Test pilot Tom Bellinger stated flatly that his no flights ever exceeded 500 mph with the dash 13 engine. With the planned but never installed dash 19 engine rated at 3,650 HP at 25,000 ft (3,000 HP at military power) a top speed of 504 mph at approximately 25,000 feet was expected. Planned further development of the dash 19 engine was expected to yield approximately 4,000 hp and a speed of 540 mph at 25,000 ft.
altitudes and perhaps the difference between straight line speed and lap times?I find this surprising as the air racing version had its wings clipped & all excess naval equipment removed & yet there's only an 8 mph gainedzz
I agree that the Corsair did indeed, pick up over 40 mph but as you noted, that's at Fl 160. The altitude at Stead is 5,029, which made this airfield ideal for air racing. I was comparing the two Super Corsairs under similar conditions.altitudes and perhaps the difference between straight line speed and lap times?
Corsairs picked up around 40+ mph going from sea level to 16,000ft.
The Air Races in the 1940s were at under 1000ft.
Times from the 2006-2008 races in Reno are at around 5000ft and summer desert temperatures.
Result of the combination of rose-tinted glasses carried by the people itching to represent the XP-72 as a non plus ultra fighter, and the actual, additional 400+- HP worth of exhaust thrust?The XP-72 with her "early" b-series R-4360 reaches full throttle height and maximum speed at approximately 25.000ft. But the P-47D with WEP rating reaches the same power at same height. Where is XP-72 speed advantage of almost 50 mph coming from??
The F2G didn't have the water injection of the XF8B, but if it had, would it have been faster? Was the XF8B a "jack of all trades, master of none" as a "5 in 1" fighter with its own internal bomb-bay?
Was there any advantage in having a massive R-4360 powered fighter when compared to the other alternatives coming online in 1945 (P-51H, XP-47H, F8F, etc).
Where do you got this numbers from?Powerplant
XF8B - 3,600 hp XR-4360-10
XP-72 - 3,500 hp R-4360-13
The second tab has charts showing that the F2G excelled at low altitude.
