I wonder what the Isp of a Coke and Mentos reaction engine would be...

Has anyone tried to rig a de Laval nozzle to the end of a bottle yet? |

Has anyone tried to rig a de Laval nozzle to the end of a bottle yet? That won't work. the exhaust is a -very dense- liquid flowing at subsonic speed, so the most effective nozzle is the plug nozzle. |

why can't we use more exotic fuels for NTRs like thorium or whatever

Reviving this thread -- it probably should be moved to Suggestions. But also: I want to model rocket candy in game, and it goes along with having chocolate as a material. Does anyone have the activation energy, autoignition temperature, and characteristic length handy for any sugar + potassium nitrate? Seriously though, this is a great idea and I'm sad no one mentioned it earlier... Oh man rocket candy... that's bringing back a few great memories... Yeah, I'd like to see that for sure, but isn't it solid fuel? Whatever, I want to put it in now anyways. But more importantly, does anyone know how/if we can access the equations that are used for creating modules, and the limits on size in the module creator? |

But more importantly, does anyone know how/if we can access the equations that are used for creating modules, and the limits on size in the module creator? I'm wondering if rocket candy could be a liquid(at reasonable temperatures) and we could use it as a monopropellant. And for equations that the game uses, not really but the info links have peer-reviewed articles where it probably uses some of their equations. |

Well, sugar doesn't technically melt.
And it decomposes at a temperature less than the oxidizer.

... and you picked the candy thread to ask about Thorium?
I am not convinced you can use it in place of Uranium -- Th-232 is fissionable, but only with high energy neutrons, not thermal ones -- but find some reference and the missing data and go to town?
On the other hand, this topic and this thread makes me want to mod in Uranium in caramel suspension as a nuclear fuel. Maybe in sugar glass. Candy with bits of radioactive sprinkle.
Edit to add: also! Thorium is mostly used to breed U-233, rather than as fuel itself. It's abundance is why U-233 is so much cheaper than U-235 in game, I believe.

Has anyone tried making skin a hull material?
