To understand the mechanism of insect flight is important to develop Micro Air Vehicles (MAV) for rescue inquiry devices of disaster area. The aim of this investigation is a quantitative correlation analysis between vortex structure around a dragonfly and aerodynamic force. Unsteady aerodynamic force and flow field were measured by micro load-cell system and dynamic PIV system. As a result, the continuous vortex tubes were observed such as the U-shaped separation. The topology of the separated flow is almost two dimensional without near wing-tip. When the distance of vortex core was small, the large amounts of aerodynamic forces were generated. The experimental results showed strong interaction between the vortices and wings occurred when the distance of vortex core was almost same as the chord length. We also developed a mechanical flapper based on the experimental results of the flow around a dragonfly. The aerodynamic force of the mechanical flapper was proportional to the second powers of the flapping frequency. The aerodynamic lifting force of the mechanical flapper was 0.68 times of weight the flapper at the flapping frequency of 37.6 Hz. It corresponded to twice of dragonflies' weight, it therefore indicated that the mechanical flapper generated sufficiently large enough to lift of dragonflies.","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: AA0064237019","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":"豊橋技術科学大学機械システム工学系"},{"subitem_text_value":"工学院大学工学部機械工学科"},{"subitem_text_value":"工学院大学工学部機械工学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Toyohashi University of Technology"},{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Faculty of Engineering, Kogakuin University"},{"subitem_text_language":"en","subitem_text_value":"Department of Mechanical Engineering, Faculty of Engineering, Kogakuin University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"飯田, 明由"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荻巣, 宏幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"冨川, 昌義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iida, Akiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogisu, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukawa, Masayoshi","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":"64237019.pdf","filesize":[{"value":"905.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64237019.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5477/files/64237019.pdf"},"version_id":"77f99fcc-198a-4212-b2cd-da9d8a1fc492"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Unsteady flow, Vortex structures, MAV, PIV, Biomimetics","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":"羽ばたき翼周りの非定常流れと発生する流体力の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"羽ばたき翼周りの非定常流れと発生する流体力の関係"}]},"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":"5477","relation_version_is_last":true,"title":["羽ばたき翼周りの非定常流れと発生する流体力の関係"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:14:12.951654+00:00"}
