The airship was invented toward the end of the 19th century, and subsequently made rapid progress, falling into a rapid decline however with the remarkable advance of aircraft technology. Nowadays only small air-ships are utilized, for sightseeing and advertising. Airships are thought more suitable when the purpose is to remain stationary at high altitudes, because they gain lift by gas buoyancy, in contrast to aircraft, which gain lift by advance speed. In the concept of the stratospheric platform, many airships are floated in the stratosphere serving as platforms for communications, broadcasting or ground observation. As part of efforts to promote this concept, a Ground-to-Stratosphere Flight Test Vehicle and a Low-Altitude-Stationary Flight Test Vehicle are currently being developed. Many technical issues have emerged in the development of these vehicles. However a much severer design will be required to allow stationary flight at around an altitude of 20 km in the development of the stratospheric platform. Therefore research should be performed not only on the technical issues identified in the current test vehicle development, but also on issues in the stratospheric platform development. This memorandum discusses the design issues of an airship structure rather than the overall technical problems of the stratospheric platform. The topics covered are airship specifications, structure style, envelope materials, loads, stresses, sloshing, and test methods.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046102000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TM-772","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-460X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00314334","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所 成層圏プラットフォームプロジェクトセンタ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Stratospheric Platforms Project Center"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"前川, 昭二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Maekawa, Shoji","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":"2020-01-28"}],"displaytype":"detail","filename":"naltm0000772.pdf","filesize":[{"value":"295.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltm0000772.pdf","url":"https://jaxa.repo.nii.ac.jp/record/42858/files/naltm0000772.pdf"},"version_id":"b04b1d3a-f743-44bc-bf54-2ccb7b59df7e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"飛行船構造","subitem_subject_scheme":"Other"},{"subitem_subject":"成層圏プラットフォーム","subitem_subject_scheme":"Other"},{"subitem_subject":"高高度","subitem_subject_scheme":"Other"},{"subitem_subject":"静止飛行","subitem_subject_scheme":"Other"},{"subitem_subject":"通信","subitem_subject_scheme":"Other"},{"subitem_subject":"大気密度","subitem_subject_scheme":"Other"},{"subitem_subject":"飛行安全性","subitem_subject_scheme":"Other"},{"subitem_subject":"空力負荷","subitem_subject_scheme":"Other"},{"subitem_subject":"応力","subitem_subject_scheme":"Other"},{"subitem_subject":"スロッシング","subitem_subject_scheme":"Other"},{"subitem_subject":"破断強度","subitem_subject_scheme":"Other"},{"subitem_subject":"総覧","subitem_subject_scheme":"Other"},{"subitem_subject":"airship structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stratospheric platform","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"high altitude","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stationary flight","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"communication","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"atmospheric density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flight safety","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic load","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stress","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sloshing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tearing strength","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"general overview","subitem_subject_language":"en","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"成層圏プラットフォーム飛行船構造の設計課題","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"成層圏プラットフォーム飛行船構造の設計課題"}]},"item_type_id":"3","owner":"1","path":["1893","1916"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"42858","relation_version_is_last":true,"title":["成層圏プラットフォーム飛行船構造の設計課題"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:23:06.600744+00:00"}
