Kira Natel	Posted - 2006.07.27 01:06:00 - [91] Originally by: Leonstein Railguns utilise Coils or Rails to achieve acceleration of a Magnetically affected mass (Usual Nickel Slug) to extreme speed, due to the speed of the projectile involved the mass can still be very small and yet carry massive damage...So the power supply will have to be huge (The BS Reactor as mentioned) but the gun could be very small, possibly only a couple of inches in bore. The theory of Guass Cannons (Coil Driven) or Railguns (Rail Driven) is well old, so its not a BIG shock they've got it on the way The whole thing was started by some German Prof. called Guass, thus the Guass Cannon... Isn't Nickel non-magnetic? As are most metals. There has to be some amount of a ferrous metal (iron) for electro-magnetism to work?
Aeina Caeraen Caldari	Posted - 2006.07.27 04:36:00 - [92] Nickel, the element, is ferromagnetic and similar to iron in that respect. A US "nickel" is not magnetic, as it is actually mostly copper in composition :P
Jacxx	Posted - 2006.07.27 04:55:00 - [93] Here Iam posting in this thread again. A metal doesn't have to be ferromagnetic to work in a mass driver (I like that term more then coilgun, they are the same thing). There are two types of coilguns, reluctance and induction coilguns. -Reluctance uses ferromagnetic metals, where the projectile is accelerated towards the center of the coil through a pulse of electricity. -Induction coilguns use non-magnetic metals. Typically aluminum. They work by REPELLING the projectile. They are placed past the center of the coil, protuding towards the target. The coil is pulsed very quickly, this induces eddy currents onto the surface of the bullet, these currents repel the magnetic field coming from the coil thusly accelerating away. This is actually slightly nicer for multistage designs, since you don't have to worry about turning the field off in time as you do with reluctance coilguns, which can suffer from suckback if the field lasts to long. However aluminum doesn't make very good bullets, so you run into some problems there. It's to soft and very light.
Jerry Jones	Posted - 2006.07.27 11:42:00 - [94] Jacxx is right a electromatic does not have to have a ferrous metal to work any metal of which current can be inducted into can become a projectile. This concept can easily be shown py taking a 60Hz coil sticking an iron bar about the same size of the inside diameter of the coil and attempting to push an aluminum ring on th the bar you can hold it there for a lil bit. As soon as you let go though probally cuz it is now burning your fingers. The aluminum ring will shooot of off of the iron bar.(make sure coil is plugged in and has power) Thus demenostrating eddie currents.

They aren't nice to ignorant newcomers though. Beware.
Justin Cody Caldari	Posted - 2006.07.29 01:27:00 - [97] Originally by: Velsharoon Originally by: Scoundrelus Edited by: Scoundrelus on 25/07/2006 00:25:16 w00t! New and improved ways of killing people! Just what this world needs. Thank you USA for not curing Cancer and making more weapons. Set your priorities straight. Yep its a shame, especially when they allready dominate militarily. Such a waste oh great so now we have to do EVERYTHING for you huh? And besides we like weaponry. Metalstorm by the way is an Australian company contracted by the US DoD. As far as the railguns (EM guns) go, the major physial problem is that the round travels so fast down the armature of the weapon that the plasma wave welds the round to the rails effectively ejecting some superheated gas out of the barrel and killing the weapon...But have no fear there will be a solution soon..probably some kind of carbon resin with metal embedded...who knows. I for one won't apologize for my nation's excellent contributions to science especially in the realm of erectile dysfunction. I think all women and men should love U.S. Pharmaceuticals for this reason alone. We will be the ones to cure cancer by the way, you may continue doing nothing to help. Thanks. Remind people that profit is the difference between revenue and expense. This makes you look smart. Scott Adams

