  It would seem that you can make a model of these without needing xenon or some other inert gas.

  Dude that's pretty rad, I didn't realize that Hall thrusters created an instability in the plasma. I've always been fascinated by Hall thrusters out of all the different types of ion propulsion. I've always really liked hall thrusters. So much to learn!!

  Excellent video makes the Hall Thruster easy to understand. I have been reading about this technology for years and the visual explanations have been lacking. I am even more impressed with the Hall Thruster's now

  Thanks for your awesome explanation. Couldn't help myself but to generate sounds "pop-pop-pop" in my head when I saw full thruster animation. I know you probably tried that, but I must ask. Have you tried training predictive AI model for such purposes? I know AI works fine for chemical and bio engineering tasks. It might work for your case as well.

  If we could use the Hall 2D software!!! We could also contribute more in this research with Krypton as propellant

  If we can’t simulate them, it’s probably advisable to avoid saying they are “widely used” in the first 10 seconds of your video. Other than that, great job.

  "Hall thrusters continue to be used on Russian spacecraft and have also flown on European and American spacecraft." So yea, they're widely used, it explains very clearly *why* they can't be simulated, and never claims they don't exist

  So is this a plasma thruster or an ion cannon or an ion drive? Is there a more popularized term to use than Hall Thruster? Just curious.

  Esse motor poderia incluir mais uma etapa de aceleracao. Assim que o plasma e formado deveria ira para um outro campo magnetico e assim ser acelerado como são os eletrons, isso faria o plasma atingir milhares de milhas em velocidade em vez de apenas dezenas de milhas, devido a aumento de velocidade o empuxo seria maior assim como o combustivel teria uma autonomia maior

  Na mesma linha de pensamento um acelerador de massa (Railgun, hyperloop) na lua poderia ejetar objetos a velocidades incríveis se acelerasse esses objetos em um circuito circular e só depois ejeta-los em direção a algum planeta do sistema solar. Vc consegue imaginar o qto isso seria benefíco para homem dominar o sistema solar? O qto isso poderia ajudar a entendemos melhor a física?

  Hi I hope that you are doing well You guys have pioneered a stellar feat in ECR thrusters Do you have any open source softwares or data driven techniques for simulating MPD or ECR thrusters I am having some issues with my dissertation if any of you could help me or have a chat It would be the best thing ever

  Hi Talha. We do not at the moment have any open-source models for ECR thrusters. However, Benjamin Wach's thesis describes a simple global model which may be of use. You can find it here: deepblue.lib.umich.edu/handle/2027.42/174254

  Recently India sent world's first hall thruster into space. Nice explanation in this video. thanks.

  @_colonial_2 ай бұрын

  Didn't the USSR do it in the 70s? The Soviets were big on this tech, while the West focused on grid-based approaches. (Of course, I have no doubts that the Indian thruster is miles better than anything produced by the USSR.)

  You make the same mistake, beginner rocket engine designers. The actual thrust is not in the ejection speed, reaction force is not the propulsion. In ion thrusters the thrust comes from the molecules, either neutral or ionized that hit the anode or rear wall of the chamber. Nested IT have more power because more rear wall surface is available. The grid on IT has the property of enclosing more atoms in the chamber hence increasing the chances of hitting the rear wall. To test that hypothesis, design an IT with the Noble gas inlet radially, injecting the gas at 90º to the motion direction into the chamber (now the gas atoms enter the chamber longitudinally, in the direction of exhaust). With radial injection of gas, thrust may be reduced significantly.

• 
  @jlfqam6 ай бұрын

  Did you measure any thrust with no electric or magnetic fields ON, just the Noble gas atoms flowing?

• 
  @jlfqam6 ай бұрын

  You overestimate the confinement power of the Magnetic Field, and excess e(-) move towards the anode. MCF cannot hold highly energized particles and will fail as a concept.

  This is a year old, so I don't know what improvements have already been found (KZread feed recommendation) but! What about pulsing pwm & electrostatic rail gun circuit approaches combined with a simplistic light wave interference model. I know they managed to use light pulsed in a given sequence top reduce quantum noise and randomness. Since electrons already carry momentum it then means we would be able to create a pulse frequency that improves, with the correct electromagnetic field reduction of flux strength and it's placement in the thruster (multiple coils, I'm sure it's already done but I'm the center and another in casing combined with smaller coils placed nearly end to end on top of those coils, outer diameter & inner diameter) worth electrostatic insulation, that can be switched on based on current and field collapse, that allows for electrons to be made to more likely hit certain gases fired in tightly controlled jets by the light and electrostatic forces. As the electromagnetic would help create a Lorentz force effect to them. The electrons then get controlled by which attractive or repulsive forces in a given area they are around, light enters such that photonic pressure occurs while having the electrons move towards the forces of the gases being charged or the given flux lines moved with pulsing various smaller coils to help the gases land in higher concentrations areas. It should them become a resonance acoustic thrusting pump using these fields effects and light pushing and pumping. Basically a inward bound pressure wave of electrons hits a gas pocket that then expands, it's then creates a gas pressure wave that bounces off a electrostatic wave that got moved towards the next electrons wave. My other channel has some programming upgrade ideas in it, but it would take even more writing, might check out the CPU combo playlist for that

  Is there any fuel or propellant used on this? The ETs have this sort of propulsion fully sussed. They don't need propellant, just massive TeVs. Hint: Rodin coil - which is to say, a properly formed Rodin coil, which is not quite how Rodin constructs it. And room temperature superconductors. You can get good results with the right coil, the superconductors just improve efficiency.
