The toroidal propeller allows a small multirotor unpiloted
aircraft, or drone, to operate more quietly than current
drones that use propeller forms unchanged since the
beginning of aviation. By enabling a drone that is less of
an acoustic annoyance, this propeller may accelerate the
acceptance of such aircraft for a wide range of uses—for
example, aerial deliveries, cinematography, industrial or
infrastructure inspections, and agricultural monitoring.
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
