Being one of the new types of moderate skewed propeller with small area - ratio, the hudong type propeller is with virtues of high efficiency, low vibration and light in weight
Hudong型槳是滬東廠近年來借鑒國內外先進的螺旋槳設計技術,結合工廠設計與建造的實際船舶產品開發的中等側斜度、小盤面比螺旋槳。Hd propellers are a type of marine propellers having new blade sections, moderate skew and a small area - ratio, with the virtues of higher efficiency, lower vibration and noise and lighter weight
滬東型( hd )螺旋槳是一種新型的葉剖面、中等側斜、小盤面比的螺旋槳。它具有效率高、振動和噪音低、重量輕等優良性能。In the 1960 ' s, the circumfluence theory has been used to design the shroud - propeller, and it can be divided to two methods, one is that the profile of die shroud is provided, the other is that the pressure distribution of the shroud is provided.
到六十年代,函道螺旋槳的環流理論就可用來計算這種推進器的設計問題。本文中使用的方法是:函道用圓環渦系和圓環源、匯系模擬,用線性理論計算;螺旋槳用一個變負載的鼓動盤模擬。The running condition would be deteriorated and at last the parts of the engine would be damaged if the revolution were reduced too low. the propeller must be redesigned or be modified in this situation. people usually modify the propeller rather than change the propeller because it will be more easily and economical
此時若要更換新的螺旋槳必然造成經濟上過重的負擔,較方便可行的方法是對原來的螺旋槳採取切邊修改的方法,減少螺旋槳的直徑、盤面積或螺距,使螺旋槳的扭矩減小,螺槳變「輕」 。分享友人
