The present data are obtained with different propellant species (Ar, NH_3 and H_2) for discharge current ranging 3 and 25 kA. It was found that three arc modes (diffuse, spot and gross-erosion modes) exist and the electromagnetic scaling law is valid in MPD arcjet. In addition, current distribution, cathode erosion, voltage-current characteristics and thrust efficiency depend strongly on propellant species. The thrust performance for H_2 or NH_3 is better than that for Ar. Thrust efficiency was found to increase monotonically with specific impulse, reaching a value of 39% at 6500 sec for H_2 and 27% at 2500 sec for NH_3.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166618000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪大学基礎工学部"},{"subitem_text_value":"大阪大学基礎工学部"},{"subitem_text_value":"大阪大学基礎工学部"},{"subitem_text_value":"大阪大学基礎工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉川, 孝雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加賀谷, 洋一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"島本, 恭次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"横井, 洋一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIKAWA, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAGAYA, Yoichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIMAMOTO, Yasuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOKOI, Yoichi","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0166618.pdf","filesize":[{"value":"770.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166618.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32844/files/SA0166618.pdf"},"version_id":"2a1e7382-5e41-4425-a127-2da11e154de6"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"準定常 MPD アークジェットの推力特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"準定常 MPD アークジェットの推力特性"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32844","relation_version_is_last":true,"title":["準定常 MPD アークジェットの推力特性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:22:36.052202+00:00"}
