Wind tunnel tests were subsequently performed in order to delay the onset of the wind buffet that prevented the performance of this flight test, and also to determine effective aerodynamic means to alleviate the buffet's strength. Results confirmed that both triangular fences fitted to the side of the nacelle and a dropped nose on the leading edge between the nacelles were most effective. These buffet countermeasures were then applied on ″ASKA″ and flight tests were conducted. It was found that the onset of a buffet was delayed and the vibration frequency of the airframe was reduced. This allowed the α-sweep testing to be safely carried out at higher angles of attack; hence enabling the initial objective to be achieved.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1129000","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 TR-1129","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":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"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新型航空機研究グループ"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"航空宇宙技術研究所空力性能部"},{"subitem_text_value":"川崎重工業株式会社"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Advanced Aircraft Research Group, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aircraft Aerodynamics Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kawasaki Heavy Industries, LTD."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 侔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中谷, 輝臣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 良生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"萱場, 重男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野口, 正芳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野中, 修"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"外立, 正隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"星野, 秀雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"馬場, 滋夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井上, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHASHI, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAYA, Teruomi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HAYASHI, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAYABA, Shigeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NOGUCHI, Masayoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NONAKA, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIDATE, Masataka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HOSHINO, Hideo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"BABA, Shigeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"INOUE, Takashi","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr01129.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01129.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45388/files/naltr01129.pdf"},"version_id":"e0da7656-4590-441b-99d3-66957f166aab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"STOL aircraft;
