The notch, a tiny dent formed at the nozzle lip, is expected to suppress both jet mixing noise and thrust loss due to the mixing enhancement. Authors have continued research and development on this mixing device through experimental and computational approaches. As a result, a revised version of the notched nozzle, 18-notch, was proposed and tested in the model tests under cold and hot conditions. An experimental validation with the larger-scale 18-notched nozzle was then conducted using a turbo-jet engine. This paper outlines the noise test setup with this engine and the test results. The newly proposed notched nozzle showed the improvement in noise radiation characteristics and provided a potential reduction in effective perceived noise level as much as 1 dB compared to the baseline conical nozzle.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1420050000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本ガスタービン学会(GTSJ)"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Gas Turbine Society of Japan (GTSJ)"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-4168","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00186926","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"株式会社IHI"},{"subitem_text_value":"株式会社IHI"},{"subitem_text_value":"ブリュエル・ケアー・ジャパン"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"IHI Corporation"},{"subitem_text_language":"en","subitem_text_value":"IHI Corporation"},{"subitem_text_language":"en","subitem_text_value":"Bruel & Kjaer Division, Spectris Co."}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石井, 達哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 望"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大石, 勉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石井, 豊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Nozomi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oishi, Tsutomu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Yutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ノッチ","subitem_subject_scheme":"Other"},{"subitem_subject":"ジェットエンジン","subitem_subject_scheme":"Other"},{"subitem_subject":"ジェット混合騒音","subitem_subject_scheme":"Other"},{"subitem_subject":"騒音試験","subitem_subject_scheme":"Other"},{"subitem_subject":"実効感覚騒音レベル","subitem_subject_scheme":"Other"},{"subitem_subject":"Active Noise Cancellation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fan Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Duct Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mode Decomposition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Filtered-x LMS Algorithm","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ノッチノズルのエンジン騒音試験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ノッチノズルのエンジン騒音試験"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"22495","relation_version_is_last":true,"title":["ノッチノズルのエンジン騒音試験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:20:11.920176+00:00"}
