HORSTMANN AND QUAST HQ-17/14.38 AIRFOIL (MEASURED)
Wing Geometry Simulator
The HORSTMANN AND QUAST HQ-17/14.38 AIRFOIL (MEASURED) is a 12.1% chord-thickness airfoil with a maximum camber of 6.1% at 44% chord, suited to high-lift UAV wings, RC sailplanes, and low-Reynolds-number slow-flyers. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -6.1°.
Thin airfoil theory predicts a stall angle near 11.6° and a peak lift-to-drag ratio around 69 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 12% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.
The HQ17 appears in the wing design of at least 1 documented aircraft — notably by Binder. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the HQ17 typically compare it against profiles of similar thickness: GOE 332 (PFALZ 61) AIRFOIL, WORTMANN FX 77-W-153 AIRFOIL, GOE 621 AIRFOIL, GOE 612 AIRFOIL, EPPLER 399 AIRFOIL. The HQ 3.5/13 AIRFOIL is another reference profile frequently considered alongside it.
