Rocket Engine heat

[Oni Noob]

Hi Guys,

 

Any tips on preventing the heat from Rocket Engine from entering your base? How  many level of Bunker tiles should I put beneath my rocket?

I am currently in the process of trying this out, putting a vacuum room below the rocket

Personally i just make 3 rows of bunker tile "padding" below it, encase in insulated tiles and snake my meteor petrol cooling system  through it. That way every time rocket launches my steam turbine turning heat from falling meteors into power gets a noticeable boost from rocket heat, while preventing it from seeping into colony. And since cooling system goes through one side of map to the other in space it's naturally close to launching site.

This forum has one of the worst search / archieve mechanics i know.
Did you give it a try, before you suggest stuff?
Search for "Rocket engine heat"..

[Xyer]

I did use the search function to find the thread that I posted, although the exact search term I used was "rocket heat", 

I just tried "engine heat" and it gave an answer to OP's question too. I don't see why trying different search terms can be difficult?

When you know, what you have to search for, because you know already the answer / found related topic, search behavior may differ..
Many new players are entering the arena every day and same questions are asked weekly, that's relative normal, when "normal" exists.

Let's just help the poor fellow...

First off, I wouldn't build bunker tiles below or around the rocket. They don't isolate very well and steel is very precious.

 

Instead I use ceramic around it and of course bunker doors above it. That will insulate a lot better already. Next, I launch the rocket from a large pool of water. That will act as a huge heat sink.

 

I have not launched rockets in a very long while, so my info above might be outdated. But this how I basically launched my rockets and that worked for me really well.

That`s where the heat will magically appear. No need to use insulated tiles there. It`s actually worse as those tiles won`t spread the heat around and will eventually turn into magma. As mentioned above just put water there and use it to power a steam turbine when it eventually heats up. A more complicated design would involve tungsten metal tiles and radiant pipes using super coolant to transfer the heat away (again to a steam turbine).

In general, to prevent heat of leaking in or out of something, just leave a vacuum gap. The rocket silo is absolutely no exception to that rule.

 

With that said, I store LOX and LH2 right next to the rocket silo insulated with only a single layer of ceramic, so I am pretty sure that will  also work in insulating the rest of your base from rocket heat.

unless it has been changed the rocket engine doesn’t need to be placed on a floor so just lower your tiles and then you don’t need to worry about melting them

I tried doing a vacuum gap but tile only melted and it let all the gas come in. Ill try using water as a heat sync but it make take time to work on that in survival mode.

Question does Solid Fuel Thruster produces heat at its bottom ?

Do you have a good layout for this. I been planning to do that for some time but not sure whats best way for the steam to be transfered to my steam gen

Why not leaving a 9x3 gap?

@Oozinator You picture is worth a 1000 words, made a little bit more accounting for inflation

@Oni Noob The below video covers pretty much all the info you need to understand the basics of rocket exhausts, it's an amazingly common question. I only created it as a side note but I have lost track of the number of people I have linked to it. I'v skipped it to the relevant 60 seconds of the video.

Hi Guys, What you think about this setup, ill add more water to it and once its high enough ill start my rocket to heat up the water and create steam

I would recommand a double layer bunker tiles under the rocket.

(A comet can damage the tile it hits and the one beneath it, so 2 layer bunker tiles or an "empty row". PS: Remove the mesh tile^^)

I wish all the heat from rockets was from the exhaust. It makes more sense that way, people would ask less questions, and the optimal launchpad designs would be less unintuitive.

 Its a failure after multiple launches my steam generator is still not running

I'd bet you would have better luck with a significant decrease in the amount of water. 70,000+kg of water can absorb a ton of heat before boiling.

But if its too little it wont get reach my the flame of my rockets. It boils after more lunches but still not enough

Yeah. That's the rub. You need enough water to absorb enough heat to boil but not too much water to delay boiling. I've been using around 20kg per tile in the room so that there's plenty of steam pressure once it's up to temp.

If you don't want to reduce the amount of water, try putting a couple Aquatuners in there or run some high temp petroleum from metal refineries though radiant pipes in there to help heat up the water between launches. Once you get the water to 100C or so, it shouldn't be long before it steams off and stays steam.

Make a 3wx9h vacuum beneath your rocket engine and don’t get any heat at all....only the 3 center tiles the engine stands on directly will get heated,

Its now working perfectly, I just drop a magma in the hole below my steam engine

lol "perfectly".
