In the Japan Aerospace Exploration Agency, the precooled turbojet (PCTJ) engine aimed at the hypersonic flight is under development. The takeoff noise of the full-scale vehicle is assessed before it is put into the operation using an acoustic simulation method. By matching the jet velocity and jet Mach number with the realistic PCTJ engine condition, the acoustic characteristics of the hypersonic nozzle are duplicated with a small-scale nozzle model. The jet noise database around the hypersonic nozzle is established through a number of experiments, and by taking into account 1) the nozzle scale, 2) the number of nozzles, 3) the direction of installation, 4) the measurement distance and angle based on the flight trajectory, and 5) the atmospheric absorption, the effective perceived noise level (EPNL) at the flyover point is calculated. It is shown that the nozzle configuration has a large impact on the takeoff noise, and that such an assessment could contribute to the improvement of the integration design of the vehicle.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: DS1540529005","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Society for Aeronautical and Space Sciences"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"日本航空宇宙学会"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-6460","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11307372","subitem_source_identifier_type":"NCID"}]},"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":"佐野, 典央"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 恭平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒木, 幹也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小島, 孝之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田口, 秀之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gonzalez, Palencia  Juan C."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"志賀, 聖一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sano, Norihisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Kyohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Araki, Mikiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kojima, Takayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taguchi, Hideyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gonzalez, Palencia  Juan C.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shiga, Seiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Takeoff Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nozzle Configuration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Effective Perceived Noise Level","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hypersonic Transport","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ノズル形態が極超音速航空機の離陸騒音に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ノズル形態が極超音速航空機の離陸騒音に及ぼす影響"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-28"},"publish_date":"2016-03-28","publish_status":"0","recid":"21689","relation_version_is_last":true,"title":["ノズル形態が極超音速航空機の離陸騒音に及ぼす影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:31:53.456742+00:00"}
