Flying to the Limit by Peter Caygill

 

The following information pertains to Hellcat I FN322 of the Fleet Air Arm.

     "The Handling trials were carried out at a take-off weight of 12,140 lb."

" Acceleration was high and the lift-off speed was around 80-85 mph IAS."

     "At higher speeds, the controls tended to become heavy on early aircraft,

although this problem was addressed on the Hellcat II with the introduction of

spring-tab ailerons. These produced a dramatic improvement in lateral control."

     "A number of out-of-trim dives were made at full and one-third throttle, up

to the limiting speed of 460 mph IAS. The longitudinal control characteristics

were satisfactory, although the push force to hold the aircraft in the dive was

large, and the pull on recovery was of a similar magnitude. At speeds above

300 mph IAS, the ailerons were considered to be too heavy for a fighter; and

by the time that 350 mph IAS was reached, they were almost immovable. The

rudder was fairly heavy, but was effective in producing yaw up to the limiting

speed.

     The Hellcat was looped with the engine operation at climbing power (2550

rpm, 44"Hg), starting at an initial speed of 350 mph IAS and applying an estimated

4g. At the top of the loop, the speed had reduced to around 120 mph IAS, before

it increased again to 240 mph IAS in the recovery. The stick forces involved were

not excessive. Rolling performance was best at speeds between 180-230 mph

IAS, being approximately 60 degrees per second. At higher speeds, the ailerons

were too heavy for good manoeuvrablility. The initial force required to apply

full aileron was large, but once the roll had been started the force needed to

maintain full deflection reduced."

 

     "Performance trials were carried out at the same time as the handling

assessment and involved FN322. Readings could only be made up to

28,000 ft, due to internal sparking in the magnetos when the aircraft was

flown at higher altitudes. The maximum rate of climb in main Super-

charger gear was 2260 ft./min at 5400 ft. and 20,000 ft. was reached in

ten minutes. The recommended height to change supercharger gear was

9200 ft. The full results were as follows (* and ** denote full throttle heights)."

 

Altitude / Speed / Climb / time to altitude

Feet       /MPH   / FPM   / Minutes

  2000     315*    2260      0.9

  4000     314     2260      1.8

  5400                2260*     2.4

  6000     314    

  8000     323     2000      3.6

10000     332     1880      4.65

14000     350     1880      6.75

18000                1880      8.9

18700     371**

20000     370                  10.0    

20500                1880**  10.25

22000     369

24000     367     1400     13.35

28000                  840     16.0

 

Calculations from the information given:

Service Ceiling: 33,280 ft.

Wing Loading (12,140 lb./334 sq. ft.): 36.35 lb./sq. ft. 

Power Loading (12,140 lb./2000 hp.): 6.070
