The test model has three clustered cell nozzle modules or nonclustered two-dimensional nozzle with a designed Mach number of 3.5, and is connected to a straight section following a contoured spike. The model is given with a Mach 2.0 air stream as an external flow to simulate an off-design transonic flight condition. Measured pressure distributions on the spike surface indicated that the external flow makes the entire flowfield on the spike surface more uniform compared to those for the conditions without-external flow by eliminating periodic compression/expansion feature of cell nozzle jet. Results of flow visualization found that those tendencies are mainly governed by the fact that the external flow controls jet expansion by pressing it against the wall by forming a slip surface between cell nozzle flow and external flow. This fact made the spike base pressure higher than environmental pressure level when the external flow exists. Those effects of external flow showed advantages in thrust performance operated at off-design flight conditions.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AC1400046000","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: AIAA2014-0551","subitem_description_type":"Other"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"American Institute of Aeronautics and Astronautics(AIAA)"}]},"item_5_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.2514/6.2014-0551"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.2514/6.2014-0551","subitem_relation_type_select":"DOI"}}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"髙橋, 英美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"富岡, 定毅"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"冨田, 健夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"櫻中, 登"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi, Hidemi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomioka, Sadatake","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomita, Takeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakuranaka, Noboru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Flowfield Characterization of Linear Aerospike Nozzles","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Flowfield Characterization of Linear Aerospike Nozzles","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"38626","relation_version_is_last":true,"title":["Flowfield Characterization of Linear Aerospike Nozzles"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:38:14.569487+00:00"}
