Because of the velocity on the order of kilometers/second, the reaction zone is relatively small. Therefore, the RDE realizes a short combustion chamber length. However, the detonation waves induce an azimuthal motion of propellant, resulting in torque around the thrust axis. Because the motion does not contribute to the thrust, the torque is important in terms of performance loss. Herein, we conducted combustion tests with a six-axis force sensor to simultaneously measure 0.149±0.009  Nm torque and 48.1±0.9  N thrust. A comparison of detonation waves captured by high-speed camera revealed that the torque followed the direction and was offset when the waves existed in both of two directions simultaneously, which indicates the possibility of controlling the torque. Under a mass flow rate at 87±9  g/s and an equivalence ratio at 1.43±0.28, when the azimuthal component of shear force was 8.8±0.6% of the thrust, 0.77±0.10% of the total kinetic energy of the exit flow was distributed to the azimuthal component of velocity and did not contribute to the thrust. We therefore concluded that the effect of the azimuthal motion on the RDE’s performance was small.", "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.B38374", "subitem_relation_type_select": "DOI"}}]}, "item_9_source_id_7": {"attribute_name": "収録物識別子", "attribute_value_mlt": [{"subitem_source_identifier": "1533-3876", "subitem_source_identifier_type": "EISSN"}]}, "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": "Sawada, Satoru", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Goto, Keisuke", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ishihara, Kazuki", "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"}]}]}, "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": "20210703_JPP_manuscript_forRepository.pdf", "filesize": [{"value": "3.6 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "application/pdf", "size": 3600000.0, "url": {"objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/2003923/files/20210703_JPP_manuscript_forRepository.pdf"}, "version_id": "606574b9-1c11-4a8d-9620-4f59f6780653"}]}, "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": "Torque Around Axial Direction on Rotating Detonation Engines", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Torque Around Axial Direction on Rotating Detonation Engines", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "17", "path": ["675"], "permalink_uri": "http://hdl.handle.net/2237/0002003923", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-10-13"}, "publish_date": "2022-10-13", "publish_status": "0", "recid": "2003923", "relation": {}, "relation_version_is_last": true, "title": ["Torque Around Axial Direction on Rotating Detonation Engines"], "weko_shared_id": -1}
