Far-field sound pressure levels (at a distance of SOm from the engine) andengine performance data were obtained to evaluate the performance of the test configurations. Sound power attenuation spectra for treated inlet-duct configurations were shown by an insertion loss technique. For frequencies above peak, the observed attenuations were more than predicted. The effects of SjA (the ratio of treated surface area to duct cross sectional area) on sound powei attenuation were also presented for one-third octave band center frequency 4KHz.  The increase of a noise floor due to forward radiated jet noise was observed with the increase of the engine speeds.  The performance of the treated jet pipe could not be evaluated by one-third octave band analysis adopted here.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTM0271000","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 TM-271","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":"0452-2982","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00314334","subitem_source_identifier_type":"NCID"}]},"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鳥崎, 忠雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 実"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小林, 紘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"武田, 克巳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TORISAKI, Tadao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOBAYASHI, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEDA, Katsumi","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":"2020-01-28"}],"displaytype":"detail","filename":"naltm00271.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltm00271.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43854/files/naltm00271.pdf"},"version_id":"35b10e02-084c-4570-8a38-01e9cb7f6565"}]},"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":"ジェットエンジン低騒音化の研究: 第二報JR100H-1Pを用いたジェットエンジン消音の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ジェットエンジン低騒音化の研究: 第二報JR100H-1Pを用いたジェットエンジン消音の研究"}]},"item_type_id":"3","owner":"1","path":["1893","1916"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43854","relation_version_is_last":true,"title":["ジェットエンジン低騒音化の研究: 第二報JR100H-1Pを用いたジェットエンジン消音の研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:06:46.056644+00:00"}
