- Let this ionic thruster turn some gears, and let my sponsor betterhelp connect you to a therapist who can support you - all from the comfort of your own home. Visit betterhelp.com/plasma or choose PlasmaChannel during signup, and enjoy a special discount on your first month of support.
Perhaps a sequential ionic thrust topology is not the way to go. It makes the most sense, but in reality results in dimishing returns. In this video - I explore the possibility of a peripheral approach to ionic thrust, using triconvergent air, and build it into a thruster which is impact proof.

I've mentioned this before, but you need exponential spacing. You are trying to accelerate a 2.8 column of air with another 2.8 stream input. Because you want external entrainment, you might consider an exponential horn housing. Each 2.8 input would force more air into a smaller space, increasing the speed.
Alternatively, each thruster could be exponentially increased in power, to use the same level of input more efficiently. So like cut the first one in half, raise the last one by double. Without external entrainment, you could change the distance between anode and cathode to accelerate the same stream successively but with increased speed each time. The first one would be closest, and the second one twice as separated, but since the air is already moving, the ions would travel much faster covering the doubled distance in the same time.
I don’t think that will behave as you mentioned. Not sure this system can compress air. But would be worth testing. Likely why he did not see much improvement when doing the spacing.
Would love to see a 15” version of this.
Why not put all thrusters in one sealed tube to get more of a jet effect?
@@JoeyBlogs007 because it won't pull air in from the side to compress it and further increase airflow
@@JoeyBlogs007 or maybe circular thrusters, just kinda hard to build.
Erm Akchually ☝🤓
I really think you need to switch to static thrust measurement as a method of comparing efficiency rather than output velocity alone. For example, you might be seeing the same 2.8 meters per second output on two designs with the same power but one could have way more thrust than the other due to the surface area of the output. You might also have a design with lower velocity that is far more efficient than one with higher. You kinda touched on this with liters of flow but a thrust stand will provide more accurate information.
Grams of static thrust per watt is the gold standard of measured efficiency. You should be making more than 1 gram per watt from what I know about ionic thrusters. 4 grams per watt is the highest I’ve ever heard of from research papers.
^THIS!!!
Great comment, do you think this could be done with just a kitchen scale?
100%
With maybe a little math and providing a point for rotation yes you can use any scale. (given it's accurate) Basically the same as a load cell.
Yeah, he absolutely needs a better way of measuring thrust and efficiency
It seems like all thrusters need to have equal thrust. Otherwise, one is doing most of the work.
I think you should run a design competition and have viewers submit thruster designs and you build and test them.
Love this
great way to farm patents to buy up and sit on.
@@kingmasterlord not really. The moment you share, you can no longer patent the idea.

@@TimothyKNetherlands like they cant make some legally distinct tweak then file a patent that's broad af.
Okay hear me out. If you're not going to do it, I might.
Consider the following:
- A wing profile is revolved radially, such that you end up with a wing profile that's disk shaped.
- The disk is initially stationary with air surrounding the disk.
- Underneath the disk wing, there's 'zero' radial velocity, indicating high pressure.
- Above the wing, there's non-zero radial velocity of air, indicating low pressure.
- The radial velocity of air above the wing is induced by plasma.
- The electrodes are circular rings placed on top of the disk, where the inner ring has a smaller diameter than the outer ring, such that air flow radially from in to out.
- The disk is made using CNC and is supposed to be extremely lightweight, i.e. EPS foam (non-flammable) density of about 30 kg/m3. Preferable thin-walled, perhaps with ribs if there's low stiffness.
- Downward 'Wingtips' around the disk's edge could be used to properly separate the high and low pressures.
- You could use a wing profile that has a very high Cl, i.e. high lift at low speed, since Cl does not rely on airspeed.
- You could subdivide the disk into 4 parts, where each quarter's potential difference can be manipulated, which could help in allowing you to steer.
The idea is to create a solid velocity difference between top and bottom surfaces, to create a strong lift force, where the bottom velocity is essentially zero (stand still). Relying on Bernoulli's principle we can determine the lift force. For a simple rectangular plate with area 'A' being in air with density rho, the lift force Fl = 1/2 * rho * A * (Vtop^2 - Vbot^2).
I've done quick calculations. Considering your and others previous work, I think it's viable starting at ~45 kV. if we can achieve similar airflow speeds, I think we could create the first actual hovering UFO drone that doesn't rely on moving parts.
Some other notes:
- There should be sufficient airflow, such that a 'boundary' layer is formed between the high and low pressure zones. Such that air doesn't leak towards the low pressure zone
- Use foam that is preferably fire-retardant, since the plasma may ignite the foam. EPS should be suitable, XPS possibly not.
- Preferably use foam or another lightweight material for the electrodes. Paint it with graphite spray and use electroplating to make some seriously lightweight electrodes.
