Gantry alway get burned?

[SamLogan]

Hello,

I'm trying to construct a rocket launcher but I can't find a solution about the gantry :

- It get burned when the rocket leave and come back.

- It get burned in a vaccuum if it plugged to electricity.

- It get burned if it in contact with other hot material like bunker.

I've try to put a cold gaz but the hot CO2 heat it.

Any idea?

Here's my setup :

It doesn't need to be connected to electricity, and it doesn't need to be retracted.

Gantry seems a bit too close to rocket judging by position of pipe. Try moving it further.

P.S. For me they constantly overheat... sometimes rocket blows some regolith onto lowest gantry and sometimes I find regolith on top one and I have no idea where it came from (bunker tiles above gantry and bunker doors above rocket).

Yes, you're right, but even that, when the rocket pass by the gantry, it get burned by the flame.

I have the engine submerged in a pool of water 4-5 tiles deep, and a radiant pipe running up the center of the launch silo with petroleum coolant constantly cycling.  My setup is far from perfect, but my gantries don't seem to burn up anymore.  I also have the silo pressurized, so heat can effectively move around.

Here's the rocket in dock.

I don’t think dupes care about decor when they are in suits. Or at least they didn’t. Nice rocket station.

How much co2 does a launch produce?

That's a tough one to answer accurately, but when I just test launched it to see, I was reading 6Kg and up at the bottom, but only ~600g at the top.  Currently pumping out the room into tanks for a precise measurement.  I imagine it'll vary depending on the size of the rocket, and the size of the launch silo.

Interesting, you water don't get vaporized?

By the way, here's the heat dispersion, if it can be usefull :

I expect so. Any amount is great for slicksters.

Nope, not sure why, some of it should.  My plan for the water pool was just to have a huge thermal mass to sink all the heat into so it didn't melt everything instantly, but it seems to handle the heat very well.  Might just be due to how large the pool is, or it could be a bug, and hell if I know which.

[0xFADE]

I would expect it is exactly because of the thermal mass. That is quite a lot of water. 

[TOOK14]

Well, before my rocket came back, it seemed like I got almost exactly 700Kg from launch.  Now I'm waiting on how much I get from landing, which I think will be less.

Man was I wrong, seems like I got about 1 ton of CO2 from landing, for a rough total of 1,700Kg of CO2 from one round trip to the nearest destination.  Again, I feel like it's largely dependent on the weight of the rocket, and how long your launch tube is.  I think it'll produce so much CO2 per tile traveled, with some reduction for every tile it's already moved.

Still, that's a lot of CO2.

Pictures for reference.

One thing I will warn about my setup, make sure all wires are tungsten, any other material instantly melts when the rocket booster moves over it.

Final count is 1581Kg of CO2 round trip, minus whatever escaped during launch and landing.

Were the wires exposed?  My iron wires were 500-700C so didn't melt but they were running inside the bunker doors that were opened for the launch so I expect the doors could have taken much of the energy. 

[TOOK14]

Only the wires in the path of the rocket, the gold pumps on the side had no issues when the rocket landed.  Automation wires in particular are very vulnerable to melting this way, probably due to how low mass they are, so any stray heat being thrown at them is more than enough to melt them.

I'd be interested in that as well, since we can effectively recycle quite a bit of our fuel if we can conserve the co2 and convert it with (molten) slicksters.

[TOOK14]

I am also just using gold for everything that doesn't need some other metal, so maybe iron will be fine.

Yeah that was the idea.  I don't know what a launch costs either.  1700kg from a trip.  Perhaps a longer tube nets more.  That is around 850kg of recycled petroleum.  I'd presume they output as much co2 as petrol based on the rest of the games conversions.

I bet a rocket from the very bottom of the map could produce surplus amounts.

Yeah, i kind of suspect that a constant co2 emission is being used as well. By that logic we might even gain mass from launching rockets.

[SamLogan]

Ok I've a found a solution :

By placing the bunker tile like this, it will protect the gantry from the flame. It takes only few degres heat that can be manage with a PO2 cooling system. Without that, it burnt instantaly.

vacuum and drop 10g/s water

 

[Hellshound38]

cold gantry launch after launch,

Of note I built that vacuum tunnel on the right by simply constructing a tube that went into space and leaving it for a couple hundred cycles until it was vacuum, in order to save myself abysallite while I did other things. 

Space meteor barrier that destroys regolith before dropping it, and rocket launch pad that sucks in the regolith and vacuum seals it as well.
