These pumps were made for use with liquid oxygen (LOX) and liquid hydrogen (LH2) feed pumps. They have very small impellers and are characterized by high speed and high head. The main design characteristics of these pumps are as follows: stage specific speeds of from 0.0319 to 0.0766, flow rates from 0.016 to 0.0525 m3/s, pressure rises from 4.9 to 26 MPa, rotational speeds from 16,500 to 80,000 rpm and impeller diameters from 0.083 to 0.146 m. These pumps were tested using water, LOX, liquid nitrogen (LN2) and liquid hydrogen as the pump fluids. The present paper not only focuses on overall performance factors such as efficiency and head/flow characteristics, but also on suction performance of these pumps.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0963000","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-963","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":"渡辺, 義明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 光男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"上條, 謙二郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Mitsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAMIJO, Kenjiro","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":"naltr00963.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00963.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45222/files/naltr00963.pdf"},"version_id":"227647f2-03e8-4949-b6db-732ffc81738f"}]},"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 of Small High Speed Rocket Pumps","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of Small High Speed Rocket 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":"45222","relation_version_is_last":true,"title":["Performance of Small High Speed Rocket Pumps"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:43:06.685565+00:00"}
