Whipple が提案したアイデアを物理的に精査しメカニズムを明らかにすることによって、その防護システムの有効性を確認したものである。Fig.1(a)は同報告書に記載された、Ballistic, Shattering, Hypervelocity の3 つのRegimeの存在を示した図であり、Fig.1 (b)はこの3 つの領域の存在のために、1 枚板の貢通限界式に比べて2 重板シールドシステムの防護性能が如何に向上するかを示した図である。筆者らは、JAXA 宇宙機設計標準推進委員会デブリ防護設計WGの活動の一環として、「スペースデブリ防護設計マニュアル」の作成を行っているが、その過程で、衛星設計に資するため、実験によるのではなく、数値解析によって貫通限界式の検討を行った。その一例をFig.1(c)に示す。数値解析のみによって気化領域を含むWhipple シールドの貫通限界曲線(式)の推定を行ったのは世界的に見ても初めての試みであると思われる。","subitem_description_type":"Abstract"}]},"item_5_description_17":{"attribute_name":"抄録（英）","attribute_value_mlt":[{"subitem_description":"In 1991, K. B. Hayashida et al. at MSFC/NASA published a report reviewing the ballistic limit equations (BLE's)for the “Double-Plate”, so-called Whipple bumper shield, which was investigated as a protection technology for the space vehicle from interplanetary meteoroid impacts mainly for the purpose of the Apolloprogram in 1960's. The report also reviews the modified equations applicable for the space debris impact, after the space debris problem emerged in 1970's. The BLE's referred to in the report were derived on the basis of vast amounts of hypervelocity impact tests using launchers like two-stage light gas gun, it was confirmed and proven that the Whipple bumper shield is indeed effective for the meteoroid protection by investigating and clarifying the mechanism of it, of which idea was proposed by F. L. Whipple in 1947. Figure 1(a) depicts the existence of three regimes of the ballistic, shattering and hypervelocity, and Fig.1(b) indicatesthe effectiveness of the “Double-Plate” in comparison to the “Single-Plate”, both graphs are published in the report. The authors have been writing the “Design Manual on Space Debris Protection” as an activity of the Working Group of the Space Debris Protection Design at JAXA, and they tried to derive the ballistic limitcurves (equations) of small projectile impacts on the “Double-Sheet” targets only by the numerical analysis, not by the experiment. Figure 1(c) shows one of such curves. The derivation of the BLE's for the Whipple bumper shield only by the numerical method, taking into account the shock-induced vaporization, is probablyrecognized as the first trial in the world.","subitem_description_type":"Other"}]},"item_5_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_5_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_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0062322021","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-13-018","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"伊藤忠テクノソリューションズ株式会社(CTC)"},{"subitem_text_value":"伊藤忠テクノソリューションズ株式会社(CTC)"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所(JAXA)(ISAS)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ITOCHU Techno-Solutions Corporation (CTC)"},{"subitem_text_language":"en","subitem_text_value":"ITOCHU Techno-Solutions Corporation (CTC)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹場, 敦史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"片山, 雅英"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"仁田, 工美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeba, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Katayama, Masahide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nitta, Kumi","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":"2020-01-16"}],"displaytype":"detail","filename":"62322021.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62322021.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3921/files/62322021.pdf"},"version_id":"049ad81d-8ecf-4ed8-8023-bdd2d2036c83"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"衛星設計を目的とした微小デブリの2重壁への衝突過程の数値解析による貫通限界曲線の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"衛星設計を目的とした微小デブリの2重壁への衝突過程の数値解析による貫通限界曲線の推定"}]},"item_type_id":"5","owner":"1","path":["870","1505","1831","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"3921","relation_version_is_last":true,"title":["衛星設計を目的とした微小デブリの2重壁への衝突過程の数値解析による貫通限界曲線の推定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:52:02.666061+00:00"}
