USA-35B AIRFOIL at a glance
At a Reynolds number of 1,000,000 the USA-35B AIRFOIL reaches a maximum lift coefficient of 1.72 at 14.5° angle of attack, a best lift-to-drag ratio of 129 at Cl 1.06 (4.0°), and a minimum drag coefficient of 0.0062. It carries zero lift at -5.5°.

Performance Metrics
These curves are computed with NeuralFoil, a neural network trained on XFOIL, from a stored sweep across Reynolds number, Ncrit and angle of attack. How the polars are computed, and where they stop being trustworthy →
Run it at your Reynolds number
The curves above are a stored sweep at fixed Reynolds numbers. Enter the one your chord and speed actually give and NeuralFoil computes that polar now, onto this chart.

Ranked on geometry alone, from the stored CST parameters — no polar is consulted, so a section that sits close here can still behave differently at the Reynolds number you fly. A near-symmetric section is matched on thickness and its distribution only: with no camber to speak of, where its camber peaks is rounding error rather than shape.
