混合对转推进系统设计与实船应用研究

为全面深入了解混合对转推进系统实船安装对船舶性能影响,为数值仿真和性能预报提供实船参考数据,以集装箱运输船为应用对象,提出了一种把吊舱推进器集成在挂舵臂上的混合对转推进系统(CRP-POD),详细阐述了CRP-POD的系统构成、工作模式和电气控制系统实船设计方案。通过实船试验和运行数据分析,安装混合对转推进系统的船舶与同系列安装常规推进系统的船舶相比,特定航行工况下航速有2~3%的提升、回转能力有所降低、航向稳定性上优于常规船。

Design of Hybrid CRP Propulsion System andResearch on Real Ship Application

A hybrid counter-rotation propulsion system that the podded thruster is integrated on the rudder horn is proposed and installed on a container transport ship. The purpose of the paper is to fully explain the impact of hybrid CRP propulsion system on ship performance during its operation in reality, to provide real ship operation reference data for numerical simulation and performance research for CRP system. The system composition, working modes and the design of the electrical control system for the CRP-POD system are described in detail. Through actual ship tests and operational data analysis, compared with ships of the same series with conventional propulsion systems, ships with hybrid CRP propulsion systems have a 2~3% increase in speed under certain sailing conditions, reduced turning capabilities, and the course stabilities are superior to conventional ships.
