Yes, that is a major problem, I agree... I was thinking of somehow incorporating 2 impellers, one on top of another, both rotating in the opposite direction.
@@nileshgandhi9211 Go see Russian copters. Work the best. You could also use angular rotation for each of the propeller. Since i saw the first Dyson fan i saw it as a propeller.., thanks for doing it !!! Big enough so we can ride in it !!! Use Go fund me.
I just happened to have this exact same idea and did a little research on it. A graduate from Texas A&M University-Corpus had a very similar project but wasn't able to get it flying due to lack of thrust. I think it may because that the bladeless propeller design does better job when at motion. When taking off as a drone you have to stay stationary first which means the entrainment can not be established. Whether it can achieve a 15 times air multiplication rate during take off is very questionable. I am very interested in this project, please keep it posted and good luck!
youre going to try to convince me that an internal wind going in the wrong directions is more efficient than an outside wind in one direction... youre insane.. leave your science degrees on the floor at the door when you leave reality.. try farming ag
@@johnnyllooddte3415 If every time you don't understand something, you call it insane, you will never learn anything. You can go look up Dyson's Air Multiplier tech yourself. But basically, if you have a Dyson fan or hair dryer, you will know the wind it creates is much stronger and straighter and more direct (blows further) than your normal fans or hair dryer with similar size and wattage. That's because other than the wind created directly by the internal blades, the duct design will also draw in more air behind it which creates wind indirectly, thus increasing the airflow. Another similar example (although not the same design) is turbo fan vs turbo jet, even with the same power, turbo fan is much more efficient because it's utilizing more air around it to increase thrust "indirectly".
Your idea is brilliant. Right in front of our faces, and no one thought of it. One thing though. Don't use Dyson in any of your ads. You may not hear anything now, but if it really starts to sell. They will take you to court, and you will loose. Just call it a bladeless drone. Or something that it reminds you of. Stay safe. There's greedy people everywhere. 🤔🤔🤔👍😎 Idea just came in. You know those vacuum cleaners with the strong suction. The ones that can hold a bowling ball. Well reverse the flow, and see what happens. If it works then all you will need to do is to get it to go in different directions. That's just for now. If I do come up with more. Just look at the comments. 🤔😵💫👍😎
Thank you so much for your comment and suggestion! I have since realized that this design needs more changes/upgrades to be effective though! Thank you anyways..
Nice one. but the torque at the center keeps this drone keep rotating. you need to find a way to cancel out the torque in order to fly stable as conventional drone does.
Remember something similar in an Australian patent from the 80's, that didn't work. But now the Dyson tech was better developed, who knows? Try and build one.
A regular drone use the side thrust from four propeller to change direction, two of them spin reverse from others make the drone fly statically. This design using only one propeller to compress air, so the gyro effect will make it spin and swing around. The idea was really good, but the compressor must have two propeller spin in opposite direction to void the gyro effect. Therefore , the speed of each propeller must be controllable, we can use the gyro effect to control the direction of the drone.
I believe the military did a similar experiment with a small one meant personal transport in mind using the same ring shape. Unfortunately the project was scrapped because well the platform was very stable when they attempted to make the platform move quickly they found the aerodynamic properties of the ring caused it to try to self balance every I believe the military did a similar experiment with a small one meant personal transport in mind using the same ring shape.

I saw comments about the lack of anti torque. That happens if the propeller has to accelerate. If not then once it is up to speed it wont have any issues. I am not sure how the design will work but if you have the prop spinning at its most efficient point and then recirculate the air that is not pushed through the valves you dont have to worry about the torque effect. BUT you ll have to worry about an other huge thing...Angular momentum. Though that could be overcome too with some clever programming, and actually use the inertia effect to the drone's advantage. And an other problem would be the Yaw, which can prolly be solved with accelerating or decelerating the prop. I would seriously love to see a prototype of this.
