I gonna dive into this because why not im bored. Though you dont have to take into account what I say, do whatever you want.
The first thing of using a neutron beam to make nuclear pasta is quite absurd since nuclear pasta needs the ridiculous pressure found in a neutron star to exist stably, without that pressure the neutrons will rupture outwards into a more normal arrangement. The nuclear pasta also needs the huge pressure in a neutron star for the neutrons to not beta decay. When a neutron is outside an atom nucleus, it will beta decay into a proton, electron, and an antineutrino at a half-life of about 10 minutes. But in dense nuclear pasta, the energy of the particles is so high that beta decay cant happen (its due to some weird and arbitrary seeming principles that I barely understand.) Also compressing matter into a black hole really can only be done with the pressure of a star's center, and thats really only possible with a star or a star-sized object.
There's actually a way to make a black hole much more practically, theres a theoretical type of black hole called a Kugelblitz black hole. Its a black hole thats made from photons, instead of particles with mass. These types of black holes have already been theorized as a potential spacecraft propulsion method. The idea of using a black hole to create negative energy is just non-scientific technobabble, so I cant comment on the idea further.
I found this paper on achieving a warp bubble without negative energy. I think this paper takes advantage of the 11-dimensional spacetime predicted by String Theory to achieve a warp bubble with only positive energy, though Im not even gonna start pretending like I understand any part of the paper at all. Im sure with more digging it would be possible to find more papers on this topic.
SFS2 will most likely be a more casual game than Juno. It would probably only have one fuel type for all engines and so far it looks like there'll only be solar panels for power generation. SFS2 doesn't really seem to be a competitor with Juno in the same way that Juno isn't a competitor to KSP, the levels of realism and depth are different between these games.
@heitorM you can edit the orbit on computer by editing the support file.
for instance:
in File Explorer go to
C:\Users\YOUR COMPUTER USER NAME\AppData\LocalLow\Jundroo\SimpleRockets 2\UserData\CelestialDatabase\PlanetarySystems
find the XML file of the system you want to edit, then open the file with Word Pad. ill show a bunch of information.
Just find the planet you want to edit. In my case I had to edit the Semi Major Axis of the planet. after you made the change, press save and exit. The file should be changed.
There are some problems with having multiple stars in one "planet system" that is that the planets will always receive light from the base parent sun. All the planets will have a day side facing the system parent star, instead of their own star.
One solution that i've thought about is putting all the orbits of all the stars and planets on the same plane, so that the planets from other systems wont receive light from the north or south poles, and just pretend that the dayside is facing the correct star. (its janky but I don't know of a better way)
Still id love to see this system be complete, its really ambitious.
@urownpersonalgod i ended up just placing ~200 decouplers to get the fuel transfer speeds needed, it was a cursed and sub-optimal way of doing it but it worked.
@ElonCyberTruck I dont know why you'd need to deal with quaternions for it to work. Also, a minor detail I left out is you would need to convert the vectors into their lengths before subtraction. So it would go like
( (craft position vector) + (craft yaw vector) )length - ( (craft position vector) )length.
Idk if you were having any trouble with the equation due to this but I said it anyway.
Dude I had this as a problem too recently. It didnt need to be exact for me, so I was able to roughly solve it with extra vizzy code.
I used [ craft position (vector) + craft yaw axis (vector) ] - craft position (vector).
You can structure some code so if the result is negative then value is added to the bank angle.
@Hyperant Yeah its pretty impresive for an indie game to have its own programing language, but theres some stuff that ive encountered that just seems like Vizzy is throwing a tantrum. One thing that happed is the roll block randomly started jumping between 0 and then the value it should be displaying. I tried to detach other "while (true)" blocks to see what might be causing it, and even detaching 1 random "while" block made it work normal again. Even if you just connected another "while" block to a "start" block without any program running in it at all, the roll block still stops working correctly. Also integrating multiple "while" blocks into a single long monster of a program wouldnt fix it, I just ended up puting the program into a beacon light part and it worked fine then.
@Fyrem0th Carbon fiber just doesnt have a melting point high enough to be used in the regenerative heat shield face. You'd need to pump a ridiculous amount of fuel infront of the rocket for the resin to not melt. You really can only use a high temp metal or ceramic for the job. I think a metalic heat shield is ultimately better than a regen one since, again, it could be lighter, more resistant, more durable, and easier to replace than a ceramic one. Starship also demonstrated that for a large vehicle like itself or Neptune that a regen heat shield would be heavier than a ceramic one. A metalic heatshield would give great characteristics while being lighter than the other 2 options.
@Fyrem0th I still dont think that carbon fiber could be used in a cryogenic rocket engine. There have been cyrogenic fuel tanks made out of carbon fiber, like on the Electron rocket, but those only have to store fuel at about 4 bar of pressure, and the turbopumps of rocket engines need to have a pressure that is higher than the pressure in the combustion chamber, which carbon fiber just cant reasonably handle at cryogenic temperatures.
Having a regenerative setup for the booster return is likely overkill, instead wraping the hot parts of the booster with thermal protection wrap or thermal insulation paint would proabably be enough. Using a regenerative heat shield for the second stage might work, but with a high temperature alloy insead of carbon fiber. Starship had a regeneratively cooled heat shield for a while, though switched to a TUFROC ceramic heat shield because it was ultimatly lighter than having a regenerative cooling setup. Stoke Space is also developing a regenerative heat shield for their Nova rocket, though im intrested how their regenerative heat shield stacks up to a regular ceramic heat shield. Its hard for me to imagine that their regen shield with the weight of the plumbing and the extra fuel needed would be lighter than standard TUFROC, which isnt very heavy, only about 354.4 kg/m3. A TUFROC shield for the Nova wouldnt be hard to replace due to its small size as well. You can also potentualy use a more advanced metalic protection system for the second stage, like the one developed for the VentureStar. A metalic tile heatshield would potentually last longer, be easier to replace, and be a lot more durable than a ceramic tile heatshield.
Aerospikes could potentually be used, I think the challenges with weight and cooling could be solved if the goal of using aerospikes is strong enough to carry development far enough. In some cases the cooling problems of aerospikes could be turned into a bonus, like using the extra heat generated by an aerospike to drive a expansion cycle turbopump that is larger than a standerd rocket nozzle could support. There have even been a few studies done on taking advantage of an aerospike's heat in real life, like the Dual-Expander Aerospike consept.
There have been aerospikes tested that were in the ~100 ton thrust range. Specifically the XRS-2200, which was designed to give 1,192kN or ~121 tons of thrust. Also as a side note, the XRS-2200 was able to use a simple gas generator cycle and still have preformance similar to the Staged combustion cycle of the RS-25 because of its aerospike nozzle.
You mention that carbon composites could be used in the construction of the engine, which is unrealistic. A simple composite like carbon fibers cast in resin can only be used in close to room temperature (depends but something like -50 to 300 celsius.) So the resin would vaporize in the combustion chamber, or crack and shatter in the cryogenic turbopumps. Using carbon fibers with other materials gets really complicated and is not well researched. Using something like molten steal to cast the fibers probably wouldnt work since the carbon fibers would disolve into the steel at that temp.
