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.

Drone builders have challenges they face with each new design. If the drones are too big, they can't fit into tight spaces where they need to operate. If the drones are too small, they can't carry the ...

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 ...

If you’ve ever flown or watched anyone fly a racing drone for any length of time, you know that crashes are just part of the game and propellers are consumables. [Adam] knows this all to well, decided ...

Most drone engineers pick a lane. You build for speed, or you build for range. Luke and Mike Bell, the father-and-son team from South Africa already famous for pushing electric quadcopters to ...

The same qualities that make drones fantastic tools for capturing amazing aerial footage can also make them a genuine threat that’s difficult to intercept when misused. But a clever new design for an ...

EPFL startup Flybotix has developed a novel drone with just two propellers and an advanced stabilization system that allow it to fly for twice as long as conventional models. That fact, together with ...
