Space debris problem is a growing concern to be tackled internationally to keep our space activity sustainable. For the improvement in the ground safety related to the survived debris after the destructive re-entry of the rocket upper stages and the spacecrafts, the comprehensive considerations on the design and the disposal operation should be made. High-fidelity model-based re-entry safety analysis tool LS-DARC is under the development in JAXA. Purpose of this study is an establishment of quantitative assessment of the design and disposal operation change effect on the re-entry risk. Consequently, a) design for demise from the initial development phase, and b) accurate risk prediction by reducing epistemic uncertainty are realized. LS-DARC is multi-physics coupling analysis code including the aerodynamic and 6DoF trajectory analysis, surface heat flux distribution analysis, three-dimensional thermal transfer analysis. Complicated real geometry can be considered including the small curvature effect on the heat flux increase and the shape change due to structure demise. Development status of LS-DARC is overviewed and the research needs are discussed.","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: AA1830034025","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":"藤本, 圭一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"根岸, 秀世"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大坊, 俊彰"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"飯塚, 宣行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"清水, 隆三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"沖田, 耕一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujimoto, Keiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Negishi, Hideyo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Daibo, Toshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iizuka, Nobuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimizu, Ryuzo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okita, Koichi","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":"AA1830034025.pdf","filesize":[{"value":"5.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830034025.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2829/files/AA1830034025.pdf"},"version_id":"b10e0ad4-d272-49a7-b263-fb2d3590ace7"}]},"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":"Development of High Fidelity Model-based Re-entry Safety Analysis Tool LS-DARC: Part 1","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of High Fidelity Model-based Re-entry Safety Analysis Tool LS-DARC: Part 1","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":"2829","relation_version_is_last":true,"title":["Development of High Fidelity Model-based Re-entry Safety Analysis Tool LS-DARC: Part 1"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:15:24.748179+00:00"}