@@TheRattleSnake3145 your comment is a waste of internet resources. How about you try again and make it a better one so we can have a civilized conversation about this cool concept?
The impeller will be experiencing a degree of constant drag as it spins, so even if it's up to speed it will still be imparting a torque force as it spins. They either need to counter this with two counter rotating impellers or vectoring thrust
You have to build one to check that it will really work. Theory is great, but will it produce enough lift? One thing you already have wrong is the amount of air to each unit is too small. that needs to be increased by quite a lot - which should not be a problem as it would make the unit much stronger in any case.
Bladeless is false. They still use turbines to generate the air flow. So this was be thrust. And the effects of the boundary air that pulls more air through would be minimal since thrust need force upon a structure to move it. Why do you think bladeless fans dont just fall over. The only benefit would be that the drag on the fins or whatever the rings are could. Would be reduced. But you wont lift a pack with it.
I don't see that prop holding up to the rotation that would be needed, and if it did surely it would deform. With the tight tolerances needed to make this work any deformation of the prop would likely seize it up or outright destroy the thing. At least with the possible weight savings you might get away with a metal prop to resolve the issue of deformation in the short run, however I still think the speeds needed to achieve a usable device would likely lose any benefits from possibly going to this design. Would be cool to try though.
like the ingenuity but a big problem with the dyson fan and this is the inefficiency of the design. there is a reason props have been used for over 100 years its far superior but dont let that stop ya its still a neet design and would have a market just dont expect leaps and bounds in performance.
How would you steer? With a central intake you can't increase airflow to a fan, only restrict airflow with a valve. Also the rotation of the intake would make the whole drone spin unless you add a counter spin somehow. If it worked it wouldn't be very high performance.
That's nice as long as the temperature is not too hot as to reduce lift and this sytem would likely be defeated by rain or snow. It is a wonderful concept but I would like to see it in adverse weather conditions. Seems that, with rain, the air flow could be diminished if not stopped entirely.
Nice idea, but from aerodynamics point of view, it does not make too much sense. Propellers are efficient as they impart a small velocity change to a large mass of air. The theory states that the loading on the propeller disk needs to be as much as possible constant, so the stream-jet has no velocity gradient within its volume to eliminate/reduce turbulence which is just energy loss. Your device creates a lot of turbulence to en-train more air, this is actually how the dyson devices work, and exactly opposite of what you want, as a lot of energy will be lost in turbulence and not used to create thrust. The 'zen' of aerodynamics of propulsion is to disturb the air the least.
You're trading some higher pressure air for more lower pressure air. Trying to basically use an ejector for thrust seems to violate conservation of momentum, as ejectors are pretty bad at it. The energy lost at low pressures is surprisingly high... And the air moving through those tiny strut things and valves will only make things worse. That's my prediction anyways...
You need way more airflow to generate sufficient entrainment. Only a jet can move enough air for this to work, which is why Jetoptera had to partner with GE Aerospace. Now, they have a noise problem. However, there is another way to use bladeless fans without crazy amounts of airflow and noise. It just hasn't made its way to RUclips as of late 2024.

I think you'll find the same problem others have when trying to use entrained airflow in this manner: works fine for vertical motion, falls apart when you start moving sideways
This technology was in use in at least the 60,s where working in any enclosed space that required serious ventelation, such as a fuel tank, was ventelated by a compresor blowing air through a half venturi ring that resulted in massive airflow. So dyson did not invent this effect, he simply used it.

You only need 3 of those arms when its an impeller drone.. but I guess you should have one impeller at the bottom as well rotating the other direction or something for stability and to counter spin
Nice but do it fly???...... what's it's thrust numbers in comparison to its propeller mode? ..... How long it's battery last in comparison to propeller models?
The propeller blades generate a lifting force. That blades can be rotating or standing but are blown by incoming air. It is the basic an aviation physic principle.
