Airfoil Data
DGA1182

The D.G.A. 1182 is a thin 4.3% chord-thickness airfoil with a maximum camber of 2.1% at 40% 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 -2.1°.

Thin airfoil theory predicts a stall angle near 12.0° and a peak lift-to-drag ratio around 47 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 DGA1182 typically compare it against profiles of similar thickness: AG47c -03f, SIKORSKY SSC-A07 AIRFOIL, HT23, NASA/AMES A-02 AIRFOIL, NASA/AMES 63A108 MOD C AIRFOIL. The EH 1.5/9.0 is another reference profile frequently considered alongside it.
