In conventional monopropellant thruster of a spacecraft, hydrazine is used as propellant and catalytic ignition is employed. However, it is dangerous to handle hydrazine because hydrazine has high toxicity. Furthermore, in catalytic ignition, a catalyst tends to deteriorate by the high temperature and oxidation atmosphere. Recently, the study on green monopropellant is focused by other researchers for improvement of safety, performance and saving cost in operation of a thruster. Moreover, it is expected to apply a microchip-laser to spacecrafts in the future. In this study, we obtained combustion characteristics of green monopropellant in laser ignition and evaluated the feasibility of laser ignition for green monopropellant for spacecrafts.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1730012002","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: JAXA-RR-17-008","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/JAXA-RR-17-008/0002","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2216","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"長岡技術科学大学"},{"subitem_text_value":"長岡技術科学大学"},{"subitem_text_value":"長岡技術科学大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagaoka University of Technology"},{"subitem_text_language":"en","subitem_text_value":"Nagaoka University of Technology"},{"subitem_text_language":"en","subitem_text_value":"Nagaoka University of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古澤, 雅也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北村, 飛翔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"勝身, 俊之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Furusawa, Masaya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kitamura, Tsubasa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Katsumi, Toshiyuki","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":"2020-01-31"}],"displaytype":"detail","filename":"AA1730012002.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730012002.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1815/files/AA1730012002.pdf"},"version_id":"f78d0381-3bea-402e-82f4-4e692fd63352"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Green monopropellant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Laser ignition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Droplet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Focal length","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Propellant composition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressure measurement","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"スラスタ用低毒1液推進剤を対象にしたレーザー点火特性の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スラスタ用低毒1液推進剤を対象にしたレーザー点火特性の研究"}]},"item_type_id":"3","owner":"1","path":["31","1423","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-02-06"},"publish_date":"2018-02-06","publish_status":"0","recid":"1815","relation_version_is_last":true,"title":["スラスタ用低毒1液推進剤を対象にしたレーザー点火特性の研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:38:41.513078+00:00"}
