負槳距 的英文怎麼說
中文拼音 [fùjiǎngjù]
負槳距
英文
negative piston-
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」 。The primary purpose of this paper is how to solve the overloaded propeller ' s condition. the style of propeller trailing edge cutting and shave on the pressure surface is adopted. the propeller ' s actual effect pitch will be reduced which cause the propeller ' s torque down
本文主要是考慮螺旋槳出現負荷過重時如何處理的問題，所以採用槳葉隨邊切割並在葉面處將翼型修順的方式，實質上是切割后導致螺旋槳實效螺距的減小，從而使螺旋槳吸收的轉矩降低來達到主機負荷降低的目的。
