Airfoil Data
MRC16-85

The MRC16-85 is a 9.0% chord-thickness airfoil with a maximum camber of 4.5% at 36% 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 -4.5°.

Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 61 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 MRC16-85 typically compare it against profiles of similar thickness: GOE 547 AIRFOIL, S4320, AS5046 (16%) | Ref: http://www.krnet.org/as504x/ [original link: http://amber.aae.uiuc.edu/~ashok/kr2/airfoils/tests/], NASA SC(2)-0518 AIRFOIL, SD7034. The HOBIE is another reference profile frequently considered alongside it.
