The base CFD code herein assumed is a three-dimensional compressible solver, <rFlow3D>, which has intensively been developed for helicopter applications at JAXA. The rFlow3D is a highly versatile CFD code that can numerically simulate flows around helicopter in a wide range of flow conditions, considering trimming and blade elastic deformation. In this study, the hybrid method is improved by introducing multi-trailers. Computational precision of the hybrid method is verified by comparing the computational results with the experimental data of HART-II (Higher harmonic control Aeroacoustics Rotor Test). Airload coefficient and BVI noise distribution approach to the experiment. And it is also found that computational time reduces about half to one-third of CFD/CSD (computational structural dynamics) coupling if CFD is conducted after the hybrid method is utilized since the hybrid method reflects periodic induced velocity of the prescribed wake model and a faster convergence in elastic deformation can be obtained.","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: AA0062268012","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-13-011","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":"宇宙航空研究開発機構航空本部機体システム研究グループ(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空本部機体システム研究グループ(JAXA)"},{"subitem_text_value":"株式会社菱友システムズ"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aircraft Systems Research Group, , Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Systems Research Group, , Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Ryoyu Systems, Co., Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"杉浦, 正彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田辺, 安忠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"菅原, 瑛明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugiura, Masahiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanabe, Yasutada","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugawara, Hideaki","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":"62268012.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62268012.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4012/files/62268012.pdf"},"version_id":"3faf7f95-1ead-429d-ad21-4f9cc73c288b"}]},"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":"ヘリコプタのBVI 騒音予測に向けたCFD と規定後流モデルのハイブリッド手法の改良","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヘリコプタのBVI 騒音予測に向けたCFD と規定後流モデルのハイブリッド手法の改良"}]},"item_type_id":"5","owner":"1","path":["877","1536","1880","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4012","relation_version_is_last":true,"title":["ヘリコプタのBVI 騒音予測に向けたCFD と規定後流モデルのハイブリッド手法の改良"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:49:59.127505+00:00"}
