Pilot's Handbook of Flight Operating Instructions (AN 01-45HA-1)
USN: F4U-1, F4U-1C, F4U-1D, F3A-1, F3A-1D, FG-1, FG-1D
FAA: Corsair I-IV
R-2800-8W:
War Emergency 2,700/59.5" 5min
Take-off 2,700/54" 5min
Military 2,700/53" 30min **
Normal 2,550/49.5" continuous
Max Cruise 2,150/34" continuous
edit: ** I'm dubious about this 30min, the scan isnt very clear but it does look like 30min. however, elsewhere in the manual WEP is referred to as "2700rpm (five minutes)".
later - "The rpm's and manifold pressures at a given supercharger control setting for take-off, military, and war emergency operation must never be exceeded;
the five-minute time limit for each of these conditions must never be exceeded."
This is also consistent with the R-2800-21 used in P-47B/C/D/G - 2550rpm is max continuous, 2700rpm is limited to 5mins.
so ... the AH F4U-1 should look like this:
WEP 2700/53"
Military Power 2550/49.5"
Normal Power 2550/44"
Max Cruise 2150/34"... the AH F4U-1A/C/D should look like this:
WEP 2700/60"
Military Power 2550/49.5"
Normal Power 2550/44"
Max Cruise 2150/34"... but the current AH F4U-1/1A/C/D all look like this:
WEP 2700/57.5"
Military Power 2700/54"
Normal Power 2550/44"
Max Cruise 2150/36"
