Hi all,
According to the manual the Lancaster main wing uses NACA 23018. Does this mean
This aerofoil section is consistent from wingroot to wingtip? Or does the aerofoil
Change towards the wingtip?
Cheers

Hi Paul,
If you mean the RAF Museum reprint, yes.
Any info is appreciated.
Cheers

FWIW, I have seen a website that states that the outer wings tapered from 23018 to 23009, but no references are given. It was an old webpage which promised forthcoming updates. These updates never seemed to arrive, so I guess no further info is available from that source.
That site was the Incomplete Guide To Airfoil Usage.
Useful site, but as you say, shame it hasn’t been updated for a long time.
CeBro, when you say manual, I assume you mean A.P 2062 A & C (available as a reprint)?
Cheers

Cees, I have a number of Avro rib contour maps for the Lanc.
That won’t tell you at least directly what aerofoil sections were used.
But it should answer your question.
Of course the best quality and most readable ones are for the Lincoln.
But I’m hard pressed with a great deal of work on other matters at the moment.
If you need these, can you wait a couple of weeks or so?
