内河40m长电力推进客船的机桨匹配设计

The Engine and Propeller Matching Design of 40 m Electric-propulsion Inland Passenger Ship

通过调查了解松花湖水域客船基本情况，选定船长为40 m的客船，采用电力推进方式。根据目标船的设计参数，对船舶的运行阻力进行了预估，进而求出船舶的有效功率。结合B4—70型螺旋桨图谱，对目标船舶进行了机桨匹配设计。

Through the investigation of the basic situation of passenger ship on Songhua lake, the 40 m electric propulsion passenger ship was selected as the target ship. According to designed parameters of target ship, the ship＇ s resistance was esti-mated, and the effective power was obtained. Then target ship＇ s main engine and propeller were matched in the line with propel- let＇s ]34-70 atlas.
