This report provides the overview of the tool development and the result of the validation including a prediction of the take-off and landing noise of the A320-232 aircraft. The difference between the prediction of A320-232 and its certificated noise level was less than 3 EPNdB. It is expected that the proposed tool allows the planning of noise reduction in conceptual study of future aircraft.","subitem_description_type":"Other"}]},"item_3_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_3_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_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1630034000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RR-16-005","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/JAXA-RR-16-005/0001","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1113","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空技術部門次世代航空イノベーションハブ(JAXA)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Next Generation Aeronautical Innovation Hub Center, Aeronautical Technology Directorate, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"赤塚, 純一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akatsuka, Junichi","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":"2020-01-31"}],"displaytype":"detail","filename":"AA1630034000.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1630034000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1874/files/AA1630034000.pdf"},"version_id":"b3ae4a4e-2be8-4536-960c-266bc2e58265"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Take-off","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Landing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Estimation","subitem_subject_language":"en","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"航空機の離着陸騒音推算ツール(AiNEST)の構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"航空機の離着陸騒音推算ツール(AiNEST)の構築"}]},"item_type_id":"3","owner":"1","path":["49","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-02-08"},"publish_date":"2017-02-08","publish_status":"0","recid":"1874","relation_version_is_last":true,"title":["航空機の離着陸騒音推算ツール(AiNEST)の構築"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:37:38.162676+00:00"}
