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 ...

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, ...

As boring as propeller designs may seem to the average person, occasionally there’s a bit of a dust-up in the media about a ‘new’ design that promises at least a few percent improvement in performance ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Recently, a major breakthrough in the field of optical toroidal vortices has been achieved and published in ...

Toroidal pulses Air cannons produce visible vortex rings by generating rotating air pressure differences, while electromagnetic cannons emit electromagnetic vortex pulses using coaxial horn antennas. ...

Continuously variable transmissions are great for a lot of reasons, but they do have one drawback: They're not able to handle large amounts of torque. Nissan figured out a way past this problem for ...
