Niklas,

Don't disappear now.

ok here i am - i just needed a little bit time to study your documents.

ahhhaa Cd0 = 0,02 - now this sounds a bit more realistc ....

when "Flugzeugmuster" is line 1, then drag is line 10 (Schnellflug = fast flight) and 11 (Steigflugflug = climb). It´s dragarea (cw0F = cd0*wingarea , wingarea in m^2). K in the same line is the factor for induced drag (k*cl^2). K also includes wingarea (i.e 18,9 m^2 for the A-8).

Thanks Niklas,

I hardly ever agree with you, but you have some great documents.

F4UDOA,
Somewhere on this BBs you asked where I obtained the roll data for my chart. The answer is: The NACA server. Go to:
http://naca.larc.nasa.gov/reports/1947/naca-report-868/ and download a .pdf copy of report #868, Summary of Lateral-Control Research. The aircraft defined are as follows:

Fw-190A (I believe this was a captured A-4)
Typhoon
Spitfire (standard wing)
Spitfire (clipped wing)
F4F-3
F6F-3
P-39D
P-47C
A6M
XP-51
P-51B
P-63A
P-40F

The P-38L is not found on that report, but is found in a test report authored by Ben Kelsey. I have a portion of this report and will post the data tonight, after I dig it from my files.

My regards,

Widewing

I have received permission from the owner of this document to post limited portions of it here.

P-38L roll data follows:

My regards,

Widewing

Great document Widewing! Looks like wing twisting becomes a factor over 300 mph as the roll rate starts to level off.

Just digging this up again ... does anybody have any CLmax data or stall data for the 109? How about for the Ki-84? Thanks in advance.
