The fans are considered to be double circular-arc blades, hollowed 30% and twisted by a component of the centrifugal force at the rated revolution. There are 0-7 webs inserted in the hollow section. The following became clear after stress and rigidity analysis of the hollow blades. 1)Making the fan blade hollow by 30% increases the torsional rigidity per cross section by 20-24%, and maximum shear stress by 17-27%. 2)The number and location of webs don't have a considerable effect on torsional rigidity. 3)There is an optimum web location for torsional rigidity, where the shear strain in webs is maximum. 4)Shear flows branch away to webs, and stress consentrations decrease.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0533000","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-533","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原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所計算センター"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Computer Center, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小河, 昭紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"祖父江, 靖"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"磯部, 俊夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGAWA, Akinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SOFUE, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ISOBE, Toshio","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":"naltr00533.pdf","filesize":[{"value":"867.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00533.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44787/files/naltr00533.pdf"},"version_id":"b519bc85-b880-4301-8609-278d063baa2f"}]},"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":"中空翼の構造解析-ファン動翼のねじり応力解析-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中空翼の構造解析-ファン動翼のねじり応力解析-"}]},"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":"44787","relation_version_is_last":true,"title":["中空翼の構造解析-ファン動翼のねじり応力解析-"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:50:55.175144+00:00"}
