Regeneratively cooled engine tests were conducted with 80％ hydrazine-20％ MMH mixed fuels as well as with MMH single fuel, utilizing optimized injectors for each fuel. The chamber pressure was varied in a range from 0.6 to 0.9 MPa. Long duration firing tests of 160s were conducted to evaluate heat soak back level and demonstrate safe shutdowns of a mixed fuel regeneratively cooled engine. The peak specific impulses of the mixed fuel was more than 322s, while that of MMH was 308s. Regenerative cooling with the mixed fuel seemed to be particularly advantageous in that the temperature increase through the cooling channels was smaller than that of MMH; this reduced performance degradation due to reactive stream separation(′blow apart′) at higher chamber pressures. No indication of explosion in the coolant channels or manifolds at engine shutdown was observed during long firing tests of the improved chamber.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1082000","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-1082","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":"日産自動車株式会社"},{"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 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":"Nissan Motor Co., Ltd."},{"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":"植田, 修一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒田, 行郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"桜中, 登"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木皿, 且人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮島, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小坂, 勝明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長島, 隆一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UEDA, Shuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KURODA, Yukio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKURANAKA, Noboru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KISARA, Katsuto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAJIMA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOSAKA, Katsuaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGASHIMA, Ryuichi","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":"naltr01082.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01082.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45341/files/naltr01082.pdf"},"version_id":"01f59e81-fc0b-4f87-ae1f-a2898ff7e88a"}]},"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 the N2H4/MMH Mixed Fuel Regeneratively Cooled Engine","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of the N2H4/MMH Mixed Fuel Regeneratively Cooled Engine","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":"45341","relation_version_is_last":true,"title":["Performance of the N2H4/MMH Mixed Fuel Regeneratively Cooled Engine"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:41:05.802941+00:00"}
