[1.0.5] Atomic Age - Nuclear Propulsion - Red Hot Radiators

[gilflo]

I have it install too and got the bulb engine in tweakable versions on some aircraft. It was working fine on 1.0.4 and I got big heat problems with 1.0.5 on the bulb.....They would heat and explode very quickly after start....

It looks like when the bulb engines are exposed to heat du to acceleration, when over 20km building speed to M4.5, when I stop my scramjet and start the bulb, they heat very quickly.

If I replace bulb by  stock LV-N, this won't happen.

If i use bulb engines on Mun for example they won't heat.....

So it looks like they can't be use after general  heating du to acceleration or whatever else

Any hope for an update?

There's big heat trouble on 1.0.5

[fourfa]

Just started to play with this.  I was hoping to find some translations between the older heat model and the current 1.0.5 here.  I'd like to edit the tooltips with guidance on how much cooling to use, for instance like the stock ISRU and drills have.  

Don't see anything like that, so I figured I'd throw what I've found up here.  I only tested the Lightbulb engine, as that's what I downloaded this for.  Two medium Thermal Control System active radiators (stock, 500kW) can't cool the Lightbulb on the Kerbin launchpad at 100% for terribly long.  Two large TCS radiators seem to slowly reach equilibrium, or very close to it at around 1550K. So can we guess that the 2000 "Waste Heat Rating" has more or less the same units as the 2000kW "Core Heat xFer" of the TCS radiators?

Any hope of at least a quickie documentation update?

Please update it, it looks cool and I am planning to download this..... BTW, guys who have downloaded this in 1.0.5, is it playable....or no?

Many thanks (of fuel)...,

I built some fantastic vehicles using the bulb atomic engine, the only nuclear gimballed engine, they 're working fine on 1.0.4 but not playable on 1.0.5 because of the new heating system. Atomic bulb engine will heat and explode quickly , even with a ton of radiators!! I guess it's the same issue with other Atomic engines....

i am waiting for an update too.....PLEASE....

Not to hijack Porkjets thread with my entirely un-porkalike projects, but "Heat Management" in my signature will take care of that for you, at the cost of extra mass (and a touch of electricity).

[gilflo]

Thank's Randazzo, i know your mod and I'll give a try to see if it can cool the Bulb engine....

[gilflo]

Well, With all cooling system, it's working as long as you don't run them in  a hot environment.....

If I start bulb engines at 28km, M 4.5, temperature not increasing any more, with a 500° margin from max temp, even with Heatsink, AHMS and radiators extended, they don't live more than 15sec, temp is increasing very quickly.

There's no temp problem in the same configuration with the stock Nerv engine, that's why I think they need some update....

[Jimbodiah]

These engines are all (not sure on the jet engine) included in the KSP Interstellar Extended mod and working fine.

Did you start the bulb engineat 26 km when temperature is around 1500° ? I tried on my SSTO and even with all the cooling stuff they overheat very quickly, while the Nerv engine works fine and even its temperature decrease.

If you start your bulb on the moon in the cold it's ok..

the description of this mod makes kerbals seem intelligent!

[theonegalen]

Threw together a quick MM cfg to add core heat to the Candle, and add a few other 1.0.5 features to the rest of the engines. Mostly took numbers from the Nerv and the PB-NUK. Seems to work. Can run the lightbulb with the included 2.5m radiators all around as in the picture on the original post almost to the end of an orange tank on the launchpad. Will run indefinately at 80% thrust. I'd like to add a core heatingmodule to the lightbulb, but I'm not sure how to make it accurate. Use this at your own risk.

I've only tested these on the launchpad so let me know how they do in space.

Thank you. I'd been looking at doing this myself. Hadn't got anywhere near as far as you have, though.

[gilflo]

Hi

thank you, but how and where do you put this in the game folder?

[Stone Blue]

@gilflo Just copy the text theonegalen posted, open your favorite text editor, paste it, save it (put .cfg in place of the file extension), anywhere in Gamedata folder.... You may put it in the Atomic Age folder to keep it with the mod, or as some people do, put all their custom patches into one folder to keep track of them, even after removing the mod... It really doesnt matter WHERE you put it, as long as its in the Gamedata folder, or ANY sub-folder there-in.

@gilflo What @Stone Blue said. 

I have a subfolder in my KSP Gamedata folder called "Galen" where I put all my cfg edits, custom flags, etc. You might want to do something similar in your install. Make sure you've downloaded the latest version of modulemanager to install to the GameData directory.

[gilflo]

Ok guys thank you

I'll do that

[Timo M]

Thank you SO MUCH! just what I wanted... high TWR Nuke engines!!

 

[maverick8717]

I am using the bulb engine on a big ship, I have plenty of cooling and it has been working great, 20 minute burns no problem..  however now I am getting prop requirement not met...  and it is throttling down to 10%.. anyone know why?

[Jimbodiah]

Run out of nuclear fuel perhaps? They have a limited lifetime unless you replennish them.

[agent 902]

Hey @porkjet! I was wondering how that habitat pack revamp was going,im realy excited. Cant wait. I thought this owuld be the best place to ask you.

So--somewhat irrelevant question: can anyone indentify the cone-shaped command module in the last spacecraft picture in the original post, Page 1? I've been trying to reproduce various spacecraft from this pack (since I don't really have good techniques for designing nuclear spacecraft), and i can't place it. Is it from a mod? It looks like an updated version of old nosecone from before 0.90, but I can't place it.

I'm not at home, but I will check when I do get home because I was wondering the same thing... 

Could it be a 0.625 to 1.25 m fuel tank adaptor?

/Also looking forward to a 1.1 version of this mod, if ever Porkjet decides to abandon the toil of SQUAD and rejoin the toil of modding-for-free

It seems to have a "native" antenna (in addition to the big Squad one)--so i doubt it's an adapter?

It appears to me to be a rescaled (i.e. TweakScaled) stock avionics nosecone, but I'm only 99.3% sure about that.    If you don't recognize it, it may also have been retextured by Ven's Stock Revamp mod, or another retexture mod, perhaps.