I think all women and men should love U.S. Pharmaceuticals for this reason alone. We will be the ones to cure cancer by the way, you may continue doing nothing to help. Thanks. Edit: The armature creates the Electromagnetic Force, it is not the rail or barel itself necessarily. Microscopic imperfections on the rails as well as the armature are vaporized when the rails and energized, since their resistence is so low as to be non-existent, firing currents can reach upwards of 10 thousand amps on smaller guns. More then enough to vaporize copper, steel, or pretty much anything short of tungsten. The speed of the projectile has nothing to do with its likelyness of welding. Infact, by practice, injecting the projectile into the rails helps to prevent welding, since it doesn't remain in contact with any one place on the rails long enough to weld into place, causing the projectile to almost "ride" on a wave of plasma. You can test this by touch the leads of a small capacitor, such as a photo flash capacitoe, together after charging it. The wires should spot weld together, probably not substantially with such a small pulse, but noticably. This is the same thing that happens inside a railgun, except on a smaller scale. The armature itself does not neccessarily make the electromagnetic force. The capacitors for a railgun are always discharging, albeit slowly. The bullet only accelerates this discharge, amplifying the EM force. This doesn't apply to the coilgun at all however, since the bullet is only a way of changing the EM force into Kinetic. If there's no bullet a field will still be formed around the coil. Lastly: The railgun is one amidst many "EM guns". Least efficient by far. But if you are going to talk about an EM gun, please use the correct term. To many people refer to everything that uses an armature to convert EM to linear kinetic force as a "Railgun". It's quite annoying.
Justin Cody Caldari	Posted - 2006.07.29 03:54:00 - [99] Edited by: Justin Cody on 29/07/2006 03:55:02 true, an rail gun is not the only type of EM gun,however it is in the category and while not alone it is one of the more popular weapons in sci-fi and in reality. what I can't wait for is the next generation of plasma-kinetic weapons which will be very interesting. edited for spelling Remind people that profit is the difference between revenue and expense.

Justin Cody Caldari	Posted - 2006.07.29 04:18:00 - [100] taken from U.S.Navy's library on the internet 'Sovinec, C.R. and R.E. Peterkin, Jr. "Phase 1B MARAUDER Computer Simulations-Formation of Plasma Torus." Weapons Lab., Kirkland AFB, NM: Weapons Laboratory, 1990. In: Conference Record - Abstracts. 1990 IEEE International Conference on Plasma Science, Oakland, CA, 21-23 May 1990. p. 167-168. Abstract: Summary form only given. The MARAUDER (magnetically accelerated rings to achieve ultrahigh directed energy and radiation) program at the US Air Force Weapons Laboratory is a study of magnetically confined plasma toroids that will convert stored electrostatic energy into plasma kinetic energy. The first phase of the experimentation only forms the toroids and does not attempt to compress and accelerate them. Magnetohydrodynamic (MHD) calculations have been performed with the 2-1/2 dimensional code MACH2 in support of this phase. The simulations demonstrate the formation of the torus, including reconnection of the poloidal magnetic field components. Number densities in the toroids are on the order of 10/sup 16/ per cm/sup 3/, and the magnetic induction is on the order of 1 T. A series of calculations shows that only a limited range of discharge energy will produce toroids. Too little energy will not push the plasma through the initial, injected poloidal field; too much will not allow a good reconnection.'

xeom Obsidian Sins	Posted - 2006.07.29 04:53:00 - [101] Cool more ways for mankind to kill each other in mass. CCP where are our t2 shield power relays? \| Join[..SIN]
Michiyo Daishi	Posted - 2006.07.29 11:56:00 - [102] More proof that USA is playing EVE and also in line with the most broken race in EVE, Caldari. US got the lead in their missile technology (Tomahawks) in the early 80's. Who does that sound like? And now railguns? Does it need to be spelt out more? - posts posted are not official statements of EVEnews.com, and are the poster's own

Krulla Minmatar	Posted - 2006.07.29 12:32:00 - [104] Edited by: Krulla on 29/07/2006 12:32:33 I'm not sure what disgusts me more, the fact that these things are being built, or the fact that all you people are going "omg! Cool! It r just liek in eve lololol".. Those are not cool. Those are horrible weapons, designed to murder people. People like you and me. Railguns are cool and flashy in computer games, but in real life, no thank you.
Tsun Lao	Posted - 2006.07.29 15:42:00 - [105] Great. The US just wants us to love them, not only do they have the urge to invade and **** up countries, but they also create MORE weapons that allows you to kill people more efficient. God bless the United states of america

