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 basic configuration of traditional propellers has not fundamentally changed since the first powered flight by the Wright brothers in 1903. However, as engineers learn more about aerodynamics and ...

It’s a rare occasion when a piece of engineering transcends its pure industrial function and becomes art. And it’s even rarer when that metamorphosis is the byproduct of a quest for better performance ...

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 ...

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 ...

These strangely-shaped twisted-loop propellers look like a revolutionary (sorry) advance for the aviation and marine sectors. Radically quieter than traditional propellers in both air and water, ...
