However, there are many technical issues associated with such vehicles, such as turnover maneuvers during return flight where the pitching moment plays a key role. It is known that aerodynamic characteristics can be controlled by installing aerodynamic devices, but the relationship between the aerodynamic characteristics and the flowfields has not been explored. To clarify this relationship using computational fluid dynamics (CFD), we investigated these flowfields and aerodynamic characteristics, in the case where we install such devices (fins) in the nose part of a reusable rocket. We found that vortices form downstream of the aerodynamic devices. For angles of attack between 0 and 90 degrees (in which the fins are located in the upstream portion), these vortices significantly affect the surface pressure on the rocket and increase the pitching moment. On the other hand, for AOAs between 90 to 180 degrees (in which the fins are in the downstream portion), the effect of these vortices on the on-surface pressure is negligible, and only vortices formed near the surface of the fins increase the pitching moment.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"JSASS"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.2322/tastj.17.104","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18840485","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Institute of Space and Astronautical Science, JAXA"}]},"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_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Aogaki, Takuya"}],"nameIdentifiers":[{"nameIdentifier":"35866","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":"35864","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40332150","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40332150"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-06-17"}],"displaytype":"detail","filename":"advpub_17.104.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"advpub_17.104.pdf","url":"https://ynu.repo.nii.ac.jp/record/9976/files/advpub_17.104.pdf"},"version_id":"af087aee-43d8-4131-bbf9-aba4111ecfda"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Reusable Rocket","subitem_subject_scheme":"Other"},{"subitem_subject":"Fin","subitem_subject_scheme":"Other"},{"subitem_subject":"High Angle of Attack","subitem_subject_scheme":"Other"}]},"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":"Computational Study on Finned Reusable Rocket Aerodynamics during Turnover","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Computational Study on Finned Reusable Rocket Aerodynamics during Turnover"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-06-17"},"publish_date":"2019-06-17","publish_status":"0","recid":"9976","relation_version_is_last":true,"title":["Computational Study on Finned Reusable Rocket Aerodynamics during Turnover"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T19:00:31.375411+00:00"}
