When the power required by propeller is so high that the shaft speed cann't arrive a rated value, the tip of propeller can be cut to decrease its load.
当螺旋桨要求的功率过高以至于轴转速达不到额定值时，可以采用切割螺旋桨叶梢的方法减小螺旋桨的负荷。
This paper concisely describes the selection of propeller type and interaction coefficients for high speed, and gives the application of some diagrams and empirical formulas.
本文扼要地介绍了高速船螺旋桨设计中碰到的螺旋桨选型问题、相互作用系数选取问题以及某些图谱和经验公式的应用。
The interaction noise induced by propeller has constituted the main part of the noise radiated from the medium-speed or high-speed marines.
