There are few cases in measuring the static-pressure by five-hole spherical pitot-tube, although the measurements of air-speed, angle of attack and sideslip-angle are well known. Since the five-hole spherical pitot-tube is normally installed at a position far from the lifting surface, one can expect to measure the static-pressure without position-error. At first, wind-tunnel tests of the five-hole spherical pitot-tube were conducted. The presure on the surface of the sphere was different from that estimated by theory. Such a difference between theory and practice induced considerable adverse effects on the accuracy of the measured air-data. So, by using new revised equations based on the results of the wind-tunnel tests, we were able to estimate all the air-data with much more accuracy. Next, we made some flight-tests in order to ascertain position-error in free static-pressure measurements. The tests were performed under such conditions as level-flight, steady-turn, landing and take-off during the experiments. The static-pressure measured by the five-hole spherical pitot-tube agreed well with measurements taken with a swivel-pitot and the resulting air-speed has been shown to be almost the same as that obtained from the position-error correction chart, which was made by the speed-course method.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0971000","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-971","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飛行実験部"},{"subitem_text_value":"航空宇宙技術研究所飛行実験部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Flight Research Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Flight Research Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"坂井, 紀穂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"稲垣, 敏治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAKAI, NORIHO","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"INAGAKI, Toshiharu","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":"naltr00971.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00971.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45230/files/naltr00971.pdf"},"version_id":"31ed11bb-ef13-49fb-85a6-121c9216485e"}]},"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":"Characteristics of a Five-Hole Spherical Pitot Tube","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characteristics of a Five-Hole Spherical Pitot Tube","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":"45230","relation_version_is_last":true,"title":["Characteristics of a Five-Hole Spherical Pitot Tube"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:42:59.538006+00:00"}
