In the first report we studied the effects of extending the rectangular cut-out along the span or in the direction of the chord on the wing characteristics with respect to the case in which the cut end is not made fair. And it is of course that if the cut end is made fair the wing characteristics are also affected. In the present report the problem that what form is suitable as the cutaway section is studied. To this purpose the characteristics of the wing whose trailing edge is fully cut away along the span with four kinds of cut end were tested in the 1.5m wind tunnel at 30m/s wind velocity with regard to the two different profiles: the Gottingen 593 and 459 wings. It is concluded that the most suitable form of the four kinds is that which the cut end is made round with the inscribed circle, and it is still better to make the cutaway section similar to the original wing section if it is permitted from construction. And the flow pattern around the wing section whose trailing edge was cut away was obtained photographically in the 30m×1.5m×1.5m water tank of the institute.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4146447000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝國大學航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Aeronautical Research Institute, Tokyo Imperial University"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00387631","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡本, 哲史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKAMOTO, Tetusi","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":"SA4146447.pdf","filesize":[{"value":"3.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4146447.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35287/files/SA4146447.pdf"},"version_id":"43899daf-a958-47c7-80a2-17167ed3d8ba"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"On the Effects of Cutting Away the Trailing Edge on the Aerodynamic Characte-ristics of a Wing.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the Effects of Cutting Away the Trailing Edge on the Aerodynamic Characte-ristics of a Wing.","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1993"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35287","relation_version_is_last":true,"title":["On the Effects of Cutting Away the Trailing Edge on the Aerodynamic Characte-ristics of a Wing."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:22:39.684667+00:00"}