- One conclusion I had from watching your videos, is that the air speed doesn't necessarily increase with multiple stages. But it does help in creating a more uniform flow over a larger volume or area. Using multiple electrode rings may create a very uniform flow field above the disk.
Been thinking about this for quite some time, and I am thinking about doing it as a hobby project, but I think this would fit your Channel a lot better and if it works out, it's a world's first! (not considering Aliens did it before we did, lol.)
DAMN BRO COOKED
As an engineering student that’s wants to go into aerospace. This comment is really interesting.
I am not reading all that,but you sound smart and it sounds like a good idea
This is a good situation to explore. You may want to check out my ionic thrust wing I recently invent/built. It’s about 5 videos back. I designed it that way so as to Introduce a permanent velocity difference between top and bottom, creating lift even when the wing is at zero velocity horizontally.
Incorporating that into a UFO shape has potential- though - that air has to come from somewhere. If all the radial ionic segments blast air outward on the top, it means the air must come from a center column in the middle of the top. This does introduce significant drag interaction between air above and top of ufo surface.
@PlasmaChannel, I appreciate your response. I've watched the video, and it's definitely a step in the right direction. If it could be made more lightweight, perhaps it could already achieve flight.
I'm uncertain about the 'refill source' of the air. It could be drawn in from the center top of the disk, or perhaps it's sucked in over the entire top surface. I've been pondering about this. While it seems logical that the majority is drawn in from the center due to the direction of flow, if we consider air molecules being 'pushed' away locally by the plasma, it makes me wonder why the void wouldn't replenish locally either (thus 'refilling' air across the entire surface). But that could indeed be a replenishment due to the flow itself.
Perhaps you could check the inflow velocity of your plasma fan. Is it close to zero, or is there obvious suction? Edit: watching your wing video again, there's obvious suction. So it would make sense it comes from the top center.
Regarding drag, the initial goal is to create a hovering disk, achieving a force balance. Considering the suction from the middle, I'm unsure of the drag's significance. My intuition says it's relatively little compared to the lift generated. However, this largely depends on how air is drawn in, the surface area affected by drag, and the interaction of the moving air molecules with the disk (vector of the molecules). That's why I'm quite eager to see if it would even work experimentally. And if it fails, it'd be a succesful failure, since in the end it's a learning experience.
The primary objective should be achieving a force balance for sustained hovering. The lift force could significantly surpass the weight, especially if lightweight materials like foam are used. If there's sufficient margin, it may also handle the drag, who's order of magnitude is yet unknown.
Exploring its dynamic behavior, it's obvious that rapid acceleration/speeds won't be achievable due to the significant frontal area of the disk.
Please keep it mind; I'm eager to see where the wing design leads! :)
Dude, a second Channel of just you recording the process of you designing and building the prototypes in long form, like an hour or even longer, would be mad and you’d be able to get a video out sooner, less editing needed because it’s a second channel video, no music is really needed, just pure analysis and prototyping. I’d love to see how you do your process and how your brain works.
I often say you can see Adam savages brain work on the outside as he builds things. And I love the rawness of the content.
I fully agree, but it would increase the overall work-load.
That’s a good idea!
@@PlasmaChannelyour 3D modeling skills are off the charts, that's for sure! Your brain never shuts down when you're designing this stuff! Awesome designs... We commoners could never understand the hours you put into this. Thanks for being who you are. 👍
@@PlasmaChannel Nature doesn't do angles. Since most if not all of your ideas and designs are coming from nature (Think about that for a moment), I would suggest you take the shape design of the MKII and the concept of the MKIII and combine the 2. In other words make the MKIII round with 4 sections per circular ring at the same 22 degree inclination.
Better yet, if he records the process for said second channel, that can lighten the recording load for the main channel, albeit increasing the recording and editing load as a whole.
"my work has paralleled MIT's attempt" is not something many people can say. Congratulations man, good work!
I appreciate that, thanks!
@@PlasmaChannelDo you know how awful BetterHelp actually is? You should really read up on their shortcomings as a therapy service. It’s irresponsible to advertise their service.
@@PlasmaChannel 1 trusted 3m/s 3 truster no improvement?
@@PlasmaChannel It might be a good idea to read some of the papers that are open access on the subject, if you haven't already. There are a huge amount of variables, not just lateral spacing of the individual thrusters but also vertical spacing, as well as voltage comparisons, spacing between the anode and cathode, pin vs wire ionization etc. It might be a little too in depth for what you're going for, but if you are working on pushing the technology looking at what other people are working on in the field would be beneficial, it's not just MIT either there are Chinese papers as well.
I love that part of the design change is you've moved from 'how fast can we push air' to the more important question 'how much air can we push'.
Awesome work!
