We made a series of experiments to find the optimum combination with the training ship Kakuyo-Maru (1,044.38G/T, 2,800HP) under various cruising speeds of 9～13.5 knots on October 22nd 1983 in the northwestern Pacific. Following results were obtained. i) Cruising speed, V (knot) and consumption of fuel oil, Gm (kg/n.m. running) were expressed by the following experimental formulae, where n is rpm of the main engine; S, slip ratio of propeller; θp, angular pitch of propeller blades. V=0.0241 n-0.15863 S+0.84685・θp-12.4791 Gm=0.04906・n-0.0086・V²+0.52406 S-0.06734・θp-11.91674 ii) The oil consumption was always smaller at the combination of lower rpm and greater pitch within the speed tested. However, when the angular pitch was 17° or greater, the temperature of exhaust gas often reached above its dangerous level. iii) The relative shaft-horse power at a constant rpm varied with pitch, i.e., the horse power at the pitches of 16° or 17° increased by 3.37 or 11.52% compared with the power at 15° of pitch.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.56, pp.33-42; 1984","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39371","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishiya, Toyonari"}]},{"nameIdentifiers":[{"nameIdentifier":"39372","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamaji, Mitsuyoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"39373","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Araki, Takeshi"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40002770822","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"西矢, 豊就"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山路, 光徽"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒木, 猛"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"suisan56_033.pdf","filesize":[{"value":"830.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan56_033.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9738/files/suisan56_033.pdf"},"version_id":"b8df4638-fb9a-496a-8f91-5df610a3bfc6"}]},"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":"舶用機関の省燃費運航に関する研究-1 : 基礎実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"舶用機関の省燃費運航に関する研究-1 : 基礎実験"}]},"item_type_id":"3","owner":"2","path":["725"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-28"},"publish_date":"2013-01-28","publish_status":"0","recid":"9738","relation_version_is_last":true,"title":["舶用機関の省燃費運航に関する研究-1 : 基礎実験"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:38:52.986353+00:00"}
