Sfs Nuke Blueprint -
| Mistake | Fix | |---------|-----| | Using nuke stage during ascent | Only fire in vacuum | | Too few fuel tanks | Nuke needs lots of fuel to be useful | | Overheating (mods only) | Add radiators | | Forgetting decoupler between nuke stage and booster | Add separator |
Understanding the real science enhances your build. Nuclear thermal rockets work by passing liquid hydrogen through a reactor core, heating it to 2,500°C, then expanding it through a nozzle. In SFS, your Valiant engines simulate this, albeit with lower performance. Kinetic impactors are real – NASA’s DART mission successfully changed an asteroid’s orbit by slamming into it. Your SFS nuke blueprint is essentially a DART on steroids. sfs nuke blueprint
Flight profile: Activate the Valiants only in vacuum. Their specific impulse (Isp) of 350s is the closest you’ll get to real NTRs (900s in reality). For modded SFS, the SFS Nuclear Pack mod adds true NTRs with Isp > 800s. | Mistake | Fix | |---------|-----| | Using
