I tried to model our fusion rockets using the NTR module rather than the combustion rocket module, which allows more interesting designs. You can vary the amount of reaction mass fed into the engine, allowing higher acceleration designs without having to create a new chemical reaction. The main downside of this is that power requirements are hard to calculate and direct fusion exhaust is nonexistent.

This should be a workable representation of metastable helium. I had to make quite a few assumptions, so most of the data is from liquid or solid helium. Additionally, the density is the theoretical density from the first source. The highest density I could find that has been achieved in a lab was 6.644518272425249*10 -11 kg/m 3.

You will probably have to use a magnetic nozzle (or at least a crude representation of one) with this engine, as it reaches 70,000+ k. To use it in a vaguely realistic way, you should match the thrust power of your engine with reactor power.

Also, DD fusion reaction appears in my infolinks but not in my drop down list of selectable reactions. I can't work out why. Any ideas? It may be modeled as an explosive reaction rather than a rocket combustion reaction. Does the reaction have a characteristic length?

and an overestimation of the effectiveness of regenerative cooling. Wrong, wrong, wrong, you're wrong. Try building a Raptor engine in game with the same specifications and materials used IRL. It doesn't work; the game massively underestimates the effectiveness of regenerative cooling if anything. Perhaps in normal engines, but not in the strange edge case of "fusion" engines, which was what I was referring to. 1 kg/s of deuterium-tritium mixture is able to cool a tiny engine bathed in terawatts of heat.

Something to look into would be isotopically pure C 12 diamond, which seems to have ~50% higher thermal conductivity than the 98.9%C 12- 1.1%C 13 mixture found in common diamond. I’m not really sure how the game calculates yield strength and if we can somehow simulate compound gun barrels or engine nozzles with that mechanic. How does our version of graphene somehow withstand fusion temperatures? The game does not calculate yield strength, it is a value that must be inputted for each material. We already have composite barrels, and I doubt that composite nozzles would be useful. Our version of graphene should not withstand fusion temperatures; it's a limitation of the game and an overestimation of the effectiveness of regenerative cooling.

All these bots seem to post in either Russian or Vietnamese. I wonder why they don't just auto-translate it into English.

Lonsdaleite seems to be stronger than cubic diamond's weaker plane and weaker than its strong plane. I don't know how useful that would be, as in-game we apparently have atomically perfect manufacturing which would allow us to orient the crystals as needed.

this bug can affect missiles too. When a swarm detaches their tanks they all go into a frenzy trying to doge 800 objects at once and burn their fuel instantly.

Oh baby, I got it working. The missile atop its drone firing stage: imgur.com/LGafxQ6Payload inside that stupid looking blast launcher: imgur.com/z3F5GRzJust a 10 kg tungsten slug as a warhead. imgur.com/QQNoPo6About 7 kps inbound result 'enemies are no longer a threat'. imgur.com/4Woeu6wThe walls of the single-shot blast launcher I ended up using UHMWPE fiber and just 1 gram of Nitro Glycerin. Results in not too much extra tonnage, but it would look alot sexier with my kinetic kill missile on top of it instead of a silly looking big box. If you make an album with those images it will be easier to see.

It only gains .6 kg if it is set to cover the entire missile, so I don't think it's bugged. It's still a perfectly functional weapon either way. I know for a fact that the previous version allowed for grossly underweight partial armor. I had warships coated with half a meter of U-235 dioxide just because it cost next to nothing. See here for roughly 1500 m³, or 50 Gc worth of uranium on a ship costing 2.7 Mc: dl.dropbox.com/s/y2bb4xlh79bzmot/20170802000004_1.jpg?dl=0I can't be certain but I'm guessing the game computes armor volume somehow discretized, possibly using the mean of partial armor segment sizes regardless of the actual size. You can see how the armor cost stays flat from around 75% to 50%, but gets halved when you go to 76% of armor start. Also, it's a bit of a stretch to claim that losing a few km/s of dv and doubling the cost of your craft is "only" .6 kg increase. If partial armor is allowed, it will obviously be the optimal choice as it allows you to cut off 5-10% of your mass for free. I am well aware that high start % partial armor is bugged. After some math my missile probably has ~100 grams of magic massless armor. Regardless, partial armor is allowed. If it is banned, most of the submitted designs will be disqualified.

With the reduced mass of the Remote control, I was able to create an incredibly light and cheap missile, the Quill KKV. It can kill a gunship in one hit and can easily withstand its laser. Further improvements would likely require limiting editing (higher aspect ratio for the RC and smaller tanks for less mass). If it was possible to reduce the wet mass to ~4.9 kg you would get ~26% less mass in exchange for ~12.6% less Delta-V. Partial armor leads to some questionably light armor layouts so I'm not sure if that should be allowed. Well, at least it's cheap! It only gains .6 kg if it is set to cover the entire missile, so I don't think it's bugged. It's still a perfectly functional weapon either way.
