UIUC NR640 (research design)
9 in class · air · measured geometry
UIUC-designed research propeller on the NR640 section (Deters, Ananda & Selig, AIAA 2014-2151): tapered planform peaking at 0.5R with the published design twist, wind-tunnel tested. Geometry from the published design table; sections here are NACA-derived approximations of the NR640 airfoil.
