That is a coil gun. A gauss gun is different. A coil gun uses coils to pull a projectile via magnetism. A gauss gun puts current through the projectile that causes a magnetic field between the two rails that pull the projectile. Guass guns don't have coils.

From the video, it's actually pretty small, about pistol sized. I don't know the engineering enough to judge whether or not you could expand that design from four stages to N, but I'm thinking a rifle length set of coils with the batteries and capacitors in a backpack might put it past the air rifle stage.

I got 250FPS out of a Mcdonalds straw, some spare wire and a camera flash. Granted, I was firing penny nails, instead of big ass slugs, but still.

Once again, the only reason that coil guns and rail guns aren't used in the military (much) is because to really get any output, it takes a LOT of power. It also takes a lot of specialized power gear to create the pulse form just the way it should be (I'm guessing this guy didn't bother with pulseforming) All that gear weighs a LOT, so man portable versions are either underpowered, or just too damn heavy.

Rail guns are different... all the same problems with the electronics, and in addition, the rails wear very very quickly due to plasmic electrolysis. Basically, they eat themselves. However, as a bonus, it's not hard to break the sound barrier with a big ass projectile. It's why the navy likes them. Over the horizon targeting, combined with supersonic projectiles combined with very very good ballistics... all together and you've got a really long range cannon with massive firepower.

Now, the military has come up with something even better. They used a linear accelerator (it's a ring) to bring .50cal ball bearings up to a very high velocity inside the ring. Then, when you hit the trigger, it releases 3-5 ball bearings down the barrel. The impact energy is 10x higher than a Barret 50 cal rifle at the same range. They are currently using these as Humvee mounted weapons in Iraq... or at least they were using a few as a test, I'm not certain how that testing went.

Anyone that wants to build a coil gun can. It's not even very hard. Can you solder? Can you handle Hicaps? You're good to go. Building a rail gun that actually works, that's a whole different ball game. The sensors this guy used wouldn't work, and generally speaking you have to use optical switching just to keep up with the projectile velocity. Also, your pulse has to be formed especially well, and in the correct phase variance. That is not easy or cheap, and especially it isn't light weight. Coil guns though, can be built with a disposable camera flash unit, a straw and some copper wire (15 gauge or bigger, you don't want liquid copper on you). That would give you a single stage unit. Mine got about 250fps shooting penny nails with the head ground off.

Hence the problem with electromagnetic guns at the modern level of technology, the power required to make them viable is huge, and we dont have the ability to make it portable in any reasonable sense. The military has made a railgun already, and the power system for it takes up a small building. Powder propelled shells are still more practical. Currently the US Navy is set to be the first to deploy one in a combat capacity, as a main gun on a ship.

This is one of the many things, along with electric cars, that will benefit from a huge jump in battery technology. Make a battery with 100x the capacity at the same size as currently available, and you will see cool stuff happen.

I don't know the engineering enough to judge whether or not you could expand that design from four stages to N, but I'm thinking a rifle length set of coils with the batteries and capacitors in a backpack might put it past the air rifle stage.


And then it would still be inferior, in every possible way, to this:

Very good, but he's only leveraged half the advantage of the Gauss rifle, which is obscene muzzle velocity. The other is obscene rate of fire, and his 8-shot semi-auto doesn't even pretend to, er, shoot for that. Possibly due to legalities, which wouldn't surprise me at all.

Unlike conventional chambering firearms, a full-featured Gauss rifle doesn't have any moving parts that are critical to the action, doesn't need to eject a sabot, and doesn't need to go through a reload cycle. It can instead operate continuously, firing literally as fast as you can get rounds into the 'chamber' (start of the raceway). A gravity-fed hopper magazine might achieve extremely scary rates of fire.

You may want some control over the rate of fire though, lest you send your hail of bearings out in one continous stream, and run out before you need to

Umm... No.

Your Crosman Phantom is a "1000 fps" .177 cal springer. Even a heavy 10 grain pellet at 1000 fps is only 22 fpe (30 joules) at the muzzle.

This thing claims 500 joules (370 fpe). That's getting into .357 magnum territory.

If you run the numbers, 4 18650 batteries (3.7V x 3000mAh) have enough energy to produce more than fifty 500 joule shots.

He's claiming 500 joules into the capacitor. That's not the same thing as 500 joules at the muzzle. The article says he's getting 100 m/s out of it. A little back-of-the-envelope math puts his 5.7x16mm slugs at about 49 grains, or 3.1 grams.

3.1 grams at 100 m/s is 15.87 joules. Roughly half what the Phantom produces at the muzzle ;)

That's an energy efficiency of just about 3%.

After watching the whole video, I have to agree. That's nothing close to 500 joules at the muzzle. I believe a 1000 fps .177 cal gun might just be twice as powerful.

I saw 500 joules total energy and assumed that was per shot.

Yeah, if it was possible to make a 7lb Gauss rifle with the power of a .357 in your garage, I'd be building one right this minute.

The real problem with coilguns is the energy efficiency. Based on what I've read, the upper limit for efficiency for a basic coilgun with a small number of stages is somewhere in the 3-5% range. Contrast that with 30-40% for today's firearms.