I tried this but it's not working due to the weight of centrifugal compressor weight and motor user to rotate compressor alow incresing weight if we place panitary gear box it ingreaser weight and also have to consider weight of electronics
Great in theory, But in practice I don't think battery capacity will be high enough to generate the required RPM for the intake fan. I'd like to see an experimental model though.
I am not an expert but something tells me that accelerating air trough those rings by high speed air jet will not add any extra lift at all. The only thrust will be produced by those high pressure rimjets. The rest air does not provide any action/reaction support for the body of the aircraft.
We got this for the toddler room ruclips.net/user/postUgkxdzUap46p9ViXhKZf5mK_bXOb89EHxTqq because of the bladeless feature. Actually has a lot more power than I thought it would. Can still feel the air moving well 6 feet away, which is farther than I would expect from a desk fan. My daughter dropped twice and still works. I haven't checked out how long it lasts on a charge yet, but the air output was still good for the few minutes it was unplugged. My daughter also likes the color lights feature, but I don't really care for it and can be annoying to go through all the options before it turns off. Overall, happy with the purchase, especially for the price
And how do you control yaw? A conventional drone adjusts motor speed on opposing rotating propellers to do this. If you use two counter rotating impellers in your design, you would still need to control their individual speeds to control yaw.
i was thinking of a similar design yesterday but this was better than the one i had in my head. Do you have any plans to build it, Would be very interetsing to see how i works and also hear the sound difference. Also keep in mind that you will need to be able to rotate the dyson circles to yaw the drone since normal drones throttle pairs of counter rotating propellers to induce a yaw torque on the drone. Will not be possible with only one mounted center fan so therefore rotating the dyson circles will be nessiccary.
Yes, thank you for the suggestion. There is a lot of scope for improvement on the drone design before I actually build a prototype. Will surely upload my results if and when I do so!
You Wana do it reverse like 4 turbines outside sending air inside as Dyson style etc. SpAce on middle can be bigger in diameter etc. I believe it will be better design. I have few UFO style in mind that will definately worth asking upon.
you are chasing an impossible dream mate, this is just like chasing free energy projects, similar experiment cost me my reputation as engineer on year 2006 for an Australian project. I discouraged you discontinue this project, this path ends in madness.
The math says this will work, but that it doesn't scale down very well. Just a guess but I'd say you'd need at min a 3" or larger impeller. So if you prototype this, make sure you account for this in your testing. Your valves are what intrigue me. Curious to see how they work.
youre going to try to convince me that an internal wind going in the wrong directions is more efficient than an outside wind in one direction... youre insane.. leave your science degrees on the floor at the door when you leave reality
So it's not enough for you to just disagree with me, you need to insult me as well. That says a lot about the type of person you must be. For the record, I have no interest in trying to convince you of anything.
Great concept for passenger drones. With one motor weight can be reduced. The ducts can be super lightweight (I'd probably do carbon fiber over plastic or liquidmetal) since they don't have to support the weight of fan motors. Can even add wings with openings out the bottom for vertical and then redirect air out the rear for forward flight pitching with the ducts under the wings and rear of the craft.
Not quite: like quadcopters, it doesn't necessarily scale since rotor-area is 2D while volume/mass is 3D. Also: dyson suckers are prone to objects in the middle e.g. fuselage. Also: hovering low over the ground - the ambient air wouldn't be sicked in and tossed.
You’re going to need to control air flow to each of the ducts separately to aid in directional control. Then each duct will need to have axis control to deal with the torque of the main impeller and deal with the airflow disruption caused lateral direction flight. This concept adds more problems than it solves. This concept doesn’t scale up well at all. Look at the harrier jump jet. It must run at near full power just to hover. This is why even in the year 2021 we still use bladed rotors to provide vertical lift and directional control.
Cool idea, but wouldn't you want low pressure above and high pressure below? How would it thrust the drone upwards? Would'nt this just suck air through instead of pushing the drone upwards? Anyways, keep creating stuff, looks cool.
