sumoftwosins Posted January 5, 2009 Share Posted January 5, 2009 They have about as much in common with a Gauss gun as my cat has with the chinese dragons. Regardless of the validity of this statement.... it is funner than hell. +10 Link to comment Share on other sites More sharing options...
furtim Posted January 5, 2009 Share Posted January 5, 2009 Here's a vid of a real US Navy rail gun test fire. Draw your own conclusions. It does appear, however, that it's built up enough velocity in the projectile to become explosive from the tremendous kinetic energy alone. Well, that's a railgun. Railguns work by running a current directly through the projectile being accelerated, so in the barrel there will be some electrical arcing. (This is a major obstacle to deployment of practical railgun weapons. Energy generation is not a problem with a nuclear battleship, and obviously the video shows that velocity is not a problem either. However, the arcing tends to foul up the barrel after a very small number of shots.) You'll also notice that, in flight, the projectile has a visible shockwave but not any kind of light trail. There's a brief puff of smoke as it leaves the barrel and a big plume when compressive heating causes an explosion at the terminal end, but nothing during the ballistic phase of the projectile's flight. At that point, it's no different from a normal bullet. An effectively weaponised coilgun would look about the same, except there wouldn't be any arcing in the barrel. There could be a smoke puff from compressive heating of air or, more likely, Prandtl-Glauert singularity, though. Still nothing that produces a laser-like beam. Also, to the guy who asked, Eraser was a terrible movie starring the Governator that revolved around the development of a man-portable railgun weapon.

There could be a smoke puff from compressive heating of air or, more likely, Prandtl-Glauert singularity, though. Still nothing that produces a laser-like beam. That is a round going at Mach 8, and it acctually igniting the air it travels through lobbing a round at say a Quarter the speed of lightspeed (~Mach 22000) whos to say that the round doesn't Out run the ignited atmosphere it creates? the round would be traveling so fast that the chemical reaction caused by the friction to create heat would happen Behind the bullet rather than infront of it. thus creating a 'trail' of ignited air. now if you where to fire at something thats 1 light second away, then yes the round would not look like a laser at all, it would look like a bullet with a very long trail following it... however since our precieved man to man engagements are measured in in 50-500 feet, it Would be 'Instant' and create a Laser looking trail between the barrel and the target.

r4y30n Posted January 6, 2009 Share Posted January 6, 2009 I dont know much about the specifics of magnets, but the laser effect, could be some discharged electricity attracted to the slug, or more feasibly the air the projectile is passing through turning into plasma (not sure thats possible, but I was told thats like the 4th phase, but I've also heard that plasma is only usedto describe superheated, uranion or deuterium or somehshit like that) via the intense friction caused by something fireing that fast, or more mundanly the air is ignited, once again by intense friction, and the funky colours could be explained by the material of the slug being used up in the combustion coloring it... Actually, as current passes from one rail through the slug to the other it can arc, causing a colorful flash of plasma (just like a lightning bolt, but contained within the gun). Plasma is just ionized gas; heat up any element hot enough and it will turn to plasma (big stars can have plasma composed of carbon, oxygen, neon and silicon). Friction heat (as was previously mentioned) is what makes all the smoke, and what makes the projectile look like a fireball in some shots. the thing is people think that they are shooting bullets which are compherable to similar sized weapons... however, this is acctually the opposit, the Gauss rifle would be shooting extreamly small rounds comperatively at higher speeds. so while you have a .50 caliber round the Gauss rifle of similar size would be shooting around about the size of a Pin needle tip... shooting a smaller round faster = same amount of energy as shooting a larger round slower. Not quite. A round the size of a needle wouldn't maintain its velocity very long due to the lack of mass, so there is a realistic minimum size for such a weapon. Furthermore, there isn't much point in building such weapons to be comparable to conventional weapons, the whole idea is to be superior to what we currently have. The projectiles in those test shots were comparable in bore to the 5 inch naval guns they're supposed to replace. In fact, I wouldn't be surprised if the production slugs weigh as much as an entire 5 inch round (projectile, case and powder). Oh, and in response to Pyro Paul, the only way anyone would get a round to go any meaningful fraction of lightspeed, you would have to use infinitesimally small slugs, like say, a string of atoms as used in Nikola Tesla's charged particle cannon concept. By the way, has anyone seen the gauss rifle that Bethesda is throwing in Operation: Anchorage? http://media.ignimgs.com/media/thumb/267/2676305/fallout-3-20081210103225985_thumb_ign.jpg Here's a link to the fullsize pic: Link Link to comment Share on other sites More sharing options...
Strofkocz Posted January 6, 2009 Share Posted January 6, 2009 indeed I have, I hope they make it accessable in the main game, and not just in the sim. Link to comment Share on other sites More sharing options...
skojolt Posted January 6, 2009 Share Posted January 6, 2009 Has anyone made an fo2 style gauss yet? I want to create a nice one with lots of rippling tracer effects, and a good rusty texture to fit in with the fo3 theme. Link to comment Share on other sites More sharing options...
RyuaNesha Posted January 29, 2009 Author Share Posted January 29, 2009 Lol, I am in the middle of playing operation anchorage. I then received a certain weapon. A Gauss rifle. Anyone think that Beth saw some of these mods/read this thread and decided to make one for fallout3 themselves? Link to comment Share on other sites More sharing options...
xelnagahomie Posted January 30, 2009 Share Posted January 30, 2009 SPOILERS AHEAD! Ha HA! Gauss gun is just one of the phat lewts you're able to take as a reward for completing Operation: Anchorage. It's a fairly powerful (Yet one shot per reload) energy weapon. Fairly nice knockback if you get a critical too. Link to comment Share on other sites More sharing options...
Pyro Paul Posted January 30, 2009 Share Posted January 30, 2009 that doesn't make sense.. gauss weaponry is ballistic, and should be under small arms.even though it looks like it is shooting lasers, it is still shooting solid slugs... for some reason this makes me miss mechwarrior.
