The objective of the study was to examine the effects of rocket chamber pressure, Pc and second fuel injection on the engine performance and related flow physics before the engine combustion tests. The calculation results revealed that the engine produced higher specific impulse as well as thrust with higher Pc; however, the thrust gain could hardly exceed the embedded rocket thrust. This is due to the fact that the rocket exhaust increased the friction drag on the combustor walls over the thrust due to combustion with the captured air and momentum addition of the rocket flow. On the other hand, the second fuel injection in the diverging combustor had almost no impact on the thrust augmentation even at low Pc conditions with a large amount of second fuel, resulting in \"\" reduction of the specific impulse contrary to expectations. This partially came from that at lower Pc the combustion efficiency was reduced because of the lower temperature and larger amount of H radical production as well as poorer fuel/air mixing.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0061958023","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-12-010","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構宇宙輸送系推進技術研究開発センター先進技術研究グループ(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構宇宙輸送系推進技術研究開発センター先進技術研究グループ(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構宇宙輸送系推進技術研究開発センター先進技術研究グループ(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構宇宙輸送系推進技術研究開発センター先進技術研究グループ(JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Advanced Propulsion Technology Research Group, Space Transporｔation Propulsion Research and Development Center, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Advanced Propulsion Technology Research Group, Space Transporｔation Propulsion Research and Development Center, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Advanced Propulsion Technology Research Group, Space Transporｔation Propulsion Research and Development Center, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Advanced Propulsion Technology Research Group, Space Transporｔation Propulsion Research and Development Center, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小寺, 正敏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"富岡, 定毅"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"植田, 修一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷, 香一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kodera, Masatoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomioka, Sadatake","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ueda, Shuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tani, Kouichiro","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":"2020-01-16"}],"displaytype":"detail","filename":"61958023.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"61958023.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4263/files/61958023.pdf"},"version_id":"be75a7fe-72f8-4ed4-8900-c38d74f7e8b6"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"スクラムジェットモードにおけるロケット: ラムジェット複合エンジンの数値計算","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スクラムジェットモードにおけるロケット: ラムジェット複合エンジンの数値計算"}]},"item_type_id":"5","owner":"1","path":["896","1537","1881","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4263","relation_version_is_last":true,"title":["スクラムジェットモードにおけるロケット: ラムジェット複合エンジンの数値計算"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:43:41.928256+00:00"}
