Abstract
This paper briefly describes the composition and advantages of podded propulsion system and introduces the characteristics of ice-class podded propulsion system compared with ordinary podded propulsion system,including high strength and impact resistance,high torque overload multiples,and high-strength stainless steel propellers.It also analyzes the current status of ice-class podded propulsion system units from mainstream manufacturers at home and abroad,such as ABB,Kongsberg,GE,Wuchang Shipbuilding Industry Co.,Ltd.,and Wuhan Institute of Marine Electric Propulsion.It points out the key technologies and development directions of podded propulsion system in the ice region,including high-torque and overload-resistant electromagnetic optimisation design,efficient integrated motor cooling design,repairable bearing seal design inside the pod,and research on the coupling effects of multiple underwater structural components.Looking back the development history of podded propulsion systems,we urgently need to develop ice-class podded propulsion system with independent intellectual property rights to enhance our national competitiveness in the global shipbuilding field.
