Although studies have been made previously [1], [2] for PHASE 1 (in which the wire is changing in length and is tangent to the satellite), there has been little effort to analyze the three-dimensional motion of the yo-yo in PHASE 2 (in which the length of wire is constant but its position is changing from tangent to perpendicular to the satellite). This study considers the motion of the rigid yo-yo in PHASE 1 and PHASE 2 as a three-dimensional problem and the equations of motion of the system which is derived are solved numerically for several specific cases. The results show that this theory is a sufficient to make clear the motion of the rigid yo-yo in PHASE 1 and PHASE 2. Then some results of the stretch yo-yo feasibility tests are presented. These tests were conducted to prove the concept that the stretch yo-yo is a more accurate despin device than the rigid yo-yo, and to verify the analytical theory. The results of another experiment which was conducted on the rigid yo-yo are also presented. In this case, yo-yo wires were wound around an octogonal cylinder to compare with the case in which yo-yo wires are wound around a right cylinder.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125383000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","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":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"}]},"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 Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeroautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"上杉, 邦憲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"二宮, 敬虔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大西, 晃"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UESUGI, Kuninori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NINOMIYA, Keiken","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ONISHI, Akira","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":"SA0125383.pdf","filesize":[{"value":"904.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125383.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32227/files/SA0125383.pdf"},"version_id":"97ee90a3-f869-4301-9563-188a729245a4"}]},"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":"ヨーヨー・デスピン(II)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヨーヨー・デスピン(II)"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32227","relation_version_is_last":true,"title":["ヨーヨー・デスピン(II)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:38:01.758450+00:00"}
