We obtained field data of total sulfur concentration in bio-ethanol produced in normal process in bio-ethanol plant and found that normal bio-ethanol will not cause the sulfur attack problem. However, we observed the increase of surface roughness because of coking when Inconel was used. Furthermore, we found that a temperature of approximately 500K have to be taken into account for designing a combustion chamber, because bio-ethanol starts to decompose and heat transfer coefficient starts to decrease at around 500K. From the engine system calculation taking into account the effect of coking, we found that the driving factor of the number of times of reusability is not the material cycle fatigue but coking and obtained estimated number of times of reusability. From this study, we obtained beneficial results for designing the regenerative cooled rocket engines by use of bio-ethanol.\nBasic properties of HAN/AN/methanol/water mixture solutions were examined for evaluating the safety of the propellant. The risk assessment proved the risk level of the propellant loading operation of HAN is lower than that of hydrazine and as same level as other green propellant candidates. From the large scale gap test (LSGT), we found that SHP163 has low sensitivity compared to other high energetic materials. From the measurement of thermal decomposition temperature, we found the contributing factors for decreasing the thermal decomposition temperature and suggested a rough standard of lower limit of decomposition temperature. From burning rate measurement, the effect of each component in HAN/AN/Methanol/Water mixture onto the burning rate became clear. From this study, we obtained beneficial results for evaluating the safety of this monopropellant.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_81_dissertation_number_13":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第394号"}]},"item_81_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15118/00009190","subitem_identifier_reg_type":"JaLC"}]},"item_81_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"501","subitem_subject_scheme":"NDC"}]},"item_81_text_12":{"attribute_name":"学位の種別","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"課程博士"}]},"item_81_text_14":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"甲第394号"}]},"item_81_text_15":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"博甲第394号"}]},"item_81_text_16":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"工学専攻"}]},"item_81_version_type_24":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"東,  伸幸","creatorNameLang":"ja"},{"creatorName":"AZUMA, Nobuyuki","creatorNameLang":"en"},{"creatorName":"アズマ, ノブユキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-06-24"}],"displaytype":"detail","filename":"A394.pdf","filesize":[{"value":"20.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A394","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/9224/files/A394.pdf"},"version_id":"029deafa-f1a1-4450-ab64-c3fd35946adc"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-19"}],"displaytype":"detail","filename":"A394_summary.pdf","filesize":[{"value":"176.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A394_summary","objectType":"abstract","url":"https://muroran-it.repo.nii.ac.jp/record/9224/files/A394_summary.pdf"},"version_id":"0c18bee9-0a0b-466a-8ff9-34ca6e255ccb"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"宇宙推進システムに用いるグリーンプロペラントの基本特性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"宇宙推進システムに用いるグリーンプロペラントの基本特性に関する研究","subitem_title_language":"ja"}]},"item_type_id":"81","owner":"18","path":["227"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-19"},"publish_date":"2017-05-19","publish_status":"0","recid":"9224","relation_version_is_last":true,"title":["宇宙推進システムに用いるグリーンプロペラントの基本特性に関する研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-10-29T23:47:48.217050+00:00"}
