This multi-blade wind-turbine is featured by the presence of a stator before the rotor, which enables the turbine to give a higher power, a higher torque at a lower rotational speed than an ordinary wind air-turbine. A 3-kW AC-DC generator is driven by the air-turbine through a planetary speed-up gear of speed ratio 6. The rotational speed of this generator can automatically be kept at a desired value even in violent blizzards by means of an electric eddy-current brake newly developed by the authors. The brake also affords a new means for converting the wind energy directly into heat through the liquid heated in the jacket of the brake-stator. The present report describes the design of the whole system, the general perormance of the air-turbine, and the combined performance of the wind-turbine and generator evaluated in wind-tunnel tests and field tests at Syowa Station. The field tests have proved that a generator output of 2.4 kW can be obtained at a wind velocity of 30 m/s, and that the rotational speed of the generator can be kept at a desired value for variable loads and wind velocities exceeding 30 m/s.\"","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA0073354X","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"College of Science and Technology, Nihon University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1979-10-01"}],"displaytype":"detail","filename":"KJ00000011429.pdf","filesize":[{"value":"10.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011429","url":"https://nipr.repo.nii.ac.jp/record/23/files/KJ00000011429.pdf"},"version_id":"74c757b0-0c76-4fd5-a449-59e6d7e5355a"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Axial Flow Wind Air -Turbine NU-102 with Electric Eddy-Current Brake","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Axial Flow Wind Air -Turbine NU-102 with Electric Eddy-Current Brake","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["11"],"pubdate":{"attribute_name":"公開日","attribute_value":"1979-10-01"},"publish_date":"1979-10-01","publish_status":"0","recid":"23","relation_version_is_last":true,"title":["Axial Flow Wind Air -Turbine NU-102 with Electric Eddy-Current Brake"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:13:30.895557+00:00"}
