And a solar thermal propusion system, a kind of gas jet engine, has been studied. Large expansion area engines have been studied to achieve high specific impulse, Isp. If external energy is added to an engine, Isp can be better than the theoretical Isp based on tank level enthalpy. In this report, solar energy was used as the additional energy supplied to a rocket engine. The LH2/LO2 expander cycle engine with a solar heat exchanger was studied. This engine has two merits. One is the increase of Isp, which allows a greater payload to be carried by a rocket with the solar heat exchanger than by a normal rocket. The other merit is a cycle pressure level decrease. The Isp increase is realized for every engine and for every propellant, if additional energy is available.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0992000","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-992","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宇宙研究グループ"},{"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":"Space Technology Research Group, 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":"苅田, 丈士"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"若松, 義男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"冠, 昭夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANDA, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WAKAMATSU, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANMURI, Akio","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":"naltr00992.pdf","filesize":[{"value":"943.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00992.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45251/files/naltr00992.pdf"},"version_id":"4045fb91-45d7-4a82-80a4-35527b48a74e"}]},"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":"LH2/LO2 Rocket Engine with Solar Energy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LH2/LO2 Rocket Engine with Solar Energy","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":"45251","relation_version_is_last":true,"title":["LH2/LO2 Rocket Engine with Solar Energy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:42:40.710433+00:00"}
