Structural design analysis of wind screen for Antarctic 2m-class optical telescope

The completely open dome provides excellent dome Seeing, but at the same time wind loads are applied directly to the telescope, and the wind screen structure can be a good solution to this contradiction. The effects of the wind screen structure on the wind speed around the telescope, dome Seeing, mirror wind pressure, etc. are investigated by simulation and wind tunnel tests, and the optimal wind screen transmittance, structural rod size, and the distance between the wind screen and the telescope are finally obtained.
