调距桨在800 kW拖船全回转导管桨上的应用研究
Research on the Application of Controllable-Pitch Propeller in 800 kW Tugboat’s Rudder Ducted Propeller

本文着眼于全回转港作拖船变工况使用的特点，系统分析了螺旋桨的工作特性，结合实船需要提出了将可调距螺旋桨与全回转导管桨结合设计的研究方向，并通过开展水动力分析、调距机构研发、机电一体化研究等工作，实现了可调桨在全回转导管桨上的应用，为同类船舶应用研究提供了借鉴。
Focusing on the characteristics of variable working conditions for controllable harbor tugboats, this paper systematically analyzes the working characteristics of propellers. Based on improving ship maneuverability, enhancing main engine power utilization, and improving fuel economy, this paper proposes a research direction combining controllable-pitch propellers with rudder ducted propellers in combination with actual ship needs. Through hydrodynamic calculation and analysis, research and development of pitch adjustment mechanisms, mechatronics research, and other work, the application of controllable-pitch propellers to rudder ducted propellers has been achieved, providing a reference for similar ship applications.
