Airfoil Data
BQM34

The RYAN BQM-34 FIREBEE WING AIRFOIL is a thin 5.0% chord-thickness airfoil with a maximum camber of 2.5% at 33% 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 12.0° 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 BQM34 typically compare it against profiles of similar thickness: HQ 1.0/8 AIRFOIL, NACA 1408, NPL AIRFOIL FROM ARC CP 1372, HAM-STD HS1-404 AIRFOIL, JX-GS-06. The NACA 0012-34 is another reference profile frequently considered alongside it.
