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 ...

As industries across the board strive for greater efficiency and cost savings, a new technology has emerged as a potential solution: the toroidal propeller. This innovative propeller design, inspired ...

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 the impact of a revolutionary propeller design that promises enhanced efficiency and reduced noise for drones and ...

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, ...

Sharrow's extraordinary looped propellers were already some 30% more efficient than traditional designs – and now the company has put two of them together into a coaxial, contra-rotating prop that ...
