The ratio of the rms values of the static pressure fluctuations measured at the test section wall to dynamic pressure values decreased from about 0.5 percent to 0.1 percent with increasing tunnel Mach number. However, the level of the static pressure fluctuations at Mach 2.0 was one order of magnitude larger than that of a high-speed in-draft wind tunnel, which is reputed to be a quiet tunnel.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063584000","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: JAXA-RM-06-013","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1121","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":"AA11983593","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部　風洞技術開発センター"},{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部　飛行システム技術開発センター"},{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部　風洞技術開発センター"},{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"IHIエアロスペース・エンジニアリング"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Wind Tunnel Technology Center, Institute of Aerospace Technology"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Flight Systems Technology Center, Institute of Aerospace Technology"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Wind Tunnel Technology Center, Institute of Aerospace Technology"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency"},{"subitem_text_language":"en","subitem_text_value":"IHI Aerospace Engineering Co.
