项目摘要

The Two-Dimensional High Voltage Solar Array (2D/HV) Experiment was developed in order to demonstrate a structural enlargement of the solar array panel and an efficient power generation using high voltage in space. It has a triangle membrane compactly packed by a special folding method and solar cells electrical connected in series on its surface. The high voltage power generation in space is possible to cause the ionospheric plasma interactions. The Japanese and Americal investigators studied cooperatively the space environmental interactions. Our results were devoted to the development of the flight hardware and the software of the space operation.The 2D/HV was executed onboard a Japanese reusable free-flying platform "Space Flyer Unit" (SFU) on May 1995. The 2D/HV and SFU were controlled from Sagamihara Operation Center (SOC) in Japan. The Japanese and American investigators operated successfully the 2D/HV in SOC and acquired the flight data. Monitor cameras onboard SFU imaged a sequence to deploy and retract the 2D/HV in space. The Japanese and American investigators analyzed cooperatively the flight data and compared with our numerical simulations.The SFU was retrieved by the Space Shuttle Endeavor on January 1996. The SFU and 2D/HV are the first flight hardware to retrieved to ground after one year space flight in Japan. In order to perform the retrieval mission successfully a lot of technicl meetings and discussions with NASA were held in 1994 and 1995. The flight hardware of the 2D/HV was investigated as a post flight activities in 1996. All of the flight experiments in SFU was reviewed in America and Japan.

二维高压太阳能阵列（2D/HV）实验是为了演示太阳能阵列面板的结构扩展和利用空间高压高效发电而开发的。它有一个三角形的薄膜，用一种特殊的折叠方法紧密地包裹着，太阳能电池在其表面串联在一起。空间高压发电有可能引起电离层等离子体相互作用。日本和美国的研究人员合作研究了空间环境的相互作用。我们的成果致力于航天硬件和航天运行软件的开发。2D/HV于1995年5月在日本可重复使用的自由飞行平台“空间飞行者单位”（SFU）上执行。2D/HV和SFU由日本相模原操作中心（SOC）控制。日本和美国的调查人员在SOC中成功地操作2D/HV并获得飞行数据。SFU上的监控摄像机拍摄了一个序列，以便在太空中展开和收回2D/HV。日本和美国的调查人员合作分析了飞行数据，并与我们的数值模拟进行了比较。SFU于1996年1月由奋进号航天飞机回收。SFU和2D/HV是在日本进行了一年的太空飞行后首次回收到地面的飞行硬件。为了成功地执行回收任务，在1994年和1995年与美国宇航局举行了许多技术会议和讨论。2D/HV的飞行硬件在1996年作为飞行后活动进行了调查。SFU的所有飞行实验都在美国和日本进行了回顾。
