A330 L/D & SFC
Hello guys, I need an estimation about the L/D ratio and SFC of the A330 at its typical cruyse speed (M=0.82).
I need them because Im trying to estimate the Breguet Range paramater:
K=(Vcruise/SFC)*(L/D)
-i would really appreciate some help

RarraMan,
The specific range of an A330 at M.82, 200 tons, cg=37%, FL350, ISA is 80 NM/1000 kg of fuel. You should be able to calculate the Breguet range parameter from that.

The Breguet Range paramater: K=(Vcruise/SFC)*(L/D)/g
may be written as: K = (V/F)*(W/g), where -
V/F = specific air range in NM/kg of fuel
W/g = mass of the airplane in kg
so for the example I gave:
K = 80*200 = 16.000 NM
may be written as: K = (V/F)*(W/g), where -
V/F = specific air range in NM/kg of fuel
W/g = mass of the airplane in kg
so for the example I gave:
K = 80*200 = 16.000 NM
