美航宇局(NASA)大幅度地变更的1986年5月刚刚发表的空间站计划方案,比当初预定的规模更小。美航宇局放弃了开始运用的空间站构型——双龙骨型结构,而采用横向延伸的 H 型构型来代替它。H 型两侧的纵杆装有太阳能电池帆板,在横梁桁架的构造上,安装居住舱和实验舱。空间站的规模缩小反映了航天飞机飞行次数减少和预算削减。据美国航宇局的约翰逊空间中心的前空间站计划主任 N·哈钦森透露,空间
The space station plan, just released by NASA in May 1986, was smaller than originally planned. NASA abandoned the configuration of the space station in use, the double keel-type structure, and replaced it with a transversely extending H-configuration. H pole on both sides of the longitudinal pole equipped with solar panels, beams in the truss structure, the installation of accommodation and experimental cabin cabin. The reduction of the space station reflects the reduction of space shuttle flights and budget cuts. According to N Hutchinson, former space station program director at NASA’s Johnson Space Center, Space
