摘要
螺旋桨的进流品质对螺旋桨效率与船舶推进性能有很大的影响。螺旋桨的进流补偿导管是以改善螺旋桨进流为主,从而改进船舶的推进性能,它本身亦产生附加推力,有节能效果,视船型和方形系数不同达5～11％。本文介绍江海直达1000吨沿海货船“闽海102”采用补偿导管的模型试验和实船试航结果。
This paper introduces a propeller inflow compesative simplified nozzle, which can improve the inflow on the propeller and reduce the flow separation on the ship stern, thus improving the propulsive efficiency. An example of the model test result and the sea trial result on a 1000 ton coaster is given in the paper.
