I think the big issue with this sort of scheme would be noise. Small, heavily loaded props will be super loud. There are a lot of them in this case. The noise wouldn't linearly increase with the number of propellers but it would increase with the addition of each one.
- FabHK 10y agoFrom the Volocopter FAQ [1] (in somewhat charming Denglish): > DOES A VOLOCOPTER MAKE LESS NOISE THAN A HELICOPTER? > Yes, the Volocopter is much more pleasant in terms of its acoustics due to its design and above all much quieter than conventional helicopters. Listening to the video [2], this doesn't seem altogether implausible - the sound seems ok, like a fan more than a chopper.

- upofadown 10y agoIn comparing the Volocopter noise to helicopters it would be something with no main rotor noise and 18 heavily loaded open tail rotors: * https://en.wikipedia.org/wiki/Helicopter_noise_reduction#Tail_rotor_noise https://en.wikipedia.org/wiki/Helicopter_noise_reduction#Tai... My guess would be that the noise wouldn't carry as far due to the higher frequency but would be very loud closer in, again due to the higher frequency.
- FabHK 10y agoInteresting, could well be. So not a problem for people on the ground, but you'd want to have a good noise-cancelling headset while on board.
