This Propeller will Change Aviation Forever!

This Propeller will Change Aviation Forever!

These strangely shaped twisted-toroid propellers look like a big step forward for the aviation and shipping businesses. They are much quieter than regular blades, both in the air and on the water, and they are much more efficient. The purpose of a propeller is to move a material, usually air or water, by making it spin. In some ways, they are different versions of the Archimedes screw, which was probably used in ancient Egypt hundreds of years before Archimedes wrote about it in 234 BCE. But when it comes to rotating devices, there haven't been many big design changes in a long time. For example, propeller-driven aircraft still use twisted-aerofoil bladed propellers like the ones Chinese kids played with 2,400 years ago, even though they aren't much better than the wooden propellers that the Wright brothers made in wind tunnels in 1903. Screw-shaped blades are still used on boats, and some of them date back to the 1700s. So it's interesting that a couple of groups say they've shown that a very different shape works better in both the air and the water. Specifically, they say that strange twisted-toroid ring shapes are both much quieter than traditional designs and so much more efficient, especially in the water, that they could be a huge step forward.

This propeller was changing aviation forever, back in the 70's

[davidkamen]

If equipping an aircraft with one of these propellers, how would you "feather" it in the event of any engine failure ?

[jamesjacocks]

I would say propeller technology has come a long way since the Wrights. This propeller was thought to be quieter and more efficient but it was just about a wash as to those parameters. That was the conclusion back in the Sixties and Seventies. You can still find these propellers, on mixers.

[guntharreform]

Concerning fixed-wing prop planes, how would you feather the prop to prevent drag, should the prop beccome disabled?

[fuelban]

Incredible stuff, this revolutionary design will give birth to a whole new spin off of concepts, .... I love seeing revolutionary designs.. and this one is exceptional...
Love the video... Extremely informative and interesting video thanks...

I'm far from an expert on the subject but Aviation is one of my all-time favorite subject hats off to the engineers they come up with these designs and if you look in the beginning of the history of Aviation and down the years some of these ideas were thought of but we're ahead of their time and at the time they might not have been perfected but with the technology we have the computing power ideas and dreams someone invented back in the past are coming to fruition now I think it's just great. I got my love of Aviation from my father he was a pilot on a B-17 during World War II boy I miss my father a lot the things that that man went through and all the missions he completed during World War II in Europe when he was on bombing missions over Germany I can only imagine I remember him telling me that the anti-aircraft and the flag from the anti-aircraft bombs exploding in the air looks so sick that you could walk on it and I have a picture of my dad's with his best friend Captain Maddie standing next to their bomber with holes and bigger giant trash cans curled up at the top the metal was curled up at the top from the anti-aircraft exploding under the wing anyway my gas Gilbert Martinez was one hell of a man and thanks to him I learned to fly I got off subject but I remember my cat telling me of all the Innovations happening in aviation during WWII just reminded me of this new propeller design they have things keep progressing straight knowledge is just great

BUT :How do you change the pitch of these toroidal propellers on a Turbo Prop?

[captainscarlett]

I wish I was an aero engineer. Toroidal turbine blades? There's an idea.

[reeda]

Would this propellor work in a waterjet boat?

[martinsaunders]

Forgot to mention the private flying car that millions of Americans have eagerly awaited for 70 years. 😂

[Igors_mind]

What are the numbets??
For boat propellers there are numbers.

[timmccrory]

What about airplanes that have variable pitch propellers in order to take advantage of thinner atmosphere, higher engine speeds, and Fuel and air mixtures. This type of propeller would be a non-starter.

[Bob_Adkins]

It has the Internet all aquiver but isn't moving many boats or planes.

[burntsider]

I always thought the powerhead produces the noise from an outboard motor. Is the noise from the submerged prop really a factor?

[metatechhd]

🤔🔊💭 It's an intriguing question, and the answer might surprise you! While it's commonly believed that the powerhead is the main source of noise in an outboard motor, the submerged propeller does play a significant role in generating noise. 🚀🔊

[zeekwolfe]

If this was so good defense contractors and even outboard motor manufacturers would have long-since made use of this design. They have not, so what does that say about this new propeller?

[SovereignTroll]

Bird strikes and hail hit hard and will exclude these. Today"s propellers are optimized.

[johnarnold]

This type of propeller has been patented 150 times in the last 120 years.

[hornplayer]

It is not new! If this design was so great it would have been adopted world wide years ago.

[donaldgrant]

Well in an airplane you have to remember the more power the propeller puts out the more torque it puts on an airplane in the opposite direction. So I don't know if this will work that well on an airplane. If you've watched the movie about the friend in the Korean war that crashed his plane to save a friend, who was black, When the pilot that was scared of landing was coming in and was short, he hit full throttle and spun into the water, well that is about what this propellor on an aircraft might do.
