Multirotor drones are significantly more popular than conventional helicopter designs for many reasons, which do not include efficiency. Making use of the aerodynamic effects behind this, [Nicholas ...

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 ...

Vertical Take-Off and Landing (VTOL) drones typically have four horizontal propellers for moving up and down, along with a vertical rear "pusher" prop for moving forward in more efficient fixed-wing ...

A design that led to rapid development for the present concept is the Custer Channel Wing, a largely forgotten attempt to create ultra-short takeoff and landing (USTOL) airplanes nearly a century ago, ...

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 ...

A diagram shows how an Amazon drone could land on a sloping surface while keeping its main frame level, thanks to telescoping landing legs. (Amazon Illustration via USPTO) Amazon’s inventors are ...

Rutgers University just put out a video on a “drone” that can fly and then drop into a body of water, using its propellers to move around. This isn’t the first time we’ve covered a university making ...

We put FoxTech Supreme Carbon Propellers to the test on an RC aircraft. See how they perform in terms of thrust, stability, ...

Multicopter drones are neat and everything, but they do make a high-pitched whine – just image how annoying the sound of a large passenger-carrying version might be. It was with this in mind that ...
