The most used numerical method that is employed for flutter prediction is the energy method. Although a lot of papers are devoted to the analysis of different blade wheels, this method was rarely validated by experiments. Typical mesh size, time step, and various modeling approaches that guarantee reliable flutter prediction are not commonly known, whereas some examples show that predictions obtained through nonvalidated codes can be inaccurate. In this paper, we describe the implementation of the energy method that is employed in the design of jet engines and gas turbines in Gas Turbine Engineering Research and Production Center “Salut”. Flutter onset predictions are obtained for two wheel models representing two stages of the same compressor. For the model of a blade wheel, blade oscillations in a natural mode are specified and unsteady aerodynamic analysis is conducted. Then the work done by unsteady pressure over the oscillation cycle is calculated, and based on its sign the flutter prediction is made. Numerical results are verified by compressor and full engine flutter test data. Tests were conducted in two operating regimes: stable and flutter. It is shown that the prediction of flutter onset is rather reliable so that the modeling approaches presented in this paper can be used by other researchers for the flutter analysis of industrial compressor and turbine blades.","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_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1630046046","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-16-008E","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(JAXA)"}]},"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_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Lomonosov Moscow State University"},{"subitem_text_language":"en","subitem_text_value":"Gas Turbine Engineering Research and Production Center “Salut”"},{"subitem_text_language":"en","subitem_text_value":"Lomonosov Moscow State University"},{"subitem_text_language":"en","subitem_text_value":"Lomonosov Moscow State University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kolotnikov, Mikhail","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13616","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makarov, Pavel","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13617","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Abdukhakimov, Farrukh","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13618","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Vedeneev, Vasily","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"13619","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1630046046.pdf","filesize":[{"value":"983.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1630046046.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3439/files/AA1630046046.pdf"},"version_id":"6fe03dff-22ad-49eb-a6dc-1aba58c77acd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"blade flutter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"jet engines","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gas turbines","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Flutter prediction in modern aircraft engines and gas turbines","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Flutter prediction in modern aircraft engines and gas turbines","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["824","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-27"},"publish_date":"2017-04-27","publish_status":"0","recid":"3439","relation_version_is_last":true,"title":["Flutter prediction in modern aircraft engines and gas turbines"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:02:17.260846+00:00"}
