Under no incoming-flow conditions, the blade separated flow was also discussed from on academic point of view. The data for the advance ratio of 0.43-1.15 were obtained in the aeroacoustic aspects. The altermately swept blades arrangement showed the best performance in spanwise load distribution among the three configurations. The forward-swept blades did not exhibit any aeroacoustic advantage. The altermately swept configuration as a tandem rotation has the potential for decreasing the sound levels at the blade passage frequencies by the dispersion of sound with no sacrifice of aerodynamic performance and no additional mechanical complexity.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0935000","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: NAL TR-935","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所新型航空機研究グループ"},{"subitem_text_value":"航空宇宙技術研究所新型航空機研究グループ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"V/STOL Aircraft Research Group, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"V/STOL Aircraft Research Group, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西脇, 英夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"武田, 克巳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NISHIWAKI, Hideo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEDA, Katsumi","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00935.pdf","filesize":[{"value":"999.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00935.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45194/files/naltr00935.pdf"},"version_id":"2fc515be-2694-4d75-a0c8-159bcdc5fda6"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Aerodynamic and Acoustic Characteristics of an Advanced Propeller under Take-off and Landing Conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Aerodynamic and Acoustic Characteristics of an Advanced Propeller under Take-off and Landing Conditions","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45194","relation_version_is_last":true,"title":["Aerodynamic and Acoustic Characteristics of an Advanced Propeller under Take-off and Landing Conditions"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:43:38.215463+00:00"}
