摘要: 螺旋桨是船舶的核心部件,破冰船螺旋桨性能的优劣直接关系到全船的快速性能、破冰性能、振动噪声性能和安全航行性能,故冰级螺旋桨设计是破冰船设计过程中的关键环节,需要确保螺旋桨性能满足设计指标要求。冰级螺旋桨运行于冰水环境,螺旋桨设计时需要考虑冰块对螺旋桨的影响,而国内在冰级螺旋桨设计方面缺少经验。该文在对冰级螺旋桨特点分析基础上,建立了冰级螺旋桨设计流程(IPDP),以一型PC2级重型破冰船螺旋桨设计为例,给出了设计结果和模型试验的验证结果。研究表明:冰级螺旋桨负荷重、工况多,其设计流程不同于常规螺旋桨,需要特别关注螺旋桨主参数与船型参数的迭代设计,既要验证敞水域航行的快速性能和振动性能,又要验证冰区航行的快速性能和螺旋桨强度性能等;对高冰级螺旋桨,需要设计成桨叶可拆式定距桨型式,方便单片桨叶的维修更换。

Abstract: Propeller is the core component of a ship. The performance of the propeller of an icebreaker is directly related to the speed/power performance, ice-breaking performance, vibration and noise performance and safe navigation performance of the whole ship. The design of the ice class propeller is therefore the key stage during the design of the icebreaker. It is necessary to ensure that the performance of the propeller can meet the design requirements. Different from the conventional propeller that operates in the open waters, the ice class propeller operates in the ice waters. The impact of the ice on the propeller should be considered during the design of the ice class propeller. However, there is little experience of the ice class propeller design in China. The ice class propeller design process (IPDP) has been established based on the analysis of the characteristics of the ice class propeller in the current study. The design results and model test results of the ice class propeller of a PC2 heavy icebreaker are presented. The results show that the design process of the ice class propeller is different from that of the conventional propeller with special focuses on the iterative design of the propeller parameters and hull parameters, due to the heavy load and multi-working conditions of the ice class propeller. It is necessary to verify not only the speed/power performance and vibration performance in the open waters, but also the speed/power performance and propeller strength performance in the ice regions. A detachable fixed pitch propeller is designed for the high ice class propeller to facilitate the repair and replacement of one single blade.
