I'm naming it the "wishbone" propeller. You heard it here first.

[@thebeyondofficial]

😂

[@maestromaestria7564]

That actually suits It so well

[@zavatone]

The pulling forces on the rotating mass for that will put lots of stress on the motor bearings, shaft and additional rotating items unless a counterweight is added.

[@DaveSmith-cp5kj]

Noise reduction is important for military/police applications but for commercial drones I think the biggest issue is not noise but security which no one seems to be bothering to address. Especially if you are delivering expensive items.

[@BobsVagene]

Cameras?

[@bouvardc.2334]

Noise is very important for civilian applications too....

Just encrypt your transmit and receive signals. If you can load an encryption key into your transmitter you should be fine.

[@derp195]

Nobody is talking about it because encryption is easy, and the weakest point in security is the fact that *packages are left unattended on your porch.*

[@you.got.gapped.racing44]

In order to make the propellers silent, you must reduce the wake or turbulence caused by the propellers, a standard blade’s endtips produce a lot of wake, a toroidal propeller eliminates the need for an end tip, meaning that the wake is basically removed, but as we see in the new era of formula one cars, the rear wing appears to have no end plates, which reduces wake, and also reduce downforce efficiency, to the contrary, the 2017-2021 formula one cares had more boxy and turbulence causing rear wings, they were consistently more efficient and made the cars quicker, similarly, having an endplate on the end tip of a propeller is enough to not only reduce the wake but also give the propellers more lift, which yes still makes them more noisy, but making smooth ridges that go parallel with the airflow on the wing is enough to clean up the airflow enough to give a balance between having optimal efficiency and not being a noisy inconvenience, and some noise is generally good, because this is enough to alert us with them.

[@christianmoreno7390]

Hello. Are there any 3d print files for this zipline propeller design??

[@patrickschlauch6638]

You forgot to mention the most important advantage of the asymmetrical design of the Zipline propellers, which is the reduced drag when not in use while the drone is moving fast in forward direction with the rear propeller and wings only.

[@stug77]

JUST..... just make the rotor larger. This will reduce the frequency of the noise and thus make it quieter to humans.

[@m14srv]

Right so the next upgrade should be attaching the 2 blades into a single toroidal shape and maybe extend the head of the counter weight to be wider

[@capbarker]

There was once a time when passing commercial planes would be deafening to anyone on the ground. Nowadays, while planes are far from silent, you can easily continue a conversation (even where i live next to an airport) I'm looking forward to seeing how these delivery drones progress. Will they have to have traffic-type systems once there are hundreds in the same airspace? Will illicit goods become more easily delivered by blending in? What unforeseen problems will we find?

[@RynaxAlien]

Which is most power efficient at lift? Cycloidal are too expensive?

[@videorowtv5198]

How about just using ducts to eliminate the tip vortexes?

[@TK8866275]

I wonder if it's possible to improve unequal zipline propeller by connecting the propeller tips like in toroidal design. If ring shape of toroidal design eliminates turbulance caused by air flowing over the tip like in traditional propeller it might do the same also in zipline.

[@MgNoobie]

Yeah the impact is during war the quieter the deadlier

[@Flesh_Wizard]

The war impact will be the grenade delivered to the enemy

[@jimmyzeng998]

can you like at least cite your sources, like I know one of them is action lab but can you cite all of them?

[@Larsbor]

If these soundproporties can be carried over to big industrial windmills …. they might be less opposed in their environment, and help electrify and make clean energy in the future.

[@whysoloco]

Someone has to make it 3d printable for DJI mini Drones

[@kaf2303]

[@willyd1711]

Interesting to consider other uses for quiet propellers. Like paramotors! @TuckerGott

[@jeffcauhape6880]

This is brilliant

[@MrNeilandio]

How about an unequal toroidal propeller? Would that work?

[@dennylukman1801]

Wait until that prop design gone mainstream. Imagine ww2 bomb dropping on you without the tell-tale wind whistle from the bomb.

[@therealdohos2607]

its sad that we had to wait til they figure a way to silence drones to get aerial pizza deliveries.

[@KidCe.]

toriodial propeller on racing drones? nah man, not a single fpv racing drone uses these

[@simonci5177]

Why this blades are not in all drones now. Like in DJI or on the planes? Of for DIY drone builders

[@Ryurex]

new technology and probably they patented the blades so they'd require a license to sell, use and distribute them commercially

[@Ryurex]

for DIY drone builders there's already people reverse engineering blades them on youtube but it's a lot of trial and error, if not printed precisely as intended it will blow itself up.

[@spencera3075]

Um… When it comes to police and life flights, noise takes a back seat to performance. Now commercial uses I could see this becoming required.

[@izjusme9504]

Why does the zipline drone have five propellers? Doesn't that provide a torque bias?

[@RaghunathTambde]

It is a safety provision, if one propeller stops working the fifth propeller acts as a substitute, but if all are working fine it works as a speed booster pushing the back air

[@blakes8901]

assuming enough thrust headroom, any torque imbalance can be compensated for using software, with potentially a small loss in overall ability and performance depending on the situation

[@beginnereasy]

Use a centralized intake and pneumatics to spin the propellers... not four unique motors 😂

​@@almor2445 genocide? Have you any proof about that? What you know about Donbass region?

[@Wonders_of_Reality]

​@@СергейПипенко-д7ь Reminder: everything started in 2014. Russia annexed Crimea by organising rigged elections controlled by their military. At the same time, Russian bandits and some collaborationists instigated by the former FSB agent and terrorist Strelkov took over Lugansk and Donetsk regions. In the process, they tortured and murdered everyone who opposed them. At that time, the infamous Russian phrase отправить на подвал (send to a basement) was born. Needless to say, the “elections” organised there can’t be called fair and democratic in any way. I recommend reading some articles from “Guardian” if you want to know more. Long story short: It’s all Russia’s fault. Back to the topic: such drones could indeed be helpful for a more stealthier approach. At least some experimentation is worth trying. Maybe it turns out right now that speed is more important than stealth. Who knows.
