Unreliable rocket silos melting

[Tobruk]

Hi, soooo is there a reliable way you can set up a rocket silo so nothing ever melts from frequent rocket use?

• I've tried using steel, obsidian and iron, but given enough time everything ******* melts.
• Also, I make sure to only expose so much of the wiring as it's absolutely necessary (which means going through the walls and then straight horizontally across the silo).
•  Anticipating your question - I didn't put any drywall in the silo. So the gas is leaving as fast as the exposure can suck it off.

There seems to be no way of stopping the rocket from melting stuff. I thing the most infuriating thing is when rockets melt the automation or power of the bunker doors and the entire chamber is later bombarded or cracked by the launching rocket. Even the goddamn foundation from insulated obsidian melts under either the petroleum of hydrogen engine. How can I leave them unattended for the night if stuff like this happens?

I usually put a fairly big steam room underneath, so I get energy back from the heat and keep it controlled. I also put aquatuner inside for liquid oxygen and hydrogen and any other purpose I can have for them nearby. Additionally, putting tempshift plates on rocket allows for even more heat retaining

Run coolant through the walls of the silo and make it airtight. Use a turbine steam room to cool the coolant.

My silo has had 2 rockets launching continuously to the nearest asteroids while staying a balmy 165C, spiking to 320C very briefly at the bottom row only under rocket fire. The copper tempshift plates backing the silo never come close to melting.

This is bigger than what you need for just a rocket or two, but also able to support 4+ tuners on supercoolant.

AFAIK steel was enough, debris from meteor was my coolant back then.

I use bunker doors for the foundation, they did not fail me yet. Bunker tiles for the silo, worked for me. Obsidian tiles as drywalls, also no melting. The automation wires are tricky, the 3 center tiles get very hot, especially with hydrogen engines. I avoid these 3 tiles, if absolutely necessary I use thermium, but I think tungsten is even better with a melting point of 3421 it should stand the heat.

The solution is active cooling. No material can actually handle the temperatures reached by rocket exhaust (3200K in some areas), but they don’t need to. Pipe liquid/gas through the walls or dump some sort of coolant directly into the chamber. Don’t launch again until you’ve cooled it back down.
