Progress in Hybrid Propulsion Drive System
, 2023 The paper provides an overview of current marine hybrid propulsion drive solutions, focusing on a particular device for engaging and disengaging the electric motor or diesel engine on the same propeller shaft line. The coupling system is controlled by an overrunning clutch (freewheel type) with ball bearings, allowing a fast change in diesel or ...
