Next-Gen Ionic Plasma Thruster Inspired By Nature (BTC Mark 3)

[@BillDeWitt]

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.

[@TheObserver567]

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.

Erm Akchually ☝🤓

[@MarcStollmeyer]

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.

[@HYEpower]

​@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.

[@peterdoyle8571]

Consider the Hal effect thruster: 1) Add a strong electromagnet at outlet of the thruster to generate an electron vortex. 2) Place mini electron guns around the outer rim of the thruster outlet to generate electrons for a virtual cathode 3) Place a large anode (looking like a v-spike engine) within the housing of your thruster 4) At the front end of your thruster, place the necessary support structures for the anode + wiring, be sure to leave most of the front end opened for intake 5) Use your original thruster to provide slightly ionized air to the thrust chamber

[@davidharley7753]

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.

[@dennisalbert6115]

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

[@anthony_horton]

@@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.

[@BooBaddyBig]

I haven't checked your arithmetic, but he might well be better off just running resistance wires and running a thermal cycle.

[@anthony_horton]

@@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.

[@PlasmaChannel]

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

[@TimothyKNetherlands]

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.)

[@FIashOOT]

I am not reading all that,but you sound smart and it sounds like a good idea

[@PlasmaChannel]

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.

[@TimothyKNetherlands]

@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! :)

As a British child of the 80s, my schooling and life even now (I work for American firms a lot and also with electronics), which is a blend or should i say, confusing mixture of metric and imperial. Britain STILL measures weights in metric measurements in metres, CM, MM, inches, feet, and miles. Road speed, distances, and consumption are ALL miles and gallons (UK). PCBs are fun as "mil" in Europe/metric is an abbreviation of Millimetre. "Thou" is 1/1000 of an inch. In American Imperial, "mil" is 1/1000 of an inch. So when I lived in San Jose I had to choose my words very carefully. We will never lose the mixture of both until ALL nations switch and industry follows....which I doubt will ever happen.

Sorry Jay in 2018 MIT did NOT build the "world's first ionic thrust airplane," or "aircraft" as they stated in their paper. Although it was the first traditionally shaped such vehicle, there is an earlier more efficient ion propelled aircraft that does carry its power supply onboard. There are approximately 45 videos of the earlier series of ion propelled aircrafts on my KZbin channel that create much more thrust per watt and were patented for lifting their onboard power supplies entirely with ion propulsion! All of these crafts are capable of self-contained VTOL as well as horizontal flight. They are extraordinarily well verified and documented to fly carrying their own onboard ion propulsion systems. They were designed in a particular way because it was challenging to get them to lift their own power supplies with ion propulsion. I think creating ion thrusters that are capable of lifting themselves vertically, as well as horizontally, have much more potential because this really is a form of ion rocket and will be capable of very high ISPs when operated in a vacuum, (in that case with added propellant). The ion thrusters I built have wing shaped collectors and so can produce aerodynamic lift as well when used in atmosphere without added propellant. There are already solar cells available that will enable these Ion Propelled Vehicles to fly all day long in the near future.

@@extraziadeh NASA has been making heavy solar ion propelled spacecraft for years, such as the Dawn spacecraft etc. To power a terrestrial or air breathing ion thruster with a greater than 1 to 1 thrust ratio and with solar power, you can use my designs and utilize "Perovskite" solar cell films. There are lightweight aircrafts that were flown with these types of cells, but the cells were custom made, challenging to get ahold of, have a short lifetime, and are expensive. Perovskite solar film can be much more powerful by weight than the lithium polymer batteries I have been using. The commercial versions that I know of are pre-encapsulated aren't light enough.

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.❤

[@DoremiFasolatido1979]

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.

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.

10:15 I could be wrong, but it seems to me that this design would create a great deal of internal turbulence and restrict the flow. Suggestions: First - Reduce electrode segment lengths and add more of them to change from a triangular shape to an octagonal shape (closer to a circle). Second - Angle them both inward toward the central axis (like you are) and to create circulation around the central axis (closer to your ionic tornado) I believe this should reduce the clashing of air columns (10:19) that create turbulence and improve the airflow to increase the output pressure.

[@simontanguay3619]

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).

[@gavinhicks7621]

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.

