摘要
对于配置可调螺距螺旋桨的船舶,螺旋桨的推进特性同常规定螺距螺旋桨船舶有较大差异,ISO15016标准中对于配置可调螺距螺旋桨的船舶EEDI测速仅有少量描述,缺乏测速流程及修正方法。文中从螺旋桨推进本质角度分析可调螺旋桨的推进特性,介绍了常规推进船舶EEDI的校核流程,通过对配置可调螺旋桨的船舶可能出现的几种试航EEDI测速情况进行分析,提出较为可行的EEDI测速分析方法,以期为相关船型设计、试验及标准完善提供一定的依据。
The propulsion characteristics for ships equipped with controllable pitch propeller(CPP)is significantly different with fix pitch propeller(FPP).The ISO 15016 standard only provides less description for EEDI speed trial of ships with CPP.The characteristics for the CPPs were analyzed from the essence of propeller propulsion.The EEDI check procedure for conventional propulsion of FPP in ship design was introduced.A feasible EEDI speed analysis method was proposed by analyzing several possible EEDI test situations of ships equipped with adjustable propeller,so as to provide some reference for ship design,testing and the perfection of relevant criteria.
