太阳望远镜采用全开式圆顶有许多好处,但是此时风对望远镜产生比较大的扰动。为了减少风对望远镜的影响,设计了阻导风板,并在实际应用中得到了很好的结果。全面介绍了阻导风板的原理、结构,并给出了设计要点及在1 m红外太阳望远镜(New Vacuum Solar Telescope,NVST)上的实测结果。 |

Solar Telescopes often work without domes,but are set up near large water surfaces such as those of seas or lakes.Such a strategy keeps good seeings at the sites,but on the other hand,the air flow between land and water may cause vibrations of telescopes.To reduce the negative effects,we have designed and installed a set of Hindering and Steering Windscreens for our NVST(New Vacuum Solar Telescope).We report in this paper key design points and encouraging results.Our H-S Windscreen consists of three parts:(1) The first is a wind deflector consisting of many rectangular lamellas.Long edges of a lamella are flatly set on the supporting frame,and the plane surface of the lamella has a specific angle from the horizontal level decided by numerical simulations.The material for lamella is of low thermal conductivity to avoid strong heat exchange.(2) The second is a curved wind baffle the height of which is adjustable according to the telescope pointing.(3) The third is a circular supporting frame,which turns around according to wind directions.The H-S Windscreens have been put into use with the NVST at the Fuxian Lake Solar Observing Station since August 2010.We give some test results.The H-S Windscreen can reduce the wind force by an order of magnitude and the wind-speed variation.The design of the NVST windscreen is thus successful in reducing the effect of wind force on the telescope and in increasing observation time. |
