定距螺旋桨对船用主机外特性的要求分析

Analysis of requirements for the marine engine external characteristics of the fixed pitch propeller

为解决定距螺旋桨与船用主机在船舶运行工况的机桨匹配问题,结合船舶系泊和航行试验的相关标准,分析和归纳船舶运行数据,将实船测试与船机桨匹配理论计算相结合,得出运输船和拖轮在常用工况及特殊工况下定距螺旋桨对主机外特性的定量要求,为配套不同细分市场时船用主机的优化和开发提供参考依据。

In order to solve the matching problem between the propeller and the marine main engine in the operating condition of the ship,the paper combines the relevant ship mooring and navigation test standards,analyzes and summarizes the ship′s operational data,and combines the actual ship test with the theoretical calculation of the ship′s paddle matching.After research and analysis,the quantitative requirements for the outer characteristics of the fixed-propellers of the ship and the tugboat under common working conditions and special working conditions are obtained,which provides reference for the optimization and development of marine mainframes for different market segments.