[@virutech32]

[@bmssenjoyer]

the angularity is inducing turbulence and therefore drag in your air column. consider modifying the thrusters into each comprising 120 degrees of a circle, and directing the thruster output offset from parallel to the axis laterally by a small degree. by inducing a vortex in the air column, you reduce turbulence just as bleed air louvres do in an afterburning turbofan. also, you might consider modulating the diameter of the exit with exhaust vanes, or some facsimile thereof. thus, you can increase exit velo significantly

You were getting absolutely correct results with Mk 2.

Would you mind trying out a christmas tree configuration in order to get a proper convergence? Smallest accelerator at the beginning, "nested" in the second stage, and so on, and so forth , with each stage widening. Another thing to try would be a shared electrode design, where AC drive would power 3 or more electrodes of identical dedign with rounded leading edge and jagged trailing edge, fully utilizing both half waves. Just my 2 cents. Awesome work 😊

[@Linqua2112]

The wing design focuses on convergence of the air to the rear of the thruster but from the front you have air coming in and being deflected divergently. At high flight speeds air entering the thruster will strain the corners and the wings will want to fly apart from the center

[@aykyi2668]

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.

[@ashleyobrien4937]

[@Psrj-ad]

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.

[@TheLoneWolfling]

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.

Put a thin plastic cowl over the top of the system. That will channel/funnel air through the system, rather than pulling it over top of and also through the system. Less turbulence, more straight-line air flow. The air being pulled down and through the system is reducing lift and also slowing the straight-line flow over the top of the airfoil. You may want to have the thrusters between two airfoils rather than just sitting on top of one.

[@mattw_929]

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

[@float32]

Spiral shape! Bending metal is easy.

[@paradiselost9946]

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...

Bro, why BetterHelp

[@badabing7820]

Use 4 blades, blow the air into a closed room/space, with one small tube at the end. Each blade, depending on its energy, transports a certain amount of air from A to B. Together they all create a certain pressure. Through a short, small opening, this pressure will lead to a higher exit velocity because the 4 blades push air into the room 4 times. You can't combine the other ones, cause the flowing speed is everytime the same. 2,8 is still 2,8, just two times. You need a higher speed, to speed something up. So use space, to combine the pressure, the more air in a second, the higher the pressure and the higher the pressure, the more speed you get out.

You definitely need to increase the power at each stage. Maybe even increase spacing at each stage. Right now you are just seeing how much air it can push, but in real world applications it will be pushing air to move itself.

Each stage would need to be progressively smaller but with larger scoops and more power applied to each stage with the entire thing covered

[@BartJBols]

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.

[@kameronclark7760]

[@NERvshrd]

I'd suggest putting the fog tray in front of the device and film the intake and internal interactions at high speed. that will give a better view on the interactions and how the air actually moves, as it seems like there's far less efficiency gain per-thruster with this design. Since pressurization reduces the subjective efficiency of each stage, Bill's suggestion to use exponential power scaling for each thruster might work. It also seems as though the third thruster really isn't adding much considering the extra weight it adds. Would more power (and more robust connectors if needed) fed to only two thrusters ultimately be more economical? what happens if you cover the front/top of the 1st thruster? Does that alter the airflow?

[@stevescuba1978]

Your design at 3:15 has me thinking of sequential stages of compression in jet turbine engines. Each stage "packs" more air into the next. I wonder if there is a way to incorporate a larger first section, filled by sequentially smaller diameter but longer stages of ionic thrust. Instead of trying to make more velocity with thrust, try to ingest a larger volume of air into the system while increasing velocity in stages. A simple circuit would allow you to put variable resistors to each stage and dial in the proper voltage for each. Just $.02 from a newb Edit to add: just because you have all these technologies available, don't overlook the old geniuses and their slide rules. Look at the rc plane and kite building hobbies for light, strong designs and materials. A shrinkwrap wingover a skeleton frame is way lighter and plenty strong. To couple with my suggestion about sequential stages of thrust acceleration, look into the horns from old Hitachi motorcycle carburators. Their design reduces the turbulence of incoming airflow, something I think your thrust assembly could make dramatic use of.

[@aubergine10]

If you pour water down a pipe, it tends to clog beyond a certain point. Unless you put a spring coil inside the pipe to make it vortex. Greatly increases water flow; a trick some aquaponics setups use. Same effect likely applies to air. Also, with cylindrical shape, you'd be able to have some fun with Venturi effects.

