The majestic whales have inspired a revolutionary innovation in ship propulsion tehcnology. A ship propulsion concept inspired by motion of a whale’s tail has emerged after a decade of research, development, and testing. ABB, a technology group, has unveiled a groundbreaking ship propulsion system that aims to reduce engine power use by 22% compared to traditional shaft line and propeller systems. The propulsion system, called Dynafin, features a main electric motor that powers a large wheel rotating at a moderate speed of 30-80 rounds per minute. Vertical blades, controlled individually by motors and control systems, extend from the wheel, generating … Continue reading A Whale-Tail Inspired Ship Propulsion Breakthrough: ABB’s Dynafin System Paves the Way for Greener Seas
