Thank you! Though I don't think this design is fully optimized just yet though, as all the coils are the same. When mapping the field of various coils with my CNC, I had to manually increment the Z height by 1mm, and then actually write down the inductance and field values in a chart. So I got lazy, and just used one coil rather than optimizing a new coil for each stage. I do, however, have an idea for an automated field mapper that would increment the stepper motor, read inductance, read the field strength, and then send the resulting values to my computer to be automatically entered into a spreadsheet. That would make the optimization process much easier.

As a firearm guy I'm a big fan of your setting to drain the power from the weapon to make it safe so it won't shock you. You didn't have to make all the extra programs and devices that helped you make the rifle but it's amazing that you did. It's a great idea for making a 2nd iteration or making others for someone else.

you also have to drain the power because it would become very dangerous, the capacitors could explode after some time.

Coil guns are rather unintuitive because a smaller projectile will not necessarily go any faster. The reason for this is that a smaller projectile has less metal mass for the magnetic field to pull on.

Impressive job, well done. Here are just some advice that might help you since I worked a lot on coilguns for my uni project. Try using some washers at both ends of the coils made of epoxy and ferrite.and also try to minimize the airgap between the barrel and the projectile.and don't underestimate the effects of good aerodynamics on the bullet. you can also use a stepped coil geometry for the first coil, and since the projectile passes the the coils with different speeds, you may wanna use different inductance and capacitance values for each stage. Nevertheless, excellent job.

Would using a modified version of something like these make for better coils for creating a stronger field as well as being able to cool the coils?

He has to scale up the output by an order of magnitude to even meet a .22, which is widely considered the bare minimum. Two orders of magnitude to reach the sort of output we already get out of a package that size. It's cool, but nowhere near useful.

I am very impressed by your efforts to characterize and simulate the electromechanics, especially the accuracy of the predictions. Did you simulate the back emf from the moving magnetized projectile? I assume the energy transfer would show up in the coil as a back emf and be dependent on the velocity. Did you simulate this much detail, or just assume a simple capacitor/inductor circuit? I would be really interested in an in-depth explanation of your characterization and simulation process.

@BenjaminMarshallScienceMan

Thank you! The simulation accounts for the projectile increasing the inductance of the coil, and also the energy stored in the coil aswell as the resulting back-emf across it when the IGBT turns off. The one thing it doesn't account for is the hysteresis of the projectile inducing a current in the coil.

@BenjaminMarshallScienceMan

2 жыл бұрын

One possible avenue for extra performance is mentioned in my design guide, though I was having trouble simulating/building it. You should be able to redirect the back-EMF of the coil at the end of the shot into the next stage with a diode. This would result in the next stage experiencing a voltage spike right at the beginning of firing. Such a voltage spike would serve to get current flowing through the coil more quickly, thus building a field more quickly. It also has the advantage of drastically reducing the fall-time for the previous coil since you dont have a flyback diode causing the current to loop through the coil.

I actually incorporated temperature into my simulation after making this video. Reducing the temperature of the coils down to 0 degrees celcius only had a miniscule impact on final velocity. I think I'd have to get them much cooler to see any serious improvement. As for superconductors, unfortunately copper doesn't superconduct at low temperatures like other metals. And building a coil out of superconducting material is a bit outside my skillset at the moment.
