Airfoil Data
LWK79100

The LWK 79-100 is a thin 5.0% chord-thickness airfoil with a maximum camber of 2.5% at 28% 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 -2.5°.

Thin airfoil theory predicts a stall angle near 11.9° and a peak lift-to-drag ratio around 49 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 LWK79100 typically compare it against profiles of similar thickness: RAE 101 AIRFOIL, RAE 100 AIRFOIL, NACA 64A-010 10.0%, RAE 103 AIRFOIL, NACA 63A010 AIRFOIL. The NACA 747A415 is another reference profile frequently considered alongside it.
