摘要
泵喷推进器是一种结构复杂的多部件组合水下推进器,主要由导管、定子和转子三部分组成,具有高临界航速、高效率和低噪声等特点.国外泵喷推进器研究和应用较早,用于鱼雷和潜艇主推进器,国内研究工作相较起步较晚.介绍了潜艇及泵喷推进器周围流场特性,按照潜艇及推进器试验和数值模拟两方面总结了目前国内外泵喷流场特性研究现状;进一步针对泵喷推进器空化流动特性进行了分析,并介绍了目前推进器的结构优化策略;最后分析并总结了泵喷流场特性的研究以及实际应用中所面临的主要挑战.
Abstract
Pump-jet is a complex structure of multi-component combination of underwater propulsion,mainly consists of three parts:conduit,stator and rotor,with high critical speed,high efficiency and low noise and other characteristics.Foreign pump jet propulsion research and application of earlier,for torpedoes and submarines main propulsion,domestic research work compared to the late start.This paper introduces the characteristics of the flow field around the submarine and the pump-jet propeller,and summarises the current status of the research on the characteristics of the pump-jet flow field at home and abroad in accordance with the submarine and the propeller test and numerical simulation.The cavitation flow characteristics of the pump-jet thruster are further analysed and the current structural optimisation strategy of the thruster is presented.Finally,the study of pump-jet flow field characteristics and the main challenges faced in practical applications are analysed and summarised.
