A BREAK-THRU 100 YEARS IN THE MAKING

Since Thomas Townsend Brown discovered propulsion generated by asymmetrical electrodes in 1921 there had not been a significant break-thru that allow generation ion propulsion to levels that made it possible to develop VTOL crafts in atmospheric conditions. Our all-electric drone powered by ion propulsion, with minimum noise signature and zero carbon emissions, uses innovative physics principles to generate noise levels below 55 dB.

NOISE MATTERS

Research conducted by NASA found that drone noise ranks highest in terms of annoyance. According to the study, the noise made by road traffic was "systematically judged to be less annoying" than the high-pitched buzzing made by drones. Participants were not told the noise they were hearing was from drones, but all listeners consistently rank drone noise as more annoying than noise from airplanes or delivery vehicles due to psychoacoustical properties not easily modeled or captured by traditional acoustical metrics.

Ion Propulsion Drone Proves Its Commercial Viability

WHAT EXPERTS SAY

Noise is probably the largest limiting factor for the public acceptability of drone operations.

I am concerned that drones are taking to the air without a lot of thought for the ears of people on the ground. Will there be a weight limit on delivery-drone payloads? Who will monitor the sound levels, and how? Should there be a curfew on hours of operation? There must be a reason companies don’t include the sound of the drone in advertising materials – and it’s probably not because they sound so nice. In this ad, the drone seems silent.

While proponents of urban air mobility (UAM) see electrically-powered air taxis and delivery drones as innovative solutions to problems many urbanites face, not much research has been done to address the negative impacts that a UAM ecosystem may present to communities, particularly when it comes to noise pollution.
