The launch vehicle will use a large LOX/LH2 engine, LE-7, which also is under development. The cryogenic propellant feed pumps of the LE-7 are characterized by large flow rate and high delivery pressure. Definition of efficiency and head of the LE-7 cryogenic pumps were required because cryogenic fluids show relatively large compressibility. The polytropic efficiency, which is used in compressors, sometimes is referred to as the true efficiency since it eliminates the effect of compressibility. An efficiency and head similar to the polytropic efficiency and head were newly defined and compared with the adiabatic efficiency and head, and it was concluded that the defined efficiency and head were fairly close to the efficiency and head of the LE-7 cryogenic pumps.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1031000","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-1031","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":"宇宙開発事業団"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"National Space Development Agency of Japan(NASDA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 誠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"上條, 謙二郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長尾, 隆治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIDA, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAMIJO, Kenjiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGAO, Ryuji","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":"naltr01031.pdf","filesize":[{"value":"540.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01031.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45290/files/naltr01031.pdf"},"version_id":"d8ff5452-6296-4587-8c3c-68d79cd05bbd"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Performance Evaluation of LE-7 High Pressure Pumps","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance Evaluation of LE-7 High Pressure Pumps","subitem_title_language":"en"}]},"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":"45290","relation_version_is_last":true,"title":["Performance Evaluation of LE-7 High Pressure Pumps"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:41:57.808257+00:00"}
