Though, the major efforts have been made in order to develop a revolutionary high quality balloon film, the author is confident that there are great possibility to increase pressure durability by improving not only the film strength but also the balloon shape design. For this purpose, at first, the theory of Smalley's natural shape balloon with road tapes, which is adopted as a standard design of modern scientific balloons, is reviewed from this view point. The study shows that the current balloon shape is not always designed suitable for a pressurized balloon. Then a new design and fabrication concept, named three dimensional (3-D) gore design method, is proposed. This new method can easily realize stronger balloon than the conventional ones. In addition, the pressure durability does not depend on the balloon volume. These superior characteristics are quite different from those we are using now. To verify the effect of the new design concept, a pressurized test was accomplished by means of a small pumpkin shape balloon designed by a 3-D gore method. The burst pressure of the small model balloon was almost three times larger than the same size balloon designed by the conventional manner. The experimental results are also presexted in detail.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0167140000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","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":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"矢島, 信之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAJIMA, Nobuyuki","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":"SA0167140.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0167140.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33211/files/SA0167140.pdf"},"version_id":"ffb59f1c-4428-4e10-8bab-13096f40801e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"科学気球","subitem_subject_scheme":"Other"},{"subitem_subject":"自然型気球","subitem_subject_scheme":"Other"},{"subitem_subject":"スーパープレッシャー気球","subitem_subject_scheme":"Other"},{"subitem_subject":"膜構造","subitem_subject_scheme":"Other"}]},"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":"自然型気球の基本特性 : 高耐圧気球実現のための再検討と新しい設計・製作法の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自然型気球の基本特性 : 高耐圧気球実現のための再検討と新しい設計・製作法の試み"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33211","relation_version_is_last":true,"title":["自然型気球の基本特性 : 高耐圧気球実現のための再検討と新しい設計・製作法の試み"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:12:41.587242+00:00"}
