摘　　要：以一艘220 000 m3 LNG船为例,介绍了大型LNG船螺旋桨的设计思想、设计过程和设计桨参数.不同于常规单桨船螺旋桨设计,双桨船的适伴流设计必须考虑切向伴流影响,给出了实效切向伴流分布的计算方法.模型试验结果表明设计桨的空泡和脉动压力性能优良,所有8个测点的脉动压力幅值都小于4kPa,推进性能满足航速要求.The design concepts, design procedures and propellers parameters are introduced, based on the propellers design of a 220 000m^3 LNG Carrier. Different from single propeller ships, the tangential flow must be considered when designing propellers for ships with double propellers, and the method of tangential flow distribution calculation is introduced. The model test results indicated that the performance of cavitation and fluctuating pressure of the tested propellers are good, the amplitudes of fluctuating pressure at eight test points are all below 4kPa, and the propulsion performance can meet the demands of ship speed.
