I'm looking for the N71 airfoil for a scale project but can't find it anywhere. I found it in an old NASA technical report but I've lost the link. Please can anyone help?

Thanks!
Jon

It might be easier to find the airfoil data by searching on the aircraft itself, what aircraft. ?

Is it the Avro Baby ?

I found this if it helps - http://www.eaa.org/bitsandpieces/art...11-02_baby.asp

The section towards the bottom mentions a Baby built from original drawings at 1:1, he used the RAF 15 airfoil, (though that may not be exactly original, it could depend on just how scale you want).

It's the Plumb BGP-1, a one off biplane. I am doing a Baby too so thanks for the link!

According to this page http://www.ae.illinois.edu/m-selig/ads/aircraft.html the same wing section was used on the "Republic EP-1 Model 100". According to this other page http://www.avrosys.nu/aircraft/jakt/109J9.htm the Republic EP-1 was an export version (EP = Export Pursuit) of the Seversky Republic P35 (also confirmed on http://en.wikipedia.org/wiki/Seversky_P-35 ). I am not sure about the specific model 100, but I doubt that the wing section would have been much different between versions. On the page I linked first the wing section for both the Seversky P-35 and Seversky EP-1 is given as Seversky S-3, which might be a bit easier to track down. It's the same wing section as the P-47 Thunderbolt and several other Seversky fighters, all derived from the Seversky S-3 Racer wing section.
[edit] there's a picture of the section in this thread, along with a close naca one: http://www.rcgroups.com/forums/showt...1118939&page=4
[edit 2] I am not sure how recent is this page, but it offers you a form to contact Barry Plumb, the designer and owner of the plane you are trying to reproduce: http://www.steenaero.com/biplane_lore.cfm
[edit 3] Or you could try to contact him through the Light Aircraft Association http://www.lightaircraftassociation....arryPlumb.html , where he serves as Director and Chairman of LAA's Engineering Committee. My guess is that sending an email to the address engineering@laa.uk.com (from http://www.lightaircraftassociation....ontactLAA.html) is likely to come to his attention.
[edit 4] or via his email address at the Manchester Metropolitan University b.plumb@mmu.ac.uk , where he is Professor Emeritus ( I imagine in Electrical Engineering) and according to this page he is currently chairman of the Military Education Committee (MEC) http://www.mmu.ac.uk/mec/
[edit 5] or through the The University of Manchester Staff Golfing Society ... nah, this is getting so easy it's no fun anymore

Thanks Brandano. Barry has sent me the drawings for the aircraft already I was just looking for a small scaleable drawing. The idea was to plot a slightly thinner version as the model is only peanut sized. That one you linked to looks right, thanks.
