Consideration of the turbo-pump power balance of a staged combustion cycle engine shows that improvement in staged combustion cycle engine performance can be attained by an increase in parameter “A”, which is related to the dischange pressure of the turbo-pump; that is, A=ρ(bluk)ηpηtCpTlM(flow rate)t/M(flow rate)T. Preburner performance has been traditionally evaluated by means of C* efficiency and the spatial deviation of temperature. However, these factors do not reflect the variation of“A”and are therefore not suitable for evaluating preburner performance. Therefore, the authors define a new working index of preburner, ηw,PB and propose to use this index as a preburner performance evaluation index. The index ηw,PB is defined as the ratio of the turbine power of the actual preburner gas to the turbine power of the ideal preburner gas, that is, ηw,PB=Wt/Wt.MAX. The proposed index is shown to reflect a variation of the parameter“A”. A method to experimentally determine the index ηw,PB is also discussed.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0711000","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-711T","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"}]},"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":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田村, 洋"}],"nameIdentifiers":[{"nameIdentifier":"472270","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"若松, 義男"}],"nameIdentifiers":[{"nameIdentifier":"472271","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小野, 文衛"}],"nameIdentifiers":[{"nameIdentifier":"472272","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAMURA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472273","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"WAKAMATSU, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472274","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ONO, Fumiei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472275","nameIdentifierScheme":"WEKO"}]}]},"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":"naltr0711t.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0711t.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44968/files/naltr0711t.pdf"},"version_id":"20c1e1cb-e251-4cb5-9872-2cbbf370b207"}]},"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 Method for Preburner of Staged Combustion Cycle Engines","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance Evaluation Method for Preburner of Staged Combustion Cycle Engines","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":"44968","relation_version_is_last":true,"title":["Performance Evaluation Method for Preburner of Staged Combustion Cycle Engines"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:47:40.819253+00:00"}