The US just wants us to love them, not only do they have the urge to invade and **** up countries, but they also create MORE weapons that allows you to kill people more efficient. God bless the United states of america Because, you know, the US is the ONLY country in the world that could possibly be working on building bigger weapons! Every other country in the world are just little and peaceful and completely devoid of corruption and any idea that violence is a neccessary evil! Blasphemy! Just those big bad americans always causing problems! And Krulla: Yeah designed to kill civilians like you and me. That's all these weapons could possibly be used for, mowing down innocent civilians right? They couldn't possibly be accurate and strong enough to eliminate precise people from hundreds of miles away. They definetly wouldn't be used on an enemy military who would kill YOU the civilian, or any of our own military without a seconds thought. There can be no good coming of a more efficient weapon. Seriously, the US has some.... okay, many, government related problems, Im not gunna lie. But don't assume that everything we do is done for some kind of evil purpose of taking over the world.
Tsun Lao	Posted - 2006.07.29 18:15:00 - [108] Originally by: Jacxx Just those big bad americans always causing problems! Yeah, the way things are today this is quite accurate. Quote: They couldn't possibly be accurate and strong enough to eliminate precise people from hundreds of miles away. Biggest problems with weapons today is just that, that they enable you to kill people hundreds of miles away. Quote: They definetly wouldn't be used on an enemy military who would kill YOU the civilian, What about the 100k civilian casualties from the Iraq invasion eh?

Perhaps we should go back to trench style wars where hundreds of thousands died brutally? 3: Some kind of a source for that statistic?
Tsun Lao	Posted - 2006.07.29 20:36:00 - [110] Originally by: Jacxx 2: You prefer wars in which many people from both sides die eh? Perhaps we should go back to trench style wars where hundreds of thousands died brutally? Yeah, because it might prevent retards into voting even more retarded people into power.
Justin Cody Caldari	Posted - 2006.07.29 21:12:00 - [111] lets keep politics out of this thread if we can... I've made a new one just for that here Remind people that profit is the difference between revenue and expense. This makes you look smart. Scott Adams

Because wasting human life is totally worth trivial politics. Besides: He's out of office in like 2 years, which is the exact reason we have the 2 term rule. War is inevitable, be it with good cause or not. I for one support a way in which to wage it with minimal losses, or atleast minimal unneccessary losses. Collateral damage is the very reason we don't use nuclear weapons, I'll be very happy when we don't use bombs at all.
Justin Cody Caldari	Posted - 2006.07.30 01:56:00 - [114] please get back on topic, this is a thread about railguns not U.S. foreign policy. I would be happy to take it up with anyone in game, but please get back on track. What will be even more interesting is when they have scaled the railguns down far enough to be mounted on our main battle tanks, and later...perhaps gauss rifles for soldiers. Remind people that profit is the difference between revenue and expense. This makes you look smart. Scott Adams
Amara Sei	Posted - 2006.07.30 02:39:00 - [115] The source on the "100,000" claim is the Lancet, just as a point of fact, one of the most well-respected medical journals in the world. We should probably be back on topic now...

Borothis Quishir V I R I I Center for Disease Creation	Posted - 2006.08.06 01:03:00 - [118] Im gonna deviate a bit from the weapon aspect to the power aspect of some of these weapons. I was reading an article in Popsci that was about battiers capable of running cell phones and labtops longer then the current batters can. The wierd thing is they are as thin as a piece of paper .003" or .076 mm thick. The way they made these batteries is by creating a virus with that contained a certain charge and then coated it in some metal. its said to be 30% more effective then todays current batteries. I just thought this was very interesting imagine a car batterie sized battery made like this could probably run 3 cars :) since we all know lead acid batteries are clunky and outta date. Also its too bad that hailstorm project got shutdown was an interesting read.
fiber0pti	Posted - 2006.08.06 07:55:00 - [119] Edited by: fiber0pti on 06/08/2006 07:59:29 Kind of sad to see that the only science people get excited about is designed to kill people =/. Guess its better to spend billions on the millitary than to focus on fixing the many domestic problems we have or to relieve the millions of people who are starving or homeless around the world. This is what you get when your millitary budget is larger than the next 20 nations combined and 6 times bigger than Chinas.
Jon Engel APEX Unlimited Kimotoro Directive	Posted - 2006.08.06 17:57:00 - [120] Nobody starves in America dude. If they where we wouldnt spend that much on our military.
