RONCZ R1145MS AIRFOIL
Wing Geometry Simulator
The RONCZ R1145MS AIRFOIL is a 13.7% chord-thickness airfoil with a maximum camber of 6.8% at 40% 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 -6.8°.
Thin airfoil theory predicts a stall angle near 11.0° and a peak lift-to-drag ratio around 71 at typical UAV and light-aircraft Reynolds numbers — useful benchmarks before running a full XFOIL or NeuralFoil polar. The 14% thickness provides structural depth for main-spar placement without excessive drag penalty at moderate speeds.
The R1145MS appears in the wing design of at least 8 documented aircraft, including designs from Co-Z and Cosy. Its proven track record across canard designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the R1145MS typically compare it against profiles of similar thickness: RONCZ R1145MS MAIN ELEMENT, FX 66-S-196 V1 AIRFOIL, GOE 630 AIRFOIL, GOE 234 (MVA CA5) AIRFOIL, Dayton-Wright T-1. The RONCZ R1145MS MAIN ELEMENT is another reference profile frequently considered alongside it.
