RAF30MD
RAF 30 MOD AIRFOIL
Wing Geometry Simulator
The RAF 30 MOD AIRFOIL is a thin 3.8% chord-thickness airfoil with a maximum camber of 1.9% at 30% 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 -1.9°.
Thin airfoil theory predicts a stall angle near 12.0° and a peak lift-to-drag ratio around 46 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 RAF30MD typically compare it against profiles of similar thickness: S8021 (7.6%), S8023 (7.6%), ONERA OA206 AIRFOIL, BOEING VERTOL V13006-.7 AIRFOIL, AG47ct -02f rot.. The GOE 398 AIRFOIL is another reference profile frequently considered alongside it.
