Engine peak thrust and impulse were found to be increasing functions of temperature,with sensitivity coefficients of 0.022 N/K and 0.0054 Ns/K, respectively. The increase in the peak thrust isexplainable by the characteristics of pyrotechnics; however, the increase in the impulse is abnormal. This abnormalitycan be attributed to the increased exhaust gas flow from the delay charge due to the enhanced burning rateof the propellant. The effect of aging was also studied by conducting experiments using 1-, 5-, and 15-year-old A8-3model rocket engines. Impulse variation was small; however, there were large variations in the peak thrusts of theolder engines. These variations can be ascribed to cracks on the propellant surface caused by heat cycles duringlong-term propellant storage.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA12210629","subitem_source_identifier_type":"NCID"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-03-01"}],"displaytype":"detail","filename":"KJ00008928239.pdf","filesize":[{"value":"302.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"KJ00008928239","url":"https://metro-cit.repo.nii.ac.jp/record/153/files/KJ00008928239.pdf"},"version_id":"246acf69-09db-44df-8da1-22101f856ab0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Model rocket engine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Thrust measurement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Temperature and aging effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"15-year-old A8-3 model rocket engine","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A8-3 モデルロケットエンジンの温度特性と経年劣化の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A8-3 モデルロケットエンジンの温度特性と経年劣化の影響"},{"subitem_title":"Effects of Temperature and Aging on Performance of A8-3 Model Rocket Engines","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-03-01"},"publish_date":"2013-03-01","publish_status":"0","recid":"153","relation_version_is_last":true,"title":["A8-3 モデルロケットエンジンの温度特性と経年劣化の影響"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-04-29T06:13:38.665634+00:00"}
