A distinctive feature of the molding method is the introduction of a copper coated wax core which forms a three-dimensional hollow shape inside a model. The air cooled turbine photoelastic model with a coolant passage simulates the first stage rotor blade in the high temperature turbine full scale model HT-10H used at the NAL. The results of stress analysis cleared the critical regions and stress magnitude and thus they are of great aid to the successful development of a full scale turbine model.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0427T000","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-427T","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原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"}]},"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":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 豊明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松末, 勝利"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高原, 北雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋本, 良作"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIDA, Toyoaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUSUE, Katsutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHARA, Kitao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIMOTO, Ryosaku","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":"naltr0427t.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0427t.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44677/files/naltr0427t.pdf"},"version_id":"a33f8f54-ffbb-44f2-98f5-225fe1b12e51"}]},"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":"New Molding Method of Three-Dimensional Hollow Photoelastic Model and Centrifugal Stress Analysis of Air Cooled Turbine Blade Model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"New Molding Method of Three-Dimensional Hollow Photoelastic Model and Centrifugal Stress Analysis of Air Cooled Turbine Blade Model","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":"44677","relation_version_is_last":true,"title":["New Molding Method of Three-Dimensional Hollow Photoelastic Model and Centrifugal Stress Analysis of Air Cooled Turbine Blade Model"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:52:48.549809+00:00"}
