Airfoil Data
RAE2822

The RAE 2822 AIRFOIL is a thin 6.3% chord-thickness airfoil with a maximum camber of 3.1% at 43% chord, suited to high-speed UAVs, sailplane tip sections, and propeller blade design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -3.1°.

Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 53 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The slim profile minimises pressure drag at higher speeds but leaves limited spar depth for structural integration.

Designers evaluating the RAE2822 typically compare it against profiles of similar thickness: RAE6-9CK AIRFOIL, NACA 0010-34 a=0.8 c(li)=0.2, KC-135 Winglet (supercritical Whitcomb), NACA 64A210, BOEING 707 .99 SPAN AIRFOIL. The AH 94-145 is another reference profile frequently considered alongside it.
