One of the most promising pieces of the cyclorotor as a propulsion system is the unique and low noise profile. Please, dial back the music on the next video :)
What makes you say it has a low noise profile?
@@NicholasRehm Tip speed is certainly an important factor, but it's not the only one. Wouldn't the design of the cyclorotor make it harder to scale to larger sizes, resulting in a higher effective disk loading and, thus, higher loading noise? Also, the cyclorotor forces the blades to pass through the wakes of other blades (like a contrarotating propeller) which would be a very large noise source. That, and all of the engineers are wearing ear muffs :)
@@gibbled0 that’s the thing: lower tip speed at higher disk loading = less noise.
Frequency content is also very different and arguably more pleasant if we start talking about urban operations
sound pretty loud to me
@@soccerguy2433 yah it sounds like it makes loud music noises.😅
So cool! Would love to see how it pushes the air around. Maybe a display/test with smoke once testing progresses?
I concur. Theater smoke would be, at the very least, visually interesting for us CZcams spectators, and might be a useful diagnostic device. Cleaver idea!
Bit less cringy music and more engine sound and this would be perfect ♡
Well, I love the music :)
Wow. Congrats. Blade Runner esque!
Congratulations! As an engineer and a dad, I am so thrilled to see folks like you pushing the boundaries and contributing to the collective knowledge base. As a pilot I'm especially happy to see such progress in aviation. Such endeavours bring great hope as I ponder the future for my kids! Many thanks and keep it up, so to speak - from Sydney, Dave :-)
y el futuro de los miles de humaonos que viven en miseria, desgracia y se estan muriendo de hambra. con tu comentario solo dejas ver tu individualismo. claro tal ves puedas comprartelo, tal ves tu familia te ayude, pero tal ves tu no ayudes a ningun humano realmente solo a los tuyos.
@@luxwebhostingpro7313 Interesting comment, linking advances in human knowledge to the plight of humanity. Where would we be without knowledge development? Do we cease innovation until everyone is happy and healthy? Who chooses the worthy pursuits over the unworthy ones? Perhaps this technology can be employed to help others in the future? You make a big assumption about me based on my compliment which perhaps says more about you.
Love it! Great job guys! This needs to be turned into a car!
Amazing tech. Please whoever edit your videos, we dont need the music, just your amazing tech and explanations. Thanks
Aren't those basically Voith-Schneider propellers like you find in tugboats?
Their biggest advantage is a very quick adjustment of the propulsion vector. Is not yet visible on this demonstration
But with thrust vectoring style like drones, I think there won’t be that much of use from quick vector adjustment properties of that cycloidal prop. Cuz all the trust need to propel to the ground in order to keep hovering and the vectoring options are only push to the front, back, upward and downward (You know what I’m trying to say, I don’t really know how to explain this more understandably). I hope at least it can yaw without losing altitude because yaw effect won’t work on this.
@@ptixcc314 -- Yaw would be produced by vectoring the thrust of two rotors on one side slightly forward (though still mostly downward) while the two rotors of the other side were vectored similarly slightly aft. Maintaining altitude would thus require a slight power increase
I'm assuming the blades are gimbled so that they expel air down thus changing angle of attack depending on where the are in there rotation cycle, like how a helicopter moves vertically by changing the AOA.
I would like to see the gimble in the endplate next to the motor, is there a gear network in the plate that changes AOA depending on rotational position, is it a static gearing that can be increased or decreased by a yoke?
One more thing, efficiency? less or more than a typical horizontally rotating blade, because the blade spins inside a cylinder you don't have to have a blade with a progressive curve out to the tip.
Clever or just a design experiment, can it be done or breakthrough?
You are correct, there’s a detailed look at the mechanism on a smaller scale version in my newest video
I would assume less efficient, as blade efficiency is proportional to length (if I understand it correctly)
Gimbal each “pod” as in a fully articulated rotor blade system??
For comparison, you can see if you can find an illustration of the mechanism in marine cyclorotors, which are used on a vertical axis to propel ships, especially tugboats. Voith-Schneider makes them.
