一种系列化喷水推进装置的快速选型方法

A fast model selection method for marine series waterjets

船用喷水推进装置通常采用系列化的供货模式。喷水推进供货商依据提供的船舶主尺度、航速、动力系统等输入参数,通过船-机-泵匹配理论从系列化喷水推进产品中选择一型以满足需求。本文提出一种基于系列化喷水推进装置的快速选型方法,在仅已知设计航速和主机功率的条件下可快速选择适当的系列化喷水推进规格。本文方法适用于船舶的前期论证和方案设计阶段,船东或设计人员能利用本方法和喷水推进产品样本来实现快速选型。系列化快速选型的结果经分析误差较小,能够满足工程应用的需求。

Waterjets are usually supplied in a serialized model.The waterjet supplier selects one proper model from the series products according to the ship main dimension,design speed,power system and other input parameters provided and the ship-diesel-jet matching theory to meet the requirements.This paper presents a fast model selection method for marine series waterjets.Through this method,the appropriate marine series waterjet can be quickly selected under the condition that only the ship speed and main power are known.This method is suitable for the preliminary demonstration and scheme design stage of the ship.The ship-owner or designer can use the waterjet sample and this method to achieve fast model selection.The analysis error of the selection results is small,which can meet the needs of engineering application.
