Earlier this month, we featured a Whale Design propeller that looked to nature for improved efficiency. Switzerland's ABB Marine has also been inspired by "the dynamic motions of a whale's tail" for its multi-blade Dynafin propulsion concept.Continue ReadingCategory: Marine, TransportTags: Shipping, Boating, Motor, Energy-efficient

toroidal propellers turn your drones and boats into noiseless machines
Posted by judy82 649 days ago (https://www.designboom.com)
how toroidal propellers could impact aerial + marine sectors First devised by Archimedes in 200 BC, propellers are mechanical devices composed of several blades that rotate at high speed to enable an aircraft or water vehicle to move across a distance. Humans have been optimizing these engines for centuries, but changes seem to have […]

Toroidal propellers: A noise-killing game changer in air and water
Posted by ArielTechGeek 649 days ago (https://newatlas.com)
Propellers are designed to take a fluid, generally air or water, and use a rotating motion to push that fluid through. They're evolutions, in a sense, from the Archimedes' screw, which was likely used in ancient Egypt thousands of years before it was described by Archimedes in 234 BCE.Continue ReadingCategory: Aircraft, TransportTags: drones, eVTOL, Electric Aircraft, Marine
