system, and usually has a large deployment / contraction ratio and high system reliability. Its research and implementation face a series of theoretical, methodological and technical challenges.

[0003] At present, most space expandable structures use driving devices and rigid trusses to realize the expansion of the structure. Since the trusses and driving devices are both rigid, the storage rate is relatively low and the mass is large, which is limited by the carrying capacity of the vehicle. The application of traditional rigid space deployable mechanism
