This report describes a preliminary effort to develop a C/C composite chamber, as well as to develop an injector for a low thrust storable engine. Performance tests of injectors for a 2000 N thrust class, fuel film cooled, NTO/MMH propellant engine were conducted at sea level with a workhorse combustion chamber. It was shown that a graphite nozzle insert could be used repeatedly for performance evaluation at a firing duration of 7 seconds. The energy release efficiencies of the core injectors used were estimated to be 97.5％ at the design mixture ratio of 1.65. The vacuum specific impulse predicted for an injector with 15％ film cooling with a 200:1 area ratio nozzle was 310s at a mixture ratio of 1.65 and a chamber pressure of 0.85 MPa. No combustion instability or popping were obserged up to a chamber presure of 1.6 MPa. A C/C composite chamber with SiC coating on the inner wall and organic silicide coating over the carbon CVD layer on the outer wall was selected for the firing test. Two sea level tests, of 30 s and 60 s durations, at a chamber pressure of 0.85 MPa were demonstrated on a single C/C composite chamber. It was shown that the basic C/C composite material had sufiicient high-temperature strength and that the SiC coating on the inner wall was durable at the operating conditions. The outside carbon CVD coating seemed to be effective in shutting off the permeability of the combustion gases from the inside of the chamber. However, the organic silicide coatings applied to protect the carbon CVD layer from oxidizing atmosphere in sea level tests were not sufficiently effective. The firing duration was limited to 60 s because of an inadequate seal between the C/C composite chamber and the metal injector.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0946000","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-946","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":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"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角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"航空宇宙技術研究所角田支所"},{"subitem_text_value":"日産自動車株式会社"},{"subitem_text_value":"日産自動車株式会社"},{"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":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Kakuda Branch Office, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Nissan Motor Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Nissan Motor Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"National Space Development Agency of Japan(NASDA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"日下, 和夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"植田, 修一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 登"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宮島, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"桑原, 卓雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小坂, 勝明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長島, 隆一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUSAKA, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UEDA, Shuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ABE, Noboru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAJIMA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUWAHARA, Takuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOSAKA, Katsuaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGASHIMA, Ryuichi","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00946.pdf","filesize":[{"value":"3.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00946.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45205/files/naltr00946.pdf"},"version_id":"9704431c-71f2-4f7c-abe5-079a0aad0ad2"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Fabrication and Test of a Carbon-Carbon Composite Combustion Chamber for a Low Thrust Storable Engine","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fabrication and Test of a Carbon-Carbon Composite Combustion Chamber for a Low Thrust Storable Engine","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45205","relation_version_is_last":true,"title":["Fabrication and Test of a Carbon-Carbon Composite Combustion Chamber for a Low Thrust Storable Engine"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:43:24.688957+00:00"}