Here are some improvements i suggest:
- measure grams of thrust per watt instead of airspeed
- focus mainly on achieving max thrust at a certain size
- use a single tube design with no holes in the sides of the design to simplify aerodynamics and testing
Robust design like you did was really smart, hope you continue with the ionic thurster. Would love to see this on rc planes or even table fans in the future
"use a single tube design with no holes in the sides of the design to simplify aerodynamics and testing"
The concept he is applying is to pull air in from the sides & push it to the center.
@@guytech7310 Couldn't agree more, he is not concentrating on the thrust, which is the absolute problem with this type of propulsion, messing around with all the other superfluous aspects is kind of lazy, but I know why he's doing that, it's easier than tackling the hard issue and it satisfies the easily impressed viewers out there, so, meh, I wouldn't call any of this really interesting or intriguing. For example if you look at another unrelated channel, ah "Tech. Ingredients" I think it's called, a father and son team who tackle all manner of projects those guys REALLY dig into the science and do respectable work.
Could you imagine the power bill of such a fan compared to a typical 10-20W fan? Sucking down 100W of power just to have a small breeze with chance of electrical shock lol.
@CaedenV haha it’s exhilarating isn’t it? You forgot the best part - a small chance of fire too 😅
@PlasmaChannel iv been trying to explain the basics of my advanced aerospace to you for many many years and though my plasma thruster is very different you miss one major aspect in the technology. You have no pressure chamber around the thruster.... to explain it quick you have a pressure chamber but small scale for yours uses an elastic balloon. The thruster will need a skeleton around it for the deflated balloon to go around. One end of the balloon has a intake valve that can only suck air in from the thruster intake. On the other end you need a pressure valve that will release at a specific calculated pressure needed to launch it... have the thruster work and inflate the balloon building pressure that will fill it to desired pressure the the valve releases and as that happens thrust the thruster full power and it will utilize the pressure thrust combined with the thrusters thrust.. to cool it down so it does not melt the balloon use very cold helium gas dispersed into the plasma field but u think you should be good. Mine uses a metal pressure chamber at high pressures using hot plasma cooled down using very cold helium gas. The balloon method would be good to experiment with before using metal pressure chamber and a thruster that can produce dangerous pressures.
Just a reality check: at 4m/s and a cross-sectional area of about 100cm2 you're putting about 0.3W of power into the air; for a 70W input. Because energy rises as velocity squared the second stage of your first prototype is actually _more_ efficient than the first. To maximize thrust efficiency you actually want to move a large volume of air slowly rather than a small volume fast, something ionic thrusters might be suited to. However, due to the nature of ionic acceleration much of the energy input is going into rotational/vibrational states of the molecules rather than velocity, so it's unlikely ionic thrusters will ever be efficient enough to compete with, say, a propeller. But still fun stuff, thanks for posting.
His structures are basic structures. With more research, better material, and material structures, it will improve. For example, toroidal fins are structure improvements, and it will happen for ionic thrusters, too
@@dennisalbert6115 Iterative refinements like that historically get you improvements of a factor of a few, eventually. If you're starting with a system that is about 0.5% efficient then you're not a factor of a few short of where you need to be in order to be competitive, you're a couple of orders of magnitude behind. At that point you either need a radical change to the entire approach, or just accept that atmospheric ionic thrusters are a very, very cool scientific curiosity but not really a viable form of propulsion.
I haven't checked your arithmetic, but he might well be better off just running resistance wires and running a thermal cycle.
@@BooBaddyBig If turning electrical energy into thrust by moving air is the objective then nothing else comes even close to a brushless DC motor turning a well matched propeller, on more or less any performance metric you choose (except perhaps for low noise). Buying some off the shelf FPV drone motors and marvelling at how good they are wouldn't make for compelling content, though.
Plasma Channel is sticking with atmospheric ionic thrusters because building very cool high voltage physics toys and making well produced videos about them is what he does, and he's very good at it. I just wish he would be more honest that that is what he's doing (as he is in a lot of his other videos), rather than wrapping it up in the "I'm inventing the future of aerospace" schtick.
Great input! I know the pursuit is nearly pointless - ionic thrust will never compete with propellers on efficiency. Then again, I’m not going for efficiency. If I can design a thruster that uses 5 times the power of a propeller system (currently it needs more power than that haha), I’d still consider it a win. Because as battery densities continue to increase, as small scale nuclear becomes a reality, energy requirements for electrical apparatus aren’t going to matter much.
So I’m focusing more on the improvement of thrusters approach, less on the trying to actually beat a propeller approach,
Great input
This series is my medication. Love it. Thanks for showing us this progress!
May you thrust yourself further into excellence. Well done sir, loving your content and brain
I have been designing air ducts recently, and one of the very important things is to not restrict the air flow rapidly. For the best results it's best to stay under 10 degrees of restriction. Keep up the good work!
Funny enough for engine cylinder heads it's about 15 degrees as the limit.

