Ju-88 random overheat/engine failure

[SvAF/F16_Dark_P]

Sorry if this have been reported before but i could not find anything about it...

 

I have some serious problem with the Ju-88, i getting random overheat and engine failures on the engines, sometimes it is number one that randomly overheats or number two, it happens when in a climb in climb settings (88% prop and 90% throttle) cowl flaps fully open, temps are normal ~80c ~100c oil so i am not overheated? acording to instruments....

 

This happens shortly after takeoff after maybe 10-15 min, it depends it all comes totaly random.

 

I have no memory of this happening before?! Is it a bug? or am i doing something wrong? Or have something been changed in some patch?

 

Regards!

It's probably not random.  Keep an eye on ATA.  Speaking for myself, I can't get the German bombers off the ground without harming their engines.  Could be that you too are pushing the plane too hard for too long on takeoff.

 

Whatever the case, I'm pretty sure that overheats are related to engine mismanagement.  That has certainly been the case with me.  When I first started playing I burned out 109 and 110 engines on a regular basis.  I learned their limits and now it doesn't happen anymore.

Maybe i pushed to hard on take off then.... but still feels starange, i fly her as i have always done, never been a problem before and i fly by the manual, this happens randomly... if the guages shows normal temps how can they overheat then?

There's no way this is random. If you run the engines within the prescribed limits you'll be fine. I have flown the Ju 88 a lot and have never had a problem with the engines failing.

Hmm.. that is what i said, engines was within the prescribed limits yet they failed...

Anyway i have been flying now for a while just now, and it did not happened again, maybe a fluke then....

Best to record a track and go back and review what happened - even share it here so we can have a look.

 

I've been flying the Ju88A-4 a bit recently and no problems so long as I stayed within paramters for ATA and RPM as well as keeping the cowls open on climb out (I made that mistake on my first time back in the cockpit :)).

Hmm, I don't remember the rpm and ata limits. I'm just pulling this from back of my memory but I use 85% throttle and rpm for climbing and I have not had problem with overheating.

Could it be they are damaged when reaching second stage supercharger altitude and you get a sudden surge in manifold pressure? You ahve to react quickly then to reduce power.

85% Prop, 85% Throttle and Aircollers 100% open and you can 1/2 Hour climb with no Problems

What is your climb speed?

[Yogiflight]

And the air temperature? It is quite hard to overheat in Moscow winter, but pretty easy in Kuban summer. Especially with low climb speed, as Browning asked, with low airflow to cool the radiators.

[6./ZG26_Klaus_Mann]

Run 85% on Props and Throttle (2400@1.25ata) 1.3ata and 2450 RPM shortens the Engine Timer a lot, which is what OP is using.

Climb at least at 250km/h, 270 is better, slower than that causes overheat.

Especially above 4000m it is important not to slow down, as the thinner Air doesn't cool the Engines as well.

As soon as you have cleared the trees, reduce to climb power, flaps up, accelerate before you continue the climb. No need to take max climb power, as Klaus says keep a little safety margin and always check the instruments and not the tech chat percentage.
