The splitter plate is placed at the trailing-edge of the airfoil to produce the no sound emitted condition. At this condition, the instability wave with broad band spectrum which central frequency almost coincides the tonal noise frequency is clearly observed on the pressure side. The artificial acoustic disturbances which are the feedback of the instability wave on the airfoil are introduced at no sound emitted condition, and it is observed that the broad-band spectrum become discrete soon after the feedback is excited. These results confirmed that the trailing-edge noise is the consequence of the acoustic feedback loop between a vortex shedding at the trailing edge and an instability wave on the pressure side of the airfoil.","subitem_description_type":"Other"}]},"item_5_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_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064237013","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-08-006","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構総合技術研究本部"},{"subitem_text_value":"宇宙航空研究開発機構総合技術研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Aerospace Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aerospace Technology, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高木, 正平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小西, 康郁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takagi, Shohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Konishi, Yasufumi","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":"2020-01-16"}],"displaytype":"detail","filename":"64237013.pdf","filesize":[{"value":"628.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64237013.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5471/files/64237013.pdf"},"version_id":"70a460e5-0502-4121-8ed7-549420ff19ab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"trailing-edge noise, boundary layer instability, acoustic feedback loop","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"二次元翼後縁騒音の周波数選択機構に関する実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二次元翼後縁騒音の周波数選択機構に関する実験"}]},"item_type_id":"5","owner":"1","path":["967","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5471","relation_version_is_last":true,"title":["二次元翼後縁騒音の周波数選択機構に関する実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:14:24.444016+00:00"}
