Bladeless (Propeller-less) Drone Concept  

Perfect solution for a RotoDyne air craft built with fiber pultruded plastic. The rotor blade tips would have the blade less fan ducts. Could even have counter rotating dual blades to amplify the lift powered by these bladeless fan ducts. Craft would be electric.

*This fan is everything I wanted in a desk fan and more. It looks great for **Fastly.Cool** my room , it puts out a wonderful amount of air. Is very easy to use.I just keep it plugged in.*

There is 1 major problem!!! There is no provision for anti-torque. As is it will become a spinning top.

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!

That motor and compressor has to make some serious torque. I don't see how yaw control is achieved either.

Damn that's exactly the theory I was thinking about before i googled it

i literally came up with the same idea on my own, i looked this up to see if theres something like it and it's exactly what i thought of

Nice theory.Get back to us when we can see it flying

So they put Dyson vacuum technology into a drone very smart

That design was originally created by a Mexican Engineer, his design won the award in Singapore. Hope to see more ideas like these.

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.

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.

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. 🤔😵‍💫👍😎

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.

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.

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. 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 cause it to try to self balance. When it would tilt in one direction and begin picking up speed the pressure on the back of the ring would decrease and on the front it would increase forcing the front of the wing to tilt backwards does preventing the platform from maintaining its angle and speed

Use axial flow fan for more airflow. And make the inner part of the wings curved inside like a spoon.

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.

A new breakthrough of propulsion system!

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.

Definately the way to go for drones and pilotless taxis. Good work.

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.

Wouldn't there be a lot of gyroscopic precession sure to the single rotor in the center? That might make it be constantly working to counteract it

Nice idea, but it will very hard to flying cuz low air preasure on bladeless chamber, and it has 4 🤦

Only issue is how would it turn, since drones turn by using all 4 rotors in the same direction, which wouldn’t work for this if it was 100% dyson

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.

Great concept. Just need to worry about countertorque. Can solve this with a second counter rotating prop

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...

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.

I believe that if you force the air to spin at the ends in the opposite direction to the rotation, you should solve the turning problem

This design has one propeller at the center. It'll spin. The drone itself would spin with it.

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.

Why is the same music showing up on every video about a new device concept that has no prototype?

gonna need to gimbol those ducts to fight the gyroscopic torque of tha impeller. That, or put a contrarotating impeller in there somehow to counter it.

It's a interesting consept and I would love to own one, but it really would not bet that effective.

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.

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

Hi, what a nice idea! I would love to look more into the feasibility into this concept, did you find any academic papers for this when doing this project?

I like this. This could make a manned flying jet pack using two bladeless fans and a lever to angle the fans slightly for forward/reverse thrust. Shift human body CG for turns.

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

I like the idea, *lets see it Dyson!*

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.

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

Just a Big Dyson

I cannot want to try out this baby

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.

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.

Wake me up when they make a bladeless helicopter 😴

I love it but where does the flight controller, esc, radio rx, and battery go? How much does the whole thing weight?

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, looks good on paper and CGI, but like the Dyson fan, it's grossly ineffective.

Our future aviation

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.

Nice design though the weight and differential pressure might need a solution.

WOW!!!!!! THIS IS ACTUALLY REALLY INCREDIBLE IDEA

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

Wow it's so cool

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.

Won't the impeller still suck in bugs; and then become a blender, building gunk from all the shredded bugs inside it over time?

This is fantastic, BUT, IF IT’s like everything coming from Dyson, nobody can afford it!!

And how will you keep it from spinning like a top???

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.

very cool idea ! I look forward to your proof of concept. I hear there is great promise in This field.

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.

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 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.

Can't wait to see the result of this concept. Great idea.

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.

where is it?

like it, ¿how will you counteract the big turbo? ¿can you please use tangent ducts instead of perpendiculars?

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?

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!

2 years later, yet to see any propless drones. Must not have panned out the way it seemed to ‘in theory’?

How soon will we be flying vacuum cleaners?

Before you start this idea, you have to study the working principles of Dyson fan carefully. It actually can't produce enough thrust and your drone won't fly.

Cool

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.

Could maybe make this with a 3d printer

Need two impellers to offset rotational force from the impeller. Would spin off

prefer 4 fan then 1 fan. i dont think that single fan have lift force enought.. more big the fan, less rpm its get.. also using valve is expensive, and heavy.. then housing for that big fan is good for battery, mainboard, gyro or camera. try design it, more simple to manufacture. less component, less waste. now 3D print a prototype is easy. everyone can have one, and build final version with import component. its cheap and make that drone affordable.

We got this for the toddler room ru-vid.comUgkxdzUap46p9ViXhKZf5mK_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

It's no really blade less the blades that create the thrust are internal. Anyways I like it. Hopefully it is more affordable than some of Dyson's other products

Interesting, but a lot of air friction involved.

does the impeller produce enough power so that the air flow is not repelled back from the small area?

I love it

You won’t get the x15 airflow benefits for lift generation as that extra airflow is created mostly away from the craft and cannot push upwards on it. But you’ll get a nice breeze!

This wouldn’t work the basic way a drone flys without using flight surfaces is by the counter rotating motors it’s why a helicopter has a tail rotor,that is what stops a helicopter from spinning out of control in the opposite direction of its main blades,it’s also how a helicopter turns right and left by increasing or decreasing the pitch of the tail rotors blades creating more or less thrust. Drones work differently the have counter rotating motors with opposing props that take the place of all the flight surfaces.as the drone goes left,right up,down,forward or backwards it is increasing and decreasing the speed of the individual motors capitalizing on the movement naturally created by the counter rotational forces of each motor ( when a motors shaft spins one way there is an opposite equivalent force in the other direction. So if you used 2 motors that spin in opposite directions you could go up and down but you need either more motors or flight surfaces of some kind to move any other way. With the exception of a centrally located weight that as it’s moved in a directed past the exact center the craft would move in that Sam direction by tilting it,not a very responsive machine and wouldn’t be safe at any kind of speed or turbulence, you might be onto something though if you create adjustable valves to regulate how much air would pass through to each ring and flaps to direct air flow inside of the air channel. That could work. Good first step to a great concept keep it up.

What about yaw control? You need at least 2 motors or propellers spinning in the opposite directions.

How does this drone rudder operate?

or you could use a mesh to solve the problem, like with paramotors?!

Where dose the power come from

Dyson is a particular application of the Coanda Effect.

Is this a dyson (trademark) drone or a Coanda Effect drone?

Nice idea, but it's not practical enough..not efficient enough, thrust power lost..

I was thinking about it for a long time

Build it!

I gotta hear how loud this thing is. I'm looking at that plane they're building with these for propulsion, wondering if it could be used in cities as VTOL cars.

Can improve dramatically the design to maximize efficiency and minimize lots of resistance losses on way the air travels inside the drone!

This reminds me of a flying mower but much, much better, sleeker, more scientifically and technologically advanced, more agile, adaptable, mobile, skilled, fast, powerful, tough, durable and powerful. And of course, quieter, more practical and safer.

Maybe louder the than propellers, less lift?
