Examples
- Virtual pitch ratio
实效螺距比 - 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
本文主要是考虑螺旋桨出现负荷过重时如何处理的问题，所以采用桨叶随边切割并在叶面处将翼型修顺的方式，实质上是切割后导致螺旋桨实效螺距的减小，从而使螺旋桨吸收的转矩降低来达到主机负荷降低的目的。
