The system consists of a reversed frustum of a cone as the main body, a heat protection umbrella attached to the front face of the body and a drag augmentation plate mounted on the base. The experiment is conducted in a blowdown type supersonic wind tunnel of Mach number 2, and the effects of geometrical factors associated wtih the additional facilities are examined in detail on the aerodynamic characteristics of the system. It is shown that the drag plate consisting of multiple separated element-plates has better area effectiveness for drag augmentation than that of a single disk, and the increase in diameter of each element-plate is more effective than the increase in width if the total area of the element-plates is kept constant. In view of these results, it is suggested that the drag reduction due to spike effect of the heat protection umbrella can be compensated by the drag plate having relatively small area, if the plate geometry is selected adequately. From the viewpoint of static stability, the attitude of the present system is longitudinally stable within a range of small angles of attack (|a|","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0125883000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空所究所"},{"subitem_text_value":"東京大学宇宙航空所究所"},{"subitem_text_value":"航空宇宙技術研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Labortory"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"辛島, 桂一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 清"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"楯, 篤志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KARASHIMA, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SATO, Kiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TATE, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0125883.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0125883.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32572/files/SA0125883.pdf"},"version_id":"b8383d62-c28c-427e-ac41-77e88a04ff72"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"<論文>再突入物体システムの超音速空力制動特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<論文>再突入物体システムの超音速空力制動特性"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32572","relation_version_is_last":true,"title":["<論文>再突入物体システムの超音速空力制動特性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:29:01.500783+00:00"}
