It appears that the old radiators and oil tanks from the 109s weren't scrapped, they were put into storage to be reinstalled in the Dora. Whats up with the engine seizing in the Dora 30 seconds after the radiator gets hit? And whats up with the big assed AckMagnetŠ on the Doras engine? Every single hit I've taken from ack has knocked out the radiator or the oil tank. No other systems have been touched.
-
Didn't you know Raub, the Germans stole the AckMagnet@ technology from a capture Russian Yak-9U.
Agreed its a real problem (http://bbs.hitechcreations.com/smf/Smileys/default/frown.gif) On several aircraft types

Well, it is an inline engine (the radiator is round and on the front of the engine). Water cooled inlines never were very durable.
The speed at which they seize up may be scaled to the terrain, where a friendly base is only a minute or two away.
Otherwise, why have radiator leaks if they never actually cause alarm to anybody?

Why would it be scaled to the terrain? Does that mean it varies with the map? lol. A P51 can fly forever with the radiator shot or the oil tank shot. The 109 used to seize in about 30 seconds...turned out it was wrong, and it was fixed. Ju-88s have annular radiators too, dont lose the radiator in them everytime I get hit. Just pointing out that something seems to be wrong with it, maybe it should be looked at.

Raub what i find even worse, is that the FW190 with the radial engine often has a total engine failure after one ping to the engine.
The BMW801 was nearly as durable as the P47 engine, more than once a FW190 returned with 1 or 2 cylinders of the BMW801 shot away.
But in AH much to often, i am a glider after one ping to the engine.

Agree.
Its a major problem getting the short end of the stick in a 90 degreee 5G 500 yard snapshot.*Pling* engine smoking and u know ur ded.
Goes for the Ta152 as well.
The 109 series was notorious for the fast engine seizure because of never installed stopvalves (right word?).Anyone know if such was installed in the Jumo's?
Julius Meimberg in a G10 december 1944:
" I repeated the procedure with a third flight; but this
time 1 got too close to the P-47 I was firing at, so that
pieces of the downed bird flew about my ears, and when I
pulled up I was trailing white smoke. Once again I lamented
the absence of a radiator shutoff valve. This time I de-
cided at once to bail out, for trying to descend to safety in
my crippled bird would have been hopeless as the sky was
now full of aircraft, all of them hostile. As well with a
damaged radiator I had little time; in only a few minutes a
piston would seize and that would be it; it just didn't work
without coolant."

Naudet that was the most BS thing I have ever heard. The BMW 801 Radial was never in the same league as the Twin wasp or Ash82 series of radials. One ping and the pilot was reaching for the canopy release. The reason is incredibly simple- the BMW Radial had fuel injection- crack a cylinder or damage the walls and the fuel injection sprayed fuel all over the engine compartment while still trying to ignite it. The 190 had the WORST fire problems of any German fighter because of this.
-
Don't hijack my thread. This is about the Jumo213 not the BMW radial. I agree Verm, I've noticed the same in the Yak.

Danish,
Bf 109F-( something ) had them, and so did K-4.

<<<A P51 can fly forever with the radiator shot>>>
Is 90 seconds forever?
ra

Well, obviously 'forever' was a metaphor for a 'very long time'. (http://bbs.hitechcreations.com/smf/Smileys/default/rolleyes.gif) As in, it runs much longer than most other inline engines with same damage.
-
fats:
I just have to ask if you have documentation for that (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif) (mind you not that I doubt it, but simply havnt seen that before).
(And sorry to Raubvogel for turning down another sideway..)

lateral's at the 20 runs behind screen jukes 2 players breaks for sideline running hes at the 30-40-50 yard line into enemy territory cruising for the 40-30 "Ping" "wayward shot from the crowd" looks like he is gonna come up just a bit short. "-28-" Sound familiar in your Dora? <punt>

Correct, if I'm wrong, but didn't 109's (G-models?) had 2 separated cooling circuits with separated radiators ? Pilot was able to change the circuit with hand valve from cockpit ?
Anyone can confirm this ?
-
I did some testing on this and couldn't duplicate it. If your engine can still take damage on it's own separate from a cooling leak and that could cause it. When this happens have you noticed your temp gauge? Does it just shoot up into the red? A film of this happening would be very helpful if you have one.

Yes watching the temp gauge if you shut it off and on and manage it you can fly half a grid max, but you have to have some serious alt in order to do this. Taking a radiator hit in a FW the engine will cease running much quicker then say a P-51 which takes a radiator hit. Running full power in every plane I have been hit in, the FW dies rather quickly in comparison to the others modeled in here. One other note is Ground fire set to aim at engine/elevators only? I would say ack deaths around 80% of the time are hits to the elevators/engine. Other 20% is a combination of these 2 and other systems. In my other post in question is hte durability of the FW engine, noted for having armor cowlings, and its main design was to act as a shield for the pilot to bomber fire. Engines being hit multiple times losing multiple cylinders would still bring the pilot back. As it is now, engine hit equals certain death for a FW pilot. The F-8 seems to be made of balsa wood, another interesting fact, FW pilots when attacking bomber would flip there AC so the bottom was facing the gunners fire, having extra armor installed on the lower portion of the AC was vital for there escape. This was incorporated in the 190 A-8, and should be in the F-8 as well.

As a side note to the P51 flying forever after a coolant hit... well it should be able to. In RL, pilots were taught by North American to reduce throttle and RPMs and then there was another step. I dunno.. I can find it when I get home. There was a distinct smell of burning, but that was the paint burning off of the engine casing.
A few damaged P51s flew from Europe to England this way.

Films are always excellent ways to determine the problems. I will try to film everything from here on out in case this happens to me.