I never regret that I subscribed to your channel. This is a very huge improvement from your previous video about this experiment which is the first video I saw of yours. You don't realize it but I think what you do will innovate this technology to the future and will make a great impact in history.
This guy is good at what he does.. I just hope his Mr Wonderful character wont ruin it.
Maybe you could try a circular design instead of a triangular design. I feel like it might focus the air a little better.
I was going there as well, creating a high speed vortex?
It could be interesting to place a central charged rod so the airflow gets “added” and focused (even directed maybe ?)
High speed vortex why not, but I tried to design this for a water propeller, and you would need Lorentz force = weird magnets placement… Basically you would need a magnetic field that goes to the center (hence the rod), and a way to attract it to a focused point in the back + a “venturi” style system could be interesting as the air would be pulled in the vortex… I would try this if i had high voltages and strong magnets…
Agree and a better power to weight ratio as the cylinder has a natural strength advantage, so you can make it thinner
I was thinking the same ! Like anode and cathode be rings from bigger to smaller with air guides within to guide airflow

Super cool! Can't wait to see and talk at open sauce! I need to finish my videos about my projects. I also can't believe it's been a full year since your last version of the engine. Super super cool technology and I love the progress
1) They need to still be circular. They can be segmented...1/3 or 1/4 circle for each thruster, but a round interior will create smoother airflow and offer larger internal area for objects to fit through without compromising volume.
2) You'll need to find a way to more smoothly merge the flows so that they compound one another. As it is, currently, they're slamming into each other and losing energy. They're not blending together to improve flow, and they're losing velocity in the process. My recommendation would be to find a way to offset the thrusters at an angle, laterally. Instead of merely tilting them so their exhaust is pointed inward, also tilt them so that flow is off-centered, to create a vortex. Then they shouldn't be slamming into one another, but more like merging on a highway.

this design is also very good for stacking it ! or making a wide straight surface.. looks awesome!!
Been waiting. Nicely delievered.
So in all honesty if you have a taper after all stages are done with a reduction of 15-30% and some splines/fins to reduce turbulence towards the exit and get some better linear flow you can get a massive boost to your velocity.
Love the videos best of luck.
You could take inspiration from axial compressors, and have your cross-section slowly reduce for each stage to improve and achieve a set pressure ratio by the end. One reason why in your case more stages doesn't seem to help is that all stages are identical. However, downflow stages will need more power and a different geometry since they are fighting a higher pressure. Then, your high pressure flow could go through a converging nozzle to accelerate even further (or just add more and more smaller ionic stages along the way, it might work as well).
It looks futuristic! :)
This is my favourite project on CZcams
Hi Jay. Did you measure the thrust force in newtons or grams. To check the thrust to weight ratio?
He's probably doing that behind the scenes but I can't imagine him really getting on stage just yet to show those numbers, maybe when he gets further ahead he'll start seriously giving us TWR numbers
C'mon, the flames weren't enough to convince you that this tech could rival propellers? Only engineers are concerned with numbers and established methods of testing. This isn't for you. It's pretend. For views. For people who don't know better

I just have to say I have been a Bill Oddman fan for years now and the fact that the chaotic menace that he is has brought people together for OS is kinda amazing. He’s like the general no one can predict.
I love seeing Excelon products in your videos. 🥰
I share my knowledge: NIM engine. (Negative-Impulsive-Magnetic) Engine. (Because you build things, so why not help a bit)
Nice idea with the waves but you didnt use it yet in your thruster. You recognized some air is sucked into the thruster, although it thrust air out?
What is missing is the consideration of how the air consist and what actually move the air... electrons. Electron speed is determined by the voltage.
If multiple thrusters are in row, it accelerats the air with the voltage-plasma but not beyond the voltage.
Also the distance of the accelerating parts could be 1 factor at your build, also try to get lower ampere with same thrust results.
In SHORT: Air volume calculation, air consistance calculation, thrust calculation with air, thrust efficiency by testing the best volt to ampere ratio, Thrust Frequency.
Air(A): volume x consistance, Thrustfactor(Tf): volt x ampere, ThrustOutput(TO): Tf x A x TF (Thrust-Frequency)
Think of the electrons AS if its waterdrops. Always make the plasma visible once to see where its flowing (helps alot).
Also a magnetic field guides the electrons, because these are negative charged.
yeah, good stuff. Regarding the electrodes potential and air flow, I think it would be worthwhile looking into sequential electrodes at progressively higher potentials, and possibly a pulsed arrangement...
All sounds nice an all but electrons are lost to IONs that provide the thrust so straight off the bat you haven't a clue, lets see " thrust calculation with air, thrust efficiency by testing the best volt to ampere ratio, Thrust Frequency." This is bollocks its nonsense Volts * amps is power in watts and what the hell has that to do with thrust frequency. You got some tart your trying to impress ?
