- Опубликовано: 6 фев 2025
- Every year, billions are wasted on inefficient propellers that tear through the air with a deafening roar. But, MIT's toroidal propeller, a donut-shaped blade, turns the roar of traditional propellers into a whisper while boosting performance. Can this strange-looking propeller save the aviation industry half a billion dollars while making cities peaceful again? Could this be the breakthrough that finally makes flying cars a reality in our crowded cities?

A young African man in Rwanda already invented a propeller with similar silent properties for a medical supplies delivery drone he invented some years ago, it's good that MIT has finally caught up...
Yeah I've seen that a while ago they use them to deliver hospital supplies and blood n organs for operations!😁👍
About 15 minutes longer than it needed to be.
I didn't get half-way to 15 minutes. Waaaaay too much filler. It needed to get to the point. I am not waiting for it.
Am I the only one to notice that there was NO SIDE BY SIDE DEMONSTRATION where we could hear with a microphone and see a dosimeter showing the decibel level of both? A whole video about propeller noise without us ever hearing them. Interesting.
The propellere looks great but this presentation is as effecient as the old propeller--I found I could skip the first 9 minutes and miss nothing!
Thx for that 👆🏼. 👍🏼
Yeah, but ...the first 9 minutes are to do with sound, what generates it from propellers and it's impact....I, for one, found it fascinating,...maybe you already knew that stuff... As an old muso, noisy band rooms, etc, I guess you might see why I would!..

Why are there no audio clips comparing the old to the newer style? If what you are telling us is true why not actually show us. I understood the design years ago. This has to be years old and introduced again maybe? Wow thought I might learn something. Intense video style epic fail.
That'sh really intereshting.
GREAT, CLEAR and WONDERFUL EXPLANATIONS, EVERY DETAIL TO THE POINT !!
Maybe STRINGY objects might get caught within the 'open circular' blades ?? Would a SLIT Design - provided at theTangential far-end of the 'circle' allow it to clear itself while revolving ?

Well I don't think MIT invented this I think the patent was filed in the 1970s by some guy I don't know his name but I don't think he went MIT. I could be wrong but I don't think MIT invented this technology
Wouldn't be the first time...
On helicopters the blade angle needs to be continuously altered during each rotation, and on many sailing yachts the blade angle needs to be considerably reduced when the yacht is in sailing only mode. A hybrid sailing yacht will need to adjust blade angle when changing from sailing only to regeneration mode. How will the fixed shape of the
toroidal "blades" deal with this?
Why couldn’t you turn the blade? Just like adjusting a sail. Put the blades on a mount that can move 360
Admittedly a plastic boat prop would not stand the strain, but perhaps someone might try to duplicate a prop using 3d printing.
These remind me of the weird vase thing they found from ancient Egypt, that they have no idea what it is how they made it or its purpose.
gee--- 500 million dollars is a lot of money for a propeller blade.
So, in tests it was 205% more thrust efficient but only 25%~30% more fuel efficient?
Seems an awful big disparity in numbers?
There isn't much mention of the crazy cost increase, it would take decades in most cases to recover the cost of a boat propeller (screw) plus, it has to be specific design for anticipated operation, go faster or slower and they can be much worse than what's currently available.
It's totally unrealistic to be changing screw every week (cargo ships operating at pretty fixed rpm will benefit from correct design, even if they need tugs to get them close to cruise speed)
Might be ok for drones and boats, but aeroplanes and helicopters? I don’t think so
Why do you think that?
👍 Thank you,
Why didn't you show the toroidal propeller in the wind chamber?
I saw another video about this a year or so ago. It was on boat props and the difference was staggering!
The problem? Cost!
A typical boat prop will run about $800 while a toroidal prop is over $7000. I'm not sure of my numbers but either way, the difference is almost prohibitive for recreational boating!
I would think though, that in industrial applications like shipping or military, the cost-benefit would be realized fairly quickly, especially if the prop can be reused once the original ship is being retired!
The range of destroyers etc., would be awesome!
What a waffle padded video. AVOID.
Was so interested. Couldnt handle the ads every 60 seconds
Get an adblocker.
impressive video production
These new designs would be weedless. I welded cupped blades on a stainless steel propeller and the boat jumped onto a plane with very low power and the propeller became weedless. The blade extensions were added to the trailing edges of the blades. I can see that these blades would not pick up weeds.
I've worked in the marine and yacht building industry for decades, yours was comprehensive, I appreciate you😊
WHAT ABOUT REPLACING AIRPLANE PROPELLERS?
What about variable pitch propellers?
Is very complicated in alternative piston engines to manage that efficiently.
they are at best slightly better than a traditional prop , and only slightly quieter ! sad how they`ll leave out facts to push a narrative !
Easy question - Take a quadcopter old vs. new & notice battery life changes.
Australia produced a similar marine propeller years ago.
Absolutely the Taurus is a sacred geometrical form. Of course it’s going to work in plasma better than anything else.
Skip to 9:00 if you just want to know about the new propeller design - the beginning is everything you already know about conventional props.
Just realize that water molecules are more dense than air. Comparing the results to one another is not a reliable comparison.
I wonder what this is for? Water or an air devise...
STILL not commercially available, even for hobby quadcopters which is a huge market. Every one of these hobbyists would try a set.

