We have most of the data already. Any literature evidence on how the reaction goes? Yeah that's the problem, most of these reactions don't have data on them, or they're hidden behind peer-reviewed paywalls. Try emailing a bunch of chemistry/Space science lecturers at some universities. They may be happy answering questions... |

I have a thing with my university's library that lets me into most databases, but I feel like eventually I'll get an email: |

Added a post to the Cubane thread asking for help with the reaction with Fluorine, in case anyone can assist.

David367th I didn't expect increasing the girth, er bore radius, of a conventional gun would allow building something that weigh less than something with smaller bore radius. I wonder how lasers can keep the spot on them accurately enough for them to die though... I need to get my hands into nukes and try them against lasers, so far I've been using a drone with 3m of Tantalum Hafnium Carbide (didn't even run optimization tests, it's prolly not the best) at the front to cover every subsystem and has worked against 19 x 8GW UV lasers... Although I am bugging the engine to do this (armor that exists but isn't calculated into physics or price, or done so at a very reduced rate) I didn't realize how bad it was lol, I increased the % for that armor and the cost went from 2MC to 1.4GC and the mass from 145t to 8.21kt It's a cheaty strategy, time to come up with a noncheaty one

I wonder how lasers can keep the spot on them accurately enough for them to die though...[...] With firearms it's more of a sweet spot of all the variables where the barrel doesn't melt or shatter from pressure. And I've found lasers have no trouble melting the front off of them in a split second. |

David367th, I'm trying out your cannon, you can drop the thickness to 1mm if you use UHMWPE (how does anyone remember this word), increase the explosive mass to 2.50g and 240um, as well as reducing the copper momentum wheels to 5kRPM for a total of 10W Momentum Wheels power and an increase of muzzle velocity to 2.45km/s as well as a weight decrease to 663g. tldr; made it better, here haz canon:

Is the 8 second cooldown time OK?

Is the 8 second cooldown time OK? No thats why I didn't use UHMWPE, they do not cool down, and they eventually take 1 shot every 8 seconds. Forgot to tell you that tessfield they were originally UHMWPE but I had to change them because plastic no like heat. Good edit anyway tess. If you're going to do testing you should see that the gun shoots full rate of fire for a minute or so then stops entirely and you'll see a message on the gun's UI saying that it's overheated and to make sure you got radiators extended. Yet you can't rig a radiator to a gun. qswitched M1917 Watercooled gun pls. Looks like Boron is actually good enough to withstand the heat and pressure at 1mm. Should've seen that. |

I ended up using Boron, since 'eventually' means after 2 shots, at least on the way I designed the gun. @qswitched quick bug report/optimization, make the shooting animation in the design screen take into account cooldown time Here's the gun:  |

First a missile of dubious effectiveness, but you could always field a few... million.  I tried making a good conventional cannon, but it seems at those sizes they're not really doable. Unintuitively, a larger calibre and thinner barrel stresses the gun less. Seems you realised already, well, here's my design anyway. Size of the gun below by itself is 2.28x2.28x35.1  |

It almost triples the weight of the cartridge, and when my drone's weight is half bullets, it makes a big difference. When we're conscious of mass here I don't know if the extra 0.55km/s is worth the extra weight. Then again I guess the 200g lost from the barrel is 50 bullets. We'll have to see. |

Someone said something about a laser drone cold war, and let me just make my opening move with my totally top secret mini solar lance. |

They must have used potions and magic on their drones! I don't know either. |
