How to close radiators on the FW 190 D9?

[Sunde]

Hey gents, i used to be able to use the inlet/outlet cowl shutter control to close the rads on the D9, but now they have no effect.

 Apparently i need to change the temperature of some "thermostat" now instead? I can find no control mapping for thermostat however.

Help a man out!

I never fully understood it. It is automatic but you can move the threshold (?) with the thermostat controls.

 

I thought those were the same controls as radiators OR outlet cowls but I'm not near the game to confirm.

Would appear that "normal" water radiator bindings did the trick!
 Just confused as in the specifications i read it as being a separate binding, all good

Just keep the water radiator closed - that's the most efficient setting.

The thermostat sets the temperature for cooling system. AFAIR it should operate at about 100 degrees centigrades. If you go higher, then you have better cooling efficiency, but higher pressure in the system. This means, down low, you can force higher temps than up there, where reducing ambient pressure will further increase your cooling pressure. If you have overpressure, then the system gets vented and you are basically leaking coolant. Also, the engine doesn‘t like being really hot, especially when made from unsuitable materials (Sparmaterial). In the game, I so far saw little punishment from running it hot, so there you go. Setting coolant hot will act kind of like „closing rads“.

 

I don‘t have the actual PN of the D9 at hand now for more specifics, but in the game I think you can do as Luke said.

Some planes like the late spitfires and the 109s have auto radiators controls but there a way to force them full open. Is that modeled in the game? Im not at home do I cant check now that I think of it.

Yes, according to the in-game spec page, the rated coolant temperature is 100 degrees. If you then set the radiator flaps to fully closed, the thermostat will work automatically to maintain 100 degrees.

Yes

Are you referring to the oil or the water radiator? I was under the impression that for the Spitfire and the 109 you could only control the water radiator manually, while the oil radiator was always automatic.

Oil radiator is automatic in all 109s (starting with the F series). Manual coolant radiator override starts with the F-2, where it is 100 % open when in manual mode. After that, they can be set to any position. 

 

Spitfire IX and XIV has a manual coolant radiator override, but in reality this was just a test switch to ensure the system was working properly.

To be clear, you are referring to water coolant here, right?

So there's absolutely no way to control the oil rad with the 109 starting from F. Damn. I sometimes get the 'watch the oil temperature' message in the 109 despite being at combat power for only a couple of minutes. 

 

Was the oil radiator of the 109 so innefficient that, during summer, you could only use combat power a couple of minutes before your oil temp went above safe levels?

u must be going too slow too long time for oil to overheat. never had such an issue flying 109s myself.

I get this message all the time in the F2, even when flying >450kph and at cruise power. It never really bothers me, the temperature never rises much further. It seems the automatic cooler only really starts cooling when it reaches the "watch out" threshold.

I personally prefer to have open during cruise - and as soon as I spot enemies close it. 
 

This way the automatic mode can hold the rated temperature for longer with lower settings and thusly reducing drag a little during combat for the price of having higher drag during cruise. 
 

But it’s just very slight an advantage.
