The tests were carried out over 6, 12, and 24 module clustered aerospike nozzles with full and 20 percent lengths of spike. Pressure distributions on surface of the nozzle were measured. Surface flow fields were visualized with a Shear Sensitive Liquid Crystal (SSLC). Wedge like surface flow structures were observed at sea level condition. These structures were considered to be constructed by interactions between the nozzle surface and the shock waves of diamond cones of exhaust. Triangle like surface flow structures were observed at low and high altitude conditions. These structures were considered to be caused by interactions among neighboring exhausted jets. Observed structures above were constructed with shock waves, which was confirmed by the pressure distributions on the surface of the nozzle. White circle was observed on base in case of truncated nozzle at high altitude condition. The circle was considered to be caused by recirculation of wake of the base. Essential flow fields of 6, 12, and 24 module clustered aerospike nozzles were the same. Only the difference, namely, dimensions of the flow structures, was come from the difference of size of gaps between the modules. Flow fields which were estimated above by the surface flow fields will be confirmed with CFD which is undergoing. The results of CFD will be certified with measured pressure distributions and visualized surface flow fields obtained in these tests.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0001958009","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: NAL SP-41","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所"},{"subitem_text_value":"航空宇宙技術研究所"},{"subitem_text_value":"航空宇宙技術研究所"},{"subitem_text_value":"航空宇宙技術研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory"}]},"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":"冨田, 健夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高橋, 守"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小野寺, 卓郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田村, 洋"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tomita, Takeo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi, Mamoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Onodera, Takuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tamura, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"エアロスパイクノズル","subitem_subject_scheme":"Other"},{"subitem_subject":"表面流れ特性","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_scheme":"Other"},{"subitem_subject":"環状クラスタ型エアロスパイクノズル","subitem_subject_scheme":"Other"},{"subitem_subject":"コールドフロー実験","subitem_subject_scheme":"Other"},{"subitem_subject":"剪断応力感応液晶","subitem_subject_scheme":"Other"},{"subitem_subject":"流れの構造","subitem_subject_scheme":"Other"},{"subitem_subject":"計算流体力学","subitem_subject_scheme":"Other"},{"subitem_subject":"aerospike nozzle","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"surface flow characteristic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"annular clustered aerospike nozzle","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cold flow test","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shear sensitive liquid crystal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flow structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computational fluid dynamics","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"エアロスパイクノズルの表面流れ特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"エアロスパイクノズルの表面流れ特性"}]},"item_type_id":"5","owner":"1","path":["1891","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"37323","relation_version_is_last":true,"title":["エアロスパイクノズルの表面流れ特性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:21:53.353739+00:00"}
