Toroidal Propeller
KEY FEATURES
• Decreases signals in the frequency range to which humans are most sensitive
• Reduces noise without requiring supplementary components that add weight and increase power draw
• Lessens the likelihood that the spinning propeller will cut, catch, or clip objects or surfaces in the drone’s path
• Achieves thrust comparable to that of a multirotor drone propeller
• Allows reliable fabrication with additive manufacturing techniques that make it possible to customize the propeller for various multirotor models and types Toroidal propellers were installed on a commercial drone for testing.

The propeller includes a hub supporting a plurality of elongate propeller elements in which a tip of a leading propeller element curves into contact with a trailing propeller element to form a closed structure with increased stiffness and reduced acoustic signature.

The toroidal propeller, one of the MIT Lincoln Laboratory's 2022 R&D 100 Awards winners, has a unique, closed-form propeller design that makes it a significantly quieter alternative to common multirotor propellers on commercial uncrewed aerial vehicles.

This Genius Propeller Will Change Transport Forever
In this video we look at a new design of propellers known as toroidal propellers. These have been shown to increase efficiency, thrust, and reduce the noise of both boats and drones. There could be many applications for this, such as cargo ships, electric flying taxies, and even computer fans
