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 shorter a drone's propellers, the less efficient they are at keeping it airborne. That factor, along with compact, low-capacity batteries, is the reason that small drones can't fly for very long.

Drones fly while rotating multiple propellers at high speed, which makes a loud buzzing noise during flight. Some drones have reduced noise by devising the shape of the propellers. In the 'Slow-motion ...
