Those concepts were initially developed for the main landing gear of the JAXA's experimental aircraft, ''Hisho,'' based on the Cessna Citation Sovereign, and were tailored to the two-wheel main landing gear after a careful investigation of flow fields around it with computational fluid dynamics simulations, far-field noise measurements with a 10%- scale wind tunnel model and an evaluation of the structural feasibility. The initial design was then improved upon by further investigations with a 20%-scale wind tunnel model and additional computational simulations. Six types of low noise devices were prepared: a porous cover around the tire axle and the lower half part of the strut, a plate between the mid door and strut, a porous plate on the side brace, wheel holes sealed with aluminum tape, a door arm with porous plates. Significant noise reduction, 5.5 dB(A) in overall sound pressure level at a position directly below the main landing gear and 4.5 EPNdB, was achieved.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"著者名の誤記: TKAISHI,Takehisa","subitem_description_type":"Other"},{"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":"The clerical error of an author's name: TKAISHI,Takehisa","subitem_description_type":"Other"},{"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: AA2130027010","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-21-008","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_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"住友精密工業株式会社"},{"subitem_text_value":"三菱重工業株式会社"},{"subitem_text_value":"川崎重工業株式会社"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Sumitomo Precision Products Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Mitsubishi Heavy Industries, Ltd."},{"subitem_text_language":"en","subitem_text_value":"Kawasaki Heavy Industries, Ltd."}]},"item_5_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":"伊藤, 靖"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高石, 武久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"少路, 宏和"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"島田, 彰久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 賢亮"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"上野, 陽亮"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAISHI, Takehisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHOJI, Hirokazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIMADA, Akihisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HAYASHI, Kensuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UENO, Yosuke","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":"2022-02-14"}],"displaytype":"detail","filename":"AA2130027010.pdf","filesize":[{"value":"13.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA2130027010.pdf","url":"https://jaxa.repo.nii.ac.jp/record/48383/files/AA2130027010.pdf"},"version_id":"0af3698d-d3dc-48a4-91c4-f164ab68af22"}]},"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":"リージョナルジェット機2輪主脚に対する低騒音化設計","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"リージョナルジェット機2輪主脚に対する低騒音化設計"}]},"item_type_id":"5","owner":"1","path":["1891","2188","2195","2196"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-02-14"},"publish_date":"2022-02-14","publish_status":"0","recid":"48383","relation_version_is_last":true,"title":["リージョナルジェット機2輪主脚に対する低騒音化設計"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T18:42:23.478030+00:00"}
