Is there nothing for He-3 He-3 fusion? No, I only gave data for DT, pB11, DD, DHe³ and 4p to The AstronomerThanks. Is there a way to calculate fusion products? He-3 He-3 is differently performative to the other alternatives that I rather thought it might be advantageous to study. |

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?

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. Material Shielded Superconducting Magnetic Nozzle

Nice work. I just tried it out, and unfortunately with the necessary reactor mass it seems to occupy an awkward middle ground between MPDs and high-thrust engines. There doesn't seem to be much it can do that a NTR/resistojet and MPD combo can't do better, beyond a compactness and possibly efficient maneuvering in a deep gravity well. It's honestly far less cheaty in practice than it feels like it ought to be.

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.

And, as a nice side effect, no more touchy fusile monoprops. |
