摘要
本文介绍了例推孔低阻孔口的设计，阐述了侧推器的水动力外部特性、射流与船体的相互作用；分析了零航速时侧推器推力、功率与船体回转角速度的关系；对航速使侧推力下降的现象作了分析并推荐两种方法改善上述现象。
The paper provides a discussion on the design of low drag thruster tunnel ends,exterior hydrodynamic performance of the thruster,interaction of jet flow and hull,and on this base presents relationships among thrust,power rating and hull turning ample at ship's zero speed.After analysing the phenomena of thrust reduction at ship speed, the author proposes two methods for countering such phenomena.The purpose of the paper is to develop and propose an exterior design method for the thruster.
