In the development of the apogee engine for the engineering test satellite-IV(ETS-IV), the mass flow rate measurement uncertainty requirement for the propellants is less than ±0.25％, thus ensuring the overall uncertainty of the measured specific impulse is less than 1 second. The engine′s propulsion system design adopted a complete blowdown system(blowdown ratio=2:1), thus it is important to ensure the measurement accuracy for a wide range of flow rates, i.e., from about 30-120％ of the minimum flow rate(corresponding to a 0.85 MPa chamber pressure and a mixture ratio of 1.0). To achieve this uncertainty level, an \"IN-PLACE/END-TO-END\" turbine flowmeter calibration system was developed. The caliblations were conducted with actual propellants under pressures and temperatures similar to those in firing tests, thereby reducing errors caused by variations in fluid physical properties and densities. The characteristics and accuracies of the flow calibration system are described, as well as the method and results of a flow calibration using both hydrazine(N2H4) and nitrozen tetroxide(NTO). The uncertainty of the calibration factors, K-factors(pulse per unit volume), was generally estimated to be within ±0.25％ of the nominal flow rate(185cc/sec for NTO and 265cc/sec for N2H4).","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1091000","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-1091","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角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"宇宙開発事業団"},{"subitem_text_value":"石川島播磨重工業株式会社"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Research Center, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"National Space Development Agency of Japan(NASDA)"},{"subitem_text_language":"en","subitem_text_value":"Ishikawajima-Harima Heavy Industries, Co., Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"黒田, 行郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"只野, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 政裕"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"日下, 和夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮島, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長島, 隆一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 正和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KURODA, Yukio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TADANO, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SATO, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUSAKA, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAJIMA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGASHIMA, Ryuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SATO, Masakazu","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":"naltr01091.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01091.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45350/files/naltr01091.pdf"},"version_id":"854af586-a20c-4b46-b52f-40af2b25d48c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ETS-IV;  K-factors;  Flow rate Calibration;  Propellant Flow rate;  Turbine Flowmeter","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"貯蔵性推進薬実液流量較正","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"貯蔵性推進薬実液流量較正"}]},"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":"45350","relation_version_is_last":true,"title":["貯蔵性推進薬実液流量較正"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:40:58.313426+00:00"}