I don't know if it is accurate, but this video claims to describe the Voith-Schneider control linkage design:
czcams.com/video/bbXyduMyOnk/video.html
Nice! What is the thrust to weight ratio of this system? How does it compare to a conventional quadcopter? How would this system handle a failure at one of the corners?
Or a counter rotating blade set up. Kw/hr in hover mode vs. just that.
One nice thing about the failure mode is that the plane at right angles to rotation axis is actually difficult to design such that it DOES intersect a pilot vs conventional quad blade designs that either need tricky above and below designs or bulky armor between an exploding rotor and your meaty bits.
В случае отказа одного из углов она перевернется и упадет на землю. И будет полный пиздец !
don't forget the huge loss in efficiency due to the low aspect ratio wings.
Get rid of the distracting music.
Distracting? Or just downright annoying?
a vid without the added so-called music would be nice - I'd like to get an idea of the noise the *machine itself* produces.
Your slogan should be "It drives on air!"
Hmmm what kind of wieght can it carry ? Seems those drums are going to have to be alot larger to carry just one person .
future flying car 😵
To be commended with the military option showing possibilities. The amount of parts X 4 is vast ,blade deformation and ordinance strike leave little to the imagination. I feel I am watching a reboot of 100 years ago.
Coander effect VTOL will win
The main value I see with this design off the bat is it's low profile and you might be able to stack them on top of each other for storage. Useful for aircraft carriers and aircraft launching a bay full of drones.
I also see less of a threat from power lines getting caught in the blades, could be handy for civilian rescue craft too in that regard
I wanted to make a motorcycle with pop out ones of those. once I saw Tron Legacy and their hubless design, I was like I bet we can fit some fans in there! I was thinking basically an oversized turbo but I like this better
This is awesome to see!!! I'm working on my own right now, and it looks like yours is running very smoothly :) Do you have any general specs you can share like the weight and payload capacity?
Que negocio sensacional!!!
How much can it lift? This is a huge break through !!!!
The main problem with this build, if 1 malfunctions, the other 3 won’t be able to safely land. Because of that, it won’t go professional / military. It’ll be a cute concept at most, or a toy for rich ppl with a death wish.
If 2 oposite rotors have sufficient thrust to keep it flying, than third rotor could do balancing, and it could keep flying with 1 rotor malfunctioning.
Ejection seats ....
I don't think this is just a cute idea.
The helicoptor is more dangerous than these four rotors if 1 rotor mulfuntion...
But we continue to use it in professional/military.
@@jirayupeetakul8854 Helicopters can glide to land without the engine, same as an airplane. They do this through autorotation. This contraption is not capable of such autorotation. Helicopters, even with one rotor, are safer. The rotor system of a helicopter is also more efficient than this device, and mechanically far simpler.
How do you make it turn in place? I see it can go forward and backward easily as it is, and to strafe you'd need to bank it. But how does it turn? Can you do it by some inertial sorcery with a right hand rule and varying speeds? Could banking or pitching with the combination of motor speed change cause turn? Shouldn't two of the propellers turn the opposite direction to give more control? NVM: I'm silly, you can make it turn in place just by directing thrust slightly to the front on one side and to the back on the other.
Right - it can yaw, but can't thrust laterally. That means that if you're hovering, you need to roll toward the direction that you need to move, to move laterally.
This is so promising . It's neat and most compact way for future electric flying cars .. super love ❤️
a promising land, sea and air vehicle in one machine
It should combined with flexible tail of air jet propulsion system under the main body like jet fighter, so the main body size capacity for loading passenger can be increase, and small jet propulsion around it to arrange the movement.
i hope you plan to try making it hover at arbitrary pitch attitudes.. it should be possible using this propulsion system, and it would be quite the sight
Amazing! Put some rubber on those rotors and we have a real flying car.
Until I watched this video I thought the current attempts to make flying electric taxis and other vehicles with conventional propellers were nothing but masturbation, but this vehicle has made my jaws droop, this is it!