Taking a existing design redesigning one part of the whole should be about efficiency of that part, when its not consider redesigning the whole. I don't know why you would take a conventional drone model and replace just the motor/propeller with what at amounts to ducts, and expect the drone to be stable, let alone fly. The four motor design of a drone is specific to the characteristics of the 4 rotating propellers and the torques they cause on the airframe. With one central motor, the entire airframe will now want to rotate around the propeller (arguably impeller may be more correct) I supose you could use a counter rotating setup to get around this, but then there are the huge losses in the 4 ducts... and they are no longer necessary. Why not just direct the propeller's air flow staight down, and control pitch and yaw another way.... There are numerous issues with just replacing a drones motors/propellers with air ducts. Great effort on the video, but its a design that just doesn't seem feasible nor practical.

I like it...make one and change thte world!
yes if regerñ added
You only need 3 of those arms when its an impeller drone.. but I guess you should have one impeller at the bottom as well rotating the other direction or something for stability and to counter spin
Nice but do it fly???...... what's it's thrust numbers in comparison to its propeller mode? ..... How long it's battery last in comparison to propeller models?
And how will you keep it from spinning like a top???
The propeller blades generate a lifting force. That blades can be rotating or standing but are blown by incoming air. It is the basic an aviation physic principle.
I tried this but it's not working due to the weight of centrifugal compressor weight and motor user to rotate compressor alow incresing weight if we place panitary gear box it ingreaser weight and also have to consider weight of electronics
use butterfly close valves
Great in theory, But in practice I don't think battery capacity will be high enough to generate the required RPM for the intake fan. I'd like to see an experimental model though.
diesel test, lets see that shit fly
yea drone prop exíst miteß bater life
I was thinking about it for a long time
Maybe louder the than propellers, less lift?

Dyson is a particular application of the Coanda Effect.
So is this drone a Coanda Effect drone?
I am not an expert but something tells me that accelerating air trough those rings by high speed air jet will not add any extra lift at all. The only thrust will be produced by those high pressure rimjets. The rest air does not provide any action/reaction support for the body of the aircraft.

Where dose the power come from
does the impeller produce enough power so that the air flow is not repelled back from the small area?
We got this for the toddler room ruclips.net/user/postUgkxdzUap46p9ViXhKZf5mK_bXOb89EHxTqq because of the bladeless feature. Actually has a lot more power than I thought it would. Can still feel the air moving well 6 feet away, which is farther than I would expect from a desk fan. My daughter dropped twice and still works. I haven't checked out how long it lasts on a charge yet, but the air output was still good for the few minutes it was unplugged. My daughter also likes the color lights feature, but I don't really care for it and can be annoying to go through all the options before it turns off. Overall, happy with the purchase, especially for the price
And how do you control yaw?
A conventional drone adjusts motor speed on opposing rotating propellers to do this. If you use two counter rotating impellers in your design, you would still need to control their individual speeds to control yaw.
i was thinking of a similar design yesterday but this was better than the one i had in my head. Do you have any plans to build it, Would be very interetsing to see how i works and also hear the sound difference.
Also keep in mind that you will need to be able to rotate the dyson circles to yaw the drone since normal drones throttle pairs of counter rotating propellers to induce a yaw torque on the drone. Will not be possible with only one mounted center fan so therefore rotating the dyson circles will be nessiccary.
Yes, thank you for the suggestion. There is a lot of scope for improvement on the drone design before I actually build a prototype. Will surely upload my results if and when I do so!
How does this drone rudder operate?
You Wana do it reverse like 4 turbines outside sending air inside as Dyson style etc. SpAce on middle can be bigger in diameter etc. I believe it will be better design. I have few UFO style in mind that will definately worth asking upon.
Nice design though the weight and differential pressure might need a solution.