@@ashleyobrien4937 Realy you as well ? FFS
@@andymouse awww, they was on the right track at first, that air has to move and it takes energy to do so...
got carried away with silly things rather than thinking about where the actual action/reaction force is, to MOVE air requires an action with equal and opposite reaction... where is the reaction?
the only thing you have to "push" against is the charged molecules. the inertia of the air molecule, its mass, its refusal to change path, opposing the electrostatic forces. what proportion of air flow is due to charged molecules being repelled/attracted to electrodes, as opposed to neutral molecules being impacted, absorbing kinetic energy, and slowing the charged particles down?
in a way they was right with the voltsxamps. how many watts goes into just making corona, leakage currents, how much is put into actual force over time on the frame, the electrodes?
how much thrust does it make, how efficiently?
air flow is not the same as thrust...
entraining air doesnt create thrust. air that is dragged along by air you pushed on is nothing but drag. ie, dyson fans dont make thrust by accelerating air through the ring, the only thrust is at the nozzles, the air they sucked in and compressed and release at high speed.
but once that air is moving it can perform work if redirected ;)
you have to push on air. or get it to push on something... other than more air!
@@paradiselost9946 Yes I agree with you, and your making more sense but I must correct you It was me that pointed out that W =P x I not them and an increase in watts is going to increase thing to the point where they can catch fire but why did the say 'Thrust frequency ? gobbledy gook ! not a clue

If you are referring to the X3, that is designed to operate in the vacuum of space (hall thruster), which is a *completely* different set of operating and design principles (main acceleration via magnets, inert gas "fuel" simply injected via nozzles, no entrainment of surrounding air mass, no atmosphere to fight against particle acceleration, etc. etc.).

I have an idea !!! Why don’t you make a hybrid ionic thruster ! One with metallic rotating blades and the blades are positively charged and also being driven by a motor and there are bunch of grounded wires at the end
Airflow would be fan+ ionic thruster
I’m not sure but…The air could try to go sideways to follow the blades, slowing them down and blocking input… interesting though… Or it could make an air vortex since you put the grid. (Rotating grid ???)
@@romanbengaldrole4061 🤔 interesting idea , but grids at higher airspeeds kinda became bottlenecks , but ionic thrusters don’t have a very powerful thrust , it would be very interesting to see it in an experiment
@@VandalIO There is a solution : Place a central charged rod, with a higher charge at the end(outputs of generator), and use the Lorentz force to create rotation.
@@romanbengaldrole4061 that’s an interesting one , or we can use a vortex tube like design
Then you need additional airflow from the side, unless you make some of it converge from the side, which is complex, but should be extremely efficient of optimized (I’m not a specialist though)
the problem with Ionic thrusters is that the situations where they are better than a simple propeller are very rare.
I would also love to see a thrust per watt stat.
Would be cool to have an ionic propeller. That way the propeller moves due to ionic motion, and the air moves because of the propeller.
@@FemaleRoleModel What about putting the "thruster" concept on the leading edge of the propeller just for directing the air smoothly over its surface and especially around the tips of the prop?
@@alleycatsphinx I like that a lot.
i have been fascinated by this project. keep nerding ;)
Awesome, please continue!)
My “physics nerd common sense” is telling me that a circular shape might help with a more uniform flow, as the three streams coming from the triangles are probably converging in a pretty awkward way. Also some way of directing airflow from each peripheral thruster(like a duct or something) into a smaller output area in the center would likely help reduce turbulence and increase the velocity of the airflow (assuming you are building this for velocity and not displacement ). I am a high school senior so take this with a grain of salt lmao
Spiral shape! Bending metal is easy.
in this case, the velocity of the airflow means nothing...
air flow is not thrust. the thrust is only due to the mass that is worked upon, accelerated.
and the only mass that is worked upon is the charged air molecules. their mass being repelled and attracted to the electrodes, being moved.
the issue is that a lot of the air flow is produced not by being charged and repelled, but by getting in the way of the charged molecules that ARE being worked upon...
you perform no work on moving that air. that work is due to the air you did perform work upon being SLOWED DOWN.
the only way to get that air to perform work is to make it change direction, it performs work against something... which is what you see when you "blow stuff around"... air slow down, stuff get accelerated away.
on a turntable, against a dyno, a load... i reckon it has virtually no thrust. all blow, no show :)
but if it had a blade mounted behind it, angled appropriately, and spun "backwards" due to redirecting the total flow...
and yeah, cones, ducts, circles, curved surfaces, always better... electrically and aerodynamically...

@@Danman350 lol. who gives a damn?