I just watched the future… love it 👍🏼👍🏼👍🏼
this technology has been around for a long time, since 1909 in fact. Tugboats have used this system for decades.
So what are the energy in, power out comparisons to conventional rotors?
That too is something I'd like to know as well. Right of the bat I see it is a low profile vehicle, good for storing aboard aircraft carriers where storage space is at a premium. I also see the ability to fit many of these on board a aircraft and launch them as a drone swarm.
Also, one again to it's compact configuration, it may be possible to launch a version of this from a submerged submarine. (Obviously, much engineering is required for that...)
But other than that I'd not completely sure what they'd be used for unless everyone gets to put one in their garage and we all have flying cars like in the Jetsons.
Impressive! Leave out the music next time; I want to hear how the machine sounds.
amazing!
Was the loud music added to hide its major defect ?
Now cage those drums like a piece symbol and make each of the three adjustable or directional control flaps as well as being the outside supports for the outside of the drums. It will take care of your vibration I know must exist and limits RPM! Just like a box fan with the fan blades spinning inside, by using the walls of the outer box as vent or directional lifting and flight directing flaps you should have a more concentrated force that can be used for braking as well, and with bearing or magnetic outer bearings be more supported and better protected, with the added vibration reduction Seems like a major improvement to a great idea. Just an opinion from someone trying to figure out electromagnetism, Gravity, the Dielectric and Light. May the Aether be with you. Great work by the way!
wow, It looks very stable! Congrats.
I'd like to make a video about it, where can I find more info?
This would be perfect for a hoverboard. Way better than the platform of drones design people are currently using.
Better stability can be obtained by Dihedral, an angle formed by two plane faces. When you add dihedral, you add lateral stability.
this is not a fixed wing aircraft. and it's also fly by wire.
@@SoloRenegade When you add dihedral, you add lateral stability.
@@WolfsburgWarehouse -- Dihedral is for lateral stability of a pair of fixed wings. Similar stability is produced by "coning" of helicopter blades. This is a different technology using balanced thrust generators for stability. Nothing would be gained from any dihedral, and power would be wasted if the laterally-opposed rotor units were mounted to the body at an angle that simulates wing dihedral.
@@shannondror The Cyclo Rotor dips when it's not level.
@@WolfsburgWarehouse -- Both sides of the craft would lose the same amount of down-vector thrust when the craft is not laterally level, while also producing a side-slip. It does not present a runaway roll scenario. However, producing yaw with opposing side fore-aft vectoring would require both sides' down-vectors to remain equal and balanced. Producing roll deliberately via differential lateral power would, however, require care to control the amount of roll and to restore balance.
현대기아는 이 회사에 투자해야한다. UAM에 가장 적합한 공학디자인이다.
Es fundamental que consideren al ciclorotor como algo más dinámico , su diámetro debe modificarse durante las distintas etapas del vuelo de igual manera que el ángulo de inclinación de palas . El otro concepto a abordar es el cambio dinámico de la amplitud diferencial entre el interior y el exterior . Se debe considerar de igual manera que la dirección de cada ciclorotor debe ser dinámica. La idea está en franco progreso
While it's encouraging to see a drone operation that manages to lift its own 83 kg of gross weight, there was no mention of net cargo weight above that figure that these demonstrator rotors might carry. So far this is a net-zero demonstration, not a practical technology demo.
This is all the prototype and testing phase. Amazing this proof of concept is able to hover with that kind of stability!
@@nighthawk0077 -- Now why should a drone with 4 identical propulsion units mounted at the corners of a rectangle ever be unstable, unless the units don't actually produce consistent thrust? Hovering drones are not uncommon at this stage. The must important demonstration here is the effectiveness of the horizontal articulating blade configuration -- that it provides controlled thrust without tearing itself apart, especially as the direction of thrust is modified by what may be as simple as a tie-rod. Traditional drones can only vary the power of each prop. But these units can vary its direction while maintaining constant power. Regrettably, this video did not demonstrate much of the maneuvering capabilities or methodology.
