DemonxSoo. . . . This is all Greek to me jajaja
Really???? I thought I did a good job of simplifying it all.

Bio
I'm an adult (most of the time) so I enjoy mature content and good stories. Most of the time you'll find me in some Sci Fi thing or another but I do sometimes end up in fantasy roleplays and ,in very rare occasions, slice of life stuff. I've dabbled in other sections of the GUild over the years but Casual Sci Fi seems to be my comfort zone. I'm probably the least intimidating person you'll ever meet and I'm always open to suggestions. I look forward to making some great stories with you all!

Meanwhile, what is everyone else up to? It's been pretty quiet in this thread.
"Can you believe he called my launch bumpy?! Millions o' pounds o' bloody thrust behind you, ought not be surprised it shakes a bit!" Valerie wasn't really paying attention to the monitor. "I'm bringing the Low Energy Nuclear Reactor online in a moment, Jack." She continued through the process as the ship came to life she spoke to herself. "Initialize fuel... preheat the core... time to wake up deary... Reactor is online, switching to main system bus... we're now generating our own power... I'll start getting major systems online now..." She didn't really have to do any of that on her own but she always felt like she would get lazy if she always let the automated start up and shut down sequence run. "Bringing the visual monitoring system online... starting up the VASIMR engines... ignition is good... No problems here. All systems are good to go, Jack"
MOAR SCIENCE!!!
VASIMR stands for VAriable Specific Impulse Magnetoplasma Rocket! It is comprised of several different components. First and foremost is the fuel injection system which, just like it sounds, injects fuel into the system. The fuel injection system is connected to a quartz tube which carries the fuel (Hydrogen or Helium) through the engine until it passes though a coil called a Helicon Antenna which strips the Hydrogen/Helium atoms of electrons so they become ionized atoms.
At this point the ionized gas has left the quartz tube and is contained by an electromagnetic field produced by several superconducting magnetic coils that form a cylindrical barrier for the ionized gas to pass through. That's the 'Magneto' part of Magnetoplasma but there still isn't any plasma!
Plasma exists as super heated gas and is most notably found in fusion reactions (like inside of a star). In order for the ionized gas to become plasma it has to become SUPER heated. To do that you need the last component of the VASIMR engine. The ICRH Antenna, which I honestly don't even fully understand how it works, heats the ionized gas into plasma at many millions of degrees Kelvin.
As we all know, a gas will always try to expand to fill it's container and the same is true for plasma, so as the newly formed plasma tries it's best to expand it starts to put itself under enormous pressure. Remember the Magnetic field that keeps all the gas and plasma in one place? It has an opening at the rear of the engine. That means that all the force of the super heated plasma will escape through that opening and burst out of the engine propelling the spacecraft forward.
The amount of thrust generated through this method is almost entirely dependant on the temperature at which the plasma is heated. Hotter plasma has more energy and more energy equals more thrust. Conversely, cooler plasma has less energy and therfore less thrust. So the way that a VASIMR engine varies it's throttle is by adjusting the intensity of the ICRH Antenna which heats the plasma.

I concur, Dr. Now how do we construct the fuel pumps or what program should be the drive for regulating the fuel ratio into the pumps? *Tries to sound smart* Haha. Sorry for being quite guys! Busy weekened!~ Awesome posts though. ^^ I'll have to gather up my wits and see who's left in the posting order here. ^.-
LET'S TALK SCIENCE (because I accidently brought it up and it's cool stuff)
Actually, by adjusting the flow I don't mean that there will be any more or less gas being pushed through the system. The propellant is actually injected into the engine at the same rate regardless of the amount of thrust produced by the engine. That doesn't make much sense right? Obviously the more fuel you pump into an engine that faster it goes! In this case that's not true.
"I'm detatchin' the launch carrier clamps now. A soft thud could be heard reverberating through the hull plating. We're free of that god awful antiquated rocket now. It should make a nice big splash down below. Once we're clear I can start powering up the reactor." Just moments later they were clear of the launch carrier which now slowly descended back down to Earth. Awrite, switching from internal batteries to primary power bus... A few of the running lights around the ship flickered as power fluctuated for a moment. "...Secondary bus is active...Coolant pumps one and two nominal...Core temperature nominal...Fuel tanks one and two are good to go...I'm bringing up external communications now so we should be able to get in touch with mission control. I'll get our main systems online while you're at it."
Boyo...
I think I've also reavealed my secret identity as a science geek :P
"What're you on about, Boyo? That was a textbook launch manuever." The launch itself was fairly aggressive but not anything out of the ordinary. Just as soon as she cut the engines for the first burn her crewman got out of his seat and turned on the artificial gravity. "Turn that off you pillock!" Val reached for the Anti-Gravity controls and set it to shut down again. "No gravity 'till we finish the ascent. That's all we need is a fault in the primary bus before we even turn on the bloody reactor." There was technically no restriction for anti-gravity but they were still attached to the launch carriage which meant they were using old and new tech on the same power grid so it was difficult to predict how they would interact.
Just ignore that last post.... wrong thread.
