  • If jet turbines are the evolution of a propeller, what is the evolution of ionic thrust? In my attempt to answer that - I built a next-gen ionic thruster, and only shocked myself about a dozen times in the process. Thank you to Steven Barret at MIT for providing his airplane footage, and to Keysight for supporting this video.

    My thoughts on improvements:
    1) Ducted airflow. Preventing air from moving out of the system until the end.
    2) Adding a nozzle. The airflow velocity increases due to the constriction of the tube radius, therefore after the acceleration, you could decrease the tube radius to give more thrust.
    3) Adding barbs to the emitters. Charge accumulates more intensely in sharper locations and will be emitted more freely.
    4) Magnetic fields. Given the charges passing from one area to another are known, having solenoids creating magnetic fields around the ducts that induce a more significant flow would help the movement.

      Which goes back to this things main problem. Lots of weight, little to almost no thrust based on the weight.
      Also why it is considered in space flight for long mission probes. It can get up to fast speeds but because it have almost no thrust it's gonna take months/years to get there.
      IE: It will never produce enough thrust to power a plane on earth.

  • @DominoSixO
    @DominoSixO ปีที่แล้ว +100

    Add the entire build in a
    1. tube, it will increate the thrust theoretically as it will create a pressure difference,
    2. as well add at the input a donut shaped intake it will make another pressure difference
    3. to pull more air, another thrust boost is to increase the tube incake and add some holes on the side, similar design as the blow torches which pull air from sides based on the pressure
    Hope you read this, i wanna see it in action :)

      Hi. Mechanical Engineer here.
      1. He should make a venturi tunnel. The different diameter of the tunnel creates an high pressure zone and a low pressure zone which can be used to place the engine at the perfect spot along the x-axis to take advantage of the venturi effect.
      2. The donut doesn't help drag more air in, it reduces drag of the air that is about to be sucked in by reducing tubulence.
      3. The airholes in a blowtorch use the same theory as a spraypaint gun. The pressure difference are created by the speed of the gas in the main chamber. Fast speed of gas makes the pressure smaller, thus sucking the air in the small hole at atmospheric pressure into the main airstream. In a paintgun It would be the air compressor air moving vwry fast, and in the smaller hole you have your paint resorvoir at atmospheric pressure veing sucked along with the pressurized air..

    1. You would have covered the sides so that air current won't leak,

    • @operator8014

      A constant DC PSU probably wouldn't have worked, since you need super high voltage peaks for the plasma discharge. The pulsing supply allows for waveform collapse, which produces huge voltage spikes, just like an ignition coil from a vehicle.
      So unless there is a super simple 100kV DC PSU out there, the pulsed supply is the way to go.

    Inefficiencies:
    1) Ion path scattering. Position the electrodes so that the ions all flow parallel, ideally. Otherwise their non uniform direction makes the overall thrust vector hit the wall of the device which eliminates much of the airflow.
    2) Ion pathing. A dielectric rod ending at an oppositely charged sphere or grid will make the ions want to flow towards it, thus preventing them from diverging. Otherwise they may get attracted by other charges around the device and make the air diverge. Ideally, enclose the whole air flow to have control over what your ions are pushing and to recover a portion of you spent energy via the sphere/grid.
    3) Electrode shape. Round them up on one side to make charge (and air) only flow the other side. Use needles. Otherwise ions will set up tiny back currents to the opposite direction.
    4) Materials. Use hollowed frames to reduce the weight (which decreases thrust) by a lot. Good ones are Expanded Polystyrene and Kapton tape. Don't wait for Graphene windows.
    5) Temperature. Use thermionic emission to get more ions. Cheap tungsten needles do exist. This is not an inefficiency btw, more like an improvement.
    6) Air channel geometry. Close the walls to protect against side air currents. Otherwise air may not flow linearly, especially if ion path scattering is not dealt with. This necessitates that you build an appropriate container to facilitate smooth flow otherwise air can get stuck momentarily, creating "traffic" that may slow down the net flow locally thus reducing thrust.
    7) Gravity. Always position the apparatus so it blows downward to take advantage of gravity, otherwise it is always eating away at your thrust as it doesn't let the air flow in line with the cylinder. Thermionic emission may fix that up a bit as hotter air tends to rise. You need to find the perfect balance with these two.
    8) Another improvement. Use Integza's golden spiral fan to set up two air vortices that serve to both push as well as pull the air to and from the desired direction, and help counteract the side effects of both gravity and thermionic emission.

