Thus, it is important in rocket development to clarify the effects of the protuberances on the vehicle aerodynamic characteristics. In this study, as a basic research, we systematically investigated such effects using CFD, by changing the positions of a protuberance. As a result, the roll moment increased nearly linearly with angle of attack (=α), but its trend was different in protuberance locations, particularly when arranged near the center-of-gravity. In positioning there at α = 20 °, the wake vortex center moved farther away from protuberance compared with α = 15 °, then the pressure decline at its wake side was suppressed, and thus, the pressure difference between its upstream and downstream sides became smaller. As a consequence, the roll moment did not arise linearly, but decreased at α = 20 °.","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.17.111","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":"Department of System Integration, Yokohama National University"},{"subitem_text_value":"Department of System Integration, 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":"Harada, Toshiaki"}],"nameIdentifiers":[{"nameIdentifier":"35867","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_17.111.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"advpub_17.111.pdf","url":"https://ynu.repo.nii.ac.jp/record/9977/files/advpub_17.111.pdf"},"version_id":"77bfcc8b-ad0f-43c3-86af-0f537fa8cd0f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Aerodynamics","subitem_subject_scheme":"Other"},{"subitem_subject":"Rockets","subitem_subject_scheme":"Other"},{"subitem_subject":"Computational Fluid Dynamics","subitem_subject_scheme":"Other"},{"subitem_subject":"Protuberance","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":"Roll Moment Characteristics of Supersonic Flight Vehicle Equipped with Asymmetric Protuberance","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Roll Moment Characteristics of Supersonic Flight Vehicle Equipped with Asymmetric Protuberance"}]},"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":"9977","relation_version_is_last":true,"title":["Roll Moment Characteristics of Supersonic Flight Vehicle Equipped with Asymmetric Protuberance"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T19:00:30.590732+00:00"}
