Here's that BF 109E vs Spitfire turn radius info I mentioned a while ago...
It's in a Royal Aeronautical Society publication, The Aeronautical Journal Volume 104 Number 1032 February 2000
Here is the original numbers calculated by Mason and featured in Len Deightons Fighter I believe.
This table was calculated for a sustained turn at a speed of 300mph, at 10,000ft and 50% fuel.
CL = coefficient of lift.
w = wingloading, lb/ft^2
G = "available G" - a term used by Mason, dunno it's meaning exactly
Aircraft - CL - w - G - radius
Hurricane I 1.0 22 7.5 800ft
Spitfire I 1.0 24 7.0 880ft
Bf 109E-3 1.0 25 8.1 750ft
Bf 110C-4 1.0 32 5.2 1210ft
As can be seen, the wingloading of the Bf 109E is rather incorrect, due to Mason using an incorrect weight in his calculations.
The turn radii were recalculated at what was determined to be the maximum sustainable corner speed by calculation of CD0 and other various factors. Have to read the full article to get all that info, I have only copied the final table:
CL = maximum coeff. of lift (CLmax)
n = load factor = lift/weight
Vs* = sustained corner speed, m/s
Aircraft - CL - n - Vs* - radius
Hurricane I 1.35 2.8 72.0 202m
Spitfire I 1.35 2.74 72.2 209m
Bf 109E-3 1.4 2.67 79.6 260m
Bf 110C-4 1.4 2.64 78.4 256m