      @@yummyhershey5902I don't think batteries will be the solution for this technology. Using fuels to provide the energy density needed for electrokinetic propulsion will result in drastically increased fuel efficiency. Check the Thomas Townsend Brown patent for the electrokinetic flame jet generator. You can get several million volts with a traditional jet engine running kerosene, if you ionize the exhaust and then collect the accelerated charges at the end of a nozzle and feed the excess power back in to the exhaust at ever increasing voltages. Ion thrusters efficiency can be as high as 110 N/kW or more scaling with voltage, so augmenting a normal flame jet would increase the efficiency without drastically lowering the thrust. In fact because the system is efficiently converting chemical energy to electrical, and then recycling it to generate higher speed, higher voltage exhaust, there is a net gain on thrust as well as efficiency. Brown wanted to exploit the ionized gas cloud left in the exhaust to form the negative electrode for the ion craft, to drastically increase both the voltage and the electrode gap between the positively charge ions generated at the leading edge of the airframe and the negative cloud. This works fantastically well in the upper atmosphere/ionosphere, where the ionized air is influenced at a long range by the high voltage. This can be further augmented with magnetic field control for additional power recovery during descent. See also the work of Jean Pierre Petit PhD, who shows how Magnetohydrodynamic engines can manipulate the skin plasma around such craft to achieve supersonic speeds without generating sonic booms.

    1. Put the "engine" in one sealed pipe with open ends, you have air/pressure losses on the sides.
    2. Make it shorter, the longer it is, the more ineficient will be. Use 3 separate HV generators, 1 for each coil, and reduce the "engine" size from 50 cm to 10 cm. If it is done properly, the HV coils shouldn't interact with each other, even if there is 1 cm spacing between them.
    3. Use a thermal camera to see the flow of the air. See if the temperature of the air (in) hot/cold-dry/wet-low/hight density, influence the output pressure.
    4. Apply the same principles in jet engines-air compression-, start with a big fan(coil) , than a middle one, than a small one at end to increase the pressure.
    5. Chance the shape of the coil. I would say that if your thruster coil have the shape of a triangle vortex(such as a tornado), will dramatically increase the pressure. Use only 1 coil long enough to create the electrical/plasma vortex.
    6. Use a magnet with donout shape at the end to see if he concentrate the plasma flux in one point, thus increasing the pressure.

But if he could accelerate the same air 3 times, and twice the Air speed. He gets 4 times the kinetic energy. Although I agree with another comment on here, where the voltage steps up from stage 1 to stage 2, and functions similar to a turbo engine where the air gets compressed (loaded with more potential energy) as it travels down the stages.

I am not to sure if sucking in aditional air will improve the thrust and eficancy for the ion thruster. There is no expansion of air or moving parts like in a jet engine.

      Also do we really want the positive to be the thin wire ? If the thin wire is negative it’s going to ionise air much easier since electrons can leave it faster.
      Also-also, I think more stages will improve air speed and one should consider making the attractive plates slightly longer and with spikes at the end so the air is ionised with the opposite charge near the exit and attracted to the second stage. In fact, you can make everything from thin plates with many spikes at the end and ditch the thin wire altogether. Shorter plates for negative side and longer for the positive one. That way it will act almost like an ion accelerator. Of course, the width of the plates should be optimised depending on the intended airspeed. The faster the air moves the less of it (proportionally) gets ionised at any point.
      Also, higher voltage and more distance means more ion acceleration with the same amount of materials.
      The air also probably gets heated up a little at each stage so after enough stages the air blower might start behaving more like a jet engine with hot exhaust. Compared to a turbo jet this acts more like a 2-in-1 turbine and burner.

