Pyro, Question about fuel consumption rates
« on: June 14, 2002, 11:38:24 AM »
Pyro,

I was prompted by another thread to do this so don't think I was sitting up all night worrying about it but......

I tested the F4U-1 fuel consumption offline at Mil power and at max cruise. What I found is that the fuel burn rate does not change much with a change in MAP.

From the F4U-1 manual

Mil power sea level GPH(Gallons Per Hour)=290
Mil Power sea level Map = 52.5"

Max Cruise Sea Level GPH = 83
Max Cruise  Sea Level MAP = 34"

This is a fuel consumption of 3.5 times less in max cruise than MIL power. However offline with a fuel multiplier of 10 a 25% fuel load.

Mil power = 2.10 minutes
Max Cruise= 3.0 minutes

40% differance and it should be 3.5 times more.

Is this not modeled in AH?

I know it is a big hairy nit to pick but I just thought I would ask;)
