In order to identify the test section wall slot effects, the following measurements were made ; keeping the side wall slot (for wake survey probe trav..) open measurements were mede with the transonic slots (top and bottom walls) both open and closed ; then, conversely, keeping the transonic slots open measurements were made with the side wall slot open and closed. The pressure fluctuations of the flow at these locations in the wind tunnel were measured by means of wall or sting-mounted ultra miniature pressure sensors. The data, which represented a frequency range from about 15 Hz to 25 kHz, have been analyzed in the form of broadband sound pressure levels, root-mean-square fluctuations of pressure coefficient and spectra of pressure fluctuations. There is a brief discussion of each item. R.m.s.and spectra of pressure fluctuations at the test section, which were compared with other wind tunnels, have been considered moderate in the transonic regime (0.7 < M < 0.9).","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0836000","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-836","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空気力学第二部"},{"subitem_text_value":"航空宇宙技術研究所空気力学第二部"},{"subitem_text_value":"航空宇宙技術研究所空気力学第二部"},{"subitem_text_value":"航空宇宙技術研究所空気力学第二部"},{"subitem_text_value":"航空宇宙技術研究所空気力学第二部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Second Aerodynamics Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"榊原, 盛三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三輪, 等"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小国, 保男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 衛"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神田, 宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKAKIBARA, Seizo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIWA, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGUNI, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SATO, Mamoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANDA, Hiroshi","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":"naltr00836.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00836.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45094/files/naltr00836.pdf"},"version_id":"ae4818a6-6c69-449a-a3be-c6e7bb883064"}]},"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":"航技研二次元風胴の気流特性について(Ⅱ)-風胴各部の変動圧力(騒音)の分析と音源の検討-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"航技研二次元風胴の気流特性について(Ⅱ)-風胴各部の変動圧力(騒音)の分析と音源の検討-"}]},"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":"45094","relation_version_is_last":true,"title":["航技研二次元風胴の気流特性について(Ⅱ)-風胴各部の変動圧力(騒音)の分析と音源の検討-"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:45:23.211364+00:00"}