      The reason i would not use a magnet for that is the you want to create somewhat of a laminar flow of air through the tube but a magnetic field around it would either pull the electrons to it or push them away.
      lets say it pushes them the they would al go to the center. this would increase plasma density but also decrease the surface at with the plasma contacts other air molecules to make the move along.
      where the idea could work is a sort of an afterburner if you slowly decrease the tube area until you get a smaller tube where the plasma created is pushed down the tube with several solenoids like a small particle accelerator of sorts. that small tube could the go into a bell nozzle or aerospike to turn the pressure back into velocity. the only thing would be cooling the whole thing when in use and after

    Honestly the open design is probably lowering the efficiency quite a bit. The air pressure behind each stage is higher than in front which means it will be leaking out from behind each stage. Really excited to see the full ability of this new idea. I encourage you to experiment with harmonics and pulsed voltages because you may be able to find a resonant frequency of the ions traveling from the positive side to the negative side. My theory is to try finding the average time it takes for an ion to pass from one electrode to the other and match the pulse rate with that. Of course, I could try this at home myself... eh, probably best I don't. Very nice work here, thank you for the content.

    The staggered thrust solution reminds me of how different turbine blade pitches throughout the stages. So each stage could accelerate airflow as it passes through.

    • @akumabito2008

      Could be worth trying to run each stage on a different voltage - it might not improve thrust, but maybe it would decrease power consumption.

    • @N8riz

      For turbine engines the compressor stage slows down air flow and increasing PSI. With a combination fan stage (2ndary/bypass) airflow which gives it thrust when adding all that with fire and fuel mixture.

  • @GuillemBagaria
    @GuillemBagaria ปีที่แล้ว +16

    Congrats, these are amazing results!
    I've had some experience with corona discharge. My suggestions:
    - Increase the "sharpness" of the anode by adding spikes to the wires.
    - Enclose the thruster in a duct and maybe add a nozzle to increase air speed.
    - Measure the current into the cathodes (with a high voltage probe). It should be ~0. When the dielectric breaks so does the field gradient, and ionization drops. Finding a combination of voltage, distance and electrode configuration to reduce cathode current should reduce the power consumption and improve efficiency.
    Good luck!

    • @YonatanAvhar

      @rich1051414 ปีที่แล้ว +2

      A high dielectric constant is fine, but acrylic is heavy if it's going to be used on a plane. Ionic thrusters have low thrust, so the frame needs to be as light as possible.

      Unless you're talking about the ions in water vapor and rain drops? That's three layers basically like a diode/capacitor.. PTE film(plumbers tape) as a seperator. Aluminum foil as an anode top layer and I believe the cathode is copper underleath. I'm sure the cathode doesn't matter as much you could probably use aluminum foil and PET on both sides like a Uindhurst static motor and still get a current. The only problem with this is unless you have a laser cutter the individual cells would be a pain in the as to make individually if wanted to cover your roof with. Per square meter roughly the same power output as a solar panel during a rain storm. The energy I believe is triboelectric meaning it has to be managed in capacitor banks and conversion coils before being converted to a usable square wave AC. But totally doable. There's also triboelectric voltage difference potential from atmospheric v gradient. It requires a long thin wire suspended high in the air.

    I'd like to see blade shaped negative poles.
    Also, it would be interesting to see a venturi shaped tube shape. Basically, the forward and aft thrusters larger in the front and back of the venturi with a smaller diameter thruster in the middle.
    Maybe offset the angle of the wires to the following thruster. Basically 33° between each. It might create angular flow through the venturi.

    Add a bellmouth inlet, cover the whole assembly with a tube, and add a converging nozzle may also increase thrust noticeably. Test and experimentally determine the optimal staggered spacing for each stage too, since the air is flowing faster after each stage.

    • @lizard_girl

    • @matus1976
      @matus1976 ปีที่แล้ว +2

      @@lizard_girl Yeah it might not do alot, but my understanding is that part of the additional thrust from converging nozzle cones comes simply from the higher velocity/lower pressure air inside creating a pressure difference to the air outside, and since the nozzle has an angled cone, you get a force pushing perpendicular to the nozzle angle, one component of which is along the axis of the thruster. Might not do much at all or hurt the overall performance as you suggested, but it seems simple enough to 3d print and try.

    2) on the areodynamics: REDUCE the cross sectional area of the ground electrode or even change the shape of it (cylinder to symmetrical airfoil to)
    3) SET UP: Instead of placing the 3 "Generators" in series, place them next to each other (in parallel)
