国内散货船螺旋桨选型及经济性分析

Propeller Selection and Economic Analysis for Domestic Bulk Carrier

考虑到国内新造散货船普遍采用大直径螺旋桨匹配更低转速柴油机后,设计指标提升明显,结合国内散货船实际营运航线情况,对国内散货船航线特点,船型特点进行总结,分析不同螺旋桨选型的船舶全航程下经济性。

A new design concept of larger propeller matched with lower-speed diesel engine is adopted in the new developed and built domestic bulk carrier,in order to promote the designed index of the ship.Based on the actual operating voyage of domestic bulk carriers,the characteristics of route and ship type for domestic bulk carriers were summarized,and the economy of ships with different selection of propeller during the ship’s full voyage range was analyzed.