Idea: what if each stage of thruster was closer to the central stream? The pass-through benefit would be sacrificed somewhat, but it may provide significant improvements. And what if each stage had a different angular placement relative to the thruster's longitudinal axis? So the airflow would get deflected at almost 45 degrees at the first stage, narrowing down to 10 or 12 degrees at the end? Or maybe in reverse? And what if the angle and spacing was variable while in operation? You could find the most optimal placement and angle at every airspeed and automate them somehow so the thruster automatically scales thrust with speed?
Like others have said, I think this design would also greatly benefit from exponential spacing.
As a product designer, my advice is to research what was already done in the "moving air business". Aka fans, vacuum cleaners, blowers, coolers... There are a vast amount of research in aerodynamics applied to those products. Just look what Dyson does by shaping the air flow and utilizing centrifugal forces. They are great source of information.
It's great to see your improvement!
Congratulations!
when you stack them in series, the electric fields could be interfering with one another.
just as the air can be pushed forward, if you put another thruster in front it could add to an opposing force.
it would insanely cool to see a lightweight drone that can hover using these.
A 30kv power supply and lightweight don't go together very well
I kind of forgot about the power supply. Thank you for pointing that out.@@younscrafter7372
@@younscrafter7372 what about remote power - is there a way to beam electricity at a wire to charge it up?
Amazing! You're part way to a turbine engine with no moving parts. It's possible there is turbulence happening between each stage as you're compressing air and then running the next stage at the same size. It might make sense to reduce and move the 2nd stage to the size of the covergance point of the first stage. Not sure of the 3 stage, maybe the same or go larger than the first stage, like and afterburner, with a case the diameter of the largest stage, assuming it ultimately needs to be fit as such in a plane.
Also, redesigning it circular as opposed to triangular will reduce internal turbulance, adding a slight twist to the blades to create a vortex should also stabilize airflow.
Just spit balling, you're doing great stuff.❤
This is an awesome project. It would be cool to see a circular (ring-shaped) wing thruster. You'd get the same hollow center you're looking for while also using the support structure to provide lift
Aero engineer here:
See 3:12
E=0.5mc^2 so your % increases are being underestimated.
Energy @ 2.1 ~ m*2.1^2 = m*4.41
Energy @ 3.2 ~ m*3.2^2 = m*10.24
So delta energy ~10.24-4.41=5.83.
This indicates the second stage is actually more efficient than the first. AND considering you are entraining more air, the mass is probably higher so this is already underestimated.
Hope this helps!
I think you mean E=0.5 m v^2 and if so, I agree.
@@WiggyBI hope not! I've been using my version for years 😖😂
Yup, efficiency is about energy conversion - in this case to kinetic energy change: 0.5*m*(v_{2}^2-v_{1}^2).
If the relationship in velocity continued in the linear way that seems to have been expected, conservation of energy would have been broken :)
@@Raphvsmith I dropped out engineering. But your formula is the one by Einstein for general relativity, and his is the formula for kinetic energy. but i don't think we know the volume or weight of air here so i don't see how any of these really help, maybe to estimate? what do you mean energy @ 2.1? energy like joule? how do you know did he say the wattage? if so then we would still need to know the efficiency of the device and subtract that no?
Sorry to nitpick here and my idea may not be entirely correct either, but the c in this formula is light speed and a constant (you can’t plug velocity in there!)
The (kinetic) energy formula that applies here is E(kinetic)=1/2*m*v^2 since we are well in the realm of Newtonian physics. Your point still remains with this formula!!
Besides, I believe thrust and specific impulse are more important since this is a thruster. Specific impulse kinda is the efficiency of the engine and correlated to exhaust speed. The added stages increased that with diminishing returns.
The actual thrust was sadly never measured here. Measuring thrust with maybe a scale or so would have been interesting, because thrust to weight is the limiting factor for using this on a plane I think.
Your comment got me thinking so I had to reply:)

Love these ion thruster videos, looking forward to seeing you put them on a boat!
Btw, you've probably already seen this, but you may wanna do some more research on your sponsors beforehand.
You really made the Tony stark New-Element Arc reactor of ionic thrusters.
You could change to a design similar to a Dyson Fan, with a small inlet at the front surface. Curved surface and using an aerofoil design to reduce pressure further back in the ring design would create a venturi effect allowing the air to move faster, you can then recombine the two streams of air both now traveling faster together, increasing the pressure again, as they combine with the outside air you should gain a larger net air throughput. Ensuring the outer and inner surfaces are smooth and dont cause too much air turbulance.
You could also create multiple voltage points.
Entrance 2xV, V, GND
Any air that entered without being energised can then be energised at intermediary steps. This would keep the voltage differentail in one direction, otherwise you could end up with a second stage causing a counter effect.
if you think about it, having a hollow center has the additional advantage of using bernoulli's principle. Since there's moving air at the tail end of the thruster, surely there's a low pressure cavity in the center front section which is also contributing. Though I would think the individual thruster unit (one side of one triangle) should be a little shorter to maximize that effect.

