p-24
the Fairey P24 was a nice concept but being developed at Fairey meant it was short of muscle in the manpower department.
I have a spec for the moderately superchrged version which reads
rated power: 1,500 bhp @ 2,600 rpm
max Take off power: 1,540 bhp @ 2,300 rpm
rated altitude: 9,500 feet
normal rpm: 2,600 rpm not normally exceeded for continuous cruising at any altitude.
max permissible rpm: 3,000 not to be used for more 5 minutes consecutive running.
diving rpm: 3,150 rpm at not more than 1/3rd throttle opening.
max permissible boost: +3 lbs/sq in.(for not more than 5 mins)
rated boost: +2lbs/sq in.
fuel: DTD 230 [ I think is 87 octane]
bore: 5.25"
stroke: 6.0"
capacity: 3118 cu. in (51 litre)
The flight engine rating data is:
rated altitude: 10,000ft
rated boost: +1/2 lb/sq in
max permissible boost: +3 lb/sq in
normal rpm: 2,400
take off rpm: 2,
bhp @ 2,400 rpm @ 10,000 ft - 1,275
bhp @ 2,750 rpm @ 10,000 ft - 1,425
bhp @ 2,130 rpm @ +3 lb/sq in boost - 1,300