@@shannondror This prototype has already gone through several iterations with many design and system changes made along the way. This is far from the first hover test, however it is one of the first successful flights.
This is awsome, the ultimate drone!
Those are like fans found on a Vornado Fan its a good design choice to use those instead of propellers. Just from a design prospective try using them sideways instead of out ward like wheels you can make them longer this way and get more airflow. I'm not an engineer but do like design. BladeRunner flying cars will use this type of fans imo.
Does it fall from the sky if one rotor fails?
wright brothers invent flight, then a century of like sameness, and then suddenly this explosion of innovation. Cool! energy density breakthrough makes it all possible I guess
much of this tech is older than you think. Innovation in aviation has never stopped, you just don't see what has been going on the whole time. This tech, form of propulsion, first appeared in 1909.
@@SoloRenegade fair point. However I do think the point of stagnation developments in altitude capacity and speed have been made by Burt Rutan and Elon Musk independently as examples of general lack of innovation.
Woooow a Blade runner spinner :D :D :D
How much weight can it lift?
Yes
Congrats guys! This is amazing. I have done some designs based on your propulsion. Can you provide me a contact where I could share the designs and get feedback?
So cool....
Amazing
Lehner motors (LMT) the best in the world! I also use these for my RC boats
Congratulatios!!! Great test.
Need This Applied to DCL Maned Vehicle! Race this thing! Race it or die!
Voith Scneider mechanisms... they work well in the water ... and air it would seem.
God favors this design 😎
Cool! What happens when you strap 250 lbs. of barbells to it?
It answers "bro, do you even lift?" with a Steven Hawking voice..
@@n00ki 😂😂😂
They say it's driven by four hamsters.
Post more videos. This machinery is good
next big step #FlyingCars
There's no advantage over using regular old propellers. It's not more efficient, not quieter, definitely not lighter...so, why ?
What's the actual noise level? Is it possible to reduce noise level with larger dimension 'fans', at a given lift capacity?
I also am curious about that
I was raging about some shortcomings of this rotor on another channel until I realized...it's not even the original channel
Finally we can have Star Wars Speeder bikes! #PutASeatOnIt
Should try to put this tech on a Tesla instead of wheel, I am sure it can work as a safe fly car
We have a Spinner from Blade Runner... nice.
It looks like a formula 1 car without tyres !! Maybe it could take over from cars. ? Great design
Such wonderful progress towards this old but much saver technology than rotor blades on helicopters.
R u sure it is safer, not just cheated by its looks ? What happen if human touch those high speed rotating wheels ? If blade slices, this will roll a human, i think. CMIIW please.
You could wrap some titanium mesh screens around it, like an 10 or 20 mesh.
No need for torque countering tail rotor. How does it do on auto rotation emergency landing? Can it handle one rotor inop and maintain altitude or at least do a controlled drift down? How about forward speed limitations?
@@maryfrawley4388-- Aerodynamically, autorotation is out of the question, because the blades are not within the external slipstream; but a single rotor failure should allow a controlled descent using the remaining three.
@@haditjandradjaja8403 Word to the wise: don't touch them but a shroud can be built around them to protect birds and people with erm... itchy hands.
wow new ways for a drone
So, what is better? To have vertical quadracopters like in helecopter or horizontal cyclocopters?
Free flight, this a tethered flight, and it's from back in August?
the tether didn't lift it or restrain it. it flew on its own power and control. but with a safety line incase anything went wrong. The tether never went taut.
The SAFER of looks to an Industry
How is the efficiency compared to a propeller with similar performance?
I love this, I really do. But the drawback is, a small failure would be a critical failure.
True, the complexity is scary. A helicopter has one complex cyclic pitch control mechanism per main rotor; a multi-rotor has at most a simple collective pitch control, but on multiple rotors. This has multiple rotors, each with a complex cyclic pitch control mechanism, and they're all critical!
Impressive !! 👍👍👍
Awesome . Well done.
Consumption of power / km " flight " ?
Love this!
How does the steering system work?
