Very long period fluctuations of these pressures occur and it had been thought that such changes did not exert a significant influence on Mach number measurement. However, the pressure measurement systems employed very long tubes and it transpired that the phase difference between two measured pressures made the Mach numbers fluctuate. Consequently, the pipes having an optimal length and the inner diameter were designed and installed. To carry out this optimization, a computer program was developed that is capable of computing the response characteristics of pressure measurement systems without flow. The source code of the program is appended to the end of the report.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049201000","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-RR-05-037","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":"1349-1113","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":"AA1192675X","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　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　風洞技術開発センター"},{"subitem_text_value":"コスモテック"},{"subitem_text_value":"コスモテック"}]},"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 Wind Tunnel 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":"Cosmotec Co.
