Just imagine this wild, badass merc sitting down, telling couples how to "keep it fresh". XD

For some reason I can imagine that...

That's what his first job was, but then he got the itch for adventure, picked up his gun, and headed to space. :p

That would actually be a pretty interesting conversation topic... I don't know, but I just might have that as "canon". Soon after escaping GRACE, Ethan needed a job, took a test, tried out the job for a while, but got bored/got attacked by GRACE.

Hey, even RP characters live mundane lives, at least for a while. :p


Also Cucoo, this might be a crazy and complicated question, but what do you know about railgun physics? :p

As of my latest physics course, lots.
Pretty much the course is electricity and magnetism so... Yeah.

Well, I have been trying to find out how powerful the railgun on Ethan's ship should be in EG, and experimented with some velocity, mass, and force equations to find how fast and damaging the projectile would be if in a space battle. I have that part worked out, but my problem is finding out how much power would be required for the amount of force generated. I have looked through the math behind the railguns and have been slowly piecing together what the equations mean, but I still can't figure out all the equations and chain them all into one process, the firing of the gun.

At best, I have only found the very basics (right-hand rule) and some of the variables within the equations, but all the other sources I have found require you to have a greater understanding of physics/variables, greater than what I know.

It might be much, but do you think you could explain what some of the variables mean? I may not have advanced knowledge in physics, but I can catch on fast.

I can do that, just list off what you do have and some dimensions of the gun and projectile and I can figure out the rest.

Ok, just give me at most an hour, and I should have the dimensions. Doesn't help that I didn't build the railgun yet, due to not wanting to proceed without the math first. :p

@Cucoo

Might take a tad bit longer. Had to take care of partied out dad.

Also, just to be sure, how large do you think the distance between two ships would be if they were in a battle? I was thinking that they would be thousands to tens of thousands of kilometers away, so I adjusted the velocity accordingly (1,000,000 m/s; 1,000 km/s).

Does that sound right to you?

Perhaps...
Though my thought process is current day when it comes to combat.
All I know is that for modern day fighters, "maximum" gun range is within a km... and thats if the pilot has good aim even with the computer guidance.
And I'm going to seem like I'm using this as an excuse but remember: the only thing I would get nit picky on is Venturian tech. What Ethan has and is used to could be different and anything you set it as.

Ahh, ok. I tend to forget that... --;

Anyway, here's all that I have. It's a lot, so hang in there.

First, I'll give the dimensions because it won't take as long. I just need to tell you that I went into the ship and quickly got some measurements, so if anything needs to be changed, it could be. Also, I was playing around with the idea that the railgun could turn its rails and could be at a vertical or horizontal position, horizontal being the widest. Also, would multiple rails affect the power and effects on the rails?

Length of rails: 28m
Distance between rail cores: 9m (vert mode); 15m (horiz mode)
Width of rails: 6m

Bullet length: 9m (vert); 15m (horiz)
Bullet width: 3m (vert); 9m (horiz)

@Cucoo

And here's the second post.

This one has the velocities, masses, and force of the bullets. Due to the ship storing mass as digital information, it can generate bullets of varying mass ranging from 1 kg, to 1,000,000 kg.

For future reference, the standard/constant firing velocity for the bullets are 1,000,000 m/s. The mass of the bullets are in the titles, and the force will be listed below the mass.
