Simulation data of combustion pressure and mass flow rate of oxidizer are provided for different three cases to calculate two types of c* efficiency. The calculated results show that 1) ηrec and ηtrad are almost equal when the theoretical characteristic exhaust velocity, c*th, varies almost linearly against the variation of O/F ratio during the firing, 2) ηrec is greater than ηtrad when c*th varies non-linearly against the variation of O/F ratio, 3) ηrec is appropriate as a c* efficiency of a hybrid rocket.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"538","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"片野田, 洋","creatorNameLang":"ja"},{"creatorName":"KATANODA, Hiroshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"永田, 晴紀","creatorNameLang":"ja"},{"creatorName":"NAGATA, Harunori","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-23"}],"displaytype":"detail","filename":"No58-01.pdf","filesize":[{"value":"568.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"No58-01","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/13737/files/No58-01.pdf"},"version_id":"cb36ff40-f917-4b17-84b4-edb723337edc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hybrid Rocket","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"c* efficiency","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"ハイブリッドロケットのc*効率について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ハイブリッドロケットのc*効率について","subitem_title_language":"ja"},{"subitem_title":"c* Efficiency of Hybrid Rockets","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["36","5733"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-06-23"},"publish_date":"2017-06-23","publish_status":"0","recid":"13737","relation_version_is_last":true,"title":["ハイブリッドロケットのc*効率について"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T05:03:04.590720+00:00"}
