XI. Turning Performance:
Altitude/Direction/IAS/Radius/Time/RPM/AMP
1969'/Left/205 m.p.h./307.4'/10.8/2700/37.8
1969'/Right/205 m.p.h./301.5'/11.0/2700/37.8
Note: Turns are executed without difficulty but the ailerons get heavy with increased speed.
Wonder if anyone has any drawings of the cowl/nose sections for the ki43 IIb or III, I would be very thankful for any such information or drawings.
Also does anyone have a source or even be kind enough to provide some drawings for the Mitsubishi A6M5 cowl?
Something is fishy here. The formula for the radius of a level turn is: R = V^2 / (g * tangent[bank angle]), and you can get the bank angle from the arc cosine of (1/ g-force).
At 205 mph and 2.92 g, you complete a 180° turn in 10.7 seconds with a radius of 1,024 feet at 17° per second turn rate.
AT 205 mph and 5.7 g, you could complete the 180° turn in 5.2 seconds with a radius of 501 feet at 34° per second turn rate ... IF you had the power and an airfoil that could DO it. I cannot think of ANY WWII plane that can turn at 34° per second, so that sounds pretty much like pie in the sky to me. I am quite suspicious of values above around 20° - 25° per second even for a maneuverable Japanese type and I don't believe any WWII fighters could sustain much more than 4 g's in a level 180° turn ... not that the wing couldn't do it, but they didn't have the excess power to stay level at more than around 4 g's. Might be wrong in this, but would be glad to discuss it.
I work in SAE units (mph and feet), but working in metric units is no trouble if it helps the discussion.
