Bf-109 radiator management

[Cpt_Fracassa]

Can somebody explain to me this sentence?

 

 

8. Bf 109 F-4 and G-2 thermal balance corrected using 'African' reference: larger and larger radiator opening yields less and less cooling increase, which leads to necessity of opening radiator more at higher temperatures and during climb.

 

larger radiator opening, with more airflow I suppose, yields less cooling capacity? ...

I think should be opposite: more airflow. more cooling ...

 

Than i wonder:

 

1. data taken on "African reference" ... but we are flying russian front.

2. I think flying squadrons had their staff of mechanics following them on the airfields, providing adaptations to wistand climate and other technical problems ... so why should they produce less efficent cooling systems when the opposite is needed?

 

Thanks eventually.

I don't know about the "African" thing, but I think Han intended that increment isn't linear. I.E. You would need more than double radiator opening to get double the cooling effect. Make sense, as You add more airflow, but not more radiant mass.

 

Moreover, the devs are russian, and we have a sort of language barrier, more so when both side have to communicate by a foreign language.

 

Regarding the ground crew, there is a limit at what they can do. How would You boost the cooling capacity over the spec, on the field?

In winter, You close the vents (remember old FIAT truck with round chrome radiator grille? In winter they always had a blanket over it), but in summer? Yes, a better water pump, maybe... If available.

 

Fazer.

You wrote it, in summer you can add more radiant mass, or take out some filter... It was their job. And more efficient altitude changing temperature. At any altitude from ground level, temperature start to drop significantly, but it seems not coded. As it is now, the radiator efficiency seems halved, while soviet planes never get "coocked" a little.
