摘要
本文通过一艘LPC实船侧斜桨的设计论述了螺旋桨理论（包括水动力设计、结构有限元应力分布计算及脉动压力预报）如何支撑了整个设计过程。依赖此理论及软件，设计中螺旋桨的诸参数组合更为灵活，与传统的图谱设计方法相比、桨的综合性能明显提高。对22000M3LPG船侧斜桨的设计方案，经第三方水池模型试验，其性能超过了国外提供的方案。
In this paper, it is reported, how the propeller theories (including hydrodynamics design, stress distribution analysis by FEM and fluctuating pressure prediction)and computer code are supporting the propeller design for a LPC ship. As regarding to the traditional chat design methed, the propeller theory makes the design procedure more effective and flexible. Therefor, the propeller performances are much improved.
