How does ships turn in space?

Real spaceships rotate via attitude jets or reaction wheels (gyroscopes). But that just changes which way they are pointing, not traveling. To change travel direction they first rotate to point the main engine in the desired direction, then run the main engine for as long as needed. For example to change course by 90 degrees the ship would first rotate 135 degrees of its flight direction, then fire the engine until the new direction was achieved.

For Eve ships the best explanation Ive seen is our ships are not rocket ships, but are propelled by a gravity drive. This drive reacts against the local "fabric of space". The exhaust we see on the ships is just exhaust from the power generator powering the gravity drive, it no more propels your ship than the exhaust pipe on your car propels your car.

A Stasis web slows you relative to the fabric of space. Anchoring fixes your location to the fabric of space.

Super-fluids can be affected by electromagnetic forces in a manner that causes it to become resistive. Our ships drives systems would be constantly emitting such electromagnetic waves, and by tuning those waves, or emitting them in specific directions, we would gain "traction" on the surrounding space thus allowing the ships to turn.

they turn like fish in water

how to fix eve: 1) remove ECM 2) rename dampeners to ECM 3) add new anti-drone ewar for caldari 4) give offgrid boosters ongrid combat value

Interesting thougth, although this means that your warpdrive is actually constantly active.

Incorrect. The reality is that the engines flicker on and off at a very high rate. Reason being, that if you have multiple ships turning space around at the same instant you wind up ripping space apart. Imagine if a vinyl record[1] had two holes in it and two turntables[1] were trying to spin the record at the same time in different directions.

Instead, every ship interleaves their flickering so that one and only one ship in the entire universe has its engines in the on state at any time.

Incidentally, as the number of ships in close proximity increases, the ships begin to experience the perceptual phenomena known as "lag" (aka the "slideshow" effect) as each ship's flicker rate is reduced.


[1] For our younger viewers, a vinyl record is much like a CD but is much bigger and, instead of a beam of light, an actual needle is used to 'read' the data from it. A turntable is simply a motor that spins the disk in a manner similar to a CD (but at a much slower speed.) http://en.wikipedia.org/wiki/Gramophone_record

I do belive minmatar is using somekind of solarwind technology when it comes to turning.

The best answer i found is:

The problem is that you think those things on the back of your ship are your primitive Earthling stone-age rocket thrusters. No, sunshine, this is the 24th millenium or somthing, they're actually protowarp interspace exhaust particle arrays.

The exhausts don't provide newtonian thrust, they're just where the ship expels charged warp particles generated through the ship's warp engine based sublight propulsion system. Upon leaving the ship these particles decay into normal space and manifest in normal space as light emitting ghost particles. Notice how they hang in space relative to the warp reference of the system instead of floating around like normal particles would in newtonian space, and they aren't affected by other ships passing through them.

This warp engine based method of sublight propulsion is also why your ship doesn't follow newtonian rules of motion while in space, it is anchored to the system's warp reference plane.

Starship engineers put the exhausts on the backs of ships because they look cool there. The only ship that didn't have them all pointing backwards was the old griffin ship hull, and it looked silly with them sticking out to the side.

When I turn my battleships, I like to imagine all the crew suddenly toppling into the sides.

Your all wrong - Its called a Quantum Accelerator Rudder drive which leverage off Dark Matter. As you all know (having qualified for your Pilots License) that this is the stuff that holds the universe together. The Quantum Accelerator Rudder therefore will turn the ship by converting the Quantum Inertia to Kinetic Energy.

theres more than 1 engine, by adjusting the thrusting on 1 engine more than another the ship will rotate... the warp drive engine makes the space around the ship act like a "liquid"... this is also why ships get bumped when they fly into eachother instead of exploding because of the collition.

The warp drive is the reason for why our ships also doesn't keep accelerating even with the massive engines constantly running, as the warp drive creates a drag around the ship... (which is also why the ship can stop simply by stopping the engines, it would continue at same speed if it wasn't for this)

hope that information helped
