reported Engine overheating?

[MAD-MM]

Hope some of the mods @BIGNEWY have look here before we get to the Point sorry the Track doesnt work anymore because a Patch droped.

I'll be reviewing soon.

[Hobel]

I played and recorded the track up to the point where the engine takes damage until it dies

at min 28 the interesting part starts, I can't see why the engine dies, he flies quite gently goes briefly into WEB and after a few seconds the engine dies, Temp have also been in order

I added it to the report, I did not see anything to cause the overheat.

yup. same sound i heard often enough out of nowhere and then the engine dies for no reason.

[grafspee]

I think that overheat is just aftermath of failure. Engine dies and then temps sky rocket happens. 

[OLD CROW]

Time: 28:25 ATA 1.41 Oil Temp: needle between normal and high reading

Time: 28:39 ATA 1.72 Oil Temp: needle goes to max. mark reading

Time: 28:46 ATA 1.7 Oil Temp: needle drop to normal- high reading      At this point the engine sound changes

Time: 28:56 ATA 1.65 Oil Temp: Up to Max. Engine totaly fried giving its last breath before total dying

Time: 28:59 ATA 1.58 evident loose of power 

Time 29:05 Old background sound (like if the pilot opens the canopy and the air blows direct in the ears) of total engine failure. 

I've never owned the Dora also never have tried it out in the trial mode, but first time I've watched Hobel's vid it recalled me, like 2 drops of water, same engine total failure in the P-51D Mustang, before inplementing new coolant system. Maybe is a hunch... but maybe 10 years ago engineers did a kind of copy-paste from the previous model (TF-51/P-51) DM scripted model and implemeted it in the Dora DM one and they'd also copied, unwittingly, the issues it carried. I have NO leads on that I only try to help the team pointing out a possible starting point from where searching and fixing the issue/es.

The last time I flew the Dora without constant engine problems was around the time the original Normandy map was released in 2017.

An update shortly after that broke the FW190 engine and it has been broken ever since.

It's rare to fly this thing without engine trouble, it is incredibly bad. It seems to possibly be linked to MW50 use but who knows. Just can't believe it has been broken for so long.

I really loved this plane when it wasn't broken, was a blast to fly. But that was about six years ago now.

 

 

[Doughguy]

Its soso. In fly her regularly but the bug occurs pretty rarely but i also had it like 2 3 times in a row which made me think its related to warmin up procedures. But it even occured when doing it strictly by the book.

And even if mw50 isnt involved at all.

Temps indicate solid 120 throughout the fligh or less depending on ata/rpm then you push the throttle past 2100 rpm to 3000 or higher quick uproar engine dead at an instant and oil temps are suddenly above 130.

Only quickly cutting the throttle, opening rads and pulling the notzug handle prolong the flight... but you're rather strolling home and delay the evident...

I think in my first track this can be observers iirc. 2nd sorties. Start, cruise etc temps all good. Flyin 2500 or so rpm. See a contact throttle up to 3000 bang. Instant engine death.

The only constant i see usually is that the radiator flaps are closed each time the engine seizes and oil is 130 plus. Coolant is ok iiirc.

And i usually never touch the flaps. Not even for t/o. Not even the real pilots did as per accounts.

If the system malfunctions due to damage, ok. Bad luck. But out of the blue just cruising? Unless of course random failures were on or were triggered but afaik these arent on on 4ya... and it happens toooo often if hardcoded...

I am finding that manually operating the radiators helps a lot.

[Lixma 06]

Air start - engine lasts 80 seconds before failure, MW-50 on, temps fine according to gauges. Didn't touch any radiator controls. I flew the same mission again immediately and everything was fine.

Will take a look, thanks

 

[Doughguy]

Could the culprit be identified or do you need more tracks @NineLine?

@NineLine another dead engine with temps ok. same short uproar and death no matter how fast i pull back. 

again, temps are ok, you hear the uproar, then temps start to rise and engine death can only be delayed

Occurs in the first half.

I also have some lagg down low which seem to appear only since 2.9... not sure if its visible via track but eg occurs when i try to land at carpiquet after the engine siezed. right before touchdown i get serious lagg.

@NineLine Anything?

[Doughguy]

Happend again for no reason, can provide track if necessary.

@NineLine @Hobel Had this again after a while.

Warm up with 1500 rpm until coolant reaches 50 deg. then to 1800 rpm until 70/80.
Rollin. Climb with 3000 rpm. Cruise with 2500 rpm at 6k.

Noticed some vapor clouds at my back but thought they were reflection. Then large vapour clouds from the front. 
Landed her with low engine settings around 1500 rpm with gills opened up all the way since the dive.

I set her down, and left her idle at that for a while. Engine runnin smooth at 1500 rpm. Coolant 90 deg. Oil full blown at 130 since the vapour discharge.

I left the gills open all the time and played around with the throttle. 2000 rpm metallic sounds could be heard.
Throttled back to 1500 rpm, running all good.

Back to 2000 rpm, metallic sounds back again.

Pushing it to 2500 rpm then broke the engine.

Any form of info would be highly appreciated on this... its going on for way to long..

.

I have not yet been able to reproduce this, the failure seems to be very random at first.  

I will have a look at the track and try to reproduce it again, but I can't say when and how long I will need.  

[Doughguy]

Thanks @Hobel

I wonder if the bug could be identified. Theres been many tracks submitted, includin by you.

However Nineline went pretty silent.

[Doughguy]

Oh well... new update new track huntin.....

[Doughguy]

@Hobelanything?

WOLF_PACK_US_WWII_DYNAMIC_BASE_CAPTURE_v5.1.1U-20240727-184421.rar

engine stopped midflight. Oil and Coolant Temp all in the green. No other damage that i could assess.

@NineLine@Hobel

[Doughguy]

Was told this bug was fixed internally with the latest update.

It appears the temps noq rather settle around 110 deg oil when cruising 2500 rpm instead of 120.

However, been told by 2 people already that the engine still died for no reason when cruising and then full throttle.

Same phenomenon.

I have no tracks yet.

Could a dev confirm this was worked on?
