Mathematicians call the shape of a doughnut a 'toroid'. Physicists call a swirling fluid a 'vortex'. A toroidal vortex, then, is a swirling doughnut of fluid. This video from the Sleek Geeks archive ...
These strangely-shaped twisted-toroid propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, ...
This paper by TSAW Drones discusses the need for less noise in UAVs, how these toroidals can benefit the drone industry, how these propellers came to be and how exactly they reduce the noise. Also, in ...

Why is this propeller getting so much attention?

Discover how a redesigned toroidal propeller could revolutionize efficiency across various applications. By altering the ...
A fried breakfast food popular in Spain provided the inspiration for the development of doughnut-shaped droplets that may provide scientists with a new approach for studying fundamental issues in ...
Surface wrinkling morphologies in various living matter with toroidal geometry. (a) Bidirectional stripes on a garlic. (b) Hexagonal-labyrinth bistable patterns on a dehydrated pepper. (c) Transverse ...
Scientists have confirmed that our solar system initially had the shape of a doughnut or a flat disk, a formation estimated to be around four and a half billion years old. In the Initial stages, our ...