[@Gigahydra]

I have a few ideas for possible improvements? 1. If you used a design similar to this, could you use a high powered fan to accelerate the ionic thrust? 2. Could you use a jet engine's rotatey things to direct the flow better? Sorry if I've missed why these wouldn't work, but I love the channel! 😍

[@fusion-star]

Hi, thanks for the cool video. This thruster has a cool idea behind it, but if you look at the veins in a leaf, you will see that there is some distance between them. I think you will achieve much better air flow with 70 to 100mm between each thruster section.

[@ericberger394]

[@im_ricebowl]

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.

[@T-Nee-Weighner]

Physically, it makes sense that you wouldn't see an increased velocity. Your thrusters are angled to create a central column, but not to pass air through the following thrusters. That results in more air being moved, as you saw, but no increase in velocity. Pushing the thrusters closer together actually seems like it would interfere with the air being moved, as it would now just crash into the wall of the thruster ahead of it. I wonder about combining the 2 blueprints to pull air from the sides and angle it down into a central thruster with a greater separation between positive and negative. All the volume of your auxilary thrusters, with the speed of a central thruster.

[@TheKillerHeadAche]

My initial thoughts say you need to minimize incoming feed air except for the initial intake areas consolidating any types of drag or unfocused fueling air to your thrust column. If you optimize the convergence area of all three stages around that 10cm length you may be able to optimize the thrust increase. Somewhere after the 10cm mark should be the First Stage's terminal velocity. If you can identify this area and stack the following stages to influence directly to this area the PTV(point of terminal velocity) should amplify, PTV locations for stage 2 and 3 convergence areas may need to adjust due application of thrust and terminal velocity area.

[@neiltutbury35]

I'm thinking along the same lines as BillDe Witt. Using the same shape as a wing with the skin attached, so it is enclosed, including the sides, make the leading edge large, tapering back to the trailing edge. You will have to play around with different size ratios of the entry and exit to find optimal thrust.

For Ionic Thrust Boat, you could direct the air stream to the water to have a push from the surface being hit by the air stream. And also improve shape... Imagine a spiral double or triple helix thruster maybe with air guides to make the thrust coming out of the tip of the cone shape. As a nosel.

[@toobin8r]

I could imagine changing the angle of the inputs might help: after the air’s pulled through the first set of inputs, it’s moving more horizontal than at the 22° angle, but as that air passes the second thruster frame, you’re reintroducing air at that 22° angle, so there might be a spot that’s got some backdraft, kinda like how there’s sometimes spots on a river where the water’s flowing back upstream. Maybe doing something like having the first set of inputs angled like normal, the second set angled somewhere between 17.5 and 15°, and the third set closer to 12.5°, something like that, might help.

[@michaelamorello3348]

Been a pleasure following the iterations of these thrusters!

[@RyanF470]

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.

[@greenmario3011]

It would reduce the speed of the airflow but I imagine you could increase the thrust and efficiency by having more modules in a wider, more circular ring. Diluting the energy across a larger central volume of air gives a larger change in momentum for the same power input, and the three flat jets intersecting at sharp angles could increase the level of turbulence (and losses) inside the engine.

[@privateerburrows]

The "diminishing returns" in adding stages may not be diminishing returns. I'm thinking, kinetic energy is m * v-squared. So, the 50% speed increment of the second stage represents 2.25 times the energy; and so on. If I'm right, the second stage transfers more power than the first. The problem is that what benefits propulsion is momentum, rather than kinetic energy of the exhaust.

[@Lotusfourteen14]

It might be a good idea to be able to precisely measure the static pressure developed as well as the flow rate. In essence your would be developing a thruster curve ( similar to a fan curve). With this tool you you might be able to find the optimal configuration for your thruster designs. You would need to develop a laminar flow element to measure differential pressure and have a fan to pull air through the flow bench at various static pressures. You could plot a curve by measuring static and differential pressure on a graph. Omega and Meriam might be good resources for flow bench design. I would think that thrust is more than just cubic feet/min.

