So, it is desirable that a propellant tank would demise. Since 2010, JAXA conducted research to develop an aluminum-lined, carbon composite overwrapped tank for reducing impact risk to the ground. In the early phase, it expected that the resin of CFRP would decomposed by aerodynamic heat and residual carbon fibers were blown away by the effect of airflow. However, JAXA started reevaluation of the survivability of this composite propellant tank when debris mitigation study in JAXA was reorganized at 2016. This year, we conducted arc wind tunnel tests of material samples which were cut off from the EM tank. We report test results and current reevaluation status.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_4_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830034053","subitem_description_type":"Other"}]},"item_4_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-18-011","subitem_description_type":"Other"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"清水, 隆三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"池田, 博英"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤本, 圭一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"足立, 寛和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 純"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"畑井, 啓吾"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimizu, Ryuzo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikeda, Hirohide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujimoto, Keiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Adachi, Hirokazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsumoto, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hatai, Keigo","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1830034053.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830034053.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2857/files/AA1830034053.pdf"},"version_id":"46c61022-a9cc-4f4d-a088-b6ea32fa721d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Evaluation Status of Re-entry Survivability of Spacecraft Composite Propellant Tank","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation Status of Re-entry Survivability of Spacecraft Composite Propellant Tank","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["795","1502","1828","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-15"},"publish_date":"2019-03-15","publish_status":"0","recid":"2857","relation_version_is_last":true,"title":["Evaluation Status of Re-entry Survivability of Spacecraft Composite Propellant Tank"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:14:56.775766+00:00"}