בהצלחה
The frequency of unsolicited advertising is a punishment for any viewer of this program who does not want to be in a paywall contract.
How do you vary the pitch?
i'mma thinking the 500m is for the initial research. not the actual cost of making the propeller
This has as much chance of being built as the mythical Boeing 797. NEVER.
Ukraine needs this now on their drones.
It seems that these propellers could be very valuable for submarine applications.
Noise! Like advertising!!!!!
very kool
Huey vs a houghs blade speed. Boat props i know. Live near a great lake. Boater. Aviation enthusiast. Engineer in ag. Noise is Huge.
Repetitive explanation, wore me out in the end😢
Reduced cavitation.
Can a device be designed to reduce motorcycle exhaust noise ?
This noise can often be heard for a mile, especially along Lake Michigan.
Well that answers the question of some drone sightings recently over cities, of course the military would have had this for some time??
Start with a twin or more engine aircraft, in case this one fails.
how would one of these props look like with a constant speed or variable pitch configuration ??
This is not new technology and if it was any good for a wide application, long since it would have been a common sight at airports and military bases. This video is just an exercise in trying to draw eyeballs for money.
The production of toroidal propellers can be infinitely speeded up by staged machining instead of the current single operation.
Because less engines over the middle of the ocean is... Good?
Anyone with any knowledge of shock waves and supersonic flight knows this is ridiculous…..
snake oil propeller
it is less efficient than current ones. The Tension Wing is more efficient
RUclips is becoming annoying. Six commercials in the first nine minutes. They need more money?
This is made for boats.
So it is not healthy for Ears, need's 21 min. to tell this, repeating and repeating!
Ukraine could use a quieter drone now !
China has had it for several years. 😐😐😐
You look at this propeller then you go back in time look at what they have discovered in ancient Egypt something that looked very very similar did we find an old propeller that was made out of rock you think of this the things that we see in the past may be exactly what we see in the future how is it there are so many things out there that when we look at them and then we take a second look they look like something that was in the past I wished I could show you what I am talking about but I can’t that’s not what this is about but if you go through ancient Egypt’s mysteries They thought it was something to do with how they drilled holes now I see this and it has a tendency to look more like this. Could it have been a propeller of some sort
Carbon footprint is irrelevant!
Waaaaay too repetitive.
Old technology..victor shau…. Replusing disc
Let's talk and more Tech🤷♂️ video into a snoozefest. It's okay if it's less than 8 minutes long
Pumps
👍👍👍👍
"Traditional propellers create "vortisis" at the tips. Should be pronounced "vorticees"
Stop repeating the same informatiton.
Interesting, but wayyy too repetitive!
Too long. Lots of repitition and padding with not really relevant stuff.
Would have been the obvious thing to do to let us HEAR the sound difference rather than keep telling us it is quieter!
Yawn!
🤦♂️
Why did you use the SUPERSONIC tible to lure viewers into watching the video when there is nothing supersonic about this propeler? NO LIKE FOR YOU!!!
Gee you have to listen to a lot of waffle, next time get to the point quicker.
lol
Bla bla bla
Too many commercials... can't follow the storyline... also needs to incorporate brevity.... I'm leaving at the 6 minute point.

R u listening Ukraine?
the narrator said "It's similar to cracking a wip." I'm sure he meant to say a whip, which is correctly pronounced hwip.
Anti gravitic engines, currently being used by military in USA will change the entire aviation industry, with speeds that will be supraluminal, the above propeller is a joke.
What a ridiculous looking pic!
way to much irrelevant fill
