摘要
表面桨又称割划水面的桨,也称半潜桨。由于表面桨一般在斜向流中工作,且存在桨叶出入水面,所以表面桨在工作时会产生垂向力。从原理上对表面桨垂向力产生的原因做了初步分析,为对表面桨的进一步研究提供参考。
Surface propeller is known as surface-piercing propeller, or semi-submerged propeller. It usually works in the oblique flow, and its blades come into and out of the water surface, therefore vertical forces are generated as the propeller rotates. Analysis on the cause of vertical forces is made in this paper,in order to provide a reference for further research on the surface propeller.
