After several prototypes, [AdamEnt] decided on a design that exploits slicer infill ... The BLDC motor driving the air is attached to a toroidal blade of MIT fame. We get a little bit of the ...

The toroidal propeller, one of the Lab's @RD100Awards winners, has a unique, closed-form propeller design that makes it a significantly quieter alternative to common multirotor propellers on ...

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 ...

Overall, toroidal propellers are an exciting recent development in propeller design, at least in some cases. While they can be more quiet, they won’t completely replace traditional props just ...
