Oswald's efficiency factor for DC-10-30
Does anyone have any sound references for the Oswald Efficiency Factor of the DC-10-30? I've seen 'e' quoted as .83 in the past but I would like to confirm this. Setting this value correct in my flight dynamics will greatly influence the induced drag of the aircraft.
As of now I have the e set at .879, but I think that's being a bit generous. Can anyone give me some references for confirmation? Thanks!
