Dread Gun

This is a quick demonstration of the Dread gun.
For those interested, Google Trinamic Technologies, or Dread Gun.

this is impossible

[Kaiwynn]

Welcome to 3 months ago.

Nice of you to show up.

PS: Check the comments. Many people have said the same thing, and backed it up with evidence.

[Xezlec]

It's no accident that this video never shows the device working even once. It's because it doesn't exist, and never will.

This gun claims to violate not just one, but several laws of physics. The Law of Conservation of Momentum is absolutely fundamental; it can never, ever be violated, no matter what. If you give a bullet momentum, you get the same momentum in the opposite direction, no matter what your device looks like or how it works. Recoil from a projectile weapon can not be avoided.

[Kaiwynn]

Well I've said it twice now in this thread alone, its probably test footage for a company looking for backing, hence, no actual footage.

Since theres no tangible gun, I would assume its probably in early R&D. More emphasis on the "R" than the "D". Thats all providing its true.

But check out Wikipedia, and look up "Coilguns" It seems to me a Coilgun works without Any recoil whatsoever. Maye its the basic principal for this idea? I'm no expert so I don't know.

[Xezlec]

I apologize for the multipost. I thought comments showed up quicker than that.

I don't know where you heard that a coilgun has no recoil, but that's absurd. If you can figure out a way to build a magnetic coil that isn't pulled toward a metal object the same amount that object is pulled toward it, I'd be impressed. And so would Newton's ghost.

This person appears to be a typical physics-illiterate nutball trying to get money from the government. It happens a lot.

[Kaiwynn]

No Problem. I use Firefox so it was natural to see Youtube be all kinds of messed up.

As for not knowing were I got it, I listed alot of links in the Description of the video, not to mention the wiki page for "Coilgun" that I mentioned that states exactly how a Coilgun works. I don't see any way for there to be recoil, but, again, I'm no expert.

Did you at least look at it?

This principle works. I've seen it. A friend of mine once had a toy with a trigger which spun a centrifuge and threw bbs through a barrel. The power was much greater than you'd expect from only finger power. Also I remember reading ads in a biker magazine for a simillar product which used freon to spin the wheel. A friend of mine had one. It was much more powerful than a bb gun and with hundreds of bbs hitting you all at once could have been lethal.

Half a year later... and what do you know: this myth is as dead as it was from its inane conception.

[mkarnerfors]

(Post 3) Then there are the gyroforces making it impossible to aim; the extremely poor ballistic coefficient of spherical ammunition which makes the DREAD as harmless as BB gun for ranges over 300 meters; the utter stupidity of having a flywheel spinning at Mach 3 (silent? not really) at the edges waiting to fracture like an omnidirectional claymore when hit by enemy fire... and finally: the complete lack of credible sources for this.

In short: It's a hoax.

[mkarnerfors]

(Post 2) So, you have to take that remaining projectile that is going full speed the wrong way and turn it around. That will be two recoils. One to "stop", then another to get going in the right direction.

Then there's the issue of power. With all the "kindest" values clamed with this weapon, when firing, it will have a power requirement of 500 000W. That's right... half a megawatt, or 680 horsepower. And this is still assuming perfect power conversion and no friction losses.

[mkarnerfors]

(Post 1) It's a hoax. Some of the claims are physically impossible. Others greatly exaggerated, and the video does not bring up some of the gross impracticalities with the weapon.

First of all recoil: there will ALWAYS be recoil. In this case there will be *triple* the amount of normal recoil. First when you spin the projectile up to speed. Then when you release a projectile, you will have an unbalanced flywheel because of the projectile on the other side of the turntable. -->> (Post 2)

[Xezlec]

Nope. Every force in the universe operates on two objects at once, equally, but in opposite directions. This law is absolutely fundamental and can never be violated. Also, "centrifugal force", in the sense in which you are using it, is a myth. The object is simply accelerated forward during the part of the rotation in which the end of the rotor is moving forward, and is then released. The device turning the rotor is accelerated backward at the same time as it pushes against the projectile.

[centurion10000000234]

the reason there is recoil in a firearm is because the gas pushes against the back of the bullet and the bolt face. this weapon uses a different kind of energy. the ball is pushing against the outside of the rotor and then it is simply released. the only forces are centrifugal. if there is anything resembling recoil it would be from the balls on the opposite side not being counterbalanced once the balls are released.
