Considering the frequency, condition of microgravity environment, and expenses, an inexpensive means with longer duration of microgravity than by an airplane or a drop type facility is expected. In 1980s three scientific balloons were launched with microgravity capsules which were dropped in the stratosphere to make a microgravity environment of 0.01g for 18 seconds. A long duration (more than 30 seconds) will be useful for such type of microgravity experiments. The conditions of duration, microgravity level, and experimental units loaded in a microgravity capsule were obtained by numerical simulations for free-fall capsules using the results of wind tunnel tests and the real condition of the upper air and wind over Sanriku Balloon Center. The results show that a microgravity experimental unit with 0.4m in diameter and 40kg in weight can make a 0.01g-microgravity environment for 30 seconds while a 0.125m and 10kg one can last for 35 to 40 seconds.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0167141000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井筒, 直樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"稲富, 裕光"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"並木, 道義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"栗林, 一彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢島, 信之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IZUTSU, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"INATOMI, Yuko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAMIKI, Michiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KURIBAYASHI, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAJIMA, Nobuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0167141.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0167141.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33212/files/SA0167141.pdf"},"version_id":"a5d84c35-4f4b-4e44-a150-9d02e296a47f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"気球実験","subitem_subject_scheme":"Other"},{"subitem_subject":"微小重力","subitem_subject_scheme":"Other"},{"subitem_subject":"風洞試験","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"微小重力実験用落下カプセルの風洞試験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"微小重力実験用落下カプセルの風洞試験"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33212","relation_version_is_last":true,"title":["微小重力実験用落下カプセルの風洞試験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:12:40.621696+00:00"}
