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 ...

Discover why this innovative toroidal propeller is attracting attention. By altering propeller design, we may have unlocked a way to enhance efficiency and reduce noise in drones and various propeller ...

When comparing the efficiency of different wind turbine blade designs, [AdamEnt] found using a hair dryer wasn’t the best tool for the job. Enter his new 3D-printed wind tunnel. After several ...

Despite being integral to aviation for more than a century, propellers have changed remarkably little since the Wright Brothers. A team at MIT’s Lincoln Lab has developed a new propeller shape that ...

The propellers of the world's ships and boats create a constant drone that disrupts ocean life. New propeller designs based on loops could one day quiet that drone and be more fuel efficient. Sharrow ...

February 23, 2023: Advances in technology often occur by accident, when you were looking for or developing something else. Such was the case with a new propeller design that sought to reduce the ...
