1000天的第一个光:珀斯-洛厄尔望远镜设施的建设1968-71
1000 Days to First Light: Construction of the Perth-Lowell Telescope Facility 1968-71
摘要:
1968年开始谈判在珀斯天文台为美国宇航局的国际行星巡逻网络建立一个望远镜设施。1,000天后,望远镜看到了第一束光。该设施与其他天文台没有任何相似之处。在一个圆顶内,望远镜坐落在一个42英尺高的混凝土墩上,有一个环绕的楼梯和混凝土腿。周围的森林与圆顶的高度相似,其设计与直觉相反。这项研究调查了为什么,在损害性能的风险,有偏离标准设计,并确定决策的驱动程序。天文台的游客了解到一位政府建筑师,塔德乌什·安杰贾切克,他异想天开,连续增加了结构的高度。虽然是与代理政府天文学家伯特兰·哈里斯合作设计的,但一个公务员建筑师不可能对一个科学装置产生如此大的影响。通过在结构上设计较大的强度和刚度来改善振动。采用遮阳鳍和保护墙等功能降低了热膨胀和风应力,并通过简单地使其变高来解决地面热干扰。视宁度测量不是重要的设计考虑因素。该设施存在于其目前的楼层高度,因为连续批准的修改。最初的设计是由哈里斯和重新设计的要求来自他,但在密切谈判的Andrzejaczek谁想要一个未来的形状和比例的结构。哈里斯的设计受到他个人的英国背景和他作为天文学家工作的旧珀斯天文台的影响。Andrzejaczek的设计受到他出生城市的天文台,他与当代设计师的一致性以及他的艺术天赋的影响。
英文摘要:
Negotiations began 1n 1968 for a telescope facility at Perth Observatory for NASA's International Planetary Patrol Network. 1,000 days later the telescope saw first light. The facility bears no resemblance to other observatories. Inside a dome, the telescope sits on a 42 ft tall concrete pier with a wrap-around staircase and concrete legs. Surrounding forest is similar in height to the dome, the design of which is counter intuitive. This study investigated why, at the risk of compromising performance, there was a departure from standard design, and to to identify drivers for the decision making. Observatory visitors learn of a government architect, Tadeusz Andrzejaczek who made whimsical, successive increases to the height of the structure. Though designed in collaboration with Acting Government Astronomer, Bertrand Harris, it is improbable that a public servant architect would have such influence over a scientific installation. Vibration amelioration was met by designing massive strength and rigidity into the structure. Thermal expansion and wind stresses were reduced using features such as shade fins and protective walls, and ground thermal disturbance was addressed by simply making it tall. Seeing measurements were not a significant design consideration. The facility exists with its current floor height because of successive approvals for modification. The initial design was by Harris and requests for redesigns came from him but in close negotiation the Andrzejaczek who desired a structure of futuristic shape and proportions. Harris's designs were influenced by his personal English background and the Old Perth Observatory where he worked as an astronomer. Andrzejaczek's design was influenced by an observatory in his birth city, his alignment with contemporary designers and his artistic flair.
