It is shown that the low order trend (long wavelength component) included in a runway profile can seriously impair the estimated spectra, and therefore, a simple method to remove this trend is obtained. Next, power spectra of sixteen commercial runways are estimated, including the spectra of symmetric and anti-symmetric components between two tracks, to provide airplane design data on ground loads. Comparing the runway spectra obtained before and after overlay repair of runway surface, it is shown that the power spectral presentation is an effective method to evaluate runway roughness.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1037000","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-1037","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機体部"},{"subitem_text_value":"航空宇宙技術研究所機体部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Airframe Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山根, 皓三郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"外崎, 得雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMANE, Kosaburo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SOTOZAKI, Tokuo","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":"naltr01037.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr01037.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45296/files/naltr01037.pdf"},"version_id":"c79b8b8e-19ff-4b31-9a4c-0e46e6451182"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Estimation of Power Spectral Density of Runway Roughness","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of Power Spectral Density of Runway Roughness","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45296","relation_version_is_last":true,"title":["Estimation of Power Spectral Density of Runway Roughness"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:41:51.228274+00:00"}
