In subsonic-transonic region, the particle phase properties are obtained by numerical integration of the characteristic equations along the particle stream lines, and the method of characteristics is then successfully applied to the supersonic region. The effects of the nozzle size, the throat geometry and the propellants on the thrust performance have been investigated in detail. The comparison between the calculation results and the experimental data shows that the specific impulse of practical motors can be well predicted by specifing the effective particle diameter of 1.8μ. The optimum nozzle shapes have been also investigated assuming parabolic contours, and a useful design chart for solid propellant motor nozzles is presented.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0034896000","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":"0285-6808","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":"AA10632072","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"DOI, Takao","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":"2020-01-23"}],"displaytype":"detail","filename":"SA0034896.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0034896.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31352/files/SA0034896.pdf"},"version_id":"0d56ac8a-10dd-4fa9-a0f4-e4dad5e6cf7d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gas-particle flows","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equilibrium flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"limiting particle stream line","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"specific impulse","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"optimum parabolic shape nozzle","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Gas-Particle Nozzle Flows and Optimum Nozzle Shape","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gas-Particle Nozzle Flows and Optimum Nozzle Shape","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1903"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31352","relation_version_is_last":true,"title":["Gas-Particle Nozzle Flows and Optimum Nozzle Shape"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T01:02:24.936073+00:00"}
