阿波罗进军Moon的数据采集
美国的阿波罗太空计划是在1960年代末到达广寒宫的,它是一项雄心勃勃的大胆尝试,主要依靠数据采集(DAQ)来监视和自动化从最后倒计时返回着陆的飞行过程。
本文探讨了阿波罗期间飞行数据采集的一些硬件和技术。然后将过去的这些技术与它们的现代等价物的例子进行比较,以进行DAQ的最先进的传感和转换。
一个巨大的飞跃
1969世纪50年代末和60年代初,的技术很难在月球表面得到Neil Armstrong的引导打印,但这不仅仅是先进的硬件/软件系统。
阿波罗计划的范围和供应商的多样性,以及前所未有的任务范围,意味着大量的合作和互操作与纯技术发展并行。阿波罗计划的管理是为了协调大规模的系统设计和制造,包括从设施到海岸的供应商的集成和结算。
Three major systems evolved during the manned missions of Apollo: Multistage Booster Rocket (Saturn V), Command/Service Module (CSM), and Lunar Module (LM)。 Each of these elements – hugely complex in their own right – required meticulous fabrication and integration. Assembling, testing, and ultimately flying the entire rocket stack was more complex still, but smart minds and copious taxpayer funds ultimately found a way to get it done.
Well-defined and efficient interfaces between spacecraft elements allowed three different rocket-stage suppliers (Boeing, North American Rockwell, and McDonnell Douglas) to synchronize with a capsule supplier (North American Rockwell) and a Lunar Lander supplier (Grumman) over large distances, offering integration at several NASA facilities. Of course these contractors – and there were many others - had their own suppliers/sub-contractors, so the supply chain ran deep, as did the technical elements of the Apollo’s systems.
