A gun that spits out ball bearings after spinning them to extreme speeds is being developed by a US inventor. The novel design has already caught the imagination of some defence industry experts.
The weapon, called DREAD, was invented by Charles St George, a veteran of the US firearms industry who founded the company Leader Propulsion Systems to promote the idea. He claims a major US defence company has shown an interested in developing it further and has produced a promotional video showing a prototype in action, which can be seen here (Quicktime). He says a new prototype will be developed in August 2005.
The gun consists of a mounted circular chamber that spins the metal ball bearings to high speed. A release mechanism on one side spits the balls out one behind the other, a handful at a time.
St George says the projectiles travel at around 300 metres per second upon release from the weapon, about the same speed as a handgun round. He claims a fully developed DREAD gun would be quieter than a conventional gun, less prone to malfunction, and could contain more ammunition.
DREAD also releases its balls in extremely rapid succession, which allows it to unleash formidable firepower against a target. Promotional material for DREAD states: "Due to its extraordinary high rate of fire capability, it delivers its bullets 8.5 millimetres apart, thereby delivering more mass to the target than any other weapon."
Overwhelming and devastating
St George would not specify the range or accuracy of the most recent prototype or explain precisely how the system works, because he says this information could be commercially sensitive.
But a patent issued to him in February 2003 has been found by Marc Abrahams, editor of science humour magazine Annals of Improbable Research. It refers to a "Weapon for Centrifugal Propulsion of Projectiles". In this design, balls are stored inside a series of narrow chambers that radiate from the centre of a circular chamber and which are rotated with the chamber at high speed.
A mechanism beneath each narrow chamber automatically manoeuvres a single ball into a smaller compartment at near its edge. When the trigger is pulled, these balls are released into a guide rail and shoot from the disc rapidly, from a hole at its edge.
"The system seams absolutely feasible," says David Crane, editor of the website DefenseReview.com. The weapon could strike targets with “overwhelming and devastating firepower - we're talking about total target saturation."
Terry Gander, who edits the defence industry journal Jane's Infantry Weapons, adds that similar concepts have been developed in the past. But Gander notes that these have had low projectile velocity and have been proposed as crowd control weapons. "It all depends on the sort of power source you have," he told New Scientist. "I'd be very interested to know what its range is."
But Abrahams finds the idea outlandish. "Anything that seems so far beyond anything else is worth a moment's thought before you completely gulp it down," he told New Scientist. "It is way out on the side of the scale that deals with high levels of imagination.
I would think the more accurrate discription would be the recoil would be more of a steady "push" vs. bang!(recoil); bang!(recoil).
A killer pachinko machine?
"That, and the power/energy requirements for spinning the chamber would be much larger than what a typical handgun/firearm currently uses."
Perfect for a satellite. Just crank it up and leave it on --- essentially forever.
Except now you have to deal with Newton's Third Law: as the weapon spun in one direction, there would be a tendency for the platform to begin spinning in the opposite direction -- not rapidly, but enough to make Zero-G combat a rather hairy proposition.
Centripetal?
"Shooting a round ball, I would think it would not be overly accurrate or have much of a range in the atmospher."
I guess that depends on whether there's any type of "rifling" or not. Them buckskinners of yore held 1000-yard matches with muzzleloaders, eh?
Anyway, let me add: I want one :^)
The modern version of the sling with which David slew Goliath.
Good catch. Some great lines in that movie.
Your car tire is a centrifugal weapon when it throws a rock out of its tread into your fender. Similar recoil, or lack thereof, for the weapon in this article, too. It's actually negative recoil, as mass is leaving because it is released instead of pushed...you'd be hard-pressed to feel such minute negative recoil, though.
There's nothing in the Newtonian world we live in that would allow a violation of that.
Sounds like a power hog.

The tendency would be small. You actually have two opposing and offset rotations going on at the same time. See my explanation of the spiral barrel.
I dunno . . . I think it'd make me kinda nervous . . . What if a bearing burned up and it blew up? 'Course, like Frohickey said, you could start it up every time you needed it. Would take a couple of minutes to get up to speed, though, useless for self defense. And you'd still have to carry some kind of motor around with you! :-)
Amazing they don't know a little more about physics than they do over at the New Scientist!
Maybe I should just go to Sears and get a Craftsman screwdriver...
