Blue Jet Engine

[Geometrian]

After a SSTO was destroyed at a critical moment, I reproduced the problem: overheating. It turns out that overheating jet engines glow blue (which makes some kind of sense, but I didn't realize was implemented):

I hadn't seen anyone notice this before, but I thought it was kindof pretty. The small rockets are angled toward the jet; the screenshot was taken a few milliseconds before the jet exploded.

OOOH, that's pretty. Any mods installed that might be doing this?

[sal_vager]

I can confirm this, no mods required

Nope. My install is entirely stock. Not even MechJeb. Put three Rockomax 24-77 engines spaced around a turbojet output, angled two "SHIFT+W"s inward. That makes a fairly stable example for a turbojet.

It's also possible with a standard jet engine:

so pritty, i love little things like that

If there were to be Ion-ish Jet Engines in KSP, this is how they probably would look like after thrusting up.

Although when i clicked the Thread, i expected a jet engine with black parts it normally has, coloured blue.

Wow. Never knew that, probably because I can't think of a scenario where a jet engine would overheat.

Yesterday I was testing out my first plane that actually worked and it began to overheat when it experienced flaming reentry effects at 1km/s in the upper atmosphere. I did have Interstellar installed though, and before it exploded the engines turned themselves off.

Many engines do this, for example the Skipper turns blueish-grey.

That looks so cool. Too bad these blue overheating effects are given to engines that never overheat.

I believe the Areospike does this and so does the huge turbo jet from B9 its been in for a while.

Cant say i have ever been able to get a jet engine to over heat

[Geometrian]

I've noticed that KSPInterstellar exaggerates the problem. Here's an attempted SSTO burning blue:

I've noticed that in this case, the engines power off automatically. I believe this is KSPInterstellar's doing. The exact same aircraft without it doesn't overheat.

Though, it doesn't get to orbit; for that you need this:

That makes a lot of sense great attention to detail squad

[prophet_01]

That's rly cool. Too bad that they need to be that close to explosion. I recently tested a new SSTO with jet engines (mods: b9 qnd FAR). I actually had some overheatoing in the upper atmosphere due to mach limits by b9, but it wasn't enough to trigger the blue effect

I saw it here for the first time. Thx for sharing this btw. It's a rly cool detail

[lajoswinkler]

Actually they aren't exploding. They are merely going to the future.

I actually overheated a turbojet engine on an SSTO on the ascent to orbit. It was in the center of a cluster. Luckily, it ran out of intake air and started to fart the deadly flat spin sparks, and I regained control easily.

LOL speak for yourself. My mainsails frequently overheat if run at full throttle. I've heard theres a problem with how they conduct heat to the large orange tanks, though, which is where I usually have them mounted.

Doesn't interstellar require intake pre-coolers for air-breathers at high mach?

Mainsails don't have the blue effect, though. Skippers do.

[HafCoJoe]

OHHH THAT'S PRETTY!!!! Time to abuse.

[waterlubber]

I tried it myself, I found that by varying the thrust of my Bad-Idea 9000 I could change the color of the engine in interesting ways...

but hey, at least we can have Jet Blue!

Also, I tried it with a skipper:

Pushed it

And this was a really cool shot of the apparatus after the engine...was removed.

Aerospike:

Looks absolutely amazing

It happens often with my SSTO when I'm at 10K meters. At this altitude you start building some real speed and the air flow gets very important thus making the engine heating. Once you climb to 12K it's ok because the atmosphere is less thick. However you need to stay at 10K for some minutes to allow the engine heating.

I also noticed this on my SSTO a while back.

Your picture is much nicer than mine

[zekes]

Still very cool, and beautiful.
