These pumps are generally driven by a hot-gas turbine, and the hot gas is usually obtained from bipropellant gas generators. The gas generator has its own problems, like hot streaking and combustion instability at an exceedingly low mixture ratio, which are different from those of the thrust chamber of a liquid rocket engine. In the present study, several kinds of Lox/Kerosene gas generators have been investigated to clearly define their performance. The major results of the present study were summarized as follows: (1)Characteristic exhaust velocity C is little influenced by any temperature distribution of hot gas at the exit of gas generators. This shows that C of gas generators is not so significant as that of thrust chambers. (2)Improvement in the temperature efficiency of gas generators must be considered in relation to their size and weight. (3)Bends better contribute to temperature uniformity at the exit of gas generators than turbulence rings or a splash ring. (4)The ratio of the pressure difference in propellant injection to the combustion chamber pressure is also an important factor in the low-frequency combustion instability of gas generators.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0642000","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-642","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":"橋本, 亮平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 義明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長谷川, 敏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIMOTO, Ryohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASEGAWA, Satoshi","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":"naltr00642.pdf","filesize":[{"value":"3.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00642.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44897/files/naltr00642.pdf"},"version_id":"6833da52-73f2-40a6-94fe-151313ec16ef"}]},"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":"An Experimental Investigation of Lox/Kerosene Gas Generators for Liquid Propellant Rockets","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Experimental Investigation of Lox/Kerosene Gas Generators for Liquid Propellant Rockets","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":"44897","relation_version_is_last":true,"title":["An Experimental Investigation of Lox/Kerosene Gas Generators for Liquid Propellant Rockets"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:48:55.739881+00:00"}
