Airfoil Data
TEMPEST1

The HAWKER TEMPEST 37.5% SEMISPAN AIRFOIL is a 8.3% chord-thickness airfoil with a maximum camber of 4.1% at 38% chord, suited to general-aviation and UAV wing design. At zero angle of attack the cambered geometry generates positive lift, giving an estimated zero-lift angle of -4.1°.

Thin airfoil theory predicts a stall angle near 11.8° and a peak lift-to-drag ratio around 59 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 TEMPEST1 typically compare it against profiles of similar thickness: NACA 64(1)-212 MOD A, EPPLER 479 AIRFOIL, GOE 133 (MVA H.11) AIRFOIL, ONERA OA212 AIRFOIL, GOE 373 AIRFOIL. The RAE 102 AIRFOIL is another reference profile frequently considered alongside it.