[@SilvaFox]

You are converging the air in the center evenly. I feel like the very first set is creating turbulence with the non moving air already in the center at the front hindering your total work flow. I would think you would get better total air movement by off setting each triangle corner so they create a vortex in the center. Like tipping a water bottle upside down. The water just glugs out as air tries to replace the water. But If you whip the bottle in a circle the tornado formed, allows the water to pour out quick. So take one triangle group. Rather than have each piece end to end, at each end meeting point move one side backwards and the other side forwards like less than a centimeter. Then do the same thing for the other two corners. Then follow through with doing the same for the other three corners of the other two triangles each. Would that work to create a vortex of air in the center minimizing any turbulence created? Or are the angles created by having a triangular frame two shallow?

A great improvement on previous models, you mentioned influences of nature ?.. A powerful force of nature is the vortex.. what happens if you rotate each section by say 30 degrees, maybe a nozzle or tail pipe.. keep up the great work..

Your works are astonishing. I feel a great comfort watching them proceed. Also it is very interesting how all evolves. These are remarkable. Nevertheless some of your Commentators propose improvements, for example exponential spacing. So i am also very curious how you do propose to deal with turbulent air drag or mentioned venturi effect or an intake and an exhaust stall or other aerodynamic effects etc. in this electrostatic compressor. I see there is a racing car chassi constructor challange. Hehe. There could have been a method of sequential charging of each condensator with a certain frequency to overcome turbulent drag created by pumping this gas through the compressors interior. Also it could take many years before any closing conclusions appear. Though, it all does look very future proof. All the best wishes.😀

Hello, I work with plasma/corona and fluid modeling regularly. I love the inspiration from nature, but seems like the convergence idea isn't a great application for fluids, unless you converge them at extremely small angles. The larger the angle of attack, the more turbulence and flow "cancelation" you will get, which basically means you just want to run them parallel to each other ( 0°). Also, you need to think about how the air gets accelerated by ion flow between the electrodes. They are accelerated toward a surface, which means you are moving most the air by entrainment due to the ion flow. Optimizing the electrode geometry to reduce drag off the faces and increase entrainment may give you a big boost. Like others in the comments have said, you shouldn't Use velocity as a metric unless you want to produce fast moving air. If you want a thruster, you want thrust! Measure the thrust with a force gauge. Thanks for the good content and high production value.---- Oh also, you should be carful how much ozone you breath on a regular basis, working with so much air plasma. Ozone is amazingly harsh and may have chronic effects if you breath low levels over time.

Lot's of cool comments and ideas here. I don't have access to equipment currently, but for someone who does, here's what I'm picturing and can't get out of my head: Take the current turbine design, hanging under the wing, and gut it. With the shell, the housing we have left, a cup that compresses as its moves forward, and now all along the inside of the cup, scoops, spiraling towards the back, each with an internal thruster plane to pull air through it's channel, which exits a smaller outlet than the scoop, outside the housing. Lot's of thrusters, pulling air into scoops then through channels from inside to outside, all inside a giant compressor scoop. Any thoughts??

Try doing the edges in a circular fashion instead of 3 bars, the constructive forces will be much more focused like this, also possibly making it smaller could prove fruitful

Have you thought of trying an ion impulse thruster? Computer controllinging each stage to go on and off. Stage 1 goes on then simultaneously stage 1 goes off and stage 2 goes on etc… thru each stage. You can also have the computer (using an a/d interface) control the power levels of each stage. I suggest that you ramp up each stage. S1 10w, s2 20w, s3 30w and s4 40w. Using waves you can increase your thrust of your engine. Just a thought…

I wonder if you need to change your test setup, as it seems you are optimising for an incomplete set of parameters. 1. Add lateral force measurement. 2. Avoid ground effect. 3. Start tracking specific impulse vs weight 4. Add a known speed incoming stream air for apples to apples. 5. Design thruster aerodynamics/stages on the basis of incoming stream of air.

And keep in mind, velocity does not necessarily represent thrust. A turbo fan can generate more thrust at lower air speeds than a turbojet because of the volume of air that it moves and the static pressure that it can hold

[@clintcarpentier2424]

It's possible that the triangle shape is creating too much interference, causing the air to fight itself to get out, ie drag. I don't know how you'd test that though; confetti in a fire resistant room? Maybe try a box, with thrusters on just two opposing side. Or, if you wanna keep the three sides of thrusters, you could try the bestagon approach, and connect them with three equal blank sides. Likewise, you may wanna try containing the entire unit in a sleeve. You can get cardboard tubes of varying diameters at the local hardware store. For shits and giggles, you could try funneling the exhaust.
