ACResearcher said:Curtiss never named this aircraft. However, a crated CW-21 had DEMON sprayed on it, short for DEMONSTRATOR, that was being shipped to a recipient that I cannot recall off the top of my head.
In the same manner so many other "facts" have been distributed (like all Consolidated B-24Js had Consolidated/Southern Aircraft nose turrets and all Hs the Emerson - half correct), so has this misidentification become Truth.

and the related SNC-1 version. Here is a original Curtiss archives photo showing the AT-9 production line, right next to CW-22/SNC-1?.tallguy said:The AT-9 used the CW-21/22 wings as the outer panels and I believe the tail as well.
Wing loading and the air foil ?
CW-21....looks like a 23015 ?Wing loading and the air foil ?
If you're asking about the CW-25 (AT-9) Jeep's airfoil, it was NACA 23015.9 (at the wing root) and NACA 4410 (at the tips) according to David Lednicer's Airfoils of U S and Canadian Aircraft.
If its the CW-21 that you're after, the Demon used an inhouse Curtiss CW-19 Special' airfoil. Same source: -- http://www.aerofiles.com/airfoils.html
Oddly, the wing loadings for the CW-21 and CW-25 were identical - 25.83 lb/sq.ft / 126 kg/sq.m

It is much bigger than Me-109.Cute little plane.
It's detailed in the Putname "Curtiss" book.
