Hi Keith,
Have to say I have never seen a name for the aerofoil section and have just had a look at the Aircrew Manuals and (not surprisingly) there is no name there. Lots of other details such as sweep, area, etc...
A place to have a look may be the Lance Cole VC10 book, but as far as I was aware the VC10 was pretty much the first airliner to have a specifically designed wing which did not just pull a wing section from a catalogue...
Sorry, not much help, but I would be very interested in what you may find out...
Tonks
PS... Hope we see some pics of the model!!!
