Among them, Japan's H-2A launch vehicle is given a low rank because of causing multiple orbital break-ups. Among the launch vehicles in the world, there are vehicles that generate many fragments due to explosions of residual propellants, etc., but the H-2A is ranked low even though it has never caused an explosion due to residual propellants. I believe that the cause of the H-2A's fragmentation is peeling of the insulators covering the cryogenic propellant tanks of the second stage. A similar phenomenon appears to have occurred at DELTA-4 in the United States. Here, the technical ground for this insight is shown from the orbital data of the peeled fragments. As part of the basic sales promotion strategy for the H-2A and next-generation H-3 launch services for the global market, we believe it is necessary to disclose the cause of this problem, make serious efforts to improve it, and disseminate it to the world.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_4_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA2230027032","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/00049205","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"加藤技術士事務所"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kato Professional Engineer’s Office"}]},"item_4_version_type_30":{"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":"加藤, 明"}],"nameIdentifiers":[{"nameIdentifier":"554829","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KATO, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"554830","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-02-28"}],"displaytype":"detail","filename":"AA2230027032.pdf","filesize":[{"value":"4.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA2230027032.pdf","url":"https://jaxa.repo.nii.ac.jp/record/49223/files/AA2230027032.pdf"},"version_id":"83705f32-a993-4b1f-826d-92389b162839"}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Orbital Fragmentation of Insulator from H-2A Launch Vehicles","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Orbital Fragmentation of Insulator from H-2A Launch Vehicles","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["1891","2263"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-02-28"},"publish_date":"2023-02-28","publish_status":"0","recid":"49223","relation_version_is_last":true,"title":["Orbital Fragmentation of Insulator from H-2A Launch Vehicles"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T18:39:31.205599+00:00"}
