Aerodynamic loads generated by a blade are calculated by solving the three-dimensional Euler equations in a rotating coordinate system on body-conforming curvilinear grids around a blade. These equations are solved by employing Beam-Warming scheme and TVD scheme is used in order to capture the accurate shock wave. The local induced velocity generated by the rotor-wake is taken into the calculation by subtracting the equivalent angle of attack along the blade from the geometrical one. This equivalent angle of attack is calculated by using prescribed-wake vortex theory. The ability of the present method is verified in comparison with the results of the experiment and the analytical method. In addition, the effects of the planforms of a blade tip on the performance of a helicopter rotor and on the flow around a blade in hover are analyzed. The comparison among swept-back, tapered and swept-back tapered tips is presented. As a result,one tip planform, which has sweep-back angle and inverse-taper, is found to improve the performance of the rotor.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0010042","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 SP-10","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":"0289-260X","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":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学工学部航空学科"},{"subitem_text_value":"東京大学先端科学技術研究センター"},{"subitem_text_value":"航空宇宙技術研究所"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"青山, 剛史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河内, 啓二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"齊藤, 茂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoyama, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawachi, Keiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saito, Shigeru","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":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0010042.pdf","filesize":[{"value":"412.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0010042.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43371/files/nalsp0010042.pdf"},"version_id":"f3cc3911-f030-4b54-a0f4-600aad2de37b"}]},"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":"ホバリング・ロータに及ぼす翼端形状の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ホバリング・ロータに及ぼす翼端形状の影響"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43371","relation_version_is_last":true,"title":["ホバリング・ロータに及ぼす翼端形状の影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:16:18.391584+00:00"}
