Rotating Fission Fragment Rocket Engine (RFFRE)

@Samps0n if it is possible, it will be my pleasure to communicate with you in a more frequent and private way (maybe an email or other social media link?)

@Samps0n Honestly speaking, it's my honor to receive and share more knowledge via this community, and it's my pleasure to meet & communicate in a profound, scientific way with you. BTW, rocket engines' performance is hard to modify into correct data (with original parts in the game). I would like to apologize that I cannot get reliable resources and provide scientific data currently, and I'm working on a mod to improve this, and thanks for the link mentioned in your comment 👍

@Oxyrea if your job is to teach about atomic rockets know i blame only you for my serious (as serious as a casual internet cram gets tho I could write a 5pg cited essay on itIntroduction to atomic rockets it’s you. You Piqued my curiosity upon realising the huge differences in size , thrust, and isp in your models. then I believe I overread a chat of yours that mentioned a website that is very satisfying, wikis and 200 authors it’s info that reads like a stereo manuals. I am only 70% sure that I got the site from you. If not will you let me know? It will please me if was able to offer some knowledge back. It’s www.projectrho.com ‘atomic rockets, science to sci-fi’ its a tool for for sci-fi writers,I think. I have only scratched the surface so far. It’s taken more of my digital time than all my other pet projects since I found it.

For the Nuclear Reactor, in this RFFRE
It is well known that the intensity of fission depends on the nuclear cross-section of the fuel and the concentration of neutrons. To ensure sustained thrust, subcritical nuclear fuel is coated in pellets or layers on a disc made of fiber (with multiple layers of fibers to improve performance). On either side of the disk are reactor cores where fuel will get to a critical state and start reacting, and the charged products are tossed out of the disk, guided into the nozzle, and ejected at great speeds by magnetic fields. In order to solve the heat dissipation problem, the rotor plate will go directly into the vacuum after leaving the reactor, so the distance between the two reactors should be as large as possible.
BTW, Am is the nuclear fuel to produce electricity, and Xenon is the working fluids in engines (which have to be distinguished)

@Samps0n
According to your description, I think you are trying to talk about the energy source for a nuclear electric rocket (a reactor produces electricity to power electric ionic engines).
Yes, there are Nuclear Electric rocket concepts powered in this way.
If a fission reactor can reach 30MV+ electricity production, doubled reactors can produce 60Mv. One ionic engine consumes about 7kW in reality, 60Mv will be way more than enough to power 468 ionic engines. But we have to notice that the thrust/mass proportion of ionic engines is relatively small, more ionic engines might not bring improvement in spacecraft's acceleration (or even bring disadvantages), and the price of the ionic engine will raise dramatically at the same time.
And, YES, most of the ionic engine still relies on Xenon.

Yea, I dig it. The sci-fi your creating has no theoretical roadblocks just practical ones and it will take a need for the advances for them to become common. Now between your xml skill and you passion for exotic propulsion makes you a logical choice for a person that I could ask about making a powers source to operate 468 vanilla ion engines . So far 2x reactors can operate them at 24% power. What does this engine run on? Does it require xenon?

@Samps0n BTW, my first purpose in building those engines in the SR2 is to allow more users to learn about nuclear rockets and their backgrounds, rather than making it 100% identical in the paper (also impossible), but I will try my best to make it accurate if I have performance data about this engine.

@Samps0n This work is inaccurate since SR2 has no nuclear reactor yet (except Nuclear Thermal Rocket). I set it unable to control the thrust for aesthetic purposes (though in reality, I think this kind of design does require a fixed rotational speed for reaching the reaction condition and preventing the overheating problem).

This is sweet, so I had a glance at the paper(bookmarked it, ty) but is it in the game or irl that you can’t adjust the throttle. Do the ion thrusters need xenon? It runs without the engine turned on, can you make a reactor with the realistic feel and the 30mw + power output for use in other power plants? Looks like very little tinkering, is that accurate?

@TJSA cool bro

@Oxyea I'm going to use it for my spaceship infinity.

@TJSA nuclear engine is a great way to increase fuel energy density

Wow a fission engine incredible

@Vedhaspace thanks man hgahga

Man totally awesome!
Looks cool

@FelixFan1 thx man

I’m impressed
