Propeller Design 螺旋桨设计

To meet the high demand for modern ships on energy saving and emission reduction, on comfort and reliability, and on underwater radiated noise control, sophisticated propeller designs can only be achieved by using Computational Fluid Dynamics (CFD), combined with propeller design experiences, and validated by dedicated model tests. Contemporary propeller designs are all tailor-made for specific ships with specific operational mission profiles. A well balanced propeller design between efficiency, cavitation, pressure pulse levels, erosion and strength is essential. Based on the wide scope of R&D studies carried out on propulsion systems in the past and the vast experience of propulsion system applications, SSSRI-MARIN offers the high-end propeller hydrodynamic designs.

为满足现代船舶更高的需求,包括节能减排、舒适度和可靠性以及水下雷达噪声控制等方面,复杂的螺旋桨设计仅能依赖于计算流体动力学(CFD)、以往螺旋桨设计经验及专门的模型试验验证来实现。现代所有螺旋桨设计均是为满足特定航行任务的特定船舶定制的。一个好的螺旋桨能够良好平衡效率、空化、压力脉冲水平、腐蚀和强度方面是非常重要的。基于过去系统推进方面广泛的研究与开发以及大量的推进系统应用的经验,合资公司会提供高端螺旋桨水动力设计。
