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_34": {"attribute_name": "メタデータ提供者", "attribute_value_mlt": [{"subitem_text_value": "メタデータ提供者: NAL-MATCH"}]}, "item_3_text_35": {"attribute_name": "JAXAカテゴリ", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ: 航空宇宙技術研究所"}]}, "item_3_text_36": {"attribute_name": "JAXAカテゴリ2", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ2: AP"}]}, "item_3_text_43": {"attribute_name": "DSpaceコレクション番号", "attribute_value_mlt": [{"subitem_text_value": "DSpaceコレクション番号: 9"}]}, "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": [{"nameIdentifier": "473607", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "稲垣, 敏治"}], "nameIdentifiers": [{"nameIdentifier": "473608", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SAKAI, NORIHO", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "473609", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "INAGAKI, Toshiharu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "473610", "nameIdentifierScheme": "WEKO"}]}]}, "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", "download_preview_message": "", "file_order": 0, "filename": "naltr00971.pdf", "filesize": [{"value": "2.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2100000.0, "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"], "permalink_uri": "https://jaxa.repo.nii.ac.jp/records/45230", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-03-26"}, "publish_date": "2015-03-26", "publish_status": "0", "recid": "45230", "relation": {}, "relation_version_is_last": true, "title": ["Characteristics of a Five-Hole Spherical Pitot Tube"], "weko_shared_id": -1}

内容記述 | A five-hole spherical pitot-tube produced for experimental purposes has been tested for measuring such air-data as velocity, angle of attack, sideslip angle and static-pressure of aircraft. 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. | |||||
