This is just a fun thing I thought up while doing some designing. The challenge is to create the cheapest and lightest ship possible that is still crewed. Said ship must also have 4km/s of delta-v to allow for reasonable maneuverability. My own design, to start things off:  Have at it! |

Is modding allowed? If yes, here's my candidate. Useful when you need a quick trip to the moon but don't want to wait for a passing liner.  |

Yeah, that mod removes crew limitation, so it's cheating. Really insane cheating plus impossible-to-beat one at that.

Civilians without access to trained nuclear reactor technicians sometimes choose to use RTG-powered ships. This particular example is used by those who want to travel light and stay far from the most civilised ports. It is using hideously radioactive Cobalt-60 RTGs powering a pair of light resistojets and is using hydrogen deuteride as propellant due to its cheapness and good Isp.  The unusual length of the craft is due to the 200m space, helping decrease the radiations to the crew module, but it still needs several 1m-thick blocks of lithium-6 to stop the many remaining kilo-Sievert. The tapered lithium radiators are shaped this way to avoid back-scattering radiation, which would otherwise be reflected to the crew module. The skin is an extremely thin graphite aerogel film, to avoid showing the ugly plumbing between the tank and the resistojets. The crew module has two redundant radiators, because even for the kind of insane cheapskates using this model, they aren't expensive enough to justify the kind of risk a crew radiator failure represents. There has been at least one documented case of such a craft used in an attempted terrorist act against a space station, namely by putting it in automated mode and trying to fool traffic control into letting them dock. However it is still unclear whether it wasn't merely a misunderstanding, an accident, a false flag operation or just someone being really, really stupid about it, as it was very violently dismantled by nearby patrol drones. Also we shouldn't have to say that, but never, ever EVA outside the radiation shield shadow. Not only will you be fried, but the backscatter may irradiate everyone else still in the shadow. Remember, Darwin works only if you are only killing yourself.

How would it fare if you switched to curium RTGs? |

Post by thorneel on Sept 2, 2018 19:26:25 GMT
Curium avoids those pesky MW of radiation, but an equivalent Curium RTG is also several times more expensive than the entire ship. It would make for a good civilian RTG standard, though. I could even use that for my new Prosperous campaign mission lol I'm curious to see what you will do with it! (All ships I post here are free to use in custom mission/campaign, by the way) |

Cobalt-60 RTGs The unusual length of the craft is due to the 200m space, helping decrease the radiations to the crew module, but it still needs several 1m-thick blocks of lithium-6 to stop the many remaining kilo-Sieverts. Lithium-6 is no more effective than other kinds of mass shielding against gamma (which is what cobalt-60 radiates). You'd do cheaper with the same mass of potassium or selenium, or just more distance (or propellant tanks in the way).
Li-6 is fantastic against fast neutrons, but only that.

Yeah, I had completely forgot that. This pile of lithium can be replaced by 4 m of potassium for much cheaper, dropping the mass to 105 t and the price to 556 kc For reference, with 200m separation plus a hydrogen deuteride fuel tank between the RTGs and the crew module, it recieves 1.22 MS (and no, this is not a lowercase m) Unlicenced civilian craft.txt (3.47 KB)
