Gentlemen - thank you. I will sign them. Corsning you may use what I posted.
PLEASE do!I'll do a search if you'd like
The new book will be "Long Range Escort - How the Bastard Stepchild Mustang saved the 8th AF" or words to that effect.
I have toyed with notion of inserting F4U-1 as a 'what if", but it only makes sense if I can get valid cruise data to develop Combat radius comparing to ETO AAF boundary conditions for Combat Radius. Opinion, it would have been at least as effective as the P-47C because it had 56 more gallons of internal fuel, but it has to be compared at 25,000 feet - not USN profiles of 15,000 feet.
It sounds like a most interesting book.
The big question on the F4U-1 is what the performance was like between 25,000 and 30,000ft as it's engine was loosing power as altitude increased. Engine was down to 1450hp at 25,000ft Military power and a bit over 1200hp at 30,000ft also military power.
I believe but could be wrong, that the Corsair had more drag than the P-47 and the engine charts do show an advantage for the P-47. Like 1625hp max continuous being available at 25,000ft (or below) at 2550rpm and 42in manifold pressure while the F4U-1 to get 1625hp max continuous at below 24,000ft needs the same 3550rpm but needs 49.5in manifold pressure from low gear of the auxiliary supercharger. The extra 7.5in ( 3 3/4lbs) pressure making the power needed to drive the aux supercharger?
Max lean ratings seem to show as much as a 10% advantage for the P-47 in HP made per gallon of fuel burned?
While the internal 361 gallons of the F4U (wing tanks protected by CO2?) so a roughly 20% advantage over the early P-47 305 gallons if the F4U needs even 10-15% more fuel to fly the same speed/altitude than any advantage disappears pretty quick. Using a Navy plane for less than a 10% increase in range? perhaps only 0-5% increase?
The new book will be "Long Range Escort - How the Bastard Stepchild Mustang saved the 8th AF" or words to that effect.
