TSAGI_R3A
TsAGI R-3a (12%)
Wing Geometry Simulator
The TsAGI R-3a (12%) is a 9.5% chord-thickness airfoil with a maximum camber of 4.8% at 23% 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 -4.8°.
Thin airfoil theory predicts a stall angle near 11.7° and a peak lift-to-drag ratio around 62 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.
The TSAGI_R3A appears in the wing design of at least 18 documented aircraft, including designs from Mil and Emelyanov. Its proven track record across conventional and rotorcraft designs makes it one of the more field-validated profiles in the UIUC database.
Designers evaluating the TSAGI_R3A typically compare it against profiles of similar thickness: NACA 6-H-10 AIRFOIL, MRC20-846, lrn1007, GOE 450 AIRFOIL, FAUVEL 14% AIRFOIL. The S8035 for RC aerobatic 14% thick is another reference profile frequently considered alongside it.
