1.0.4 : battery bank exploding in space due to overheating after SHORT bursts


Recommended Posts

The only reason I can imagine for this is that the ship was flexing quite a lot, but I only fired the engines for maybe 30s, and the batterys are very far from it.

Mind you, this is a 1.0.2 ship, so without radiators.

Is this to be expected ?

THat would mean i have to rebuild every ship which would be slightly painful

This is a case where a picture of the ship (or even better, the event happening) would go a long way towards helping us help you. :)

Random stab in the dark: There seems to be some issue with low mass items tucked inside service bays overheating, that could possibly be it.

according to the autosave (which was maybe 1 min before the explosion) it seems

- the 2 nuclear engines have temp = 356

- the hottest battery bank has temp = 338.815503555444

which doesn't seem that hot (60°C or so)

if anyone cares here are links to

- the save : https://www.dropbox.com/s/enlvrio2vmkw2vr/overheating.zip?dl=0

the faulty ship is "Minmus Bus Probe" in orbit of Minmus

- the ship description from the save https://www.dropbox.com/s/1buw54s20h24nse/overheating.txt?dl=0

- a screen shot of the ship just after the explosion, the battery was where the temp markers are

I tried your save game, and while I can't say precisely WHY this is happening, I think I have an idea of WHAT is happening.

There are two "bugs" at work here conspiring to blow up your batteries. There is an issue with low mass parts experiencing runaway heating, and the service bays are also doing weird things with heat. In your save, everything around the service bay hits almost 700 in less than two seconds. I'm not sure why that's happening or where the heat is coming from.

Since I see no way around the explosion, my suggestion to you is to utilize the Alt+F12 menu and select "Ignore Max Temp" either before you load, or right after, then reload the quicksave. Let the runaway heating finish, then you can enter 1000x timewarp to equalize your ships heat and then turn the f12 menu option back off. This may not be an ideal solution, but it's definitely buggy behavior and there's no standard mechanic you can use to save the parts, or at least none I could figure out.

Thanks for the time you took looking at my case .

I'll definitely try that, especially as, having accepted the battery loss, when I came back to the ships a few Kerbin hours later, the ship had disapeared without a trace, there aren't even a debris orbiting Minmus , i Have no idea what happened

edit : just tried your suggestion, and shockingly, overheating didn't even occur ... I had also turned on thermal data and thermal debug colors, and no part in the ship changed color
