Propeller Performance: APC thin electric D8 P6
0.5 to 0.9
Propeller thrust coefficient (CT), power coefficient (CP), and propulsive efficiency (eta) versus advance ratio J for standard propeller families: APC sport, APC thin electric, NACA Clark Y general aviation, UIUC DA4002 benchmark, and generic variable-pitch. Covers UAV/hobby propellers (8–18 inch) and general aviation (72–74 inch). Data sourced from APC published performance files, UIUC Propeller Database (Brandt & Selig), and NACA Report 640.
