109 radiators and fuel tanks

[Schlowy]

Radiators:
I get shot in the radiator quite a bit when flying 109's.
All models of the 109 had two radiators, one under the left wing, one under the right. I'm guessing that they both did not get hit by the same bullet, so...

Did I actually get hit in the engine? Are the two radiators connected to the same pipes? or entirely separate fluid 'pipes' thru the engine?
 
Consider a 4 engine bomber, if one of thier engines gets a radiator hit, all of the engines don't suffer... almost the same thing? 2 radiators 1 bullet... sux!

Guessing that the 109 pilot close the flow to and from either side with a button or switch?
Can the 109's get some switches to open/close fluid flow to either radiator.
We need a close look at a 109 cockpit me thinks. Betcha the switches are in there somewhere.

-------------------------------------

Fuel tanks:
Self sealing tanks on 109s yes? When i get pinged up, maybe they do sometimes seal themselves and I never know it, I should be thankful for these unknown blessings if they actually happen... but why must it take the whole tank anyways? Did the puncturing bullet hit high or low in the tank?  If I fly upside down or somethin, ok, then it all goes out, but what about straight and level flying when only trying to get home?

Why must the whole (AND ONLY) 'main' tank drain out by one bullet that didn't neccessarily hit at the bottom fo the tank? sux!

---------------------------------------

Between fuel and radiators, me thinks I'm rtb'ing tooooo much.

Its the same with the P51 (not that it has two radiators). If you hit the cooler under the fuselage you can get both a rad hit and oil hit in real life. Im not sure if its that way in AH but I do know that no matter where the oil is hit the canopy gets oil on it.

Agreed. I think the issue though is that to model two seperate radiators and the different damage points would make the model far too complicated. Perhaps sometime soon we will be able to update it though?

I can't imagine they had 2 independent coolant systems.  That would require two water pumps (or some variation of), more weight, and not to mention there would be no way to cool both sides of the engine adequately with just one radiator.  I'm sure it's all one closed system that runs the coolant through the water pump, through the engine, through one radiator, then to the other, then back to the water pump.

[OOZ662]

I figure it'd be like the air system I have in my fish tank right now; A "2 unit" wide pipe headed out of the pump into a splitter that feeds two "1 unit" wide pipes...which would go through one of the radiators and merge back behind the pump into another "2 unit" wide pipe into the engine...or some other variation of that.

But, I'm sure one of the gurus will come along with the correct data soon enough.

The 109E had no way to isolate a damaged radiator. With the 109F, a valve was installed that could isolate the damaged radiator. Coarse that single radiator had to do twice the cooling work. Not sure if the valve was installed on later models.

I think it was but a long time ago there was a rumour that not all late 109s had the valves even if there was a place for them in the tubing and these had to be scavenged from older damaged planes that had still had them. Dunno if its true, though.

That's right.  The pilot could then, hopefully, fly home on reduced power.

C'mon already experts, wheres the 109 cockpit controls experts around here?
We're looking for a selector switch(es) for the two radiators.

[Anaxogoras]

I read today that the radiator shutoff switch was only sent out as field conversion kit for the 109F series.  They were rare enough that when a 109F crashed in friendly territory, crews would race to be the first to scavenge the shutoff switch from the wreckage.

I'll give you the exact quote about the cockpit controls after I eat dinner.

[Schlowy]

And did the two radiators use the same pipes and channels in the engine? or separate?

I have a flight and maintenance manual for the G-2. Here is what it says about the Cooling system.

If either one of the liquid coolers is hit, the damaged cooler must be disconnected from the system immediately by pulling the handles on the left and right in the forward part of the cockpit depending on which of the radiators was damaged. Basically keeps you from loosing all the fluid out the damaged radiator by isolating it from the system.

Beau32, yer my new bestest friend!  Pls put a source!  scan it in to your puter and post!

109's are getting new radiator controls!  WHOOO HOOO 
I hear a rumbling of angry platinum and gold members! Stampeed! 

And to think that formerly banned 'evil schlowy' might get a 109 change for the better, I'll get the iron cross!

[Schlowy]

Implementation, upon the ghod's approval 

Maybe instead of a switch,
109's get a 'Left Radiator' and 'Right Radiator' instead of a 'Radiator.'

You sound like a marxist... Do you really think there is a "class-war" going on between people with different numbers of posts?

I will be ecstatic if we get this change, but that one statement just really made me wonder about you...