Awesome work, thank you very much!
Some Physics here is helpful.
You want to optimize for the most thrust for the least power.
You get thrust by accelerating air backwards. The momentum of the air moving backwards is m*v; the kinetic energy of the air moving backwards is 1/2mv^2. You want the most momentum for the least kinetic energy.
Maximizing mv / (1/2 mv^2) you get 2/v. In other words, your efficiency drops the faster you move the air.
However, there's also a few other considerations here!
For one, you seldom will use a thruster like this while truly stationary. And if you're moving forward at 10km/h and your thruster moves air back at 5km/h... you aren't actually making any thrust.
When you work out the optimum, it works out to "you want to move air back at 2x the velocity you are moving forward". This is why props work well at low speeds, then turboprops, then high-bypass turbofans, then low-bypass turbofans, then classic jets, then ramjets, then scramjets, then eventually rockets as you increase speed. It's "all" about the exhaust velocity. (Well, not entirely. But largely.)
However, this then gets into the second consideration: if you want to move air back slowly, you need to move a _lot_ of air slowly. And you can only fit so much through a given, say, 10x4cm hole. Especially if the air is moving slowly.
I suspect if you wanted to maximize thrust at low speeds you could do better by optimizing to improve the amount of entrainment air. Look at e.g. bladeless fans for inspiration.
Wow, such an amazing video! I love seeing new ideas. Nothing like trial and error to come up with a huge breakthrough.
I'm not smart at all, but stupid ideas sometimes make great new discoveries.
But just thinking out loud, you mentioned that putting them in parallel will boost the speed so much. What if instead of doing them all the same size, you do all three different sizes? You can make the first one the smallest, then make the next one about 50% bigger, and the last one 100% bigger than the first.
Great content learned alot loved the video besides the prederhelp ad
"Science is not a perfect science" -Jay Bowles
Seriously enjoy watching the evolution of the BSI and I very much appreciate you sharing the entirety of your iterative process including the setbacks. Things don't always go the way we hope but thats what drives us to find new solutions and get to better outcomes. Keep up the great work!
Love the video! I think about the design differently. The first stage has to be the backbone of the structure of the cone. Think about how a black hole works and everything goes to one fixed point. you have to stretch the fixed point from the first stage past the third stage. to where stage ones maximum performance is passed the third stage.
Stage 2 has to be some type of feeder system for stage 1 and stage 3. I haven't figured that out yet. After all, there's going to be a shell around everything. Nothing can be exposed to the elements.
Stage 3 needs to be the torque adding the horsepower from stage 1.
Maybe some vector control as well.
I really enjoyed the video
A really important thing is thrust and drag coefficient. You could measure and add them to the next video. That would be useful in comparing different designs.
Love seeing the progress on this man! I think it would be interesting to try using a tapered sealed tube instead of a triangle. Then angle the thrusters in such a way where the incoming thrust creates a vortex inside the tube to draw in more air from the inlet.
Pretty much create a jet engine without any blades with thrust vectored air instead
Source am mechanical engineer
Way to go man! i have a inkling that you will reach 1 Million subs by the end of this year🥳🥳
I think your problem is the line of convergence-you mistakenly assume that an efficient angle of output from one will not cause interference when stacked with another. Try a version that allows you to adjust the angles of each set of 3 "blades", not just the gaps between each set of 3. AND-there will be less air interference if the entire thing is housed in some sort of casing. You can always add slits to this housing to allow strategic air input that is efficient-and cut out airflows that are not!
Glad to see you have some new ideas. I never saw it this way neither live or in my mind. I hope you will patent your results so, even if you will not reach your primary goals, you'd been able to get some profit on side-uses. Room fans, may be, or air cleaners.
*Think about compression. Like in jet engines. May be you need some diameter gradient for individual thrusters. Can't see if it should be positive or negative -- experimenting needed.
Few design changes I would make
1.) less steep angle so less loss of energy when the air streams collide
2.) the sequential thrusters have diminishing returns, but are more efficient. Using multiple sets of 2 sequential thrusters converging into one stream would give a more efficient and powerful flow I believe.
3.) use a circular thruster and angle the outputs of each set of thrusters in a way to produce a vortex inside the body of the thruster.
Just some ideas.
The first 2 yeah, but making a vortex would waste kinetic energy spinning instead of going directly backwards
@@virutech32 yeah honestly no idea if it could help by pulling in more air with Bernoullis principle or if it would waste energy. it might be good for atomizing fuel if you were to throw the electric only part out the window though haha.
@@gavinhicks7621 It would pull more air by not spinning since that would push air out of the inlets. chemical-ion hybrid would be interesting. probably as an after-burner since flames could compromise the resistance of the air-gaps.
