In this study, we focused on the acceleration of subsonic burned gas without a structural throat via detonation to realize a simple and compact engine. We developed and tested a rotating detonation engine (RDE) without a throat and with a diverging channel (constant diverging angle α=5  deg). Gaseous C2H4 and O2 were used as the propellants, and the mass flow rate ranged from 62 to 134  g/s in the combustion tests under low back-pressure conditions. We measured pressure and thrust, as well as high-speed imaging of self-luminescence of the combustion and imaging of the exhaust plume. The pressure at the exit was less than one-fifth of the maximum pressure in the RDE, significantly below the value for a sonic flow. The results suggested that the exhaust flow was supersonic, with values up to Mach 1.7, without the need of a converging section within the engine. In addition to the estimated Mach number from the measured pressure, the exhaust plume images coherently indicated the existence of supersonic exhaust.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Aeronautics and Astronautics", "subitem_publisher_language": "en"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.2514/1.J061300", "subitem_relation_type_select": "DOI"}}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "0001-1452", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Nakata, Kotaro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ota, Kosei", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ito, Shiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ishihara, Kazuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Goto, Keisuke", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Itouyama, Noboru", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Watanabe, Hiroaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kawasaki, Akira", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Matsuoka, Ken", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kasahara, Jiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Matsuo, Akiko", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Funaki, Ikkoh", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Higashino, Kazuyuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Braun, James", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Meyer, Terrence", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Paniagua, Guillermo", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-10-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "AIAAJournal_revision_without_correction_footnote_forRepository.pdf", "filesize": [{"value": "3.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 3800000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2003924/files/AIAAJournal_revision_without_correction_footnote_forRepository.pdf"}, "version_id": "46190099-3172-40c5-a360-82d8e547146c"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Supersonic Exhaust from a Rotating Detonation Engine with Throatless Diverging Channel", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Supersonic Exhaust from a Rotating Detonation Engine with Throatless Diverging Channel", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "17", "path": ["675"], "permalink_uri": "http://hdl.handle.net/2237/0002003924", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-10-13"}, "publish_date": "2022-10-13", "publish_status": "0", "recid": "2003924", "relation": {}, "relation_version_is_last": true, "title": ["Supersonic Exhaust from a Rotating Detonation Engine with Throatless Diverging Channel"], "weko_shared_id": -1}
