NASA空间站向工程设计人员提出一项新的挑战,此项重任将综合运用NASA25年载人和不载人空问飞行的经验,研制第一个载人飞行结构,准备提供“永久性载人空间站”,其工作寿命可从几年到几十年,而不象以前载人计划那样只有几天或几周。长寿命,规模逐步发展,高功率和自主性等系统一级的要求对空间站的制导、导航和控制(GNC)分系统提出了一些特殊要求。其中许多要求将会影响空间站的结构,反过来又影响GNC分系统。本文讨论空间站GNC分系统对系统级的功能要求,并介绍方案研制组所进行的结构综合研究结果。
The NASA Space Station presents a new challenge to engineering designers, which will combine the experience of 25 years of NASA’s private and private pilots with the development of the first manned flight structure to provide a “permanent manned space station ”And its working life can range from years to decades, unlike previous manned programs that only a few days or weeks. System-level requirements such as long life, gradual scale, high power and autonomy put forward some special requirements for GNSS subsystems. Many of these requirements will affect the structure of the space station and, in turn, the GNC subsystem. This article discusses the GNC subsystems station system-level functional requirements, and introduced the program development team conducted a comprehensive structural study results.