To raise the efficiency to something approaching a practical weapon, you need to start adding lots of coil stages and very fast switching mechanisms with precise timing, in addition to some really big capacitors, high quality magnets, and a power source to match. All of which drastically raise the price of the weapon. I think for the hobbyist market, the best you're going to be able to do is a 20lb rig that's about as powerful as a .22LR.

honestly, the biggest drawback to the coil theory is the coils. the pulses start approaching energy levels where inductance rears its ugly head and you start crushing the barrel as the coil deforms. there are ways around this but it's still pretty ugly. carbon fiber's out as it attenuates magnetic fields something fierce(nice to put over the body of the gun tho). even non-magnetic metals will form reactive eddy currents that degrade performance.

the upper limit on coil/gauss guns is really low, sadly.

now, i toyed with plasma conversion once... that was pretty exciting. dump enough energy into 1 gram copper pellet with magnetic induction and it turns into very energetic plasma... my wife never lets me forget taking the roof off the shed with the mark 1.

if you could get the plasma to stay roughly coherent at range, it'd be pretty ugly results on impact, with almost no recoil for the shooter.

granted the gun would be huge because the powerlevels are in the megajoule range...

more like green bolt of lightning and lots of sound and splinters raining down from the approximate 5-6' hole it made in the plywood of the roof. near as i can tell i had some focusing going on from the ring coil that was doing the energy transfer, and inductance in the baseplate squirted it up into the roof rather than letting it vaporize the workbench.

i'm just glad i was standing at the other end of the shop when it fired... from 10 feet away the heat was like standing in front of a blast furnace for a brief instant. had a bit of sunburn on the small patches of skin not covered by my welding gear.

if i could figure out how to efficiently direct and focus it, and keep it focused over distance, it'd be hellacious stuff at range with freakishly high velocity. not light-speed but damn higher than a bullet.

but that's a sidelined project. the current planning is for a LED array laser built out of scrapped optical drives. the fun part is it scales nicely if i can keep the optics properly cooled.

Kahabut: Now, the military has come up with something even better. They used a linear accelerator (it's a ring) to bring .50cal ball bearings up to a very high velocity inside the ring. Then, when you hit the trigger, it releases 3-5 ball bearings down the barrel. The impact energy is 10x higher than a Barret 50 cal rifle at the same range. They are currently using these as Humvee mounted weapons in Iraq... or at least they were using a few as a test, I'm not certain how that testing went.

I don't know the engineering enough to judge whether or not you could expand that design from four stages to N, but I'm thinking a rifle length set of coils with the batteries and capacitors in a backpack might put it past the air rifle stage.

And then it would still be inferior, in every possible way, to this:

If you used a heavy, subsonic projectile there might be a niche for Gauss guns as a silent weapon. The velocity wouldn't have to be all that high if you were tossing a 2 oz steel rod at somebody's skull. Maybe 400, 500 feet per second. That'd give you about the same energy as a .45 Colt but with twice the momentum. It would do Bad Things to a human, and being steel, would be more effective against light armor and obstructions.

That is, as long as charging the caps didn't make an incredibly loud high pitched noise. And you were willing to carry around a huge battery pack. To get 600J with 3% efficiency you'd be burning through about 500 mA-hr a shot from a 12V battery.

supercapacitors charge bloody fast and REALLY quiet. the downside is that their oomph is delivered at low voltage. if you could get them up to a few hundred volts you could more easily deliver the amps neccesary to deliver a shot with a fast quiet charge that's got the juice to do some damage. any supercapacitor array that charges to hundreds of volts is going to be impractically large.

/supercaps... low voltage, tons of storage.

trouble is, you need a flyback generator to charge at hundreds of volts. which makes lots of noise.

sure you could make a one-shot gun that's totally silent and disposable, but given that there's chemical based versions of those out there that are far lighter and cheaper...

EM-powered weapons as personal weapons are, right now and for teh forseeable future, the stuff of fantasy and wishful dreaming. we just can't get the energy densities AND discharge times with materials that can hold up to the load to make man-portable, much less practical EM guns.

which is a right shame.

MrTuffPaws: That is a coil gun. A gauss gun is different. A coil gun uses coils to pull a projectile via magnetism. A gauss gun puts current through the projectile that causes a magnetic field between the two rails that pull the projectile. Guass guns don't have coils.


According to Wikipedia, the term "Gauss Gun" is used to describe a coil gun. Link

Uhm, usually in scifi, railguns use a form of flechette round. Basically like driving 20-50 nails through most material at Mach 2-10. DU rounds might have less of an effect at those speeds.
 
2012-09-05 01:32:17 AM  
It looks pretty, but I am not impressed with performance.

And it does NOT NOT NOT NOT get those metal slugs going 328fps!

I have an airsoft rifle that shoots at 415fps - it puts little plastic pellets about the same penetration into a melon, and does even MORE damage to aluminum cans at close range.

In fact, part of me thinks that it isn't a coil/rail/gauss gun at all - just an AEG in a custom package.

Once I got the Sniper Rifle (and eventually the unique one... Christine's?) that was pretty much it. Upgrade it and keep the various ammo types on hand, and combined with a focus on the Guns skill and related perks, it's basically the only gun you need for any situation. Blowing the heads off deathclaws from a mile away.

I did climb up to the mountains ringing quarry junction once and threw in nukes with the Fat Man, just for fun.
