An airship support structure based on carbon fiber skeleton

Abstract

An airship support structure based on a carbon fiber skeleton belongs to the technical field of stratospheric airships and solves the problems existing in the stratospheric airship. There are three skeletons connecting the head cone and the tail cone on the outside. The three skeletons are evenly distributed along the circumference of the inflatable bag. The two connecting ends are inserted into the corresponding carbon fiber tubes and fixed by clamps or by bonding, and a spherical protrusion is arranged between the two connecting ends of the straight-through connecting piece; the present invention is used for stratospheric airships.

Description

technical field [0001] The invention belongs to the technical field of stratospheric airships, in particular to an airship support structure based on a carbon fiber skeleton. Background technique [0002] The stratospheric airship has the advantages of large load, long hovering time and reusability, and has important uses in regional disaster prevention and mitigation, regional communication, urban security monitoring, environmental monitoring, high-resolution real-time regional monitoring, etc.; The main structure of the airship is a huge inflatable bag, which relies on helium gas or air to maintain its shape, and has poor shape-keeping ability. It is affected by environmental factors such as pressure and temperature, and the overall shrinkage or expansion changes greatly, so it is necessary to set a support frame to control Its deformation is within the allowable range. At present, a skeleton composed of rigid carbon fiber tubes is generally used. It has the disadvantage o...

Problems solved by technology

[0005] The beneficial effects of the present invention are: since the skeleton is connected by carbon fiber tubes through strong elastic rubber connectors, it has the advantages of rigid-flexible coupling, that is, it can effectively solve the deformation of the inflatable bladder affected by environmental factors such as pressure and temperature. For larger problems, it plays a good role in supporting and maintaining shape, and when encountering a large deformation in a harsh environment, the skeleton is not easy to be brittle, and can still play a good role in supporting and maintaining shape, and can be used in Restoration after the environment is improved; during processing, the size, wall thickness, and concentricity or eccentricity of the spherical protrusion can be set according to the needs of the elastic force; the connection structure of the skeleton is simple, light in weight, and low in production cost; the pod can be hung on a skeleton at the bottom Below, since the skeleton is set outside the inflatable bag, it can effectively control the deformation of the inflatable bag, thereby reducing the lifting displacement of the pod due to the influence of air pressure and temperature
