An Experimental Custodes Grav-Rhino, from the Horus Heresy 'Collected Visions' Art book.
Does anyone else have any examples of one-off weird 40k technology?

Everything an Ork ever made

But from what I understand from the Lexicanum, they explain that most Artificer Armour in Chapter Armories are basically modified (But not standard modifications) standard PA.

Also I definitely want that rhino.

What are the boosters for if its grav driven?

Seems something my regiment (the 91st Experimental) would field. i Got a Russ sprue coming and gonan make into a hover tank (not sure of varient though). i can't remember where exactly (but im sure it was on Dakka) that there was mention of a Leman Russ that had Grav Systems. now with that Grav Rhino picture i have a design to go off of. no less outfit a broken and torn to shreds model Patton tank hull (whos ENTIRE track assembly was damaged beyond repair by its prevous owner i had to remove it all) to be a Malcador of some kind with Grav tech.

To complement the cool spoiler on the back, lol.

The only other thing i've found to that grav rhino. is grav bikes used by the same guys who made the Rhino, the Custodes. onyl that the Grav Bike are not experimental and used alot (if only by them)

Anti gravity generators only just oppose the gravitational effects of opposing surfaces like a planet, you still need propulsion devices for movement, this is seen on Tau and Eldar vessels.

Well, it isn't exactly a one-off, but it is fairly uncommon, and awesome.

Isn't that because they're crafted by Tech-Marines?

But if something is propelled magnetically, it doesnt need propulsion devices. It just needs activating and deactivating different parts of the magnets.

Same way magnetic train works.

1. Something can only be propelled magnetically if it is on a specially designed track, that also contains magnets
2. The same applies to levitating. You can't just throw magnets on something and expect it to levitate.
3. If you somehow had a magic anti-gravity generator, you would still need a way to move yourself in a direction that is not "opposite of gravity"

What you say doesnt make full sense.

We already assume the grav rhino in the picture is not operating on track.
Which means its operating within a mag field.
if something is operating within a mag field, than the whole world, 3 dimension works as a track.

Hence you dont need a thruster.
( its basically how people used to think UFO works, remember? )

I don't get why you are assuming that the grav-rhino is levitated by magnets.

Magnetic fields are not some ever-present grid that you can tap into and float around.

The rhino is kept floating using a gravity-repulsion system, similar to Eldar tech, but it still needs to be pushed in one direction or another, hence the boosters.
The grav-repulsors don't propel it, they merely keep it above ground level.

ph34r wrote:I don't get why you are assuming that the grav-rhino is levitated by magnets.

I didnt say its levitated by magnets. Its by manipulating the field in relativity to the rhino.

ph34r wrote:Magnetic fields are not some ever-present grid that you can tap into and float around.

Why aren't they? They are ever present from the polars down to every planet's core.

By all means I don't know how Grav tank in the story works, Im just basing it with real science.

In other words who ever wrote it didnt research how it works?

Oh I get it, like the Jetsons cartoon

This is where you are making your mistake. Real Science has no place in Science Fiction. The repulsor lift of this, and other anti-grav vehicles, provides the vehicle a "cushion" below it that keeps it off the ground, relative to the plane of the planet. In order to move forward, or side to side, or even backwards, it will require some other motivating device, such as a thruster, to do so.

This is because a planet's gravity well is assumed to pull one downward/inward towards the core, the center of the well. The grav-pad is always laying flat against this pull, and will need something else to push it forward.

Im fine with using that as bases for now. Then assuming we are using that model, what would happen when the grav-pad suddenly is imbalanced?
e.g the distributing of what was keeping it "flat and afloat" suddenly become powered less in some area, and more in other areas?

For the same reason that Land Speeders, Eldar tanks, and Tau tanks have thrusters. The anti-grav drive under them is only to keep them afloat. If the superscience they use had a firm basis, they would also be nearly frictionless as they float there, but still need something to provide thrust.

I'm assuming these vehicles would probably use a controlled version of that effect to bank and turn, combined with uneven thrust in the needed direction from the engines in back.

K... it really is like the jetsons then -_-

Im suddenly dissapointed in 40k

If you like those amazing tech things, check out Gravitational Beam Emitter (GBE)
where warhammer "borrowed" from.

It's not an issue of the author not doing his homework.

Science just doesn't work that way. You don't "manipulate the magnetic field" and float somehow. Grav tanks work by future magic technology. If we knew how they worked in real life, we would have grav tanks.

Interesting to watch

Yep, the LHC is pretty awesome. I know a decent amount about that kind of stuff. Luckily as you can see the world did not end when it was turned on like that video feared 4 years ago

If they can manipulate the magnetic fields to propel and split atoms and electrons,
there is no reason to not expand it further and apply it to gravity engines.

well someday I guess

It crashes and, because this is a hyper-violent action game, probably catches fire and/or explodes.

Actually i was thinking more along the line of this
Imagine the "wave action" as magnet pulsing through the field, the balance and imbalance creates movement xD

Getting back to the original question. The Grey Knights posses alot of experimental tech. The teleporter packs used by Interceptor Squads are suppose to be very advanced and the Grey Knight have alot more conversion beamers than most Space Marine Chapters, meaning greater access to experimental/unconventional tech.

Basic physics here:

F = -qv x B

B is magnetic field, q is charge of electron, v is velocity of electron.

To get a force to lift one human off the ground in earth you need approximately 800N for an 80Kg Person. To get 800 Newtons of force out of "mag lev" engines in the earths magnetic field the velocity of electrons flowing through a conducting material is just stupidly large. I CBF doing the calcs but Id say it would be close to the speed of light. If such a speeds could be reached it might work for about a microsecond before the whole thing melts. But of course the powers of the warp make everything legit. Oh and thats just for one person let alone a 1000ton rhino full of power armor.

Yes, and that Rhino definitely isn't suspended in a magnetic field anyway, it's using hand-wavium-powered gravitic repulsors or some-such. Most planets don't even HAVE magnetic fields, so that whole idea is just right out, impossible physics aside.

LunaHound - don't be disappointed. This is how it has to work, and here's why:

Assuming you have some magic gravitic repulsors, you still can't propel yourself forward or sideways by changing the strength of the repulsors on different parts of your vehicle. You're assuming this would work like a helicopter, where you change the distribution of lift on the rotor disk, and the angle of the rotor disk, to push yourself in whichever direction you want. This only works because air is all around you, and you can generate a force by pushing against it in any direction.

Gravity is a vector pointing straight to the center of mass of the planet. Assuming you can work against the effects of gravity using your magic repulsor, you can generate a force in one direction: up. Whatever angle your repulsor is at, there is no horizontal component of gravity to work against (unlike the air a helicopter moves through). So you can't generate any thrust for forward or lateral travel.

Even if you vary the strength of the repulsors along the length or width of your vehicle, there is no horizontal component to the force. All you end up doing is moving different parts of your vehicle up or down relative to one another, i.e. pitching or banking. Eventually you'd just flip yourself over, but you wouldn't go anywhere.

So it's not Jetsons. Surprisingly for 40k, it actually makes perfect sense.

Quickest way to start an argument on Dakka and get off topic : Apply basic physics to 40K. hahaha

Well it was a justified question with an answer that GW have most likely thought about seeing as every anti grav vehicle has additional thrusters to allow for propulsion.

As to the OP experimental technology usually gets filtered to specific groups such as the Grey Knights, certain chapters linked with the Mechanicus, and the Mechanicus itself. However alot of ancient/crusade era technology exists throught the IoM and none IoM human worlds, ranging from crusade era dreadnaughts, the hoverbike of the Dark Angels, to world computers that can control human populations.
