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 ...

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 ...

Airborne drones are already widely used for filming and are expected to help deliver packages without being affected by traffic jams, but the noise emitted by drones can be an obstacle to widespread ...

空を飛ぶドローンはすでに映像撮影に広く利用されているほか、交通渋滞などに左右されない荷物の配送にも役立つと期待されていますが、ドローンが発する騒音は広範な展開における障害となり得ます。新たに、マサチューセッツ工科大学(MIT)とアメリカ ...

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 ...

Discover how a redesigned toroidal propeller could revolutionize efficiency across various applications. By altering the shape of the propeller, significant improvements in energy efficiency ranging ...