Cool
you are chasing an impossible dream mate, this is just like chasing free energy projects, similar experiment cost me my reputation as engineer on year 2006 for an Australian project. I discouraged you discontinue this project, this path ends in madness.
so you think he should do it then your use of a double negative seems to suggests so ;)
Can improve dramatically the design to maximize efficiency and minimize lots of resistance losses on way the air travels inside the drone!
How does it handle yaw?
The math says this will work, but that it doesn't scale down very well. Just a guess but I'd say you'd need at min a 3" or larger impeller. So if you prototype this, make sure you account for this in your testing. Your valves are what intrigue me. Curious to see how they work.
youre going to try to convince me that an internal wind going in the wrong directions is more efficient than an outside wind in one direction... youre insane..

So it's not enough for you to just disagree with me, you need to insult me as well. That says a lot about the type of person you must be. For the record, I have no interest in trying to convince you of anything.
how does it rotate 360*
Great concept for passenger drones. With one motor weight can be reduced. The ducts can be super lightweight (I'd probably do carbon fiber over plastic or liquidmetal) since they don't have to support the weight of fan motors. Can even add wings with openings out the bottom for vertical and then redirect air out the rear for forward flight pitching with the ducts under the wings and rear of the craft.
Not quite: like quadcopters, it doesn't necessarily scale since rotor-area is 2D while volume/mass is 3D. Also: dyson suckers are prone to objects in the middle e.g. fuselage.
Also: hovering low over the ground - the ambient air wouldn't be sicked in and tossed.
2 years later, yet to see any propless drones. Must not have panned out the way it seemed to ‘in theory’?
You’re going to need to control air flow to each of the ducts separately to aid in directional control. Then each duct will need to have axis control to deal with the torque of the main impeller and deal with the airflow disruption caused lateral direction flight. This concept adds more problems than it solves. This concept doesn’t scale up well at all. Look at the harrier jump jet. It must run at near full power just to hover. This is why even in the year 2021 we still use bladed rotors to provide vertical lift and directional control.
The flow control is in the tube between the fan and the rings.
Cool idea let’s see a proof of concept aircraft
I can 3d print small version if you have files
Wake me up when they make a bladeless helicopter 😴
Is this a dyson (trademark) drone or a Coanda Effect drone?
You will need a fiber gear box and a big engine for enough lift even with your engineer lips on your wing
Cool idea, but wouldn't you want low pressure above and high pressure below? How would it thrust the drone upwards? Would'nt this just suck air through instead of pushing the drone upwards? Anyways, keep creating stuff, looks cool.
Interesting, but a lot of air friction involved.
This is fantastic, BUT, IF IT’s like everything coming from Dyson, nobody can afford it!!
Taking a existing design redesigning one part of the whole should be about efficiency of that part, when its not consider redesigning the whole.
I don't know why you would take a conventional drone model and replace just the motor/propeller with what at amounts to ducts, and expect the
drone to be stable, let alone fly. The four motor design of a drone is specific to the characteristics of the 4 rotating propellers and the torques they cause on the airframe. With one central motor, the entire airframe will now want to rotate around the propeller (arguably impeller may be more correct) I supose you could use a counter rotating setup to get around this, but then there are the huge losses in the 4 ducts... and they are no longer necessary. Why not just direct the propeller's air flow staight down, and control pitch and yaw another way....
There are numerous issues with just replacing a drones motors/propellers with air ducts. Great effort on the video, but its a design that just doesn't seem feasible nor practical.
I had this sim tip of idea for a bladeless drone as well with over bladeless things a long time ago when the bladeless fans came out
Or was it before the bladeless fans came out!!!!!!
When an old child TV programme called the deep were I got same of the idea from
Nice Idea, Yaar! Guten Tag, from Germany. You may send this to Tom Stanton. He could actually build this and see if it is possible!
he already built a hair dryer impeller plane..
youre going to try to convince me that an internal wind going in the wrong directions is more efficient than an outside wind in one direction... youre insane..
