[FIXED] Issues with MW50 usage.

[coopes]

Hi gents,

 

have the same results as you, when i dont work with the coolers. In the moment i use all the way in dogfight the cooling system. Open it as soon i hit the water max., let it open till fight is over and close it again when the engine is realy coolagain. Than back to auto rads. No problems to run MW50 longer than when you use it without "manuel" contoll, as i think the automatic dont open the cooler rads to the max. when the temps raise to max. Because with open rads and max. power +MW50 i have temps around 70 water and 80 oel the complet time. It takes a lot of time for the temps to raise to max. more time then you need to run for everybody over the map. never got engine failer because of temps with "manuel" use of cooling system.

 

regards

I ran my Test using manual cooling

Than back to auto rads.

 

 

Hi,

 

:dunno: FW 190 ? - Can't find nothing about auto rads

Do you mean : Adjust the "Manual Radiator Flap Control Knob" until the coolant temperature is 100° C ?

 

 

The P51 has Automatic switch positions on the Radiator Air Control Panel

[Magic Zach]

In the P-51, provided everything is set right, you can fly in level flight at SL, 3000RPMs and WEP and not overheat (though it will be close to the "danger zone").

Only use WEP if you really need to "sh** 'n git."

The rads are always automatic unless you open them too much, then they will stay open. If you close them enough they'll go back to automatic mode

Hi,

 

Thx

I was a little confused by "auto rads". For me it sounds like a switch position

Weird, very weird.

 

i was testing the FW-190 with radiators fully open manually and my engine breaks 4:30 minutes after engaging the MW50.

 

All the times......

What happens with radiators fully closed?

 

This MW50 induced engine blowup problem doesn't seem to be an overheating issue based on other comments. I bet it's something to do with the engine durability model- they've put a decimal place in the wrong spot or something, and the engine wears out very quickly when MW50 is engaged.

[LeCuvier]

Iwent through the entire flight manual but could not find the rules about 10 min with MW-50 followed by 5 min cooling down. What page please?

Also in all the posts about tests with MW-50 On, I did not see an indication at what power setting they were running. Is it implied that they were running at full throttle?

I can confirm. It happened to me several times today. Radiators wide open, engine stops all of a sudden..

Hi LeCuvier,

 

MW50 can only be used with full power setting. The time rule is stated in war time manuals.

When D-9 was released as a final product (DCSW 1.5.xx) i tried how long is she able to fly with MW in non combat conditions on map with default weather. It was somewhere 17-18 minutes repeatedly until engine died.

 

Today tried it with the same conditions on Normandy map, with result somewhere 5-6 minutes until engine died with one exception... I tried it 5 times, 4 times with that short result and ones engine worked 15 minutes with MW.

 

Always i flew at low altitude MW was switched after i reached 500km/h and my speed did not fall under 570km/h with MW.

 

Coolant temperature was always 100°C (may be 102 or 103 :smilewink: ) and oil temperature, needle held uper limit mark from allowable range (whole flight).

 

edit: radior was always set AUTO, i did not touch it..

Have you tried different times for the first usage? Not taking it to the 10 min limit the first time?

[Esac_mirmidon]

When i open manually the radiator flaps my engine breaks in the first time i use the MW50.

 

So is not at the second usage. is on the first try.

 

If i left the flaps on auto, the engine last longer, always the first 10 minutes, and always breaks afted 3:30-4:00 minutes the second.

 

This is why is so strange. With flaps fully opened, my temps are below the max all the time but the engine breaks even in the first 10 minutes period.

[NineLine]

Can you guys include outside temps when reporting as well. It does seem to make a difference. I am looking into it, but the operational limits are a bit foggy. Either 30 mins, or 3 bursts of 10 mins with periods of cool down.

 

My concerns are that pushing the system to 10 mins may be considered abusing it, especially if the temps outside are higher. So even if you cool it down, the engine has already been beat up. THAT SAID... I would like to see more visual cues my engine is upset...

 

Now, dont get me wrong. I tested last night, it was -5 temps outside. 10mins of boost and my engine tanked 2-3 mins into my cool down period. So either we are doing something wrong, or there is another issue.

 

So I am looking into it, I just want to understand as much as I can before I report so Yo-Yo doesnt turn me inside out with facts :D

[Esac_mirmidon]

All my tests at 15° and sea level.

SithSpawn is there any feedback on this??

 

I have searched everyone, also own the 2 great Dora books by Jerry Crandell.

When i read up on the MW50 i get the same info that it has enough to run for about 3x10 min periods with a 5 min 'cooldown' between use.

 

It so obvious that this is not acheivable in the sim. Temps will only really have an impact at high altitude due to the cold temps plus the cooling nature of how the MW50 works in the engine. ie cooling the engine too much or freezing.

 

Certainly flying around Normandy on a nice summers day between 0 - 6KM the MW50 can not be run for the periods it should. Again i point out that the 109 even breaks the 3x10min rule as you leave it switched on and can go from 1.45ATA to 1.8ATA all day long.

 

What gives?

[NineLine]

I have asked, I havent heard anything back yet.

Thanks for your honesty.

 

Im disappointed to say the least :(

I'll try and kick this can again, been busy with everything going on, things can get missed.

[antagonist]

All my tests at 15° and sea level.

 

Well, considering the plane was meant to fly above central Europe, I think we can assume the engine limitations are meant to be taken as limits for more extreme temperatures at the outset, with your test being smack dab in the middle of the ambient temperature range the engine was designed to run at.

[coopes]

I see the MW50 is still borked in 2.5 :(

[Brigg]

Yeah Please fix this asap ED.

[Anatoli-Kagari9]

Yeah Please fix this asap ED.

 

What exactly is broken ?

[razo+r]

What exactly is broken ?

 

Maybe you should read through the thread?

 

 

MW50 can not be run for the periods it should.

 

[MAD-MM]

From my understanding the Problem with Dora Engine is not only related to MW-50, buried little bit deeper in the complex Engine Cooling from the Jumo.

You can kill your Engine still after short period of MW-50 Flying, when you start to reduce Power...

There was some time (still there not sure) when 109 Oil Temperature goes over the Red Line it will never come Back even when you shut down the Engine.

But what ever is the cause for this, WW2 is currently really Frustration with the unsolved Dora and Spit Problems.
