I would like to know if anyone has data on the fuel capacity of various Yak-9 variants, particularly interested in Yak-9T, D, DD, U and P variants. Some of the fuel loads are on the Wikipedia article but cited no sources.
As title. Requesting info on the two airplanes' top speeds at various altitudes, preferably in the form of a speed-altitude graph such as the one linked.
The comparison will be made at 25000ft, the altitude of the B-17 raids.
Speed at 25000ft:
P-47D with -63 or -59 engine (cleared for 70" on June 24, 1944): 439 miles true speed http://www.wwiiaircraftperformance.org/p-47/p47d-44-1-level.jpg
P-51 with -7 engine (cleared for 75" on April 29...
The P-47 had a substantially higher stall speed, and its top speed in IAS at sea level is three times the stall speed, which means it can pull 9G at sea level without stalling. If you bring it higher, the top speed in IAS drops even though that in TAS increases, and pulling more than 9G becomes...
Take it to who wrote the stuff. Now, who wrote it? You still haven't told me yet. Then, if you don't believe my claim the P-47 was faster than P-51 at most altitudes, go look at the speed vs altitude graph of the P-47 and of the P-51. The P-51 outruns the P-47 around its first speed supercharger...
The value of 13.5G is completely meaningless, the F6F's top speed in indicated airspeed is not sufficient to generate a turn that reaches 13.5G. No P-47 was recorded breaking up in flight, neither was any F6F, as no pilot is willing or able to pull more than 9G. In the P-47 it is impossible to...
There is a discrepancy with the reports available on wwiiaircraftperformance.org, I don't know what happened there. Both the USAAF and NACA performed testings and charted their high speeds in terms of True Airspeed instead of Indicated Airspeed/Calibrated Airspeed, which means it is more...
If you say the P-47 after September 1944 was not faster at all altitudes, at what altitude can the F6F outrun the P-47?
Second, how do you actually reach 13.5G in an F6F?
Third, show me all your sources. All the factual claims I made are true and verifiable on wwiiaircraftperformance.org which...
Because they used the same engine, if one is faster at a certain altitude, then it is faster at all altitudes. Testings done by NACA also used true airspeeds instead of what is read from the airspeed indicator (they either corrected that value for instrumentation error and converted it to true...
The comparison is pointless since the Spitfire and Tempest had completely different roles. The Tempest is a low-altitude air-superiority fighter, whereas the Spitfire is a high-altitude interceptor. The Spitfire XIV is trash down low: near its top speed on the deck it can hardly roll at all...
