However, there are many technical issues associated with such vehicles, such as the safe execution of a turnover maneuver during return flight. It is known that a relatively desirable pitching moment characteristic for turnover can be accomplished by employing a slender-body configuration, but the reason for this is not well understood. In this study, a delayed detached-eddy simulation on the aerodynamic characteristics of such a slender-bodied reusable rocket is carried out for angles of attack between 0 and 180 deg using unstructured compressible computational fluid dynamics. Inviscid calculations are also conducted to distinguish the pitching moment contribution of the body configuration itself from the effects of viscosity and turbulence. It was found that two types of vortices were formed at 0–90 deg, and these vortices affected the pitching moment distribution. Three types of vortices generated at 90–180 deg were also observed. Combined with the results of the inviscid simulation, it is concluded that the pitching moment characteristic is greatly impacted by the behaviors of these vortices and bubbles.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_35": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Institute of Aeronautics and Astronautics"}]}, "item_2_relation_13": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.2514/1.A34211", "subitem_relation_type_select": "DOI"}}]}, "item_2_rights_14": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2018 by the American Institute of Aeronautics and Astronautics, Inc."}]}, "item_2_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00224650", "subitem_source_identifier_type": "ISSN"}]}, "item_2_text_4": {"attribute_name": "著者所属", "attribute_value_mlt": [{"subitem_text_value": "Graduate Student, Graduate School of Engineering, Yokohama National University"}, {"subitem_text_value": "Associate Professor, Graduate School of Engineering, Yokohama National University"}, {"subitem_text_value": "Associate Professor, JAXA, Institute of Space and Astronautical Science"}]}, "item_2_version_type_18": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_ab4af688f83e57aa", "subitem_version_type": "AM"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Aogaki, Takuya"}], "nameIdentifiers": [{"nameIdentifier": "34973", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kitamura, Keiichi"}], "nameIdentifiers": [{"nameIdentifier": "34964", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "20402547", "nameIdentifierScheme": "e-Rad", "nameIdentifierURI": "https://kaken.nii.ac.jp/ja/search/?qm=20402547"}]}, {"creatorNames": [{"creatorName": "Nonaka, Satoshi"}], "nameIdentifiers": [{"nameIdentifier": "34974", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-01-25"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Journal_aogaki.pdf", "filesize": [{"value": "3.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3300000.0, "url": {"label": "Journal_aogaki.pdf", "url": "https://ynu.repo.nii.ac.jp/record/9456/files/Journal_aogaki.pdf"}, "version_id": "ba24de3e-c667-4ae5-aae0-83be30110703"}]}, "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": "Numerical Study on High Angle-of-Attack Pitching Moment Characteristics of Slender-Bodied Reusable Rocket", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Numerical Study on High Angle-of-Attack Pitching Moment Characteristics of Slender-Bodied Reusable Rocket"}]}, "item_type_id": "2", "owner": "17", "path": ["496"], "permalink_uri": "http://hdl.handle.net/10131/00012125", "pubdate": {"attribute_name": "公開日", "attribute_value": "2019-01-25"}, "publish_date": "2019-01-25", "publish_status": "0", "recid": "9456", "relation": {}, "relation_version_is_last": true, "title": ["Numerical Study on High Angle-of-Attack Pitching Moment Characteristics of Slender-Bodied Reusable Rocket"], "weko_shared_id": -1}
