为减少螺旋桨运转时所出现的空泡现象和水流的周期力对螺旋桨的作用,本文介绍了一种新型结构的调距桨,即这种螺旋桨在旋转一周过程中,在最大负荷区的叶片螺距减小,最小负荷区的螺距增大,也就是说,在螺旋桨旋转过程中,桨叶不停地往返小幅度摆动,从而使螺旋桨适于在不均匀的水流中运转。

In order to reduce the effect of cavitation phenomenon and periodic force of water flow on the propeller when the propeller is operating, a new type of pitch propeller is introduced in this paper. That is, during one revolution of the propeller, the pitch of the blade in the maximum load zone Decreases, the pitch of the zone of minimum load increases, that is to say that during the rotation of the propeller the blades constantly swing back and forth for a small amount, making the propeller suitable for operation in an inhomogeneous flow of water.
