Hot firing tests were conducted on a high altitude test stand, using four kinds of nozzles: a standard bell nozzle, a fixed step nozzle simulating the transient nozzle position during nozzle extension, a dual-bell nozzle, and a movable extendible nozzle. Measured nozzle performance, pressure distribution and heat transfer characteristics were compared with those of CFD analysis. The dual-bell nozzle performance was shown to be lower than that of the standard bell nozzle or the step nozzle. Reverse flow of combustion gas through the gap between the fixed nozzle and movable extendible nozzle was not observed during nozzle extension.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047384000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-1464","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-4588","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00311347","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所 ロケット推進研究センター"},{"subitem_text_value":"航空宇宙技術研究所 ロケット推進研究センター"},{"subitem_text_value":"航空宇宙技術研究所 ロケット推進研究センター"},{"subitem_text_value":"航空宇宙技術研究所 ロケット推進研究センター"},{"subitem_text_value":"航空宇宙技術研究所 ロケット推進研究センター"},{"subitem_text_value":"航空宇宙技術研究所 ロケット推進研究センター"},{"subitem_text_value":"コスモテック"},{"subitem_text_value":"宇宙開発事業団"},{"subitem_text_value":"宇宙開発事業団"},{"subitem_text_value":"宇宙開発事業団"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Rocket Propulsion Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Rocket Propulsion Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Rocket Propulsion Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Rocket Propulsion Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Rocket Propulsion Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Rocket Propulsion Center"},{"subitem_text_language":"en","subitem_text_value":"Cosmotec Co.
