Incompressible, two-dimensional unsteady thin-airfoil theory is combined with an acoustic radiation model of concentrated point dipoles. The effect of duct termination is neglected. The far-field power spectral density of the associated sound is largely affected by the nature of the incoming turbulence. The effects of the turbulence scale, rotor speed, duct length and the mean flow upon the frequency spectrum and directivity are investigated in both cases of free-space and ducted-space in which \"cut-off\" and \"cut-on\" modes have coupled contributions to the radiation field.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2401420000","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_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Aeronautical Science,University of Tokyo"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0372-1418","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":"AA00675986","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KOTAKE, Susumu","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":"SA2401420.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2401420.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34567/files/SA2401420.pdf"},"version_id":"e25db9c5-0962-493c-ab88-e46bdefa0791"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Acoustic Radiation of Inlet-Turbulence/Rotor Interaction in Free and Ducted Spaces","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Acoustic Radiation of Inlet-Turbulence/Rotor Interaction in Free and Ducted Spaces","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1992"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34567","relation_version_is_last":true,"title":["Acoustic Radiation of Inlet-Turbulence/Rotor Interaction in Free and Ducted Spaces"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:39:22.585265+00:00"}