Wow.
Amazing! What I want to know is how does the thrust know how to go down?
Looks like variable pitch blades within those barrels
You need to watch the videos on their website which show the theoretical structure and how the control point is shifted to bias the direction of thrust.
Voith-Schneider mechanisms. They run well in the water... and air it would seem.
@@paulbergin4239 -- This raises an interesting question. This demo was for an aerial vehicle. But I wonder how would this design respond to water? Could this vehicle land on water, propel itself to land, and subsequently lift itself out of the water to take off? Or are the rotational speeds required to operate in each medium too different?
@@shannondror Air and water are both fluids. Submarines have the same control surfaces as airplanes for that same reason. At small scale, you could possibly do both underwater and air as many quadcopter drones have already done. But as size increases this becomes impractical.
How heavy is this thing?
What's the reason for the cut in the video between spinning up the rotors and the liftoff? 🤔
Since it was a test flight I'm certain there was a long period of monitoring and calibration before liftoff and they didn't want to bore us with it. If I edited the video I would have done the same.
@@ikannunaplays that makes sense, thank you.
The future is,,,, HERE
this is 1909 technology
@@SoloRenegade -- Depends on what you mean by "technology". The materials needed to make this mechanism work effectively, efficiently, and durably in air were certainly not available a century ago, though a version of the basic design was implemented in some watercraft that long ago. The design of electric motor tech has likewise advanced significantly. So, really, it is not 1909 technology at all -- only the concept dates from 1909.
@@shannondror You are correct, but the innovation is old, and many people have experimented with this concept over the past few decades.
I've already viewed this video, and then been suggested it again by CZcams Recommended. I then marked it as Not interested AND told CZcams that I've already seen the video.
I'm now watching it a second time because it continues to appear in my Recommended feed. I will mark it as already viewed for a second time, and see if it reappears.
It is working,... now how to improve it.
Looks amazing! But with pure downward thrust, does it have any yaw control? If so how?
From what I've read the drums can produce thrust in the full 360 degrees of rotation.
Thus they should theoretically be able to increase thrust along the horizontal axis in one quadrant and reduce it in the other to produce yaw effect.
@@ender5817 correct
Please, for the love of engineering, STOP PUTTING IN MUSIC
Congrats
Cooles, geniales Ding, aber die Musik bitte ändern.
In cyberpunk 2077 game, there's flying cars , could u build those
Awesome 🤙
Cool tech. Please. Stop with the loud music in your movies. Your tech level doesn’t need it and is only distracting.
very interesting solution would like to discuss more in connection to INDUSTRY 5.0, which I am the FOunder of. How the direction is being changed?
Please keep hands inside the vehicle until turbines come to a complete stop.
I’m gonna need that come up on the dashboard screen for ninnies 😩
Awesome but just like the drones, I don't like the noise. Imagine them running all over the place and making loud noises all day.
I also hate mosquitoes buzzing around my head trying to sleep.
Cyclorotorcycle!
I'd ride it
Thats why my washing machine wants to move always it have same physics than this have XD
This is a really smart design. Can accommodate in an aircraft without compromising it's aerodynamics.
Would the engines produce forward thrust in the same position?
Apprantly it's Omni directional from what I've read.
Yeah many questions . Very cool though
@@pippy4658 I don't get what that means, if it was onni directional at once it wouldnt lift up, so it needs to be able to vector the thrust some how
Each rotor can thrust in any direction perpendicular to the axis of rotation, so in this design with all rotors on lateral axes, they can all thrust in any direction up, down, forward, or backward... but not sideways.
@@cinialvespow1054 in this context, "omnidirectional" was intended to mean "in any direction"; however, cyclorotors can't thrust in along the direction of their rotational axis, which is lateral in this case. The rotors are controlled to thrust upward for lift, and upward and forward to fly forward, etc.
Yes the music makes it seem like a game launch, probably added by someone in there twenties. But excellent product
Or by a Boomer who likes to make generalizations about other demographics ;) their*
Would like to work here if possible...
