No, it is not symmetrical. But they used symmetrical sections for wind tunnel tests, so it probably uses one of these symmetrical thickness distributions, wrapped around a camber line. It is mildly laminar flow at best, but still quite conservative.

William Green's US Army Airforce Fighters, part 2, should have a cutaway, but I can't confirm yet. I took that book out of the library, probably 30 years ago, memory is not 100%...
The Encyclopedia of World Aircraft, while not a definitive source, lists the "initial" climb rate at 2697 ft/min ( 822 m/min ), weights of 6305 lbs ( 2860 kg ) empty and max takeoff 8236 lbs ( 3736 kg ). Max speed of 371 mph ( 598 km/h ) @ 6000 m ( 19685 ft ). What weight and power was used to...
Based on those coordinates, the Mitsubishi 118 is a NACA 250 mean line, with max camber at 25% chord, instead of 15% chord, as with 230 mean line ( see NACA report 537 ). The camber is reduced to 2%, from 2.3% for the standard 250 mean line ( the value of k is about 2.858 vs the standard value...
I'm gonna throw another curveball at you, hehe
Both Maru Mechanic 45 and "Japanese Army Fighters, Design with Precision" both agree on Ki-43-IIIa, in that the Ha-35-32 engine is used and the latter source cites the maintenance and flight manuals as sources. Data for the model 32 engine is 1150...
the column was tilted 11 deg towards the pilot in the "neutral" position. For aileron control, it tilted 41 deg to either side of neutral. that's all I got, from the MkV manual
TAIC engine data is Japanese data, translated, with the exception of WEP estimates. Given boost and RPM figures, everything makes sense, except that power at 3400 m is probably closer to 930 US hp ( 940 metric HP ). The Sakae 12 is not the same, as the supercharger ratio is different ( 7.53 vs...
Kotelnikov's book, "Russian Piston Aero Engines", gives 146/165, but then he says the displacement is 35.7 L. It doesn't make sense that if they were trying to improve on previous versions, that they would make it smaller, even if it had higher compression.
