Annular aerostat for carrying astronomical telescope

Abstract

The invention discloses an aerostat for carrying an astronomical telescope, and belongs to the technical field of aerostat structures. The aerostat comprises an annular inflatable airbag, a load platform and three fixing rings, wherein the three fixing rings are uniformly distributed along the circumferential direction and locked on the annular airbag, and the fixing rings are used for supporting and fixing other structures; and the load platform is fixed at the center position of the airbag through a steel rope and a steel pull wire, and the load platform is communicated with the fixing rings through a cableway. The load platform of the aerostat disclosed by the invention is positioned at the annular middle part, so that the integral center of gravity does not exceed the center of mass; and meanwhile, an instrument on the load platform can be used for performing sky observation, the structure layout is reasonable, and power self-support can be realized.

Description

technical field [0001] The invention relates to an aerostat, in particular to an aerostat for carrying an astronomical telescope, and belongs to the technical field of aerostat structures. Background technique [0002] An aerostat is a lighter-than-air aircraft that can control its flight state autonomously. The air bag of the hull is filled with a buoyant gas (such as hydrogen or helium) with a density lower than air, so as to generate buoyancy to lift the aerostat into the air. Large civil aerostats can be used for transportation, transportation, entertainment, disaster relief, film and television shooting, scientific experiments and so on. [0003] The existing aerostat technology is to expand and apply its functions under the classic shape of the original aerostat. The design of the aerostat with this structure can only be pod-shaped or embedded in the bottom of the airbag for the load platform. , more suitable for aerial photography and earth observation. However, wh...

AI Technical Summary

Problems solved by technology

However, when it is applied to sky observation, the load must be designed on the upper part of the airbag, which will increase the height of its center of gravity and reduce the balance of the aerostat

In order to lower the center of gravity, the bottom of the airbag must be counterweighted accordingly, which increases the overall weight of the aerostat

[0004] At the same time, there is no good connectivity between the various parts of the aerostat. When a certain module or component needs to be repaired under special circumstances when the aerostat is working in the atmosphere, the staff cannot immediately go to the corresponding part for repair, and sometimes even You can only return to the base, which increases the time cost

Finally, the existing aerostats all have their own energy source. In the case of limited energy, the working time and range of the aerostat are limited to a certain extent.