By colliding the streams of air in a column you are inducing massive turbulence and a high pressure field behind the engine. that might sound good, but it basically makes the engine need a stronger internal compression to overcome it. I suggest to either increase the size of engine intake the further to the front, or to make them exhaust parallel to each other. In other words, either brute force a large intake into a small output and compress it down with each stage, or make it all flow parallel and avoid compression and go for airspeed. To illustrate with water, laminar flow moves more water compared to chaotic flow at the same pressure and pipe diameter, but if you want to increase the pressure, its easier to just force it down the tube in chaotic flow by increasing the pressure.
I appreciate the honesty of showing your new design is not necessarily better as a trhuster, even if it has some of the other advantages you mentioned. I think you are focusing on the wrong part of this problem though. Changing the shape of the thurster might help make the use of power more efficient but the limiting factors to the flow rate, for constant mass, are going to be the voltage difference across the path along which each ion is accelerating and the charge of the ions themselves. You can't do much about the ions if you are using atmospheric air, so you're only left with addressing the electric acceleration problem. You could also use compression and heat, but it would no longer be a purely ionic engine.
I love these videos!
You make it actually understandable
You have to trade velocity for thrust, just because the velocity is high doesn’t mean you’re creating more thrust, both are good for different things. It may help if you look at optimising the accelerated fluid coming off the trailing edge of the thruster especially if you’re going to use converging flow. Inducing some vortexes to energise the flow and control the turbulence of the air streams going back together
Love your content, and I’am thrilled for the next step. Maybe additional thrusters don’t multiply the effect because they all have the same specifications. Is like you put 3 Dyson hairdryer (or fans) behind each other. They just move the same amount of air as one. If you want multiplying the effect maybe is better with different sizes and different distances to each other to direct the air like a lens the sunlight.
See about 70% of the words you used i did in fact not understand. But i love seeing stuff like this and thinking about how it can be incorporated into different stuff although i have no clue how incorporating this intio something would work.
what would happen if you hollowed out a large rc planes wings and put one straight section of this in each trailing end of the wings with the aileron motor rotating the propulsion system up or down to simulate pitch and yaw, the air intake could be pulled from a makeshift hollow bomb bay in the belly of the rc plane with a mesh in the bay to act as a intake filter. Which as long as you dont crash the propulsion system should remain relatively safe. Sounds like a really good project.
The final stage that’s outputting the fastest velocity is fed by slower earlier stages, similar to a gas turbine compressor. So the earlier stages need to gather more air to not restrict the final stage(make them bigger like a jet with a large fan disc that graduates down to the smallest row of blades)
With trial and error, figure what end velocity is then figure cfm’s, and expand back to the first stage and you’ll get the flare rate needed and then put the stages together in a sealed path not letting outside air in. I think you’ll figure out, at that point, how to bias the earlier gathering stages to help boost whatever is possible for the final stage, or stages.(it might look like a trombone horn, but hey?)
This is the same mechanics as stacking three same sized ducted fans in a row and getting diminishing returns from that.
Think, how do fans make jet propulsion, and apply it to your ionic stages, but seal off the outside air, it’s not helping.
Dude I love your channel!
I appreciate that! Are you a maker as well?
Use tubes to converge the flow, then use a nozzle on the big tube to accelerate even more
A few people are mentioning measuring the thrust. Meaning measure how many pounds/grams/kilograms/newtons are pushing. Dividing by watts gives you efficiency. Or dividing by weight of motor is interesting as well. Velocity is of course important as if it is only 3m/sec and doesn't improve much in a headwind then your airplane can't go faster than 3m/sec. But I recommend concentrating on static thrust. grams of thrust per watt. You can use a kitchen scale or, better, get a load cell and build a test stand. Calibrate the load cell with a kitchen scale, suitcase scale, or similar.
My grandfather used to build model airplanes as a hobby.
I used to love watching when he'd heat treat the laminate that covered the wings.
Perhaps you could achieve a significant weight reduction by replacing several of the plastic "wall" segments, with some sort of laminate covered exoskeleton.
I think having the stages that close isn't allowing the streams from each stage to converge before hitting the turbulence from the next stages. May want to try spacing them farther apart, but with shielding to prevent more air coming in, but have SOME air input to prevent a low pressure / vacuum area formation between stages. That would allow each stage to fully converge before being added to or even wrapped with the next stage column. As I was typing this, I also thought that, if you alter the angles of each stage, you may get coaxial flow where the stages can "wrap" the column of the previous and allow for, maybe not more velocity, but more total mass flow, resulting in more overall power output. You can't totally think of the velocity alone, but how much air is being moved at said velocity. 2m/s for 3 L/s is going to be more power than 4m/s for 1L/s. You simply have more kinetic energy being output. Air is approx 1.2g/L, so for the above you would have 60mN vs vs 47mN, respectively.
